Drilling Down on Uncle Sam’s Proposed TP-Link Ban

The U.S. government is reportedly preparing to ban the sale of wireless routers and other networking gear from TP-Link Systems, a tech company that currently enjoys an estimated 50% market share among home users and small businesses. Experts say while the proposed ban may have more to do with TP-Link’s ties to China than any specific technical threats, much of the rest of the industry serving this market also sources hardware from China and ships products that are insecure fresh out of the box.

The Washington Post recently reported that more than a half-dozen federal departments and agencies were backing a proposed ban on future sales of TP-Link devices in the United States. The story said U.S. Department of Commerce officials concluded TP-Link Systems products pose a risk because the U.S.-based company’s products handle sensitive American data and because the officials believe it remains subject to jurisdiction or influence by the Chinese government.

TP-Link Systems denies that, saying that it fully split from the Chinese TP-Link Technologies over the past three years, and that its critics have vastly overstated the company’s market share (TP-Link puts it at around 30 percent). TP-Link says it has headquarters in California, with a branch in Singapore, and that it manufactures in Vietnam. The company says it researches, designs, develops and manufactures everything except its chipsets in-house.

TP-Link Systems told The Post it has sole ownership of some engineering, design and manufacturing capabilities in China that were once part of China-based TP-Link Technologies, and that it operates them without Chinese government supervision.

“TP-Link vigorously disputes any allegation that its products present national security risks to the United States,” Ricca Silverio, a spokeswoman for TP-Link Systems, said in a statement. “TP-Link is a U.S. company committed to supplying high-quality and secure products to the U.S. market and beyond.”

Cost is a big reason TP-Link devices are so prevalent in the consumer and small business market: As this February 2025 story from Wired observed regarding the proposed ban, TP-Link has long had a reputation for flooding the market with devices that are considerably cheaper than comparable models from other vendors. That price point (and consistently excellent performance ratings) has made TP-Link a favorite among Internet service providers (ISPs) that provide routers to their customers.

In August 2024, the chairman and the ranking member of the House Select Committee on the Strategic Competition Between the United States and the Chinese Communist Party called for an investigation into TP-Link devices, which they said were found on U.S. military bases and for sale at exchanges that sell them to members of the military and their families.

“TP-Link’s unusual degree of vulnerabilities and required compliance with PRC law are in and of themselves disconcerting,” the House lawmakers warned in a letter (PDF) to the director of the Commerce Department. “When combined with the PRC government’s common use of SOHO [small office/home office] routers like TP-Link to perpetrate extensive cyberattacks in the United States, it becomes significantly alarming.”

The letter cited a May 2023 blog post by Check Point Research about a Chinese state-sponsored hacking group dubbed “Camaro Dragon” that used a malicious firmware implant for some TP-Link routers to carry out a sequence of targeted cyberattacks against European foreign affairs entities. Check Point said while it only found the malicious firmware on TP-Link devices, “the firmware-agnostic nature of the implanted components indicates that a wide range of devices and vendors may be at risk.”

In a report published in October 2024, Microsoft said it was tracking a network of compromised TP-Link small office and home office routers that has been abused by multiple distinct Chinese state-sponsored hacking groups since 2021. Microsoft found the hacker groups were leveraging the compromised TP-Link systems to conduct “password spraying” attacks against Microsoft accounts. Password spraying involves rapidly attempting to access a large number of accounts (usernames/email addresses) with a relatively small number of commonly used passwords.

TP-Link rightly points out that most of its competitors likewise source components from China. The company also correctly notes that advanced persistent threat (APT) groups from China and other nations have leveraged vulnerabilities in products from their competitors, such as Cisco and Netgear.

But that may be cold comfort for TP-Link customers who are now wondering if it’s smart to continue using these products, or whether it makes sense to buy more costly networking gear that might only be marginally less vulnerable to compromise.

Almost without exception, the hardware and software that ships with most consumer-grade routers includes a number of default settings that need to be changed before the devices can be safely connected to the Internet. For example, bring a new router online without changing the default username and password and chances are it will only take a few minutes before it is probed and possibly compromised by some type of Internet-of-Things botnet. Also, it is incredibly common for the firmware in a brand new router to be dangerously out of date by the time it is purchased and unboxed.

