Just a few years ago when the topic of supporting offsite workers arose, some of the key conversation topics were related to purchase, logistics, deployment, maintenance and similar issues. The discussions back then were more like “special cases” vs. today’s environment where supporting workers offsite (now known as the hybrid workforce) has become a critical mainstream topic.
Now with the bulk of many organization’s workers off-premise, the topic of security and the ability of a security vendor to help support an organization’s hybrid workers has risen to the top of the selection criteria. In a soon to be released Cisco endpoint survey, it’s not surprising that the ability of a security vendor to make supporting the hybrid workforce easier and more efficient was the key motivating factor when organizations choose security solutions.
Today, when prospects and existing customers look at Cisco’s ability to support hybrid workers with our advanced security solution set and open platform, it’s quite clear that we can deliver on that promise. But, yes, good tools make it easier and more efficient, but the reality is that running a SOC or any security group, large or small, still takes a lot of work. Most organizations not only rely on advanced security tools but utilize a set of best practices to provide clarity of roles, efficiency of operation, and for the more prepared, have tested these best practices to prove to themselves that they are prepared for what’s next.
Knowing that not all organizations have this degree of security maturity and preparedness, we gathered a couple of subject matter experts together to discuss 5 areas of time-tested best practices that, besides the advanced tools offered by Cisco and others, can help your SOC (or small security team) yield actionable insights and guide you faster, and with more confidence, toward the outcomes you want.
In this webinar you will hear practical advice from Cisco technical marketing and a representative from our award winning Talos Threat Intelligence group, the same group who have created and are maintaining breach defense in partnership with Fortune 500 Security Operating Centers (SOC) around the globe.
You can expect to hear our 5 Best Practices recommendations on the following topics;

Today we’re examining some of the revelations in the Q3 Cisco Talos Incident Response Trends Report. This document is an anonymized look at of all the engagements that the Cisco Talos Incident Response team have been involved in over the previous three months. It also features threat intelligence from our team of researchers and analysts.
To start, take a watch of this episode of ThreatWise TV which explores how these trends have evolved since the previous quarter. Our guests also talk about incidents and cyber-attacks that they themselves have consulted on recently, including a particularly interesting insider threat case.
Ransomware returned as the top threat this quarter, after commodity trojans narrowly surpassed ransomware last quarter. Ransomware made up nearly 18 percent of all threats observed, up from 15 percent last quarter. Cisco Talos Incident Response (CTIR) observed high-profile families, such as Vice Society and Hive, as well as the newer family Blast Basta, which first emerged in April of this year.
Also noteworthy is the fact that CTIR saw an equal number in ransomware and pre- ransomware engagements this quarter, totalling nearly 40 percent of threats observed. Pre-ransomware is when we have observed a ransomware attack is about to happen, but the encryption of files has not yet taken place.
Pre-ransomware comprised 18 percent of threats this quarter, up from less than 5 percent previously. While it’s difficult to determine an adversary’s motivations if encryption does not take place, several behavioral characteristics bolster Talos’ confidence that ransomware may likely be the final objective. In these engagements adversaries were observed deploying frameworks such as Cobalt Strike and Mimikatz, alongside numerous enumeration and discovery techniques.
Commodity malware, such as the Qakbot banking trojan, was observed in multiple engagements this quarter. In one engagement, several compromised endpoints were seen communicating with IP addresses associated with Qakbot C2 traffic. This activity coincides with a general resurgence of Qakbot and its delivery of emerging ransomware families and offensive security frameworks that we have not previously observed Qakbot deploy. This comes at a time where competing email-based botnets like Emotet and Trickbot have suffered continued setbacks from law enforcement and tech companies.
Other threats this quarter include infostealers like Redline Stealer and Raccoon Stealer. Redline Stealer was observed across three engagements this quarter, two of which involved ransomware. The malware operators behind Raccoon introduced new functionality to the malware at the end of June, which likely contributed to its increased presence in engagements this quarter.
As infostealers have continued to rank highly in CTIR engagements, let’s explore them in a bit more detail.
Throughout the incidents discussed over the last few quarters, and CTIR engagements in general, information stealing plays a big part of the attackers’ TTPs.
From a high level, infostealers can be used to gain access a variety of sensitive information, such as contact information, financial details, and even intellectual property. The adversaries involved often proceed to exfiltrate this information and may then attempt to sell it in dark web forums, threaten to release it if a ransom isn’t paid, among other things.
