Why Phishers Love New TLDs Like .shop, .top and .xyz

Phishing attacks increased nearly 40 percent in the year ending August 2024, with much of that growth concentrated at a small number of new generic top-level domains (gTLDs) — such as .shop, .top, .xyz — that attract scammers with rock-bottom prices and no meaningful registration requirements, new research finds. Meanwhile, the nonprofit entity that oversees the domain name industry is moving forward with plans to introduce a slew of new gTLDs.

A study on phishing data released by Interisle Consulting finds that new gTLDs introduced in the last few years command just 11 percent of the market for new domains, but accounted for roughly 37 percent of cybercrime domains reported between September 2023 and August 2024.

Interisle was sponsored by several anti-spam organizations, including the Anti-Phishing Working Group (APWG), the Coalition Against Unsolicited Commercial Email (CAUCE), and the Messaging, Malware, and Mobile Anti-Abuse Working Group (M3AAWG).

The study finds that while .com and .net domains made up approximately half of all domains registered in the past year (more than all of the other TLDs combined) they accounted for just over 40 percent of all cybercrime domains. Interisle says an almost equal share — 37 percent — of cybercrime domains were registered through new gTLDs.

Spammers and scammers gravitate toward domains in the new gTLDs because these registrars tend to offer cheap or free registration with little to no account or identity verification requirements. For example, among the gTLDs with the highest cybercrime domain scores in this year’s study, nine offered registration fees for less than $1, and nearly two dozen offered fees of less than $2.00. By comparison, the cheapest price identified for a .com domain was $5.91.

Currently, there are around 2,500 registrars authorized to sell domains by the Internet Corporation for Assigned Names and Numbers (ICANN), the California nonprofit that oversees the domain industry.

Incredibly, despite years of these reports showing phishers heavily abusing new gTLDs, ICANN is shuffling forward on a plan to introduce even more of them. ICANN’s proposed next round envisions accepting applications for new gTLDs in 2026.

John Levine is author of the book “The Internet for Dummies” and president of CAUCE. Levine said adding more TLDs without a much stricter registration policy will likely further expand an already plentiful greenfield for cybercriminals.

“The problem is that ICANN can’t make up their mind whether they are the neutral nonprofit regulator or just the domain speculator trade association,” Levine told KrebsOnSecurity. “But they act a lot more like the latter.”

Levine said the vast majority of new gTLDs have a few thousand domains — a far cry from the number of registrations they would need just to cover the up-front costs of operating a new gTLD (~$180,000-$300,000). New gTLD registrars can quickly attract customers by selling domains cheaply to customers who buy domains in bulk, but that tends to be a losing strategy.

“Selling to criminals and spammers turns out to be lousy business,” Levine said. “You can charge whatever you want on the first year, but you have to charge list price on domain renewals. And criminals and spammers never renew. So if it sounds like the economics makes no sense it’s because the economics makes no sense.”

In virtually all previous spam reports, Interisle found the top brands referenced in phishing attacks were the largest technology companies, including Apple, Facebook, Google and PayPal. But this past year, Interisle found the U.S. Postal Service was by far the most-phished entity, with more than four times the number of phishing domains as the second most-frequent target (Apple).

At least some of that increase is likely from a prolific cybercriminal using the nickname Chenlun, who has been selling phishing kits targeting domestic postal services in the United States and at least a dozen other countries.

Interisle says an increasing number of phishers are eschewing domain registrations altogether, and instead taking advantage of subdomain providers like blogspot.com, pages.dev, and weebly.com. The report notes that cyberattacks hosted at subdomain provider services can be tough to mitigate, because only the subdomain provider can disable malicious accounts or take down malicious web pages.

“Any action upstream, such as blocking the second-level domain, would have an impact across the provider’s whole customer base,” the report observes.

Interisle tracked more than 1.18 million instances of subdomains used for phishing in the past year (a 114 percent increase), and found more than half of those were subdomains at blogspot.com and other services operated by Google.

“Many of these services allow the creation of large numbers of accounts at one time, which is highly exploited by criminals,” the report concludes. “Subdomain providers should limit the number of subdomains (user accounts) a customer can create at one time and suspend automated, high-volume automated account sign-ups – especially using free services.”

Feds Charge Five Men in ‘Scattered Spider’ Roundup

Federal prosecutors in Los Angeles this week unsealed criminal charges against five men alleged to be members of a hacking group responsible for dozens of cyber intrusions at major U.S. technology companies between 2021 and 2023, including LastPass, MailChimp, Okta, T-Mobile and Twilio.

The five men, aged 20 to 25, are allegedly members of a hacking conspiracy dubbed “Scattered Spider” and “Oktapus,” which specialized in SMS-based phishing attacks that tricked employees at tech firms into entering their credentials and one-time passcodes at phishing websites.

The targeted SMS scams asked employees to click a link and log in at a website that mimicked their employer’s Okta authentication page. Some SMS phishing messages told employees their VPN credentials were expiring and needed to be changed; other phishing messages advised employees about changes to their upcoming work schedule.

These attacks leveraged newly-registered domains that often included the name of the targeted company, such as twilio-help[.]com and ouryahoo-okta[.]com. The phishing websites were normally kept online for just one or two hours at a time, meaning they were often yanked offline before they could be flagged by anti-phishing and security services.

The phishing kits used for these campaigns featured a hidden Telegram instant message bot that forwarded any submitted credentials in real-time. The bot allowed the attackers to use the phished username, password and one-time code to log in as that employee at the real employer website.

In August 2022, multiple security firms gained access to the server that was receiving data from that Telegram bot, which on several occasions leaked the Telegram ID and handle of its developer, who used the nickname “Joeleoli.”

The Telegram username “Joeleoli” can be seen sandwiched between data submitted by people who knew it was a phish, and data phished from actual victims. Click to enlarge.

That Joeleoli moniker registered on the cybercrime forum OGusers in 2018 with the email address joelebruh@gmail.com, which also was used to register accounts at several websites for a Joel Evans from North Carolina. Indeed, prosecutors say Joeleoli’s real name is Joel Martin Evans, and he is a 25-year-old from Jacksonville, North Carolina.

One of Scattered Spider’s first big victims in its 2022 SMS phishing spree was Twilio, a company that provides services for making and receiving text messages and phone calls. The group then used their access to Twilio to attack at least 163 of its customers. According to prosecutors, the group mainly sought to steal cryptocurrency from victim companies and their employees.

“The defendants allegedly preyed on unsuspecting victims in this phishing scheme and used their personal information as a gateway to steal millions in their cryptocurrency accounts,” said Akil Davis, the assistant director in charge of the FBI’s Los Angeles field office.

Many of the hacking group’s phishing domains were registered through the registrar NameCheap, and FBI investigators said records obtained from NameCheap showed the person who managed those phishing websites did so from an Internet address in Scotland. The feds then obtained records from Virgin Media, which showed the address was leased for several months to Tyler Buchanan, a 22-year-old from Dundee, Scotland.

A Scattered Spider phishing lure sent to Twilio employees.

As first reported here in June, Buchanan was arrested in Spain as he tried to board a flight bound for Italy. The Spanish police told local media that Buchanan, who allegedly went by the alias “Tylerb,” at one time possessed Bitcoins worth $27 million.

The government says much of Tylerb’s cryptocurrency wealth was the result of successful SIM-swapping attacks, wherein crooks transfer the target’s phone number to a device they control and intercept any text messages or phone calls sent to the victim — including one-time passcodes for authentication, or password reset links sent via SMS.

According to several SIM-swapping channels on Telegram where Tylerb was known to frequent, rival SIM-swappers hired thugs to invade his home in February 2023. Those accounts state that the intruders assaulted Tylerb’s mother in the home invasion, and that they threatened to burn him with a blowtorch if he didn’t give up the keys to his cryptocurrency wallets. Tylerb was reputed to have fled the United Kingdom after that assault.

Prosecutors allege Tylerb worked closely on SIM-swapping attacks with Noah Michael Urban, another alleged Scattered Spider member from Palm Coast, Fla. who went by the handles “Sosa,” “Elijah,” and “Kingbob.”

Sosa was known to be a top member of the broader cybercriminal community online known as “The Com,” wherein hackers boast loudly about high-profile exploits and hacks that almost invariably begin with social engineering — tricking people over the phone, email or SMS into giving away credentials that allow remote access to corporate networks.

In January 2024, KrebsOnSecurity broke the news that Urban had been arrested in Florida in connection with multiple SIM-swapping attacks. That story noted that Sosa’s alter ego Kingbob routinely targeted people in the recording industry to steal and share “grails,” a slang term used to describe unreleased music recordings from popular artists.