Until quite recently, the idea that router manufacturers should make it easier for their customers to use these products safely was something of an anathema to this industry. Consumers were largely left to figure that out on their own, with predictably disastrous results.

But over the past few years, many manufacturers of popular consumer routers have begun forcing users to perform basic hygiene — such as changing the default password and updating the internal firmware — before the devices can be used as a router. For example, most brands of “mesh” wireless routers — like Amazon’s Eero, Netgear’s Orbi series, or Asus’s ZenWifi — require online registration that automates these critical steps going forward (or at least through their stated support lifecycle).

For better or worse, less expensive, traditional consumer routers like those from Belkin and Linksys also now automate this setup by heavily steering customers toward installing a mobile app to complete the installation (this often comes as a shock to people more accustomed to manually configuring a router). Still, these products tend to put the onus on users to check for and install available updates periodically. Also, they’re often powered by underwhelming or else bloated firmware, and a dearth of configurable options.

Of course, not everyone wants to fiddle with mobile apps or is comfortable with registering their router so that it can be managed or monitored remotely in the cloud. For those hands-on folks — and for power users seeking more advanced router features like VPNs, ad blockers and network monitoring — the best advice is to check if your router’s stock firmware can be replaced with open-source alternatives, such as OpenWrt or DD-WRT.

These open-source firmware options are compatible with a wide range of devices, and they generally offer more features and configurability. Open-source firmware can even help extend the life of routers years after the vendor stops supporting the underlying hardware, but it still requires users to manually check for and install any available updates.

Happily, TP-Link users spooked by the proposed ban may have an alternative to outright junking these devices, as many TP-Link routers also support open-source firmware options like OpenWRT. While this approach may not eliminate any potential hardware-specific security flaws, it could serve as an effective hedge against more common vendor-specific vulnerabilities, such as undocumented user accounts, hard-coded credentials, and weaknesses that allow attackers to bypass authentication.

Regardless of the brand, if your router is more than four or five years old it may be worth upgrading for performance reasons alone — particularly if your home or office is primarily accessing the Internet through WiFi.

NB: The Post’s story notes that a substantial portion of TP-Link routers and those of its competitors are purchased or leased through ISPs. In these cases, the devices are typically managed and updated remotely by your ISP, and equipped with custom profiles responsible for authenticating your device to the ISP’s network. If this describes your setup, please do not attempt to modify or replace these devices without first consulting with your Internet provider.

Who’s Behind the Seized Forums ‘Cracked’ & ‘Nulled’?

The FBI joined authorities across Europe last week in seizing domain names for Cracked and Nulled, English-language cybercrime forums with millions of users that trafficked in stolen data, hacking tools and malware. An investigation into the history of these communities shows their apparent co-founders quite openly operate an Internet service provider and a pair of e-commerce platforms catering to buyers and sellers on both forums.

In this 2019 post from Cracked, a forum moderator told the author of the post (Buddie) that the owner of the RDP service was the founder of Nulled, a.k.a. “Finndev.” Image: Ke-la.com.

On Jan. 30, the U.S. Department of Justice said it seized eight domain names that were used to operate Cracked, a cybercrime forum that sprang up in 2018 and attracted more than four million users. The DOJ said the law enforcement action, dubbed Operation Talent, also seized domains tied to Sellix, Cracked’s payment processor.

In addition, the government seized the domain names for two popular anonymity services that were heavily advertised on Cracked and Nulled and allowed customers to rent virtual servers: StarkRDP[.]io, and rdp[.]sh.

Those archived webpages show both RDP services were owned by an entity called 1337 Services Gmbh. According to corporate records compiled by Northdata.com, 1337 Services GmbH is also known as AS210558 and is incorporated in Hamburg, Germany.

The Cracked forum administrator went by the nicknames “FlorainN” and “StarkRDP” on multiple cybercrime forums. Meanwhile, a LinkedIn profile for a Florian M. from Germany refers to this person as the co-founder of Sellix and founder of 1337 Services GmbH.

Northdata’s business profile for 1337 Services GmbH shows the company is controlled by two individuals: 32-year-old Florian Marzahl and Finn Alexander Grimpe, 28.