While these instances can and do crop up in CTIR engagements, many of the infostealers seen in this space are used for accessing and collecting user credentials. Once an attacker has gained an initial foothold on a system, there are many places within an operating system that they can look for and collect credentials through the practice of credential dumping.
These stolen credentials may be offered up for sale on the dark web, alongside the stolen information mentioned above, but they can also prove to be a key weapon in an attacker’s arsenal. Their usefulness lies in one simple concept—why force your way into a system when you can just log in?
There are several advantages for bad actors that use this approach. Probably the most oblivious of these is that using pre-existing credentials is far more likely to go unnoticed than other more flagrant tactics an attacker can use. If part of the goal of an attack is to remain under the radar, activities carried out by “known users” are less likely to trigger security alerts when compared to tactics such as exploiting vulnerabilities or downloading malware binaries.
Adversaries tend to seek credentials with higher privileges, allowing them further control over the systems they compromise, with those including administrative access being the crown jewels.
User credentials can not only provide an attacker with means to elevate privileges and establish persistence on a system, but also to move laterally through a network. Some credentials, especially those with administrative privileges, can offer access to multiple systems throughout a network. By obtaining them, many more options become available to further an attack.
There are several threats involved in information stealing that appear repeatedly in CTIR engagements over the last few quarters.
Perhaps the most notorious is Mimikatz—a tool used to pull credentials from operating systems. Mimikatz is not malware per-se and can be useful for penetration testing and red team activities. But bad actors leverage it as well, and over the last few quarters CTIR has observed it being used in ransomware-as-a-service attacks, as well as pre-ransomware incidents.
CTIR has also observed Redline Stealer being utilized by adversaries in CTIR engagements across quarters. This infostealer has grown in popularity as a supplementary tool used alongside other malware. On more than one occasion, CTIR has identified stolen credentials on the dark web that claimed to have been obtained via Redline Stealer.
Other information stealers seen across the last few quarters include the Vidar information stealer, Raccoon Stealer, and SolarMaker, all of which have been used to further an adversary’s attacks.
Over the last several months, Talos has seen an increasing number of engagements involving insider threats. In one engagement this quarter, passwords were reset through a management console of a perimeter firewall that a disgruntled employee had access to.
The organization’s team changed all associated passwords but overlooked one administrative account. On the following day, someone logged in using that account, deleted all other accounts and firewall rules, and created one local account, likely to provide persistence.
You’ll hear Alexis Merritt, Incident Response Consultant for Cisco Talos, talk about this more in the ThreatWise TV episode.
To help protect against this threat when an individual leaves an organization, steps like disabling accounts and ensuring that connections to the enterprise remotely through VPN has been removed can be very valuable. Implementing a mechanism to wipe systems, especially for remote employees, is important as well.
For more on this topic, Cisco Secure recently put together a white paper on the Insider Threat Maturity FrameWork.
In several incidents over the last few quarters that involved information stealers, multi-factor authentication (MFA) was not properly implemented by the organizations impacted, providing adversaries an opportunity to infiltrate the networks. MFA tools like Cisco Secure Access by Duo can prevent attackers from successfully gaining access.
And finally, Cisco Advisory CISO Wolfgang Goerlich has created this storytelling video, to help people think about incident response in a new way:

A new ransomware threat is currently sweeping its way across home computers. And what’s making it extra tricky is that it’s disguised as an operating system update.
Be on the lookout for this new ransomware scheme and protect yourself from ransomware with a few of these tips.
Magniber is a new type of ransomware that is disguised at almost every touchpoint until it seemingly pops out of nowhere demanding money. The attack begins when someone visits a fake Windows 10 update website owned by the Magniber cybercriminal group. Once someone clicks on a malicious link on that site, file-encrypting malware downloads onto the device.
