Ransomware and phishing have always been linked, but the old model was blunt: a phishing email carried the payload, the recipient opened it, encryption followed within hours.

Fortinet has found a new TrickBot variant hiding commands in DNS traffic and using scheduled tasks and added modules to maintain access on infected Windows PCs.

Recently, our teams in Latin America investigated a series of incidents involving misconfiguration, the deployment of BitLocker, and the exploitation of corporate printers. Attackers used the devices to notify organizations that their infrastructure had been compromised and they had to pay a ransom to recover their data.

This article analyzes two incidents that occurred in June in Colombia and in May in Mexico. We highlight the similarities in the attackers’ communications and outline emerging trends in ransom amounts.

Initial sign of an attack

In both cases, the affected users initially noticed a padlock icon next to their drives in Windows Explorer. This indicated that the drive was encrypted with BitLocker, blocking access to its contents.

A recovery key was required to unlock the drive.

This is not the first time we have seen such threats; a few years ago, our team discovered a threat known as ShrinkLocker, which utilized BitLocker to achieve its goals.

First case: abusing RDP to encrypt data

One of the incidents occurred in Colombia in June. The attackers exploited an internet-exposed RDP service on a machine connected to an 8 TB storage device containing mission-critical data. After taking control of the system and manipulating user credentials, the attackers enabled BitLocker exclusively on the drive that primarily stored financial data. Once the encryption was complete, they locked the drive and used the company’s printers to produce ransom notes.

Unfortunately, it was not possible to obtain evidence in the case due to the company’s rush to restore the encrypted disk. The communication with the attackers revealed a demand for just $3,000, and the company considered paying the ransom. After that, the system was restored before the forensic team could take any action, eliminating the evidence needed to assess the incident.

This attack was made possible by an internet-facing remote desktop service (RDP) with additional open ports, which employees used to access corporate information. By exploiting this network exposure and misconfiguration, attackers breached the system, identified an additional drive, and leveraged BitLocker to encrypt the data and demand a ransom payment. Leaving RDP ports open without proper security controls jeopardizes the security of systems and information, as highlighted in the our “Global Report: Anatomy of a Cyber World“.

The company confirmed that, due to compatibility issues with applications required for operation, EPP (Endpoint Protection Platform) protection was disabled on the system, making it easier for attackers to validate, enumerate, and execute applications without revealing malicious activity to central monitoring systems.

Second case: meet the XEntry Team

In another incident, which occurred in Mexico in May, our team identified how the threat actor gained initial access to the infrastructure. They exploited a misconfigured MSSQL service. This allowed them to execute commands on the system after obtaining the database login credentials from code insecurely published on GitHub.

In this incident, the attack began three months prior to detection, with the intruder discovering and verifying their access to the environment. After confirming their access and privilege level within the MSSQL server settings, which extended beyond the DBMS to the underlying operating system, the attackers initially focused on manipulating certain aspects of the web server configuration on the same system. They lowered the server’s security settings and created web shell files in the publicly accessible folders. Many of these attempts to manipulate the service or create malicious files were contained by existing EPP security controls, but despite the alerts, the necessary investigation to address the activity was not conducted.

The attackers subsequently confirmed their ability to execute commands locally and set up their attack infrastructure to transmit data via a communications bridge. By exploiting the MSSQL service, they gained access to each of the organization’s internal systems.

The database engine used by the company was Microsoft SQL Server 2019.0150.2160.04, misconfigured to allow operating system сommand execution via the xp_cmdshell extended stored procedure.

Due to this misconfiguration of an internet-exposed service, the attackers established a channel capable of executing any type of command directed at the server and the local infrastructure within its scope.

One of the main objectives was to identify shared systems and resources that provided access to critical information. Our analysis confirmed the attackers’ access to systems storing configuration parameters for networking, enterprise management, and cloud services, among others.

In early May, the attackers focused on running additional scans and deploying ManageEngine’s Endpoint Central RMM (Remote Monitoring and Management) to establish persistence and begin the final stages of their intrusion.