An organization chart showing the owners of 1337 Services GmbH as Florian Marzahl and Finn Grimpe. Image: Northdata.com.

Neither Marzahl nor Grimpe responded to requests for comment. But Grimpe’s first name is interesting because it corresponds to the nickname chosen by the founder of Nulled, who goes by the monikers “Finn” and “Finndev.” NorthData reveals that Grimpe was the founder of a German entity called DreamDrive GmbH, which rented out high-end sports cars and motorcycles.

According to the cyber intelligence firm Intel 471, a user named Finndev registered on multiple cybercrime forums, including Raidforums [seized by the FBI in 2022], Void[.]to, and vDOS, a DDoS-for-hire service that was shut down in 2016 after its founders were arrested.

The email address used for those accounts was f.grimpe@gmail.com. DomainTools.com reports f.grimpe@gmail.com was used to register at least nine domain names, including nulled[.]lol and nulled[.]it. Neither of these domains were among those seized in Operation Talent.

Intel471 finds the user FlorainN registered across multiple cybercrime forums using the email address olivia.messla@outlook.de. The breach tracking service Constella Intelligence says this email address used the same password (and slight variations of it) across many accounts online — including at hacker forums — and that the same password was used in connection with dozens of other email addresses, such as florianmarzahl@hotmail.de, and fmarzahl137@gmail.com.

The Justice Department said the Nulled marketplace had more than five million members, and has been selling stolen login credentials, stolen identification documents and hacking services, as well as tools for carrying out cybercrime and fraud, since 2016.

Perhaps fittingly, both Cracked and Nulled have been hacked over the years, exposing countless private messages between forum users. A review of those messages archived by Intel 471 showed that dozens of early forum members referred privately to Finndev as the owner of shoppy[.]gg, an e-commerce platform that caters to the same clientele as Sellix.

Shoppy was not targeted as part of Operation Talent, and its website remains online. Northdata reports that Shoppy’s business name — Shoppy Ecommerce Ltd. — is registered at an address in Gan-Ner, Israel, but there is no ownership information about this entity. Shoppy did not respond to requests for comment.

Constella found that a user named Shoppy registered on Cracked in 2019 using the email address finn@shoppy[.]gg. Constella says that email address is tied to a Twitter/X account for Shoppy Ecommerce in Israel.

The DOJ said one of the alleged administrators of Nulled, a 29-year-old Argentinian national named Lucas Sohn, was arrested in Spain. The government has not announced any other arrests or charges associated with Operation Talent.

Indeed, both StarkRDP and FloraiN have posted to their accounts on Telegram that there were no charges levied against the proprietors of 1337 Services GmbH. FlorainN told former customers they were in the process of moving to a new name and domain for StarkRDP, where existing accounts and balances would be transferred.

“StarkRDP has always been operating by the law and is not involved in any of these alleged crimes and the legal process will confirm this,” the StarkRDP Telegram account wrote on January 30. “All of your servers are safe and they have not been collected in this operation. The only things that were seized is the website server and our domain. Unfortunately, no one can tell who took it and with whom we can talk about it. Therefore, we will restart operation soon, under a different name, to close the chapter [of] ‘StarkRDP.'”

Infrastructure Laundering: Blending in with the Cloud

In an effort to blend in and make their malicious traffic tougher to block, hosting firms catering to cybercriminals in China and Russia increasingly are funneling their operations through major U.S. cloud providers. Research published this week on one such outfit — a sprawling network tied to Chinese organized crime gangs and aptly named “Funnull” — highlights a persistent whac-a-mole problem facing cloud services.

In October 2024, the security firm Silent Push published a lengthy analysis of how Amazon AWS and Microsoft Azure were providing services to Funnull, a two-year-old Chinese content delivery network that hosts a wide variety of fake trading apps, pig butchering scams, gambling websites, and retail phishing pages.

Funnull made headlines last summer after it acquired the domain name polyfill[.]io, previously the home of a widely-used open source code library that allowed older browsers to handle advanced functions that weren’t natively supported. There were still tens of thousands of legitimate domains linking to the Polyfill domain at the time of its acquisition, and Funnull soon after conducted a supply-chain attack that redirected visitors to malicious sites.