FBI investigators identified a fourth alleged member of the conspiracy – Ahmed Hossam Eldin Elbadawy, 23, of College Station, Texas — after he used a portion of cryptocurrency funds stolen from a victim company to pay for an account used to register phishing domains.

The indictment unsealed Wednesday alleges Elbadawy controlled a number of cryptocurrency accounts used to receive stolen funds, along with another Texas man — Evans Onyeaka Osiebo, 20, of Dallas.

Members of Scattered Spider are reputed to have been involved in a September 2023 ransomware attack against the MGM Resorts hotel chain that quickly brought multiple MGM casinos to a standstill. In September 2024, KrebsOnSecurity reported that a 17-year-old from the United Kingdom was arrested last year by U.K. police as part of an FBI investigation into the MGM hack.

Evans, Elbadawy, Osiebo and Urban were all charged with one count of conspiracy to commit wire fraud, one count of conspiracy, and one count of aggravated identity theft. Buchanan, who is named as an indicted co-conspirator, was charged with conspiracy to commit wire fraud, conspiracy, wire fraud, and aggravated identity theft.

A Justice Department press release states that if convicted, each defendant would face a statutory maximum sentence of 20 years in federal prison for conspiracy to commit wire fraud, up to five years in federal prison for the conspiracy count, and a mandatory two-year consecutive prison sentence for aggravated identity theft. Buchanan would face up to 20 years in prison for the wire fraud count as well.

The Global Surveillance Free-for-All in Mobile Ad Data

Not long ago, the ability to digitally track someone’s daily movements just by knowing their home address, employer, or place of worship was considered a dangerous power that should remain only within the purview of nation states. But a new lawsuit in a likely constitutional battle over a New Jersey privacy law shows that anyone can now access this capability, thanks to a proliferation of commercial services that hoover up the digital exhaust emitted by widely-used mobile apps and websites.

Delaware-based Atlas Data Privacy Corp. helps its users remove their personal information from the clutches of consumer data brokers, and from people-search services online. Backed by millions of dollars in litigation financing, Atlas so far this year has sued 151 consumer data brokers on behalf of a class that includes more than 20,000 New Jersey law enforcement officers who are signed up for Atlas services.

Atlas alleges all of these data brokers have ignored repeated warnings that they are violating Daniel’s Law, a New Jersey statute allowing law enforcement, government personnel, judges and their families to have their information completely removed from commercial data brokers. Daniel’s Law was passed in 2020 after the death of 20-year-old Daniel Anderl, who was killed in a violent attack targeting a federal judge — his mother.

Last week, Atlas invoked Daniel’s Law in a lawsuit (PDF) against Babel Street, a little-known technology company incorporated in Reston, Va. Babel Street’s core product allows customers to draw a digital polygon around nearly any location on a map of the world, and view a slightly dated (by a few days) time-lapse history of the mobile devices seen coming in and out of the specified area.

Babel Street’s LocateX platform also allows customers to track individual mobile users by their Mobile Advertising ID or MAID, a unique, alphanumeric identifier built into all Google Android and Apple mobile devices.

Babel Street can offer this tracking capability by consuming location data and other identifying information that is collected by many websites and broadcast to dozens and sometimes hundreds of ad networks that may wish to bid on showing their ad to a particular user.

This image, taken from a video recording Atlas made of its private investigator using Babel Street to show all of the unique mobile IDs seen over time at a mosque in Dearborn, Michigan. Each red dot represents one mobile device.

In an interview, Atlas said a private investigator they hired was offered a free trial of Babel Street, which the investigator was able to use to determine the home address and daily movements of mobile devices belonging to multiple New Jersey police officers whose families have already faced significant harassment and death threats.

Atlas said the investigator encountered Babel Street while testing hundreds of data broker tools and services to see if personal information on its users was being sold. They soon discovered Babel Street also bundles people-search services with its platform, to make it easier for customers to zero in on a specific device.

The investigator contacted Babel Street about possibly buying home addresses in certain areas of New Jersey. After listening to a sales pitch for Babel Street and expressing interest, the investigator was told Babel Street only offers their service to the government or to “contractors of the government.”

“The investigator (truthfully) mentioned that he was contemplating some government contract work in the future and was told by the Babel Street salesperson that ‘that’s good enough’ and that ‘they don’t actually check,’” Atlas shared in an email with reporters.

KrebsOnSecurity was one of five media outlets invited to review screen recordings that Atlas made while its investigator used a two-week trial version of Babel Street’s LocateX service. References and links to reporting by other publications, including 404 Media, Haaretz, NOTUS, and The New York Times, will appear throughout this story.

Collectively, these stories expose how the broad availability of mobile advertising data has created a market in which virtually anyone can build a sophisticated spying apparatus capable of tracking the daily movements of hundreds of millions of people globally.

The findings outlined in Atlas’s lawsuit against Babel Street also illustrate how mobile location data is set to massively complicate several hot-button issues, from the tracking of suspected illegal immigrants or women seeking abortions, to harassing public servants who are already in the crosshairs over baseless conspiracy theories and increasingly hostile political rhetoric against government employees.

WARRANTLESS SURVEILLANCE

Atlas says the Babel Street trial period allowed its investigator to find information about visitors to high-risk targets such as mosques, synagogues, courtrooms and abortion clinics. In one video, an Atlas investigator showed how they isolated mobile devices seen in a New Jersey courtroom parking lot that was reserved for jurors, and then tracked one likely juror’s phone to their home address over several days.

While the Atlas investigator had access to its trial account at Babel Street, they were able to successfully track devices belonging to several plaintiffs named or referenced in the lawsuit. They did so by drawing a digital polygon around the home address or workplace of each person in Babel Street’s platform, which focused exclusively on the devices that passed through those addresses each day.

Each red dot in this Babel Street map represents a unique mobile device that has been seen since April 2022 at a Jewish synagogue in Los Angeles, Calif. Image: Atlas Data Privacy Corp.

One unique feature of Babel Street is the ability to toggle a “night” mode, which makes it relatively easy to determine within a few meters where a target typically lays their head each night (because their phone is usually not far away).

Atlas plaintiffs Scott and Justyna Maloney are both veteran officers with the Rahway, NJ police department who live together with their two young children. In April 2023, Scott and Justyna became the target of intense harassment and death threats after Officer Justyna responded to a routine call about a man filming people outside of the Motor Vehicle Commission in Rahway.

The man filming the Motor Vehicle Commission that day is a social media personality who often solicits police contact and then records himself arguing about constitutional rights with the responding officers.

Officer Justyna’s interaction with the man was entirely peaceful, and the episode appeared to end without incident. But after a selectively edited video of that encounter went viral, their home address and unpublished phone numbers were posted online. When their tormentors figured out that Scott was also a cop (a sergeant), the couple began receiving dozens of threatening text messages, including specific death threats.

According to the Atlas lawsuit, one of the messages to Mr. Maloney demanded money, and warned that his family would “pay in blood” if he didn’t comply. Sgt. Maloney said he then received a video in which a masked individual pointed a rifle at the camera and told him that his family was “going to get [their] heads cut off.”

Maloney said a few weeks later, one of their neighbors saw two suspicious individuals in ski masks parked one block away from the home and alerted police. Atlas’s complaint says video surveillance from neighboring homes shows the masked individuals circling the Maloney’s home. The responding officers arrested two men, who were armed, for unlawful possession of a firearm.

According to Google Maps, Babel Street shares a corporate address with Google and the consumer credit reporting bureau TransUnion.

Atlas said their investigator was not able to conclusively find Scott Maloney’s iPhone in the Babel Street platform, but they did find Justyna’s. Babel Street had nearly 100,000 hits for her phone over several months, allowing Atlas to piece together an intimate picture of Justyna’s daily movements and meetings with others.

An Atlas investigator visited the Maloneys and inspected Justyna’s iPhone, and determined the only app that used her device’s location data was from the department store Macy’s.

In a written response to questions, Macy’s said its app includes an opt-in feature for geo-location, “which allows customers to receive an enhanced shopping experience based on their location.”

“We do not store any customer location information,” Macy’s wrote. “We share geo-location data with a limited number of partners who help us deliver this enhanced app experience. Furthermore, we have no connection with Babel Street” [link added for context].

Justyna’s experience highlights a stark reality about the broad availability of mobile location data: Even if the person you’re looking for isn’t directly identifiable in platforms like Babel Street, it is likely that at least some of that person’s family members are. In other words, it’s often trivial to infer the location of one device by successfully locating another.

The terms of service for Babel Street’s Locate X service state that the product “may not be used as the basis for any legal process in any country, including as the basis for a warrant, subpoena, or any other legal or administrative action.” But Scott Maloney said he’s convinced by their experience that not even law enforcement agencies should have access to this capability without a warrant.