Further RMM-type applications, such as Mesh Agent and Tactical RMM, were installed in the days that followed. These were used to deploy scheduled tasks responsible for enabling the BitLocker service and individually encrypting the infrastructure’s disks, generating a key for each encrypted system.

Finally, in mid-May, the attackers managed to execute a Group Policy Object (GPO) used to deploy activation and encryption tasks, as well as other policies responsible for continued deployment of RMM applications via scheduled tasks. The activity initially targeted critical systems but later spread to every system synchronized with the domain controller. Users became aware of the attack when their machines displayed a blue screen with the message “Hacked by XEntry Team”, and their credentials stopped working to access their systems.

A few hours later, ransom notes began emerging from office printers.

These cases confirm that adversary’s objective is to gain access to infrastructure while avoiding investment in or partnership with ransomware groups. Instead, they leverage built-in Microsoft tools to facilitate data encryption and ransom payments. Monitoring and centralizing logs on protected resources, as well as promptly managing alerts, are critical to countering this type of intrusion.

Conclusions

• Although the systems under review had security measures in place, there was a lack of proper alert management or inadequate decisions regarding application incompatibilities.
• We strongly recommend configuring the Remote Desktop Protocol (RDP) in strict accordance with cybersecurity best practices to prevent unauthorized access. This is especially critical: according to our Global Report: Anatomy of a Cyber World, more than 13% of incidents are related to policy violations and configuration errors, confirming that misconfigurations continue to pose a significant risk.
• Organizations should prioritize strict application control policies and active monitoring of network traffic for command-and-control (C2) communications. This is especially critical: according to the same report, more than 20% of incidents involved the abuse of RMM (Remote Monitoring and Management) tools for execution and C2 strategies. The fact that attackers used more than three distinct tools to gain control during a single incident further underscores the urgent need for these measures.
• Some questions remain unanswered due to a lack of evidence and a hasty system restoration effort that bypassed critical stages of the incident response process. It is important to ensure an adequate incident response procedure, preserving evidence to confirm all related activities, and adjusting or proposing controls to prevent future incidents involving similar TTPs.
• Although the ransom notes do not reveal a clear connection between the actors, certain words used in the messages, as well as the method of delivery and communication, may confirm a link:

“As a guarantee, we have no negative online reviews about non-fulfillment of our obligations…” (Ransom note from the first case)

“Our reputation is the guarantee that all content will be fulfilled…” (Ransom note from the second case)

Our teams continue to monitor these threats.

Welcome back, aspiring investigators! 

Let’s talk about something that has become one of the biggest problems in the crypto world. It’s drainers. If you haven’t heard the word before, don’t worry, you’re about to become very familiar with it. Drainers are a type of phishing attack, and they have swept through the cryptocurrency world at a truly striking pace. In fact, they are now growing so fast that they have already overtaken ransomware, both in how widespread they are and in the sheer amount of money they steal. To understand exactly how this works, we dug into the mechanics of drainers as well as the whole shadowy little market that has grown up around them. That’s what we are going to explore together today.

The basic idea behind any phishing campaign is to catch you making a mistake. Hackers want you to hand over information or access that should never leave your hands. In the specific case of drainers, the goal is a little different from classic phishing. The hacker wants to trick you into granting a smart contract permission to interact with your funds. Once you give that permission, the damage is already done. Drainers mostly go after blockchains that support smart contracts. That means they target users on Ethereum and Ethereum-like networks, such as Base, Polygon, and Optimism. But don’t think Ethereum is the only battlefield. Drainers built for Solana exist too, and a drainer aimed at Bitcoin has already made an appearance.

Imagine you want to connect your MetaMask wallet to some project’s website because you’re hoping to grab a little free crypto. Maybe you want to buy a brand-new token while it’s still cheap, before the price shoots up. You click Connect, you type in your password, and you sign a transaction that approves access to your wallet. And that, right there, is exactly the moment a drainer catches you. Instead of a legitimate contract that would let you receive tokens, the hacker gets you to sign a malicious smart contract. In doing so, you unknowingly grant permission for your funds to be transferred out. In effect, you agree, with your own hand, to give away all your money.