Silent Push’s October 2024 report found a vast number of domains hosted via Funnull promoting gambling sites that bear the logo of the Suncity Group, a Chinese entity named in a 2024 UN report (PDF) for laundering millions of dollars for the North Korean Lazarus Group.

In 2023, Suncity’s CEO was sentenced to 18 years in prison on charges of fraud, illegal gambling, and “triad offenses,” i.e. working with Chinese transnational organized crime syndicates. Suncity is alleged to have built an underground banking system that laundered billions of dollars for criminals.

It is likely the gambling sites coming through Funnull are abusing top casino brands as part of their money laundering schemes. In reporting on Silent Push’s October report, TechCrunch obtained a comment from Bwin, one of the casinos being advertised en masse through Funnull, and Bwin said those websites did not belong to them.

Gambling is illegal in China except in Macau, a special administrative region of China. Silent Push researchers say Funnull may be helping online gamblers in China evade the Communist party’s “Great Firewall,” which blocks access to gambling destinations.

Silent Push’s Zach Edwards said that upon revisiting Funnull’s infrastructure again this month, they found dozens of the same Amazon and Microsoft cloud Internet addresses still forwarding Funnull traffic through a dizzying chain of auto-generated domain names before redirecting malicious or phishous websites.

Edwards said Funnull is a textbook example of an increasing trend Silent Push calls “infrastructure laundering,” wherein crooks selling cybercrime services will relay some or all of their malicious traffic through U.S. cloud providers.

“It’s crucial for global hosting companies based in the West to wake up to the fact that extremely low quality and suspicious web hosts based out of China are deliberately renting IP space from multiple companies and then mapping those IPs to their criminal client websites,” Edwards told KrebsOnSecurity. “We need these major hosts to create internal policies so that if they are renting IP space to one entity, who further rents it to host numerous criminal websites, all of those IPs should be reclaimed and the CDN who purchased them should be banned from future IP rentals or purchases.”

Reached for comment, Amazon referred this reporter to a statement Silent Push included in a report released today. Amazon said AWS was already aware of the Funnull addresses tracked by Silent Push, and that it had suspended all known accounts linked to the activity.

Amazon said that contrary to implications in the Silent Push report, it has every reason to aggressively police its network against this activity, noting the accounts tied to Funnull used “fraudulent methods to temporarily acquire infrastructure, for which it never pays. Thus, AWS incurs damages as a result of the abusive activity.”

“When AWS’s automated or manual systems detect potential abuse, or when we receive reports of potential abuse, we act quickly to investigate and take action to stop any prohibited activity,” Amazon’s statement continues. “In the event anyone suspects that AWS resources are being used for abusive activity, we encourage them to report it to AWS Trust & Safety using the report abuse form. In this case, the authors of the report never notified AWS of the findings of their research via our easy-to-find security and abuse reporting channels. Instead, AWS first learned of their research from a journalist to whom the researchers had provided a draft.”

Microsoft likewise said it takes such abuse seriously, and encouraged others to report suspicious activity found on its network.

“We are committed to protecting our customers against this kind of activity and actively enforce acceptable use policies when violations are detected,” Microsoft said in a written statement. “We encourage reporting suspicious activity to Microsoft so we can investigate and take appropriate actions.”

Richard Hummel is threat intelligence lead at NETSCOUT. Hummel said it used to be that “noisy” and frequently disruptive malicious traffic — such as automated application layer attacks, and “brute force” efforts to crack passwords or find vulnerabilities in websites — came mostly from botnets, or large collections of hacked devices.

But he said the vast majority of the infrastructure used to funnel this type of traffic is now proxied through major cloud providers, which can make it difficult for organizations to block at the network level.

“From a defenders point of view, you can’t wholesale block cloud providers, because a single IP can host thousands or tens of thousands of domains,” Hummel said.

In May 2024, KrebsOnSecurity published a deep dive on Stark Industries Solutions, an ISP that materialized at the start of Russia’s invasion of Ukraine and has been used as a global proxy network that conceals the true source of cyberattacks and disinformation campaigns against enemies of Russia. Experts said much of the malicious traffic  traversing Stark’s network (e.g. vulnerability scanning and password brute force attacks) was being bounced through U.S.-based cloud providers.