“As a law enforcement officer, in order for me to track someone I need a judge to sign a warrant – and that’s for a criminal investigation after we’ve developed probable cause,” Mr. Maloney said in an interview. “Data brokers tracking me and my family just to sell that information for profit, without our consent, and even after we’ve explicitly asked them not to is deeply disturbing.”

Mr. Maloney’s law enforcement colleagues in other states may see things differently. In August, The Texas Observer reported that state police plan to spend more than $5 million on a contract for a controversial surveillance tool called Tangles from the tech firm PenLink. Tangles is an AI-based web platform that scrapes information from the open, deep and dark web, and it has a premier feature called WebLoc that can be used to geofence mobile devices.

The Associated Press reported last month that law enforcement agencies from suburban Southern California to rural North Carolina have been using an obscure cell phone tracking tool called Fog Reveal — at times without warrants — that gives them the ability to follow people’s movements going back many months.

It remains unclear precisely how Babel Street is obtaining the abundance of mobile location data made available to users of its platform. The company did not respond to multiple requests for comment.

But according to a document (PDF) obtained under a Freedom of Information Act request with the Department of Homeland Security’s Science and Technology directorate, Babel Street re-hosts data from the commercial phone tracking firm Venntel.

On Monday, the Substack newsletter All-Source Intelligence unearthed documents indicating that the U.S. Federal Trade Commission has opened an inquiry into Venntel and its parent company Gravy Analytics.

“Venntel has also been a data partner of the police surveillance contractor Fog Data Science, whose product has been described as ‘mass surveillance on a budget,'” All-Source’s Jack Poulson wrote. “Venntel was also reported to have been a primary data source of the controversial ‘Locate X’ phone tracking product of the American data fusion company Babel Street.”

MAID IN HELL

The Mobile Advertising ID or MAID — the unique alphanumeric identifier assigned to each mobile device — was originally envisioned as a way to distinguish individual mobile customers without relying on personally identifiable information such as phone numbers or email addresses.

However, there is now a robust industry of marketing and advertising companies that specialize in assembling enormous lists of MAIDs that are “enriched” with historical and personal information about the individual behind each MAID.

One of many vendors that “enrich” MAID data with other identifying information, including name, address, email address and phone number.

Atlas said its investigator wanted to know whether they could find enriched MAID records on their New Jersey law enforcement customers, and soon found plenty of ad data brokers willing to sell it.

Some vendors offered only a handful of data fields, such as first and last name, MAID and email address. Other brokers sold far more detailed histories along with their MAID, including each subject’s social media profiles, precise GPS coordinates, and even likely consumer category.

How are advertisers and data brokers gaining access to so much information? Some sources of MAID data can be apps on your phone such as AccuWeather, GasBuddy, Grindr, and MyFitnessPal that collect your MAID and location and sell that to brokers.

A user’s MAID profile and location data also is commonly shared as a consequence of simply using a smartphone to visit a web page that features ads. In the few milliseconds before those ads load, the website will send a “bid request” to various ad exchanges, where advertisers can bid on the chance to place their ad in front of users who match the consumer profiles they’re seeking. A great deal of data can be included in a bid request, including the user’s precise location (the current open standard for bid requests is detailed here).

The trouble is that virtually anyone can access the “bidstream” data flowing through these so-called “realtime bidding” networks, because the information is simultaneously broadcast in the clear to hundreds of entities around the world.

The result is that there are a number of marketing companies that now enrich and broker access to this mobile location information. Earlier this year, the German news outlet netzpolitik.org purchased a bidstream data set containing more than 3.6 billion data points, and shared the information with the German daily BR24. They concluded that the data they obtained (through a free trial, no less) made it possible to establish movement profiles — some of them quite precise — of several million people across Germany.

A screenshot from the BR24/Netzpolitik story about their ability to track millions of Germans, including many employees of the German Federal Police and Interior Ministry.

Politico recently covered startling research from universities in New Hampshire, Kentucky and St. Louis that showed how the mobile advertising data they acquired allowed them to link visits from investigators with the U.S. Securities and Exchange Commission (SEC) to insiders selling stock before the investigations became public knowledge.

The researchers in that study said they didn’t attempt to use the same methods to track regulators from other agencies, but that virtually anyone could do it.

Justin Sherman, a distinguished fellow at Georgetown Law’s Center for Privacy and Technology, called the research a “shocking demonstration of what happens when companies can freely harvest Americans’ geolocation data and sell it for their chosen price.”

“Politicians should understand how they, their staff, and public servants are threatened by the sale of personal data—and constituent groups should realize that talk of data broker ‘controls’ or ‘best practices” is designed by companies to distract from the underlying problems and the comprehensive privacy and security solutions,” Sherman wrote for Lawfare this week.

A BIDSTREAM DRAGNET?

The Orwellian nature of modern mobile advertising networks may soon have far-reaching implications for women’s reproductive rights, as more states move to outlaw abortion within their borders. The 2022 Dobbs decision by the U.S. Supreme Court discarded the federal right to abortion, and 14 states have since enacted strict abortion bans.

Anti-abortion groups are already using mobile advertising data to advance their cause. In May 2023, The Wall Street Journal reported that an anti-abortion group in Wisconsin used precise geolocation data to direct ads to women it suspected of seeking abortions.

As it stands, there is little to stop anti-abortion groups from purchasing bidstream data (or renting access to a platform like Babel Street) and using it to geofence abortion clinics, potentially revealing all mobile devices transiting through these locations.

Atlas said its investigator geofenced an abortion clinic and was able to identify a likely employee at that clinic, following their daily route to and from that individual’s home address.

A still shot from a video Atlas shared of its use of Babel Street to identify and track an employee traveling each day between their home and the clinic.

Last year, Idaho became the first state to outlaw “abortion trafficking,” which the Idaho Capital Sun reports is defined as “recruiting, harboring or transporting a pregnant minor to get an abortion or abortion medication without parental permission.” Tennessee now has a similar law, and GOP lawmakers in five other states introduced abortion trafficking bills that failed to advance this year, the Sun reports.

Atlas said its investigator used Babel Street to identify and track a person traveling from their home in Alabama — where abortion is now illegal — to an abortion clinic just over the border in Tallahassee, Fla. — and back home again within a few hours. Abortion rights advocates and providers are currently suing Alabama Attorney General Steve Marshall, seeking to block him from prosecuting people who help patients travel out-of-state to end pregnancies.

Eva Galperin, director of cybersecurity at the Electronic Frontier Foundation (EFF), a non-profit digital rights group, said she’s extremely concerned about dragnet surveillance of people crossing state lines in order to get abortions.

“Specifically, Republican officials from states that have outlawed abortion have made it clear that they are interested in targeting people who have gone to neighboring states in order to get abortions, and to make it more difficult for people who are seeking abortions to go to neighboring states,” Galperin said. “It’s not a great leap to imagine that states will do this.”

APPLES AND GOOGLES

Atlas found that for the right price (typically $10-50k a year), brokers can provide access to tens of billions of data points covering large swaths of the US population and the rest of the world.

Based on the data sets Atlas acquired — many of which included older MAID records — they estimate they could locate roughly 80 percent of Android-based devices, and about 25 percent of Apple phones. Google refers to its MAID as the “Android Advertising ID,” (AAID) while Apple calls it the “Identifier for Advertisers” (IDFA).

What accounts for the disparity between the number of Android and Apple devices that can be found in mobile advertising data? In April 2021, Apple shipped version 14.5 of its iOS operating system, which introduced a technology called App Tracking Transparency (ATT) that requires apps to get affirmative consent before they can track users by their IDFA or any other identifier.

Apple’s introduction of ATT had a swift and profound impact on the advertising market: Less than a year later Facebook disclosed that the iPhone privacy feature would decrease the company’s 2022 revenues by about $10 billion.

Google runs by far the world’s largest ad exchange, known as AdX. The U.S. Department of Justice, which has accused Google of building a monopoly over the technology that places ads on websites, estimates that Google’s ad exchange controls 47 percent of the U.S. market and 56 percent globally.

Google’s Android is also the dominant mobile operating system worldwide, with more than 72 percent of the market. In the U.S., however, iPhone users claim approximately 55 percent of the market, according to TechRepublic.

In response to requests for comment, Google said it does not send real time bidding requests to Babel Street, nor does it share precise location data in bid requests. The company added that its policies explicitly prohibit the sale of data from real-time bidding, or its use for any purpose other than advertising.

Google said its MAIDs are randomly generated and do not contain IP addresses, GPS coordinates, or any other location data, and that its ad systems do not share anyone’s precise location data.