So how does a hacker actually pull this off? It works best with something called an airdrop, which is simply a giveaway of new tokens. Airdrops attract a swarm of people who are hoping to get a little bit of crypto that might grow tens of times in value down the road. These giveaways do genuinely happen sometimes, as a real way to promote a new token. So people have learned to trust them. In that exact moment, the user is driven by something we call FOMO, the fear of missing out on a gain.

In their rush to grab the airdrop, a person often doesn’t stop to check who actually created the page they are interacting with, or what the smart contract they are approving actually does under the hood. The website itself might be a perfect copy of the real one, built by the hacker down to the smallest detail, while the smart contract underneath does the opposite of what it promises. Instead of giving you money, it takes it.

Drainers Are Gaining Momentum

In 2024, drainers overtook ordinary ransomware, both in how far they spread and in how much money they brought in. Now, don’t get it wrong, ransomware is still very much the scourge of large businesses. But scammers, being the opportunists they are, have rushed into this new and still relatively uncrowded niche. The very first drainers spread quietly, as scripts traded on darknet marketplaces. Back in 2022 there were 55 unique forums where you could find drainers being sold or discussed. By 2024, that number had jumped to 129 such places, more than double in just two years.

And keep in mind, that count only covers a place as niche and honestly as sparse as the dark web. Most of the real action these days happens on Telegram and Discord.

The biggest drainers active in 2024 had names like Angel, Inferno, Ping, Ace, Cerberus, Nova, Medusa, MS, CryptoGrab, and Venom. Of that whole list, mainly Angel and Ace are still active today, but a new player has stepped onto the stage, one called Vanilla. It hasn’t been studied very closely yet, because it runs on a private model that is difficult for the average scammer to even get access to.

According to Scam Sniffer, a company that closely analyzes different types of crypto fraud, total losses from drainers in 2024 added up to $494.000.000.

That figure only counts the large-scale hacks that could actually be tallied and confirmed. Since drainers mostly target ordinary, everyday users, small thefts of just a few thousand dollars here and there don’t even make it into that statistic. So the real number is almost certainly much higher. 

Among the large-scale cases recorded in 2024, there were more than three hundred thirty thousand victims. The single biggest theft that year came to $55.000.000. All together, there were roughly thirty major fraudulent campaigns, which is one and a half times more than the year before, in 2023. In the first quarter of 2024 alone, drainers showed almost sixfold growth. Compare that to ransomware, which only doubled over that same stretch of time.

So what do all these numbers really mean? Well, because the barrier to entry into this line of work is so remarkably low, it has started attracting scammers who used to work in more old-fashioned territory, like email phishing, luring victims to fake bank login pages and other traditional scam types. A couple of months of this kind of work could buy an apartment, a car, and regular vacations somewhere warm like Thailand. Take one risk, and you can just walk away, or so the thinking goes. But of course, once someone gets a real taste of easy money like that, nobody actually walks away after two months. The business pulls them back in.

Think about the contrast here. A ransomware group has to negotiate with a company, arrange for payment, and handle the whole business of decryption afterward. That’s a lot of hassle and a lot of steps where things can go wrong. A drainer, on the other hand, just steals the money immediately. No negotiation needed. 

Like plenty of other kinds of scams out there, drainers are distributed under what’s called a SaaS model, short for Software-as-a-Service. In this criminal corner of the internet, they’re called DaaS, meaning Drainer-as-a-Service.

There’s also a very characteristic division of labor inside these operations. You’ve got developers, who build the actual malware. You’ve got workers, the rank-and-file operatives out doing the scamming day to day. And alongside them you’ve got recruiters, traffic-generation specialists, and providers of various supporting services that keep the whole machine running. The main job, naturally, falls to the developers. They are the ones who create the malicious software and work to make it more convenient to use, easier to deploy, and easier to scale up. 

How the “Company” Is Built

So what does a hacker actually need in order to pull off a phishing campaign like this?