Another stealth maneuver of Magniber is that the encryption malware downloads as a JavaScript file straight to the memory of the device, which can often slide under an antivirus’ radar. This malware allows the criminal to view, delete, and encrypt files and gain administrator access of the device. Usually, before the person even knows their device is in danger, Magniber reveals itself and demands a ransom payment in exchange for releasing the documents and giving back control of the computer. If the device owner refuses to pay, the criminal threatens to delete the files forever.1
For the last several years, large companies fell left and right to breaches. Hacker groups infiltrated complex cybersecurity defenses, got ahold of sensitive company or customer information, and threatened to release their findings on the dark web if not paid a hefty ransom. The reasons cybercriminals targeted corporate databases versus personal devices wasn’t just because they could demand multiple millions, but because companies were better equipped to make ransom transactions anonymously. Often, cryptocurrency transactions are untraceable, which allows criminals to remain at large.
Now that more everyday people are proficient in cryptocurrency, ransomware may shift to targeting personal devices. Though the ransom payments won’t be as lucrative, there also won’t be corporate cybersecurity experts hot on the cybercriminal’s tail.
To avoid ransomware schemes similar to Magniber, adopt these three habits to better protect your device and digital privacy:
If a cybercriminal gets in touch with you and demands a ransom, immediately contact your local FBI field office and file a report with the FBI’s Internet Criminal Complaint Center. From there, the authorities will advise you on how to proceed.
Something you can start with now to defend against ransomware is to invest in McAfee+ Ultimate. It provides the most thorough device, privacy, and identity protection, including $25,000 in ransomware coverage.

Ransomware is one of the most dangerous threats organizations face today, so it’s no wonder that Cisco Talos Incident Response named it the top threat of the year in 2021. These attacks continue to grow and become more advanced, with ransomware attacks growing by 13% over 2021 and a whopping 79% over 2020 so far this year (see Figure 1 below).1 Stopping ransomware attacks isn’t easy either, as adversaries continue to change their techniques and attacks become increasingly sophisticated.
Fortunately, Cisco Secure Endpoint defends your organization from ransomware by delivering security outcomes that enable you to radically simplify your security, maximize your security operations, and achieve peace of mind. Let’s dive deeper into each of these areas to better understand how Secure Endpoint can help your organization defend against ransomware attacks.
Cybersecurity has become increasingly complex due to the numerous security solutions deployed by organizations today. These disparate point-products increase complexity while creating security gaps because they require additional management overhead and typically don’t communicate with each other. This increases the burden on security operations teams since they must spend time managing these different solutions and filling in the gaps between tools rather than using their time to investigate and respond to threats
Cisco takes a very different approach to cybersecurity by looking at ransomware endpoint protection holistically, as part of an integrated security solution. For instance, Secure Endpoint includes built-in extended detection and response (XDR) capabilities from the Cisco SecureX platform that centralizes visibility in a single console, creates high-fidelity detections by correlating threats, and coordinates threat response across your entire security environment. In addition, Secure Endpoint unifies your security stack, simplifies management, and reduces agent fatigue because we’ve consolidated endpoint protection, cloud security, and remote access agents into a single agent.
Learn more about how Secure Endpoint helps you simplify your security while defending your organization from ransomware attacks by watching this video:
One of the common themes we’ve heard from our customers is that their security operations teams are frequently overstretched. The ongoing cybersecurity skills shortage means that security teams have to do more with less and a vast number of security tools to manage along with inefficient security operations processes, often leading to burned-out security teams.
Cisco addresses these challenges by allowing you to get the most out of your security operations. For example, you can accelerate investigation and incident response with valuable vulnerability context since we’ve integrated risk-based vulnerability management from Kenna Security into Secure Endpoint. Moreover, Secure Endpoint includes advanced endpoint detection and response (EDR) capabilities via Orbital Advanced Search and built-in XDR from SecureX that enable you to rapidly detect, respond to, and contain ransomware attacks. Lastly, you can get the security expertise you need with proactive threat hunting from SecureX Threat Hunting, which uses an analyst-centric process to quickly spot hidden ransomware.
Check out how Secure Endpoint helps you maximize your security operations while defending your organization from ransomware attacks by watching this video:
Keeping up with the latest ransomware attacks can seem like an impossible challenge due to Ransomware-as-a-service (RaaS) kits which make it simple and lucrative to target organizations with ransomware and the evolving threat landscape, where attackers are continuously changing their methods to evade detection.