“Android has clear controls for users to manage app access to device location, and reset or delete their advertising ID,” Google’s written statement reads. “If we learn that someone, whether an app developer, ad tech company or anyone else, is violating our policies, we take appropriate action. Beyond that, we support legislation and industry collaboration to address these types of data practices that negatively affect the entire mobile ecosystem, including all operating systems.”

In a written statement shared with reporters, Apple said Location Services is not on by default in its devices. Rather, users must enable Location Services and must give permission to each app or website to use location data. Users can turn Location Services off at any time, and can change whether apps have access to location at any time. The user’s choices include precise vs. approximate location, as well as a one-time grant of location access by the app.

“We believe that privacy is a fundamental human right, and build privacy protections into each of our products and services to put the user in control of their data,” an Apple spokesperson said. “We minimize personal data collection, and where possible, process data only on users’ devices.”

Zach Edwards is a senior threat analyst at the cybersecurity firm SilentPush who has studied the location data industry closely. Edwards said Google and Apple can’t keep pretending like the MAIDs being broadcast into the bidstream from hundreds of millions of American devices aren’t making most people trivially trackable.

“The privacy risks here will remain until Apple and Google permanently turn off their mobile advertising ID schemes and admit to the American public that this is the technology that has been supporting the global data broker ecosystem,” he said.

STATES ACT, WHILE CONGRESS DITHERS

According to Bloomberg Law, between 2019 and 2023, threats against federal judges have more than doubled. Amid increasingly hostile political rhetoric and conspiracy theories against government officials, a growing number of states are seeking to pass their own versions of Daniel’s Law.

Last month, a retired West Virginia police officer filed a class action lawsuit against the people-search service Whitepages for listing their personal information in violation of a statute the state passed in 2021 that largely mirrors Daniel’s Law.

In May 2024, Maryland passed the Judge Andrew F. Wilkinson Judicial Security Act — named after a county circuit court judge who was murdered by an individual involved in a divorce proceeding over which he was presiding. The law allows current and former members of the Maryland judiciary to request their personal information not be made available to the public.

Under the Maryland law, personal information can include a home address; telephone number, email address; Social Security number or federal tax ID number; bank account or payment card number; a license plate or other unique vehicle identifier; a birth or marital record; a child’s name, school, or daycare; place of worship; place of employment for a spouse, child, or dependent.

The law firm Troutman Pepper writes that “so far in 2024, 37 states have begun considering or have adopted similar privacy-based legislation designed to protect members of the judiciary and, in some states, other government officials involved in law enforcement.”

Atlas alleges that in response to requests to have data on its New Jersey law enforcement clients scrubbed from consumer records sold by LexisNexis, the data broker retaliated by freezing the credit of approximately 18,500 people, and falsely reporting them as identity theft victims.

In addition, Atlas said LexisNexis started returning failure codes indicating they had no record of these individuals, resulting in denials when officers attempted to refinance loans or open new bank accounts.

The data broker industry has responded by having at least 70 of the Atlas lawsuits moved to federal court, and challenging the constitutionality of the New Jersey statute as overly broad and a violation of the First Amendment.

Attorneys for the data broker industry argued in their motion to dismiss that there is “no First Amendment doctrine that exempts a content-based restriction from strict scrutiny just because it has some nexus with a privacy interest.”

Atlas’s lawyers responded that data covered under Daniel’s Law — personal information of New Jersey law enforcement officers — is not free speech. Atlas notes that while defending against comparable lawsuits, the data broker industry has argued that home address and phone number data are not “communications.”

“Data brokers should not be allowed to argue that information like addresses are not ‘communications’ in one context, only to turn around and claim that addresses are protectable communications,” Atlas argued (PDF). “Nor can their change of course alter the reality that the data at issue is not speech.”

The judge overseeing the challenge is expected to rule on the motion to dismiss within the next few weeks. Regardless of the outcome, the decision is likely to be appealed all the way to the U.S. Supreme Court.

Meanwhile, media law experts say they’re concerned that enacting Daniel’s Law in other states could limit the ability of journalists to hold public officials accountable, and allow authorities to pursue criminal charges against media outlets that publish the same type of public and government records that fuel the people-search industry.

Sen. Ron Wyden (D-Ore.) said Congress’ failure to regulate data brokers, and the administration’s continued opposition to bipartisan legislation that would limit data sales to law enforcement, have created this current privacy crisis.

“Whether location data is being used to identify and expose closeted gay Americans, or to track people as they cross state lines to seek reproductive health care, data brokers are selling Americans’ deepest secrets and exposing them to serious harm, all for a few bucks,” Wyden said in a statement shared with KrebsOnSecurity, 404 Media, Haaretz, NOTUS, and The New York Times.

Sen. Wyden said Google also deserves blame for refusing to follow Apple’s lead by removing companies’ ability to track phones.

“Google’s insistence on uniquely tracking Android users – and allowing ad companies to do so as well – has created the technical foundations for the surveillance economy and the abuses stemming from it,” Wyden said.

Georgetown Law’s Justin Sherman said the data broker and mobile ad industries claim there are protections in place to anonymize mobile location data and restrict access to it, and that there are limits to the kinds of invasive inferences one can make from location data. The data broker industry also likes to tout the usefulness of mobile location data in fighting retail fraud, he said.

“All kinds of things can be inferred from this data, including people being targeted by abusers, or people with a particular health condition or religious belief,” Sherman said. “You can track jurors, law enforcement officers visiting the homes of suspects, or military intelligence people meeting with their contacts. The notion that the sale of all this data is preventing harm and fraud is hilarious in light of all the harm it causes enabling people to better target their cyber operations, or learning about people’s extramarital affairs and extorting public officials.”

WHAT CAN YOU DO?

Privacy experts say disabling or deleting your device’s MAID will have no effect on how your phone operates, except that you may begin to see far less targeted ads on that device.

Any Android apps with permission to use your location should appear when you navigate to the Settings app, Location, and then App Permissions. “Allowed all the time” is the most permissive setting, followed by “Allowed only while in use,” “Ask every time,” and “Not allowed.”

Android users can delete their ad ID permanently, by opening the Settings app and navigating to Privacy > Ads. Tap “Delete advertising ID,” then tap it again on the next page to confirm. According to the EFF, this will prevent any app on your phone from accessing the ad ID in the future. Google’s documentation on this is here.

By default, Apple’s iOS requires apps to ask permission before they can access your device’s IDFA. When you install a new app, it may ask for permission to track you. When prompted to do so by an app, select the “Ask App Not to Track” option. Apple users also can set the “Allow apps to request to track” switch to the “off” position, which will block apps from asking to track you.

Apple’s Privacy and Ad Tracking Settings.

Apple also has its own targeted advertising system which is separate from third-party tracking enabled by the IDFA. To disable it, go to Settings, Privacy, and Apple Advertising, and ensure that the “Personalized Ads” setting is set to “off.”

Finally, if you’re the type of reader who’s the default IT support person for a small group of family or friends (bless your heart), it would be a good idea to set their devices not to track them, and to disable any apps that may have location data sharing turned on 24/7.

There is a dual benefit to this altruism, which is clearly in the device owner’s best interests. Because while your device may not be directly trackable via advertising data, making sure they’re opted out of said tracking also can reduce the likelihood that you are trackable simply by being physically close to those who are.

Patch Tuesday, October 2024 Edition

Microsoft today released security updates to fix at least 117 security holes in Windows computers and other software, including two vulnerabilities that are already seeing active attacks. Also, Adobe plugged 52 security holes across a range of products, and Apple has addressed a bug in its new macOS 15Sequoia” update that broke many cybersecurity tools.

One of the zero-day flaws — CVE-2024-43573 — stems from a security weakness in MSHTML, the proprietary engine of Microsoft’s Internet Explorer web browser. If that sounds familiar it’s because this is the fourth MSHTML vulnerability found to be exploited in the wild so far in 2024.

Nikolas Cemerikic, a cybersecurity engineer at Immersive Labs, said the vulnerability allows an attacker to trick users into viewing malicious web content, which could appear legitimate thanks to the way Windows handles certain web elements.

“Once a user is deceived into interacting with this content (typically through phishing attacks), the attacker can potentially gain unauthorized access to sensitive information or manipulate web-based services,” he said.

Cemerikic noted that while Internet Explorer is being retired on many platforms, its underlying MSHTML technology remains active and vulnerable.

“This creates a risk for employees using these older systems as part of their everyday work, especially if they are accessing sensitive data or performing financial transactions online,” he said.

Probably the more serious zero-day this month is CVE-2024-43572, a code execution bug in the Microsoft Management Console, a component of Windows that gives system administrators a way to configure and monitor the system.