First, they need domains for their future sites, and these domains are usually spelled just similarly enough to the name of the real project they’re impersonating, so a distracted eye won’t catch the difference. Then they need hosting, which is simply a place to put the site once it’s built. Naturally, they also need a landing page, one designed to closely resemble the legitimate project’s real page. Underneath that landing page sits the drainer code itself, which is typically JavaScript code hosted directly on the site. On top of all that, they’ll usually build a control panel that shows them how many users have been lured in and tracks how those users are behaving on the page. And finally, hackers take their own security seriously too, relying on VPNs, proxies, and fake sockpuppet accounts to cover their tracks.

Professional hackers usually go a step further and set up a full command-and-control server, which lets them manage the drainer’s behavior remotely and adjust it on the fly.

Once all of that infrastructure is in place, all that’s left is bringing in people, actual victims to walk through the trap. That job falls to traffic arbitrage specialists, sometimes called traffic drivers. Their whole task is to funnel users toward the phishing page. They accomplish this in all sorts of ways, everything from buying Google ads to jumping directly into comment sections and posts to engage with real users. Some scammers even go so far as to clone the official support channels of legitimate projects, so a victim reaching out for help ends up talking to the scammer instead.

Put it all together, and what you get is a genuine sales funnel, a designed path that walks victims toward the trap, just like any legitimate marketing funnel would walk a customer toward a purchase.

How the Money Is Split

Here’s how the profits typically get divided up. Operators, the people running the overall scheme, take home twenty to thirty percent of whatever gets stolen. The rest goes to the workers, the people directly out there scamming victims day to day. A worker’s exact cut depends on their skill level. Beginners give up thirty percent of their take to the operators, while the most experienced workers only give up ten to fifteen percent.

And how is a worker’s skill level judged? Simply by how much they have already managed to steal over time. If you’ve stolen up to $10.000 total, you’re considered a beginner. Between $25.000 and $30.000 puts you at mid-level. And starting from $100.000, usually climbing toward a million or more, you’re considered a true professional in this dark little trade.

Driving Traffic

Knowledge in this underground world gets passed around among workers through tutorials. A tutorial itself becomes an item that gets bought, sold, and traded, almost like a piece of merchandise. Entire communities have formed just to gain access to these tutorials, treating them like valuable trade secrets. The writing style of these tutorials makes it fairly clear that AI tools were used to help put them together.

Broadly speaking, the same traffic-driving scheme used in ordinary, everyday phishing applies here too, just adapted for the world of crypto. A worker is essentially doing the same job as any online advertising specialist would. Their goal is simply to increase the number of people clicking through to the phishing page. That means hunting for users who are genuinely interested in Web3 and DeFi projects, people who hold crypto wallets and who are drawn to airdrops, token swaps, and exchanges.

This whole process involves demographic analysis and geolocation analysis, essentially the same ordinary targeting techniques that any advertiser in any industry would recognize. Workers also handle what they call “site design,” which really just means cloning the pages of existing, trusted projects. They’ll even use classic marketing techniques like A/B testing to see which fake page tricks more people.

Now let’s walk through a few high-profile examples of drainer thefts.

The Attack on Arkham Intelligence

Arkham is a company that provides on-chain analytics, and it’s a genuinely popular tool for tracking transactions. Traders rely on it, for instance, to check an asset’s price and see exactly where it’s trading across different platforms.

Back in 2023, Arkham’s owners launched their own token along with an airdrop of coins to celebrate. But hackers saw an opportunity and created numerous fake profiles on X specifically to redirect users toward phishing pages containing a drainer. Remarkably, these bot accounts proved quite resilient and managed to avoid being banned for a long stretch of time. They mimicked Arkham’s real activity closely and spread malicious links far and wide.

A huge number of these fake sites were created during the campaign, and each one typically had a lifespan of just weeks, or a couple of months at most. Angel’s software allowed a hacker to copy landing pages quickly and place them on brand-new domains almost instantly. The whole process has been simplified so much that a worker only needs to type a few commands into a conversation with a Telegram bot in order to deploy an entirely new phishing site.