Cisco helps you stay ahead of the newest ransomware attacks and gives you the peace of mind you deserve by taking a comprehensive approach to ransomware endpoint protection. This means ensuring that you never have to go it alone with always-on security operations from Cisco Secure Endpoint Pro, a managed service that uses a team of Cisco security experts to perform the heavy lifting of securing your endpoints. It also includes offering advanced EDR and integrated XDR capabilities such as Orbital and SecureX to speed detection and response, simplify investigations, and quickly contain ransomware attacks before it’s too late. Finally, Secure Endpoint prevents initial ransomware infections with multifaceted prevention techniques such as machine learning, exploit prevention, and behavioral protection as well as actionable threat intelligence from the Cisco Talos research team.

Our all-new ransomware coverage is now available, ready to help just in case—all backed by expert advice to help you find the quickest and best possible path to recovery.
Ransomware coverage from McAfee can reimburse you up to $25,000 for losses resulting from a ransomware threat, including financial losses and ransom fees. You’ll find this ransomware coverage included with our McAfee+ Ultimate plan.
As well as eligibility for ransomware reimbursement, our team of experts can help you:
However, it’s important to realize that ransomware is unlike any other attack. When ransomware locks someone out of their device or encrypts their data and files so they can’t use them, a demand is usually made for money. Sometimes, paying the ransom results in the device being made accessible again or the files being decrypted. Yet like any ransom case, this result is not always guaranteed. There are plenty of cases where people pay the ransom but never get their data or access to their devices back.
Again, our coverage includes guidance from our expert advisers to help walk you through your options should the worst happen to you. You won’t be in it alone—particularly as you look to recover from what can be a complicated attack.
As the name implies, ransomware is a type of malware that holds your device or information for ransom. It may lock your computer or smartphone entirely or it may you out of your files by encrypting them so that you can’t access them. Whether it’s a hacker or a cybercrime organization behind the attack, the bad actor involved holds the key to unlock those files—and promises to do so. For a price. And as mentioned above, sometimes that doesn’t happen, even if you pay.
Ransomware can infect your devices several different ways:
Ransomware has seen quite the evolution over the years. Its origins date back to the late 1980s, where malware-loaded floppy disks were sent to users who installed them under false pretenses. There the malware would lie in wait until the user rebooted their computer for the 90th time and presented with a digital ransom note.
From there, ransomware attacks on individuals became more sophisticated, and more lucrative, with the advent of the internet and the millions of everyday users who flocked to it. Using phishing emails, malware downloads from phony sites, and compromised software and networks, hackers rapidly expanded their ransomware reach.
However, yet more lucrative for hackers and organized cybercriminals were public and private organizations. Shifting their attacks to so-called “big game” targets, hackers and organized cybercriminals have used ransomware to extort money from hospitals, city governments, financial institutions, and key energy infrastructure companies, to name just a few. Seeing further opportunity, ransomware attackers then began targeting smaller and mid-sized businesses as well. While the ransom demands account for lower amounts, these organizations often lack dedicated cybersecurity teams and the protections that come along with them, making these organizations easier to victimize.
Meanwhile, the body of malicious code and attack packages used to launch ransomware attacks has only grown. As a result, small-time hackers and hacking groups can find the tools they need to conduct an attack for sale or for lease as a service (Ransomware as a Service, or RaaS). In effect, these bad actors can simply access a dark web marketplace and figuratively pull a ready-to-deploy attack off the shelf.
As a result, ransomware remains a concern for individuals, even as businesses and governmental bodies of all sizes deal with its threat.
What makes ransomware so damaging is just how much effort it can take to undo. Setting aside the sophisticated attacks on businesses and governments for a moment, even those “off-the-shelf” attacks that some hackers will launch against individuals go beyond the average user’s ability to undo. For example, there are some known attacks with known methods of decrypting the data, however, that requires knowing specifically which attack was used. Attempting to undo the encryption with the wrong solution can potentially encrypt that data even more.
So without question, the best defense against ransomware is prevention. Comprehensive online protection software gives you the tools you need to help avoid becoming a ransomware victim. A few include:
Moreover, you can protect yourself further by backing up your files and data. A cloud storage solution,121cwdv 1765ujb n4yh that’s secured with a strong and unique password, offers one path. Likewise, you can back up your files on an external disk or drive, making sure to keep it disconnected from your network and stored in a safe place.
Also as mentioned in the bullets above, keep your operating system and apps current with the latest updates. Beyond making improvements in your operating system and apps, updates often also address security issues that hackers often use to compromise devices and apps.