Satnam Narang, senior staff research engineer at Tenable, observed that the patch for CVE-2024-43572 arrived a few months after researchers at Elastic Security Labs disclosed an attack technique called GrimResource that leveraged an old cross-site scripting (XSS) vulnerability combined with a specially crafted Microsoft Saved Console (MSC) file to gain code execution privileges.

“Although Microsoft patched a different MMC vulnerability in September (CVE-2024-38259) that was neither exploited in the wild nor publicly disclosed,” Narang said. “Since the discovery of CVE-2024-43572, Microsoft now prevents untrusted MSC files from being opened on a system.”

Microsoft also patched Office, Azure, .NET, OpenSSH for Windows; Power BI; Windows Hyper-V; Windows Mobile Broadband, and Visual Studio. As usual, the SANS Internet Storm Center has a list of all Microsoft patches released today, indexed by severity and exploitability.

Late last month, Apple rolled out macOS 15, an operating system update called Sequoia that broke the functionality of security tools made by a number of vendors, including CrowdStrike, SentinelOne and Microsoft. On Oct. 7, Apple pushed an update to Sequoia users that addresses these compatibility issues.

Finally, Adobe has released security updates to plug a total of 52 vulnerabilities in a range of software, including Adobe Substance 3D Painter, Commerce, Dimension, Animate, Lightroom, InCopy, InDesign, Substance 3D Stager, and Adobe FrameMaker.

Please consider backing up important data before applying any updates. Zero-days aside, there’s generally little harm in waiting a few days to apply any pending patches, because not infrequently a security update introduces stability or compatibility issues. AskWoody.com usually has the skinny on any problematic patches.

And as always, if you run into any glitches after installing patches, leave a note in the comments; chances are someone else is stuck with the same issue and may have even found a solution.

The Dark Nexus Between Harm Groups and ‘The Com’

A cyberattack that shut down two of the top casinos in Las Vegas last year quickly became one of the most riveting security stories of 2023. It was the first known case of native English-speaking hackers in the United States and Britain teaming up with ransomware gangs based in Russia. But that made-for-Hollywood narrative has eclipsed a far more hideous trend: Many of these young, Western cybercriminals are also members of fast-growing online groups that exist solely to bully, stalk, harass and extort vulnerable teens into physically harming themselves and others.

In September 2023, a Russian ransomware group known as ALPHV/Black Cat claimed credit for an intrusion at the MGM Resorts hotel chain that quickly brought MGM’s casinos in Las Vegas to a standstill. While MGM was still trying to evict the intruders from its systems, an individual who claimed to have firsthand knowledge of the hack contacted multiple media outlets to offer interviews about how it all went down.

One account of the hack came from a 17-year-old in the United Kingdom, who told reporters the intrusion began when one of the English-speaking hackers phoned a tech support person at MGM and tricked them into resetting the password for an employee account.

The security firm CrowdStrike dubbed the group “Scattered Spider,” a recognition that the MGM hackers came from different cliques scattered across an ocean of Telegram and Discord servers dedicated to financially-oriented cybercrime.

Collectively, this archipelago of crime-focused chat communities is known as “The Com,” and it functions as a kind of distributed cybercriminal social network that facilitates instant collaboration.

But mostly, The Com is a place where cybercriminals go to boast about their exploits and standing within the community, or to knock others down a peg or two. Top Com members are constantly sniping over who pulled off the most impressive heists, or who has accumulated the biggest pile of stolen virtual currencies.

And as often as they extort victim companies for financial gain, members of The Com are trying to wrest stolen money from their cybercriminal rivals — often in ways that spill over into physical violence in the real world.

CrowdStrike would go on to produce and sell Scattered Spider action figures, and it featured a life-sized Scattered Spider sculpture at this year’s RSA Security Conference in San Francisco.

But marketing security products and services based on specific cybercriminal groups can be tricky, particularly if it turns out that robbing and extorting victims is by no means the most abhorrent activity those groups engage in on a daily basis.

KrebsOnSecurity examined the Telegram user ID number of the account that offered media interviews about the MGM hack — which corresponds to the screen name “@Holy” — and found the same account was used across a number of cybercrime channels that are entirely focused on extorting young people into harming themselves or others, and recording the harm on video.

HOLY NAZI

Holy was known to possess multiple prized Telegram usernames, including @bomb, @halo, and @cute, as well as one of the highest-priced Telegram usernames ever put up for sale: @nazi.

In one post on a Telegram channel dedicated to youth extortion, this same user can be seen asking if anyone knows the current Telegram handles for several core members of 764, an extremist group known for victimizing children through coordinated online campaigns of extortion, doxing, swatting and harassment.

People affiliated with harm groups like 764 will often recruit new members by lurking on gaming platforms, social media sites and mobile applications that are popular with young people, including Discord, Minecraft, Roblox, Steam, Telegram, and Twitch.

“This type of offence usually starts with a direct message through gaming platforms and can move to more private chatrooms on other virtual platforms, typically one with video enabled features, where the conversation quickly becomes sexualized or violent,” warns a recent alert from the Royal Canadian Mounted Police (RCMP) about the rise of sextortion groups on social media channels.

“One of the tactics being used by these actors is sextortion, however, they are not using it to extract money or for sexual gratification,” the RCMP continued. “Instead they use it to further manipulate and control victims to produce more harmful and violent content as part of their ideological objectives and radicalization pathway.”

The 764 network is among the most populated harm communities, but there are plenty more. Some of the largest such known groups include CVLT, Court, Kaskar, Leak Society, 7997, 8884, 2992, 6996, 555, Slit Town, 545, 404, NMK, 303, and H3ll.

In March, a consortium of reporters from Wired, Der Spiegel, Recorder and The Washington Post examined millions of messages across more than 50 Discord and Telegram chat groups.

“The abuse perpetrated by members of com groups is extreme,” Wired’s Ali Winston wrote. “They have coerced children into sexual abuse or self-harm, causing them to deeply lacerate their bodies to carve ‘cutsigns’ of an abuser’s online alias into their skin.” The story continues:

“Victims have flushed their heads in toilets, attacked their siblings, killed their pets, and in some extreme instances, attempted or died by suicide. Court records from the United States and European nations reveal participants in this network have also been accused of robberies, in-person sexual abuse of minors, kidnapping, weapons violations, swatting, and murder.”

“Some members of the network extort children for sexual pleasure, some for power and control. Some do it merely for the kick that comes from manipulation. Others sell the explicit CSAM content produced by extortion on the dark web.”

KrebsOnSecurity has learned Holy is the 17-year-old who was arrested in July 2024 by the U.K.’s West Midlands Police as part of a joint investigation with the FBI into the MGM hack.

Early in their cybercriminal career (as a 15-year-old), @Holy went by the handle “Vsphere,” and was a proud member of the LAPSUS$ cybercrime group. Throughout 2022, LAPSUS$ would hack and social engineer their way into some of the world’s biggest technology companies, including EA Games, Microsoft, NVIDIA, Okta, Samsung, and T-Mobile.

JUDISCHE/WAIFU

Another timely example of the overlap between harm communities and top members of The Com can be found in a group of criminals who recently stole obscene amounts of customer records from users of the cloud data provider Snowflake.

At the end of 2023, malicious hackers figured out that many major companies have uploaded massive amounts of valuable and sensitive customer data to Snowflake servers, all the while protecting those Snowflake accounts with little more than a username and password (no multi-factor authentication required). The group then searched darknet markets for stolen Snowflake account credentials, and began raiding the data storage repositories used by some of the world’s largest corporations.

Among those that had data exposed in Snowflake was AT&T, which disclosed in July that cybercriminals had stolen personal information and phone and text message records for roughly 110 million people — nearly all its customers.

A report on the extortion group from the incident response firm Mandiant notes that Snowflake victim companies were privately approached by the hackers, who demanded a ransom in exchange for a promise not to sell or leak the stolen data. All told, more than 160 organizations were extorted, including TicketMaster, Lending Tree, Advance Auto Parts and Neiman Marcus.

On May 2, 2024, a user by the name “Judische” claimed on the fraud-focused Telegram channel Star Chat that they had hacked Santander Bank, one of the first known Snowflake victims. Judische would repeat that claim in Star Chat on May 13 — the day before Santander publicly disclosed a data breach — and would periodically blurt out the names of other Snowflake victims before their data even went up for sale on the cybercrime forums.

A careful review of Judische’s account history and postings on Telegram shows this user is more widely known under the nickname “Waifu,” an early moniker that corresponds to one of the more accomplished SIM-swappers in The Com over the years.

In a SIM-swapping attack, the fraudsters will phish or purchase credentials for mobile phone company employees, and use those credentials to redirect a target’s mobile calls and text messages to a device the attackers control.