The Attack on the SEC

An even bigger impact can be achieved by a hacker hijacking the real, verified account of some authoritative company, or even a government organization.

And that’s what happened with the United States Securities and Exchange Commission, or the SEC. On January 9, 2024, its account on X was compromised through a technique called SIM swapping, which basically means reissuing a SIM card tied to the phone number linked to that account. Officials, unfortunately forgetting about basic security hygiene, hadn’t even enabled multi-factor authentication on the account.

Lately, the SIM-swapping community and the drainer community have grown noticeably closer, almost like two neighboring criminal industries starting to collaborate. Swappers now routinely supply drainers with freshly hijacked accounts to use.

The hackers behind this attack posted that the SEC had officially approved investing in Bitcoin without needing to buy crypto directly on an exchange like Binance or Coinbase. This caused an immediate stir, because investors had been waiting a long time for exactly this kind of decision from the SEC, and many expected it to be announced any day. Following the fake post, the hackers urged people to claim an “official SEC airdrop” on a special site that contained a drainer.

That single fake post even caused a real spike in Bitcoin’s price. It rose by a full thousand dollars, just from a fake tweet.

Scamming the Scammers

Scammers, as it turns out, wouldn’t really be scammers if they didn’t also scam each other. At one point, the developer behind the Pink Drainer felt like he was getting close to being unmasked, so he decided to get out of the game entirely and cash out his loot. Here’s the catch, though. You can’t just sell crypto obtained through a scam outright. To actually withdraw the funds, a scammer first has to launder the money, or else an exchange might get suspicious and freeze it before it ever reaches a real bank account.

To avoid enabling things like terrorism financing, or simply to stay within the law, exchanges use a system of scoring and refuse to accept “dirty” crypto. This scoring system is called an AML score, short for anti-money-laundering. There are plenty of laundering methods out there, and while trying one of them, Pink Drainer’s own developer ended up getting scammed himself.  He fell for one of the simplest kinds of fraud imaginable called address poisoning. 

Here’s how it works. Hackers generate crypto addresses that closely resemble a victim’s real address, and then they send that victim a tiny amount of crypto, just enough so that the lookalike address shows up in the victim’s transaction history.

From the user’s side, here’s what it looks like in practice. You send, say, one hundred dollars to some other wallet, maybe an exchange you use regularly. Then, five or ten minutes later, you receive a few tiny transfers that appear to come from that very same wallet. But in reality, they only come from a similar-looking address, one that might share, say, an identical start and end to the real address, while the middle is different.

The hacker is betting that on your next transfer, you’ll simply scroll through your history, pick the most recent address you see, and send your money not back to yourself, but straight into the hacker’s pocket. And that’s exactly how Pink Drainer got caught in his own kind of trap. He picked what looked like the last transaction in his history and sent ten ETH, worth about $15.000 at the time, straight to some unknown “colleague” who was never really his colleague at all.

Conclusion

Because draining is so easy and profitable, this type of scam is not going away anytime soon. If anything, the ways malicious payloads get delivered will only keep getting more sophisticated from here. Drainers are increasingly setting their sights on younger blockchains too. On Ethereum-based networks, it’s steadily getting harder for hackers to operate, since protective measures keep appearing that they have to find new ways to bypass. On Solana, though, no such protections really exist yet, which makes it a much softer target. New kinds of drainers will keep emerging as well. Some scammers have already started building actual apps for Google Play and the App Store, moving beyond simple websites and into places millions of people trust by default. So stay alert out there, and think twice before you click any button, especially one promising you free money. If it feels too good to be true, in crypto more than almost anywhere else, it usually is.

If you’re interested in cryptocurrency forensics, we have a dedicated training called Bitcoin and Cryptocurrency Forensics. You will get to dive into blockchain analysis and cryptocurrency investigations, learning the skills needed to become a cryptocurrency forensic analyst.

All threats

The percentage of ICS computers on which malicious objects were blocked continued to decrease, reaching 19.6% in Q1 2026. This is the lowest value in three years, and it is 1.4 times lower than in Q2 2023.