Lastly, stay alert. Keep an eye out for sketchy links, attachments, websites, and messages. Bad actors will pull all kinds of phishing tricks to lure you their way, places where they try to compromise you, your devices, and data.
Taken together, the combination of online protection software and a few preventative steps can greatly reduce the chance that you’ll fall victim to ransomware. From there, you also have the assurance of our ransomware coverage, ready to get on the path to recovery, just in case.

Safety has a feeling all its own, and that’s what’s at the heart of McAfee+.
We created McAfee+ so people can not only be safe but feel safe online, particularly in a time when there’s so much concern about identity theft and invasion of our online privacy.
And those concerns have merit. Last year, reported cases of identity theft and fraud in the U.S. shot up to 5.7 million, to the tune of $5.8 billion in losses, a 70% increase over the year prior. Meanwhile, online data brokers continue to buy and sell highly detailed personal profiles with the data cobbled together from websites, apps, smartphones, connected appliances, and more, all as part of a global data-gathering economy estimated at well over $200 billion a year.
Yet despite growing awareness of the ways personal information is collected, bought, sold, and even stolen, it remains a somewhat invisible problem. You simply don’t see it as it happens, let alone know who’s collecting what information about you and toward what ends—whether legal, illegal, or somewhere in between. A recent study we conducted showed that 74% of consumers are concerned about keeping their personal information private online. Yet, most of us have found out the hard way (when we search for our name on the internet) that there is a lot of information about us that has been made public. It is our belief that every individual should have the right to be private, yet we know too many individuals don’t know where to begin. It is this very worry that made us focus our new product line on empowering our users to take charge of their privacy and identity online.
McAfee+ gives you that control.
Now available in the U.S., McAfee+ provides all-in-one online protection for your identity, privacy, and security. With McAfee+, you’ll feel safer online because you’ll have the tools, guidance and support to take the steps to be safer online. Here’s how:
You can see the entire range of features that cover your identity, privacy, and security with a visit to our McAfee+ page.
McAfee+ Ultimate offers our most thorough protection, with which you can lock your credit with a click or put a comprehensive security freeze in place, both to thwart potential identity theft. You can keep tabs on your credit with daily credit monitoring and get an alert when there’s credit activity to spot any irregularities quickly.
You’ll also feel like someone has your back. Even with the most thorough measures in place, identity theft and ransomware attacks can still strike, which can throw your personal and financial life into a tailspin. What do you do? Where do you start? Here, we have you covered. We offer two kinds of coverage that can help you recover your time, money, and good name:
Starting today, customers in the U.S. can purchase McAfee+ online at McAfee.com in Premium, Advanced, and Ultimate plans, in addition to individual and family subscriptions. McAfee+ will also be available online in the U.K., Canada, and Australia in the coming weeks with additional regions coming in the months ahead (features may vary by region).
We are very excited about bringing these new protections to you and we hope you will be too.

Coronavirus has caused a major shift to our working patterns. In many cases these will long outlast the pandemic. But working from home has its own risks. One is that you may invite ransomware attacks from a new breed of cyber-criminal who has previously confined his efforts to directly targeting the corporate network. Why? Because as a remote worker, you’re increasingly viewed as a soft target—the open doorway to extorting money from your employer.
So how does ransomware land up on your front doorstep? And what can a home worker do to shut that door?
The new ransomware trends
Last year, Trend Micro detected over 61 million ransomware-related threats, a 10% increase from 2018 figures. But things have only gotten worse from there. There has been a 20% spike in ransomware detections globally in the first half of 2020, rising to 109% in the US. And why is that?
At a basic level, ransomware searches for and encrypts most of the files on a targeted computer, so as to make them unusable. Victims are then asked to pay a ransom within a set time frame in order to receive the decryption key they need to unlock their data. If they don’t, and they haven’t backed-up this data, it could be lost forever.
The trend of late, however, has been to focus on public and private sector organizations whose staff are working from home (WFH). The rationale is that remote workers are less likely to be able to defend themselves from ransomware attacks, while they also provide a useful stepping-stone into high-value corporate networks. Moreover, cybercriminals are increasingly looking to steal sensitive data before they encrypt it, even as they’re more likely to fetch a higher ransom for their efforts than they do from a typical consumer, especially if the remote employee’s data is covered by cyber-insurance.