Several channels on Telegram maintain a frequently updated leaderboard of the 100 richest SIM-swappers, as well as the hacker handles associated with specific cybercrime groups (Waifu is ranked #24). That leaderboard has long included Waifu on a roster of hackers for a group that called itself “Beige.”

Beige members were implicated in two stories published here in 2020. The first was an August 2020 piece called Voice Phishers Targeting Corporate VPNs, which warned that the COVID-19 epidemic had brought a wave of voice phishing or “vishing” attacks that targeted work-from-home employees via their mobile devices, and tricked many of those people into giving up credentials needed to access their employer’s network remotely.

Beige group members also have claimed credit for a breach at the domain registrar GoDaddy. In November 2020, intruders thought to be associated with the Beige Group tricked a GoDaddy employee into installing malicious software, and with that access they were able to redirect the web and email traffic for multiple cryptocurrency trading platforms.

The Telegram channels that Judische and his related accounts frequented over the years show this user divides their time between posting in SIM-swapping and cybercrime cashout channels, and harassing and stalking others in harm communities like Leak Society and Court.

Mandiant has attributed the Snowflake compromises to a group it calls “UNC5537,” with members based in North America and Turkey. KrebsOnSecurity has learned Judische is a 26-year-old software engineer in Ontario, Canada.

Sources close to the investigation into the Snowflake incident tell KrebsOnSecurity the UNC5537 member in Turkey is John Erin Binns, an elusive American man indicted by the U.S. Department of Justice (DOJ) for a 2021 breach at T-Mobile that exposed the personal information of at least 76.6 million customers.

Binns is currently in custody in a Turkish prison and fighting his extradition. Meanwhile, he has been suing almost every federal agency and agent that contributed investigative resources to his case.

In June 2024, a Mandiant employee told Bloomberg that UNC5537 members have made death threats against cybersecurity experts investigating the hackers, and that in one case the group used artificial intelligence to create fake nude photos of a researcher to harass them.

ViLE

In June 2024, two American men pleaded guilty to hacking into a U.S. Drug Enforcement Agency (DEA) online portal that tapped into 16 different federal law enforcement databasesSagar “Weep” Singh, a 20-year-old from Rhode Island, and Nicholas “Convict” Ceraolo, 25, of Queens, NY, were both active in SIM-swapping communities.

Singh and Ceraolo hacked into a number of foreign police department email accounts, and used them to make phony “emergency data requests” to social media platforms seeking account information about specific users they were stalking. According to the government, in each case the men impersonating the foreign police departments told those platforms the request was urgent because the account holders had been trading in child pornography or engaging in child extortion.

Eventually, the two men formed part of a group of cybercriminals known to its members as “ViLE,” who specialize in obtaining personal information about third-party victims, which they then used to harass, threaten or extort the victims, a practice known as “doxing.”

The U.S. government says Singh and Ceraolo worked closely with a third man — referenced in the indictment as co-conspirator #1 or “CC-1” — to administer a doxing forum where victims could pay to have their personal information removed.

The government doesn’t name CC-1 or the doxing forum, but CC-1’s hacker handle is “Kayte” (a.k.a. “KT“) which corresponds to the nickname of a 23-year-old man who lives with his parents in Coffs Harbor, Australia. For several years (with a brief interruption), KT has been the administrator of a truly vile doxing community known as the Doxbin.

People whose names and personal information appear on the Doxbin can quickly find themselves the target of extended harassment campaigns, account hacking, SIM-swapping and even swatting — which involves falsely reporting a violent incident at a target’s address to trick local police into responding with potentially deadly force.

A handful of Com members targeted by federal authorities have gone so far as to perpetrate swatting, doxing, and other harassment against the same federal agents who are trying to unravel their alleged crimes. This has led some investigators working cases involving the Com to begin redacting their names from affidavits and indictments filed in federal court.

In January 2024, KrebsOnSecurity broke the news that prosecutors in Florida had charged a 19-year-old alleged Scattered Spider member named Noah Michael Urban with wire fraud and identity theft. That story recounted how Urban’s alleged hacker identities “King Bob” and “Sosa” inhabited a world in which rival cryptocurrency theft rings frequently settled disputes through so-called “violence-as-a-service” offerings — hiring strangers online to perpetrate firebombings, beatings and kidnappings against their rivals.

Urban’s indictment shows the name of the federal agent who testified to it has been blacked out:

The final page of Noah Michael Urban’s indictment shows the investigating agent redacted their name from charging documents.

HACKING RINGS, STALKING VICTIMS

In June 2022, this blog told the story of two men charged with hacking into the Ring home security cameras of a dozen random people and then methodically swatting each of them. Adding insult to injury, the men used the compromised security cameras to record live footage of local police swarming those homes.

McCarty, in a mugshot.

James Thomas Andrew McCarty, Charlotte, N.C., and Kya “Chumlul” Nelson, of Racine, Wisc., conspired to hack into Yahoo email accounts belonging to victims in the United States. The two would check how many of those Yahoo accounts were associated with Ring accounts, and then target people who used the same password for both accounts.

The Telegram and Discord aliases allegedly used by McCarty — “Aspertaine” and “Couch,” among others — correspond to an identity that was active in certain channels dedicated to SIM-swapping.

What KrebsOnSecurity didn’t report at the time is that both ChumLul and Aspertaine were active members of CVLT, wherein those identities clearly participated in harassing and exploiting young teens online.

In June 2024, McCarty was sentenced to seven years in prison after pleading guilty to making hoax calls that elicited police SWAT responses. Nelson also pleaded guilty and received a seven-year prison sentence.

POMPOMPURIN

In March 2023, U.S. federal agents in New York announced they’d arrested “Pompompurin,” the alleged administrator of Breachforums, an English-language cybercrime forum where hacked corporate databases frequently appear for sale. In cases where the victim organization isn’t extorted in advance by hackers, being listed on Breachforums has often been the way many victims first learned of an intrusion.

Pompompurin had been a nemesis to the FBI for several years. In November 2021, KrebsOnSecurity broke the news that thousands of fake emails about a cybercrime investigation were blasted out from the FBI’s email systems and Internet addresses.

Pompompurin took credit for that stunt, and said he was able to send the FBI email blast by exploiting a flaw in an FBI portal designed to share information with state and local law enforcement authorities. The FBI later acknowledged that a software misconfiguration allowed someone to send the fake emails.

In December, 2022, KrebsOnSecurity detailed how hackers active on BreachForums had infiltrated the FBI’s InfraGard program, a vetted network designed to build cyber and physical threat information sharing partnerships with experts in the private sector. The hackers impersonated the CEO of a major financial company, applied for InfraGard membership in the CEO’s name, and were granted admission to the community.

The feds named Pompompurin as 21-year-old Peekskill resident Conor Brian Fitzpatrick, who was originally charged with one count of conspiracy to solicit individuals to sell unauthorized access devices (stolen usernames and passwords). But after FBI agents raided and searched the home where Fitzpatrick lived with his parents, prosecutors tacked on charges for possession of child pornography.

DOMESTIC TERRORISM?

Recent actions by the DOJ indicate the government is well aware of the significant overlap between leading members of The Com and harm communities. But the government also is growing more sensitive to the criticism that it can often take months or years to gather enough evidence to criminally charge some of these suspects, during which time the perpetrators can abuse and recruit countless new victims.

Late last year, however, the DOJ signaled a new tactic in pursuing leaders of harm communities like 764: Charging them with domestic terrorism.

In December 2023, the government charged (PDF) a Hawaiian man with possessing and sharing sexually explicit videos and images of prepubescent children being abused. Prosecutors allege Kalana Limkin, 18, of Hilo, Hawaii, admitted he was an associate of CVLT and 764, and that he was the founder of a splinter harm group called Cultist. Limkin’s Telegram profile shows he also was active on the harm community Slit Town.

The relevant citation from Limkin’s complaint reads:

“Members of the group ‘764’ have conspired and continue to conspire in both online and in-person venues to engage in violent actions in furtherance of a Racially Motivated Violent Extremist ideology, wholly or in part through activities that violate federal criminal law meeting the statutory definition of Domestic Terrorism, defined in Title 18, United States Code, § 2331.”

Experts say charging harm groups under anti-terrorism statutes potentially gives the government access to more expedient investigative powers than it would normally have in a run-of-the-mill criminal hacking case.

“What it ultimately gets you is additional tools you can use in the investigation, possibly warrants and things like that,” said Mark Rasch, a former U.S. federal cybercrime prosecutor and now general counsel for the New York-based cybersecurity firm Unit 221B. “It can also get you additional remedies at the end of the case, like greater sanctions, more jail time, fines and forfeiture.”

But Rasch said this tactic can backfire on prosecutors who overplay their hand and go after someone who ends up challenging the charges in court.