Regionally, the percentages ranged from 9.1% in Northern Europe to 27.4% in Africa.

The percentage of ICS computers on which malicious objects were blocked increased in five regions over the quarter, most notably in Southern Europe, Northern Europe, and Russia.

In Q1 2026, Southern Europe led the way in growth for internet and email threats. The region also saw the fastest growth in spyware, as well as malicious scripts and phishing pages.

In Russia, the percentage of ICS computers on which malicious objects were blocked exceeded the figures for the previous two quarters. Russia saw an increase in the percentage for threats from the internet, and a slight increase in the figure for threats from email clients (Russia is one of three regions where this figure did not decrease).

Among the threat categories, the greatest increases were observed in the percentages for denylisted internet resources, as well as spyware (distributed in the region via the internet and email clients).

Selected industries

Biometric systems (26.4%) traditionally rank top among the industries and OT infrastructure types covered in this report in terms of the percentage of ICS computers on which malicious objects were blocked. These systems are characterized by internet access, extensive email use for data exchange and approvals (such as access granting), and, in many cases, minimal cybersecurity controls within the organizations that use these systems.

Biometric systems rank first among industries in terms of email threats. At the same time, unlike other industries, the percentage for email threats in biometric systems exceeds that for internet threats.

In all selected industries, the global average follows a downward trend. In Q1 2026, the percentage of ICS computers on which malicious objects were blocked increased only in the manufacturing sector — by 1.0 pp. The percentages for this industry increased across 10 regions, with the most notable increases in Western Europe, Northern Europe, and Russia.

Threat categories

In Q1 2026, Kaspersky security solutions blocked malware from 10,052 different malware families of various categories on industrial automation systems.

Over the quarter, the percentage of ICS computers on which denylisted internet resources were blocked increased (after decreasing over the previous two quarters), and there was a slight increase in the percentage for AutoCAD malware.

Malicious scripts and phishing pages (JS and HTML)

Malicious scripts and phishing pages retained their to spot among threat categories by the percentage of ICS computers on which these threats were blocked. The global average in Q1 2026 was 6.56%.

Over the quarter, the percentages increased in four regions. The most significant change was observed in Southern Europe (9.85%, +0.94 pp). The figures for malicious scripts in the region increased over three consecutive quarters.

Among the selected industries, across all regions, the highest percentages for the malicious scripts and phishing pages category were recorded for biometric systems (19.59%) and building automation (15.43%) in Southern Europe. These same industries lead in similar rankings for malicious documents and spyware.

Spyware

The percentage of ICS computers on which spyware was blocked decreased over two consecutive quarters, dropping to 3.73%. Despite the decline, spyware has ranked second among threat categories by the percentage of attacked computers for three consecutive quarters.

The percentages increased in five regions over the quarter, most notably in Southern Europe (5.46%, +0.35 pp) and Russia (2.84%, +0.24 pp).

In Southern Europe, the percentage of ICS computers on which spyware was blocked increased in all the selected industries except manufacturing. The greatest increase was observed in biometric systems.

Among the selected industries, the highest percentage of spyware in Russia was recorded in biometric systems. That said, the percentage of ICS computers on which spyware was blocked increased in all industries in the region except construction. The percentage figure has been increasing for two consecutive quarters in the oil and gas industry (by a factor of 1.63 over six months), and for three consecutive quarters in engineering and ICS integration, as well as electric power. In the remaining sectors, the values have been fluctuating.

Denylisted internet resources

The percentage of ICS computers on which denylisted internet resources were blocked increased to 3.54%.

The most notable increase over the quarter occurred in Southeast Asia (4.58%, +0.65 pp). Among the industries in the region, the highest percentage figures for this threat category were recorded in electric power and construction. Over the quarter, the largest increases in percentages figures were observed in the electric power and manufacturing industries.

In North America (Canada), denylisted internet resources (2.14%) showed the greatest increase among all categories — by a factor of 1.22.

Among the selected industries across all regions, the highest percentage figures for the denylisted internet resources category were in the electric power (7.11%) and construction (6.25%) industries in Southeast Asia.