Stark’s network has been a favorite of the Russian hacktivist group called NoName057(16), which frequently launches huge distributed denial-of-service (DDoS) attacks against a variety of targets seen as opposed to Moscow. Hummel said NoName’s history suggests they are adept at cycling through new cloud provider accounts, making anti-abuse efforts into a game of whac-a-mole.

“It almost doesn’t matter if the cloud provider is on point and takes it down because the bad guys will just spin up a new one,” he said. “Even if they’re only able to use it for an hour, they’ve already done their damage. It’s a really difficult problem.”

Edwards said Amazon declined to specify whether the banned Funnull users were operating using compromised accounts or stolen payment card data, or something else.

“I’m surprised they wanted to lean into ‘We’ve caught this 1,200+ times and have taken these down!’ and yet didn’t connect that each of those IPs was mapped to [the same] Chinese CDN,” he said. “We’re just thankful Amazon confirmed that account mules are being used for this and it isn’t some front-door relationship. We haven’t heard the same thing from Microsoft but it’s very likely that the same thing is happening.”

Funnull wasn’t always a bulletproof hosting network for scam sites. Prior to 2022, the network was known as Anjie CDN, based in the Philippines. One of Anjie’s properties was a website called funnull[.]app. Loading that domain reveals a pop-up message by the original Anjie CDN owner, who said their operations had been seized by an entity known as Fangneng CDN and ACB Group, the parent company of Funnull.

A machine-translated message from the former owner of Anjie CDN, a Chinese content delivery network that is now Funnull.

“After I got into trouble, the company was managed by my family,” the message explains. “Because my family was isolated and helpless, they were persuaded by villains to sell the company. Recently, many companies have contacted my family and threatened them, believing that Fangneng CDN used penetration and mirroring technology through customer domain names to steal member information and financial transactions, and stole customer programs by renting and selling servers. This matter has nothing to do with me and my family. Please contact Fangneng CDN to resolve it.”

In January 2024, the U.S. Department of Commerce issued a proposed rule that would require cloud providers to create a “Customer Identification Program” that includes procedures to collect data sufficient to determine whether each potential customer is a foreign or U.S. person.

According to the law firm Crowell & Moring LLP, the Commerce rule also would require “infrastructure as a service” (IaaS) providers to report knowledge of any transactions with foreign persons that might allow the foreign entity to train a large AI model with potential capabilities that could be used in malicious cyber-enabled activity.

“The proposed rulemaking has garnered global attention, as its cross-border data collection requirements are unprecedented in the cloud computing space,” Crowell wrote. “To the extent the U.S. alone imposes these requirements, there is concern that U.S. IaaS providers could face a competitive disadvantage, as U.S. allies have not yet announced similar foreign customer identification requirements.”

It remains unclear if the new White House administration will push forward with the requirements. The Commerce action was mandated as part of an executive order President Trump issued a day before leaving office in January 2021.

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.

Are Mobile Devices Less Secure than PCs?

Are smartphones less secure than PCs? The answer to that is, they’re different. They face different security threats. Yet they certainly share one thing in common — they both need protection.

So, what makes a smartphone unique when it comes to security? And how do you go about protecting it? We’ll cover both here.

Apps, spam texts, and other smartphone vulnerabilities

Several facts of life about smartphones set them apart when it comes to keeping your devices safer. A quick rundown looks like this:

First off, people keep lots of apps on their phones. Old ones, new ones, ones they practically forgot they had. The security issue that comes into play there is that any app on a phone is subject to vulnerabilities.

A vulnerability in just one of the dozens of apps on a phone can lead to problems. The adage of “the weakest link” applies here. The phone is only as secure as its least secure app. And that goes for the phone’s operating system as well.

Additionally, app permissions can also introduce risks. Apps often request access to different parts of your phone to work — such as when a messenger app asks for access to contacts and photos. In the case of malicious apps, they’ll ask for far more permissions than they need. A classic example involves the old “flashlight apps” that invasively asked for a wide swath of permissions. That gave the hackers all kinds of info on users, including things like location info. Today, the practice of malicious, permission-thirsty apps continues with wallpaper apps, utility apps, games, and more.