“If you’re going to charge a hacker or pedophile with a crime like terrorism, that’s going to make it harder to get a conviction,” Rasch said. “It adds to the prosecutorial burden and increases the likelihood of getting an acquittal.”

Rasch said it’s unclear where it is appropriate to draw the line in the use of terrorism statutes to disrupt harm groups online, noting that there certainly are circumstances where individuals can commit violations of domestic anti-terrorism statutes through their Internet activity alone.

“The Internet is a platform like any other, where virtually any kind of crime that can be committed in the real world can also be committed online,” he said. “That doesn’t mean all misuse of computers fits within the statutory definition of terrorism.”

The RCMP’s advisory on sexual extortion of minors over the Internet lists a number of potential warning signs that teens may exhibit if they become entangled in these harm groups. The FBI urges anyone who believes their child or someone they know is being exploited to contact their local FBI field office, call 1-800-CALL-FBI, or report it online at tips.fbi.gov.

FCC Fines Major U.S. Wireless Carriers for Selling Customer Location Data

The U.S. Federal Communications Commission (FCC) today levied fines totaling nearly $200 million against the four major carriers — including AT&T, Sprint, T-Mobile and Verizon — for illegally sharing access to customers’ location information without consent.

The fines mark the culmination of a more than four-year investigation into the actions of the major carriers. In February 2020, the FCC put all four wireless providers on notice that their practices of sharing access to customer location data were likely violating the law.

The FCC said it found the carriers each sold access to its customers’ location information to ‘aggregators,’ who then resold access to the information to third-party location-based service providers.

“In doing so, each carrier attempted to offload its obligations to obtain customer consent onto downstream recipients of location information, which in many instances meant that no valid customer consent was obtained,” an FCC statement on the action reads. “This initial failure was compounded when, after becoming aware that their safeguards were ineffective, the carriers continued to sell access to location information without taking reasonable measures to protect it from unauthorized access.”

The FCC’s findings against AT&T, for example, show that AT&T sold customer location data directly or indirectly to at least 88 third-party entities. The FCC found Verizon sold access to customer location data (indirectly or directly) to 67 third-party entities. Location data for Sprint customers found its way to 86 third-party entities, and to 75 third-parties in the case of T-Mobile customers.

The commission said it took action after Sen. Ron Wyden (D-Ore.) sent a letter to the FCC detailing how a company called Securus Technologies had been selling location data on customers of virtually any major mobile provider to law enforcement officials.

That same month, KrebsOnSecurity broke the news that LocationSmart — a data aggregation firm working with the major wireless carriers — had a free, unsecured demo of its service online that anyone could abuse to find the near-exact location of virtually any mobile phone in North America.

The carriers promised to “wind down” location data sharing agreements with third-party companies. But in 2019, reporting at Vice.com showed that little had changed, detailing how reporters were able to locate a test phone after paying $300 to a bounty hunter who simply bought the data through a little-known third-party service.

Sen. Wyden said no one who signed up for a cell plan thought they were giving permission for their phone company to sell a detailed record of their movements to anyone with a credit card.

“I applaud the FCC for following through on my investigation and holding these companies accountable for putting customers’ lives and privacy at risk,” Wyden said in a statement today.

The FCC fined Sprint and T-Mobile $12 million and $80 million respectively. AT&T was fined more than $57 million, while Verizon received a $47 million penalty. Still, these fines represent a tiny fraction of each carrier’s annual revenues. For example, $47 million is less than one percent of Verizon’s total wireless service revenue in 2023, which was nearly $77 billion.

The fine amounts vary because they were calculated based in part on the number of days that the carriers continued sharing customer location data after being notified that doing so was illegal (the agency also considered the number of active third-party location data sharing agreements). The FCC notes that AT&T and Verizon each took more than 320 days from the publication of the Times story to wind down their data sharing agreements; T-Mobile took 275 days; Sprint kept sharing customer location data for 386 days.

Update, 6:25 p.m. ET: Clarified that the FCC launched its investigation at the request of Sen. Wyden.

Kroll Employee SIM-Swapped for Crypto Investor Data

Security consulting giant Kroll disclosed today that a SIM-swapping attack against one of its employees led to the theft of user information for multiple cryptocurrency platforms that are relying on Kroll services in their ongoing bankruptcy proceedings. And there are indications that fraudsters may already be exploiting the stolen data in phishing attacks.

Cryptocurrency lender BlockFi and the now-collapsed crypto trading platform FTX each disclosed data breaches this week thanks to a recent SIM-swapping attack targeting an employee of Kroll — the company handling both firms’ bankruptcy restructuring.

In a statement released today, New York City-based Kroll said it was informed that on Aug. 19, 2023, someone targeted a T-Mobile phone number belonging to a Kroll employee “in a highly sophisticated ‘SIM swapping’ attack.”

“Specifically, T-Mobile, without any authority from or contact with Kroll or its employees, transferred that employee’s phone number to the threat actor’s phone at their request,” the statement continues. “As a result, it appears the threat actor gained access to certain files containing personal information of bankruptcy claimants in the matters of BlockFi, FTX and Genesis.”

T-Mobile has not yet responded to requests for comment.

Countless websites and online services use SMS text messages for both password resets and multi-factor authentication. This means that stealing someone’s phone number often can let cybercriminals hijack the target’s entire digital life in short order — including access to any financial, email and social media accounts tied to that phone number.

SIM-swapping groups will often call employees on their mobile devices, pretend to be someone from the company’s IT department, and then try to get the employee to visit a phishing website that mimics the company’s login page.

Multiple SIM-swapping gangs have had great success using this method to target T-Mobile employees for the purposes of reselling a cybercrime service that can be hired to divert any T-Mobile user’s text messages and phone calls to another device.

In February 2023, KrebsOnSecurity chronicled SIM-swapping attacks claimed by these groups against T-Mobile employees in more than 100 separate incidents in the second half of 2022. The average cost to SIM swap any T-Mobile phone number was approximately $1,500.

The unfortunate result of the SIM-swap against the Kroll employee is that people who had financial ties to BlockFi, FTX, or Genesis now face increased risk of becoming targets of SIM-swapping and phishing attacks themselves.

And there is some indication this is already happening. Multiple readers who said they got breach notices from Kroll today also shared phishing emails they received this morning that spoofed FTX and claimed, “You have been identified as an eligible client to begin withdrawing digital assets from your FTX account.”

A phishing message targeting FTX users that went out en masse today.

A major portion of Kroll’s business comes from helping organizations manage cyber risk. Kroll is often called in to investigate data breaches, and it also sells identity protection services to companies that recently experienced a breach and are grasping at ways to demonstrate that they doing something to protect their customers from further harm.

Kroll did not respond to questions. But it’s a good bet that BlockFi, FTX and Genesis customers will soon enjoy yet another offering of free credit monitoring as a result of the T-Mobile SIM swap.

Kroll’s website says it employs “elite cyber risk leaders uniquely positioned to deliver end-to-end cyber security services worldwide.” Apparently, these elite cyber risk leaders did not consider the increased attack surface presented by their employees using T-Mobile for wireless service.

The SIM-swapping attack against Kroll is a timely reminder that you should do whatever you can to minimize your reliance on mobile phone companies for your security. For example, many online services require you to provide a phone number upon registering an account, but that number can often be removed from your profile afterwards.

Why do I suggest this? Many online services allow users to reset their passwords just by clicking a link sent via SMS, and this unfortunately widespread practice has turned mobile phone numbers into de facto identity documents. Which means losing control over your phone number thanks to an unauthorized SIM swap or mobile number port-out, divorce, job termination or financial crisis can be devastating.

If you haven’t done so lately, take a moment to inventory your most important online accounts, and see how many of them can still have their password reset by receiving an SMS at the phone number on file. This may require stepping through the website’s account recovery or lost password flow.

If the account that stores your mobile phone number does not allow you to delete your number, check to see whether there is an option to disallow SMS or phone calls for authentication and account recovery. If more secure options are available, such as a security key or a one-time code from a mobile authentication app, please take advantage of those instead. The website 2fa.directory is a good starting point for this analysis.

Now, you might think that the mobile providers would share some culpability when a customer suffers a financial loss because a mobile store employee got tricked into transferring that customer’s phone number to criminals. But earlier this year, a California judge dismissed a lawsuit against AT&T that stemmed from a 2017 SIM-swapping attack which netted the thieves more than $24 million in cryptocurrency.

Why You Should Opt Out of Sharing Data With Your Mobile Provider

A new breach involving data from nine million AT&T customers is a fresh reminder that your mobile provider likely collects and shares a great deal of information about where you go and what you do with your mobile device — unless and until you affirmatively opt out of this data collection. Here’s a primer on why you might want to do that, and how.