Home workers are also being more targeted for a number of reasons:
|
|
What’s the attack profile of the remote working threat?
In short, the bad guys are now looking to gain entry to the corporate network you may be accessing from home via a VPN, or to the cloud-hosted systems you use for work or sharing files, in order to first steal and then encrypt company data with ransomware as far and wide as possible into your organization. But the methods are familiar. They’ll

How can I prevent ransomware when working from home?
The good news is that you, the remote worker, can take some relatively straightforward steps up front to help mitigate the cascading risks to your company posed by the new ransomware. Try the following:

With these tools, you, the remote worker, can help shut the front door to ransomware, protecting your work, devices, and company from data theft and encryption for ransom.

When we published our 2020 Predictions report in December, we didn’t realize there was a global pandemic brewing that would give cybercriminals an almost daily news cycle to take advantage of in their attacks against people and organizations around the world. Malicious actors have always taken advantage of big news to use as lures for socially engineered threats, but these events tend to be fairly short news cycles.
When Covid-19 started making headlines in early 2020, we started seeing new threats using this in the attacks. As you see below, April was the peak month for email-based Covid-19 related threats.
The same was true for phishing URLs related to Covid-19, but for files using Covid-19 in their naming convention, the peak month in the first half was June.
Impact on Cybercrime
The constant 24×7 news around cases, cures and vaccines makes this pandemic unique for cybercriminals. Also, the shift to remote working and the challenges posed to supply chains all gave cybercriminals new content they could use as lures to entice victims into infecting themselves.
As we’ve seen for many years now, email-based threats were the most used threat vector by malicious actors, which makes sense as the number one infection vector to penetrate an organization’s network is to use a socially engineered email against an employee.
We even saw malicious mobile apps being developed using Covid-19 as a lure, as you see below.
In this case it was supporting potential cures for the virus, which many people would have wanted.
Other Highlights in 1H 2020
While Covid-19 dominated the threat landscape in the 1H 2020, it wasn’t the only thing that defined it. Ransomware actors continued their attacks against organizations, but as we’ve been seeing over the past year, they’ve become much more selective in their victims. The spray and pray model using spam has been shifted to a more targeted approach, similar to how nation-state actors and APT groups perform their attacks. Two things showcase this trend:
|
|
Home network attacks are another interesting aspect of the threat landscape in the first half of this year. We have millions of home routers around the world that give us threat data on events coming into and out of home networks.
Threat actors are taking advantage of more remote workers by launching more attacks against these home networks. As you see below, the first half of 2020 saw a marked increase in attacks.
Many of these attacks are brute force login attempts as actors try to obtain login credentials for routers and devices within the home network, which can allow them to do further damage.
The above are only a small number of security events and trends we saw in just six months of 2020. Our full roundup of the security landscape so far this year is detailed out in our security roundup report – Securing the Pandemic-Disrupted Workplace. You can read about all we found to help prepare for many of the threats we will continue to see for the rest of the year.

Trend Micro Research has developed a go-to resource for all things related to cybercriminal underground hosting and infrastructure. Today we released the second in this three-part series of reports which detail the what, how, and why of cybercriminal hosting (see the first part here).
As part of this report, we dive into the common life cycle of a compromised server from initial compromise to the different stages of monetization preferred by criminals. It’s also important to note that regardless of whether a company’s server is on-premise or cloud-based, criminals don’t care what kind of server they compromise.
To a criminal, any server that is exposed or vulnerable is fair game.
Cloud vs. On-Premise Servers
Cybercriminals don’t care where servers are located. They can leverage the storage space, computation resources, or steal data no matter what type of server they access. Whatever is most exposed will most likely be abused.
As digital transformation continues and potentially picks up to allow for continued remote working, cloud servers are more likely to be exposed. Many enterprise IT teams, unfortunately, are not arranged to provide the same protection for cloud as on-premise servers.
As a side note, we want to emphasize that this scenario applies only to cloud instances replicating the storage or processing power of an on-premise server. Containers or serverless functions won’t fall victim to this same type of compromise. Additionally, if the attacker compromises the cloud account, as opposed to a single running instance, then there is an entirely different attack life cycle as they can spin up computing resources at will. Although this is possible, however, it is not our focus here.
Attack Red Flags
Many IT and security teams might not look for earlier stages of abuse. Before getting hit by ransomware, however, there are other red flags that could alert teams to the breach.