As for other malicious apps, sometimes people download them without knowing. This often happens when shopping in third-party app stores, yet it can happen in legit app stores as well — despite rigorous review processes from Apple and Google. Sometimes, hackers sneak them through the review process for approval. These apps might include spyware, ransomware, and other forms of malware.

Many people put their smartphones to personal and professional use.[i] That might mean the phone has access to corporate apps, networks, and data. If the phone gets compromised, those corporate assets might get compromised too. And it can work in the other direction. A corporate compromise might affect an employee’s smartphone.

More and more, our phones are our wallets. Digital wallets and payment apps have certainly gained popularity. They speed up checkout and make splitting meals with friends easy. That makes the prospect of a lost or stolen phone all the more serious. An unsecured phone in the hands of another is like forking over your wallet.

Lastly, spam texts. Unique to phones are the sketchy links that crop up in texting and messaging apps. These often lead to scam sites and other sites that spread malware.

With a good sense of what makes securing your smartphone unique, let’s look at several steps you can take to protect it.

How to protect your smartphone

  1. Update your phone’s apps and operating system

Keeping your phone’s apps and operating system up to date can greatly improve your security. Updates can fix vulnerabilities that hackers rely on to pull off their malware-based attacks. it’s another tried and true method of keeping yourself safer — and for keeping your phone running great too.

  1. Lock your phone

With all that you keep and conduct on your phone, a lock is a must. Whether you have a PIN, passcode, or facial recognition available, put it into play. The same goes for things like your payment, banking, and financial apps. Ensure you have them locked too.

  1. Avoid third-party app stores

As mentioned above, app stores have measures in place to review and vet apps that help ensure they’re safe and secure. Third-party sites might very well not, and they might intentionally host malicious apps as part of a front. Further, legitimate app stores are quick to remove malicious apps from their stores once discovered, making shopping there safer still.

  1. Review apps carefully

Check out the developer — have they published several other apps with many downloads and good reviews? A legit app typically has many reviews. In contrast, malicious apps might have only a handful of (phony) five-star reviews. Lastly, look for typos and poor grammar in both the app description and screenshots. They could be a sign that a hacker slapped the app together and quickly deployed it.

  1. Go with a strong recommendation.

Yet better than combing through user reviews yourself is getting a recommendation from a trusted source, like a well-known publication or app store editors themselves. In this case, much of the vetting work has been done for you by an established reviewer. A quick online search like “best fitness apps” or “best apps for travelers” should turn up articles from legitimate sites that can suggest good options and describe them in detail before you download.

  1. Keep an eye on app permissions

Another way hackers weasel their way into your device is by getting permissions to access things like your location, contacts, and photos — and they’ll use malicious apps to do it. If an app asks for way more than you bargained for, like a simple puzzle game that asks for access to your camera or microphone, it might be a scam. Delete the app.

  1. Learn how to remotely lock or erase your smartphone

So what happens if your phone ends up getting lost or stolen? A combination of device tracking, device locking, and remote erasing can help protect your phone and the data on it. Different device manufacturers have different ways of going about it, but the result is the same — you can prevent others from using your phone. You can even erase it if you’re truly worried that it’s gone for good. Apple provides iOS users with a step-by-step guide, and Google offers a guide for Android users as well.

  1. Protect your phone and block sketchy links

Comprehensive online protection software can secure your phone in the same ways that it secures your laptops and computers. Installing it can protect your privacy, and keep you safe from attacks on public Wi-Fi, just to name a few things it can do. Ours also includes Text Scam Detector that blocks sketchy links in texts, messages, and email before they do you any harm. And if you tap that link by mistake, Text Scam Detector still blocks it.

WordPress Plugin Exploited to Steal Credit Card Data from E-commerce Sites

Unknown threat actors are abusing lesser-known code snippet plugins for WordPress to insert malicious PHP code in victim sites that are capable of harvesting credit card data. The campaign, observed by Sucuri on May 11, 2024, entails the abuse of a WordPress plugin called Dessky Snippets, which allows users to add custom PHP code. It has over 200 active installations.

April’s Patch Tuesday Brings Record Number of Fixes

If only Patch Tuesdays came around infrequently — like total solar eclipse rare — instead of just creeping up on us each month like The Man in the Moon. Although to be fair, it would be tough for Microsoft to eclipse the number of vulnerabilities fixed in this month’s patch batch — a record 147 flaws in Windows and related software.