Telecommunications giant AT&T disclosed this month that a breach at a marketing vendor exposed certain account information for nine million customers. AT&T said the data exposed did not include sensitive information, such as credit card or Social Security numbers, or account passwords, but was limited to “Customer Proprietary Network Information” (CPNI), such as the number of lines on an account.

Certain questions may be coming to mind right now, like “What the heck is CPNI?” And, ‘If it’s so ‘customer proprietary,’ why is AT&T sharing it with marketers?” Also maybe, “What can I do about it?” Read on for answers to all three questions.

AT&T’s disclosure said the information exposed included customer first name, wireless account number, wireless phone number and email address. In addition, a small percentage of customer records also exposed the rate plan name, past due amounts, monthly payment amounts and minutes used.

CPNI refers to customer-specific “metadata” about the account and account usage, and may include:

-Called phone numbers
-Time of calls
-Length of calls
-Cost and billing of calls
-Service features
-Premium services, such as directory call assistance

According to a succinct CPNI explainer at TechTarget, CPNI is private and protected information that cannot be used for advertising or marketing directly.

“An individual’s CPNI can be shared with other telecommunications providers for network operating reasons,” wrote TechTarget’s Gavin Wright. “So, when the individual first signs up for phone service, this information is automatically shared by the phone provider to partner companies.”

Is your mobile Internet usage covered by CPNI laws? That’s less clear, as the CPNI rules were established before mobile phones and wireless Internet access were common. TechTarget’s CPNI primer explains:

“Under current U.S. law, cellphone use is only protected as CPNI when it is being used as a telephone. During this time, the company is acting as a telecommunications provider requiring CPNI rules. Internet use, websites visited, search history or apps used are not protected CPNI because the company is acting as an information services provider not subject to these laws.”

Hence, the carriers can share and sell this data because they’re not explicitly prohibited from doing so. All three major carriers say they take steps to anonymize the customer data they share, but researchers have shown it is not terribly difficult to de-anonymize supposedly anonymous web-browsing data.

“Your phone, and consequently your mobile provider, know a lot about you,” wrote Jack Morse for Mashable. “The places you go, apps you use, and the websites you visit potentially reveal all kinds of private information — e.g. religious beliefs, health conditions, travel plans, income level, and specific tastes in pornography. This should bother you.”

Happily, all of the U.S. carriers are required to offer customers ways to opt out of having data about how they use their devices shared with marketers. Here’s a look at some of the carrier-specific practices and opt-out options.

AT&T

AT&T’s policy says it shares device or “ad ID”, combined with demographics including age range, gender, and ZIP code information with third parties which explicitly include advertisers, programmers, and networks, social media networks, analytics firms, ad networks and other similar companies that are involved in creating and delivering advertisements.

AT&T said the data exposed on 9 million customers was several years old, and mostly related to device upgrade eligibility. This may sound like the data went to just one of its partners who experienced a breach, but in all likelihood it also went to hundreds of AT&T’s partners.

AT&T’s CPNI opt-out page says it shares CPNI data with several of its affiliates, including WarnerMedia, DirecTV and Cricket Wireless. Until recently, AT&T also shared CPNI data with Xandr, whose privacy policy in turn explains that it shares data with hundreds of other advertising firms. Microsoft bought Xandr from AT&T last year.

T-MOBILE

According to the Electronic Privacy Information Center (EPIC), T-Mobile seems to be the only company out of the big three to extend to all customers the rights conferred by the California Consumer Privacy Act (CCPA).

EPIC says T-Mobile customer data sold to third parties uses another unique identifier called mobile advertising IDs or “MAIDs.” T-Mobile claims that MAIDs don’t directly identify consumers, but under the CCPA MAIDs are considered “personal information” that can be connected to IP addresses, mobile apps installed or used with the device, any video or content viewing information, and device activity and attributes.

T-Mobile customers can opt out by logging into their account and navigating to the profile page, then to “Privacy and Notifications.” From there, toggle off the options for “Use my data for analytics and reporting” and “Use my data to make ads more relevant to me.”

VERIZON

Verizon’s privacy policy says it does not sell information that personally identities customers (e.g., name, telephone number or email address), but it does allow third-party advertising companies to collect information about activity on Verizon websites and in Verizon apps, through MAIDs, pixels, web beacons and social network plugins.

According to Wired.com’s tutorial, Verizon users can opt out by logging into their Verizon account through a web browser or the My Verizon mobile app. From there, select the Account tab, then click Account Settings and Privacy Settings on the web. For the mobile app, click the gear icon in the upper right corner and then Manage Privacy Settings.

On the privacy preferences page, web users can choose “Don’t use” under the Custom Experience section. On the My Verizon app, toggle any green sliders to the left.

EPIC notes that all three major carriers say resetting the consumer’s device ID and/or clearing cookies in the browser will similarly reset any opt-out preferences (i.e., the customer will need to opt out again), and that blocking cookies by default may also block the opt-out cookie from being set.

T-Mobile says its opt out is device-specific and/or browser-specific. “In most cases, your opt-out choice will apply only to the specific device or browser on which it was made. You may need to separately opt out from your other devices and browsers.”

Both AT&T and Verizon offer opt-in programs that gather and share far more information, including device location, the phone numbers you call, and which sites you visit using your mobile and/or home Internet connection. AT&T calls this their Enhanced Relevant Advertising Program; Verizon’s is called Custom Experience Plus.

In 2021, multiple media outlets reported that some Verizon customers were being automatically enrolled in Custom Experience Plus — even after those customers had already opted out of the same program under its previous name — “Verizon Selects.”

If none of the above opt out options work for you, at a minimum you should be able to opt out of CPNI sharing by calling your carrier, or by visiting one of their stores.

THE CASE FOR OPTING OUT

Why should you opt out of sharing CPNI data? For starters, some of the nation’s largest wireless carriers don’t have a great track record in terms of protecting the sensitive information that you give them solely for the purposes of becoming a customer — let alone the information they collect about your use of their services after that point.

In January 2023, T-Mobile disclosed that someone stole data on 37 million customer accounts, including customer name, billing address, email, phone number, date of birth, T-Mobile account number and plan details. In August 2021, T-Mobile acknowledged that hackers made off with the names, dates of birth, Social Security numbers and driver’s license/ID information on more than 40 million current, former or prospective customers who applied for credit with the company.

Last summer, a cybercriminal began selling the names, email addresses, phone numbers, SSNs and dates of birth on 23 million Americans. An exhaustive analysis of the data strongly suggested it all belonged to customers of one AT&T company or another. AT&T stopped short of saying the data wasn’t theirs, but said the records did not appear to have come from its systems and may be tied to a previous data incident at another company.

However frequently the carriers may alert consumers about CPNI breaches, it’s probably nowhere near often enough. Currently, the carriers are required to report a consumer CPNI breach only in cases “when a person, without authorization or exceeding authorization, has intentionally gained access to, used or disclosed CPNI.”

But that definition of breach was crafted eons ago, back when the primary way CPNI was exposed was through “pretexting,” such when the phone company’s employees are tricked into giving away protected customer data.

In January, regulators at the U.S. Federal Communications Commission (FCC) proposed amending the definition of “breach” to include things like inadvertent disclosure — such as when companies expose CPNI data on a poorly-secured server in the cloud. The FCC is accepting public comments on the matter until March 24, 2023.

While it’s true that the leak of CPNI data does not involve sensitive information like Social Security or credit card numbers, one thing AT&T’s breach notice doesn’t mention is that CPNI data — such as balances and payments made — can be abused by fraudsters to make scam emails and text messages more believable when they’re trying to impersonate AT&T and phish AT&T customers.

The other problem with letting companies share or sell your CPNI data is that the wireless carriers can change their privacy policies at any time, and you are assumed to be okay with those changes as long as you keep using their services.

For example, location data from your wireless device is most definitely CPNI, and yet until very recently all of the major carriers sold their customers’ real-time location data to third party data brokers without customer consent.

What was their punishment? In 2020, the FCC proposed fines totaling $208 million against all of the major carriers for selling their customers’ real-time location data. If that sounds like a lot of money, consider that all of the major wireless providers reported tens of billions of dollars in revenue last year (e.g., Verizon’s consumer revenue alone was more than $100 billion last year).

If the United States had federal privacy laws that were at all consumer-friendly and relevant to today’s digital economy, this kind of data collection and sharing would always be opt-in by default. In such a world, the enormously profitable wireless industry would likely be forced to offer clear financial incentives to customers who choose to share this information.

But until that day arrives, understand that the carriers can change their data collection and sharing policies when it suits them. And regardless of whether you actually read any notices about changes to their privacy policies, you will have agreed to those changes as long as you continue using their service.