If a server is compromised and used for cryptocurrency mining (also known as cryptomining), this can be one of the biggest red flags for a security team. The discovery of cryptomining malware running on any server should result in the company taking immediate action and initiating an incident response to lock down that server.
This indicator of compromise (IOC) is significant because while cryptomining malware is often seen as less serious compared to other malware types, it is also used as a monetization tactic that can run in the background while server access is being sold for further malicious activity. For example, access could be sold for use as a server for underground hosting. Meanwhile, the data could be exfiltrated and sold as personally identifiable information (PII) or for industrial espionage, or it could be sold for a targeted ransomware attack. It’s possible to think of the presence of cryptomining malware as the proverbial canary in a coal mine: This is the case, at least, for several access-as-a-service (AaaS) criminals who use this as part of their business model.
Attack Life Cycle
Attacks on compromised servers follow a common path:
|
|
The monetization lifecycle of a compromised server
Often, targeted ransomware is the final stage. In most cases, asset categorization reveals data that is valuable to the business but not necessarily valuable for espionage.
A deep understanding of the servers and network allows criminals behind a targeted ransomware attack to hit the company where it hurts the most. These criminals would know the dataset, where they live, whether there are backups of the data, and more. With such a detailed blueprint of the organization in their hands, cybercriminals can lock down critical systems and demand higher ransom, as we saw in our 2020 midyear security roundup report.
In addition, while a ransomware attack would be the visible urgent issue for the defender to solve in such an incident, the same attack could also indicate that something far more serious has likely already taken place: the theft of company data, which should be factored into the company’s response planning. More importantly, it should be noted that once a company finds an IOC for cryptocurrency, stopping the attacker right then and there could save them considerable time and money in the future.
Ultimately, no matter where a company’s data is stored, hybrid cloud security is critical to preventing this life cycle.

Ransomware is Still a Blight on Business
Trends come and go with alarming regularity in cybersecurity. Yet a persistent menace over the past few years has been ransomware. Now mainly targeting organizations rather than consumers, and with increasingly sophisticated tools and tactics at their disposal, the cybercriminals behind these campaigns have been turning up the heat during the COVID-19 pandemic. That’s why we need industry partnerships like No More Ransom.
Celebrating its fourth anniversary this week, the initiative has helped over four million victims fight the scourge of ransomware, saving hundreds of millions of dollars in the process. At Trend Micro, we’re proud to have played a major part, helping to decrypt over 77 million files for victims.
Not going anywhere
Ransomware has been with us for years, but only really hit the mainstream after the global WannaCry and NotPetya incidents of 2017. Unfortunately, that was just the start. Today, no sector is safe. We saw attacks rage across US municipalities, school districts and hospitals in 2019. Most recently, a major outage at a connected technology giant impacted everything from consumer fitness trackers to on-board flight systems.
Such attacks can hit victim organizations hard. There are serious reputational and financial repercussions from major service outages, and the stakes have been raised even further as attackers now often steal data before encrypting victims’ files. A recent incident at a US cloud computing provider has led to data compromise at over 20 universities and charities in the UK and North America, for example. A separate ransomware attack on a managed service provider earlier this year may cost it up to $70m.
The bad guys have shown no sign of slowing down during the pandemic — quite the reverse. Even as hospitals have been battling to save the lives of patients battling COVID-19, they’ve been targeted by ransomware designed to lock mission-critical systems.
No More Ransom
That’s why we need to celebrate public-private partnerships like No More Ransom, which provides helpful advice for victims and a free decryption tool repository. Over the past four years it has helped 4.2 million visitors from 188 countries, preventing an estimated $632 million in ransom demands finding its way into the pockets of cyber-criminals.
At Trend Micro, we’re proud to have been an associate partner from the very start, contributing our own decryption tools to the scores available today to unlock 140 separate ransomware types. Since the start of No More Ransom, Trend Micro tools have been downloaded nearly half a million times, helping over 50,000 victims globally to decrypt more than 77 million files. We simply can’t put a price on this kind of intervention.

Tax season has always been a pretty nerve-wracking time for hard-working Americans. But over the years, technology advances have arrived to gradually make the process a bit easier. The bad news is that they can also introduce new cyber risks and even more stress.