Yes, you read that right. Microsoft today released updates to address 147 security holes in Windows, Office, Azure, .NET Framework, Visual Studio, SQL Server, DNS Server, Windows Defender, Bitlocker, and Windows Secure Boot.

“This is the largest release from Microsoft this year and the largest since at least 2017,” said Dustin Childs, from Trend Micro’s Zero Day Initiative (ZDI). “As far as I can tell, it’s the largest Patch Tuesday release from Microsoft of all time.”

Tempering the sheer volume of this month’s patches is the middling severity of many of the bugs. Only three of April’s vulnerabilities earned Microsoft’s most-dire “critical” rating, meaning they can be abused by malware or malcontents to take remote control over unpatched systems with no help from users.

Most of the flaws that Microsoft deems “more likely to be exploited” this month are marked as “important,” which usually involve bugs that require a bit more user interaction (social engineering) but which nevertheless can result in system security bypass, compromise, and the theft of critical assets.

Ben McCarthy, lead cyber security engineer at Immersive Labs called attention to CVE-2024-20670, an Outlook for Windows spoofing vulnerability described as being easy to exploit. It involves convincing a user to click on a malicious link in an email, which can then steal the user’s password hash and authenticate as the user in another Microsoft service.

Another interesting bug McCarthy pointed to is CVE-2024-29063, which involves hard-coded credentials in Azure’s search backend infrastructure that could be gleaned by taking advantage of Azure AI search.

“This along with many other AI attacks in recent news shows a potential new attack surface that we are just learning how to mitigate against,” McCarthy said. “Microsoft has updated their backend and notified any customers who have been affected by the credential leakage.”

CVE-2024-29988 is a weakness that allows attackers to bypass Windows SmartScreen, a technology Microsoft designed to provide additional protections for end users against phishing and malware attacks. Childs said one of ZDI’s researchers found this vulnerability being exploited in the wild, although Microsoft doesn’t currently list CVE-2024-29988 as being exploited.

“I would treat this as in the wild until Microsoft clarifies,” Childs said. “The bug itself acts much like CVE-2024-21412 – a [zero-day threat from February] that bypassed the Mark of the Web feature and allows malware to execute on a target system. Threat actors are sending exploits in a zipped file to evade EDR/NDR detection and then using this bug (and others) to bypass Mark of the Web.”

Update, 7:46 p.m. ET: A previous version of this story said there were no zero-day vulnerabilities fixed this month. BleepingComputer reports that Microsoft has since confirmed that there are actually two zero-days. One is the flaw Childs just mentioned (CVE-2024-21412), and the other is CVE-2024-26234, described as a “proxy driver spoofing” weakness.

Satnam Narang at Tenable notes that this month’s release includes fixes for two dozen flaws in Windows Secure Boot, the majority of which are considered “Exploitation Less Likely” according to Microsoft.

“However, the last time Microsoft patched a flaw in Windows Secure Boot in May 2023 had a notable impact as it was exploited in the wild and linked to the BlackLotus UEFI bootkit, which was sold on dark web forums for $5,000,” Narang said. “BlackLotus can bypass functionality called secure boot, which is designed to block malware from being able to load when booting up. While none of these Secure Boot vulnerabilities addressed this month were exploited in the wild, they serve as a reminder that flaws in Secure Boot persist, and we could see more malicious activity related to Secure Boot in the future.”

Adobe today released nine patches tackling at least two dozen vulnerabilities in a range of software products, including Adobe After Effects, Photoshop, Commerce, InDesign, Experience Manager, Media Encoder, Bridge, Illustrator, and Adobe Animate.

KrebsOnSecurity needs to correct the record on a point mentioned at the end of March’s “Fat Patch Tuesday” post, which looked at new AI capabilities built into Adobe Acrobat that are turned on by default. Adobe has since clarified that its apps won’t use AI to auto-scan your documents, as the original language in its FAQ suggested.

“In practice, no document scanning or analysis occurs unless a user actively engages with the AI features by agreeing to the terms, opening a document, and selecting the AI Assistant or generative summary buttons for that specific document,” Adobe said earlier this month.