There are two things that cybercriminals are always on the hunt for: people’s identity data from their accounts, and their money. And during the tax-filing season both can be unwittingly exposed. Over the years, cybercriminals have adapted multiple tools and techniques to part taxpayers with their personal information and funds.
Let’s take look at some of the main threats out there and what you can do to stay safe.
What do they want?
Cybercrime is a highly efficient money-making business. Some reports suggest this underground economy generates as much as $1.5 trillion each year. (See Into the Web of Profit, April 2018, McGuire, Bromium.) And tax-related scams are an increasingly popular way for the bad guys to drive-up profits. The Internal Revenue Service (IRS) claims that “thousands of people have lost millions of dollars and their personal information” to such attacks.
The bottom line is that they’re after one of two things: to trick you into wiring funds to them, and/or to get hold of your personally identifiable information (PII), including bank account and Social Security Numbers (SSNs). This personal data can subsequently be used to defraud you or the IRS, or may be deployed in follow-on identity fraud schemes to capture illicit funds from you.
There are various ways cyber-criminals can achieve these goals. The most common is by using social engineering tactics to trick taxpayers into sending money or personal information. But they might also use malware, either delivered to you personally or targeted at your tax preparer. This means you not only have to look after your own cybersecurity but also demand that the third-party businesses you work with store and transmit your sensitive information securely.
Look out for these scams
Here’s a round-up of the most popular tactics used by tax scammers today:
Impersonation: The fraudster gets in touch pretending to be an IRS representative. This could be via email, phone, social media or even SMS. They usually claim you owe the IRS money in unpaid taxes or fines and demand a wire transfer, or funds from a prepaid debit card. Sometimes they may ask for personal and financial details—for example, by claiming you’re entitled to a large tax refund and they just need you to supply your bank account info.
These interactions are usually pushy. The scammer knows the best way of making you pay up is by creating a sense of urgency and, sometimes, shaming the individual into believing they’ve been withholding tax payments. Phishing emails may look highly convincing, right down to the logo and sender domain, while phone callers will use fake names and badge numbers. Sometimes the scammers use personal data they may have stolen previously or bought on the Dark Web to make their communications seem more convincing.
In some impersonation scams, the fraudsters may even pretend to work for charities and ask for personal details to help disaster victims with tax refund claims.
Spoofing, phishing, and malware: In some cases, a text, email or social media message spoofed to appear as if sent from the IRS or your tax preparer actually contains malware. The scammers use the same tactics as above but trick the recipient into clicking on a malicious link or opening an attachment laden with malware. The covert download that follows could result in: theft of your personal information; your computer being completely hijacked by hackers via remote control software; or a ransomware download that locks your computer until you pay a fee.
Fake tax returns: Another trick the scammers employ is to use stolen SSNs and other personal information to file tax returns on your behalf. They can then try to claim a large payment in tax refunds from the IRS. The PII they use to file in your name may have been taken from a third-party source without your knowledge, and the first you might hear of it is when you go to file a legitimate tax return. It can take months to resolve the problem.
Attacks targeting tax preparers: Over half of Americans use third-party tax preparation companies to help them with their returns. However, this offers another opportunity for scammers to get hold of your sensitive information. In one recently discovered campaign, malware deployed on tax preparers’ websites was designed to download to the visitor’s computer as soon as they loaded the page. The IRS warns that businesses large and small are potentially at risk, as scammers are keen to get hold of tax information which enables them to file highly convincing fake returns in your name.
What to do
The good news is that by taking a few simple steps you can insulate yourself from the worst of these scams. Remember: the IRS does not contact taxpayers by email, text messages or social media to request personal/financial information— so if you receive communications that do, they are definitely a scam. It’s also important to remember that scams happen all year round, not just in the run-up to the tax filing deadline. That means, unfortunately, that you need to be on your guard all the time.
Here are a few other recommendations:

It also pays to demand that your tax preparer take their own precautions to keep your data secure. They should not be sending sensitive data or documents unencrypted in emails and must take steps on their own to combat phishing emails that target employees, since these can cascade to you during your tax preparation process. Whether hosted in the cloud or running on-premises, the servers that hold your data should also have adequate protection—and you have a right (and a duty to yourself) to ask ahead of time what they’re doing to protect it.
According to the IRS tax preparers should put the following internal controls in place:
