Good Europol Hunting: How Do You Like Them Apples, Emotet?
Combating Ransomware

On January 27, 2021, Europol announced that it had led a coordinated takedown of the Emotet infrastructure in collaboration with law enforcement authorities in the Netherlands, Germany, the United States, the United Kingdom, France, Lithuania, Canada, and Ukraine.
According to Europol, over the course of the operation, it has been able to map out and take control of servers from around the world that Emotet was using as “command-and-control” (C2) nodes. Europol also shared that it would use the seized servers to deactivate Emotet by pushing an update to all infected systems still connecting to the seized C2s. Analysis of the new Emotet updates, which were developed by Europol, shows code that will self-remove the Trojans from infected systems on March 25, 2021, at 12:00 (local time).
“As part of the criminal investigation conducted by the Dutch National Police into EMOTET, a database containing e-mail addresses, usernames and passwords stolen by EMOTET was discovered. You can check if your e-mail address has been compromised. As part of the global remediation strategy, in order to initiate the notification of those affected and the cleaning up of the systems, information was distributed worldwide via the network of so-called Computer Emergency Response Teams (CERTs).”

The Ukrainian National Police agency also reported making some arrests in connection with this operation.

Emotet Overview
Emotet is a sophisticated banking Trojan that security researchers first identified in 2014. Originally, it was designed to steal banking credentials for use in taking over bank accounts and stealing funds from victims. Over the years, its functionality was updated to enable hackers to deploy supplementary malware and steal content from victims’ email systems.
In mid-2018, the Emotet group started to work closely with operators of the TrickBot banking Trojan and Ryuk/Conti ransomware groups. After initial infection, Emotet can stay undetected for weeks, sometimes months, before it eventually deploys the TrickBot Trojan, which can then lead to a subsequent ransomware attack. In the last few months, Emotet has also been seen deploying IcedID and Qbot Trojans, which can also lead to ransomware attacks by the MegaCortex, Prolock, and/or Maze/Egregor variants.
Emotet Risk Assessment
On October 12, 2020, Microsoft announced a similar takedown of the Trickbot infrastructure. In this case, the botnet’s owners were able to rebuild their infrastructure and restart operations in about four weeks. In part, this quick reboot was thanks to the Trickbot banking Trojan having a “fallback” communications module, which uses a blockchain distributed domain name service (DNS) technology called Emercoin DNS (EmerDNS) that law enforcement cannot take over. After the Trickbot operators deployed a new set of C2 servers, they were able to use the fallback channel to update configurations on infected systems.

It’s all about the money. Cold. Hard. Cash.
Unlike Trickbot, Emotet does not have a similar fallback capability and cannot regain access to infected systems to update configurations. Therefore, it will likely take the Emotet group longer to recover and resume operations. Based on the Arete Cyber Threat Intelligence (CTI) team’s assessment, the takedown of the Emotet C2 infrastructure will disrupt this botnet’s operations for at least five to six weeks.

Europol Disrupts AudiA6 Crypto Laundering Service
European authorities have dismantled AudiA6, a major cryptocurrency laundering service linked to ransomware groups and broader cybercriminal networks. Between 2022 and 2025, the platform is believed to have processed over €336 million in illicit funds, enabling threat actors to obscure financial trails and monetize cybercrime proceeds. Its operators are also suspected of running Dark2Web, a dark web forum that facilitated collaboration, services, and connections among cybercriminals globally. This development underscores the expanding role of sophisticated, large-scale cryptocurrency laundering services in sustaining the cybercrime economy, enabling threat actors to obscure illicit funds and evade regulatory controls.
What’s Notable and Unique
Following law enforcement disruption of Cryptex and Garantex, AudiA6 emerged as another platform involved in financial activities linked to ransomware groups. Investigators believe that AudiA6 became a central hub for cybercriminals seeking to launder stolen digital assets while obscuring the transaction trail from authorities.
On June 10, 2026, a coordinated operation resulted in two arrests in Georgia, the dismantling of key infrastructure (30+ servers, 25 domains), the freezing or seizure of over €778,000 in crypto, and the takedown of the AudiA6 and Dark2Web platforms.
Analyst Comments
Ransomware groups and cybercriminal networks are increasingly leveraging sophisticated techniques, including chain-hopping, decentralized exchanges, and mixer-as-a-service platforms, to rapidly move illicit cryptocurrency across multiple blockchains, effectively obscuring transaction trails. Concurrently, the widespread use of fraudulent exchange accounts, mule wallets, and privacy-enhancing tools has elevated cryptocurrency laundering to a core enabler of the cybercrime ecosystem, allowing actors to bypass anti-money-laundering controls at scale. This investigation identified over 6,000 KYC records linked to money-mule accounts, many of which were tied to Russian-speaking intermediaries specifically recruited to facilitate the movement of illicit proceeds. These threat actors systematically used both commercial and domain-controlled email services to establish mule accounts across multiple cryptocurrency platforms. Collectively, these findings underscore the growing scale, coordination, and professionalization of cryptocurrency-enabled crime, highlighting the critical need for sustained, intelligence-led, and internationally coordinated efforts to disrupt these evolving financial ecosystems.

Threat Actors Leverage AI for EDR Evasion
A threat actor has developed and deployed a ransomware attack toolkit enhanced with AI-assisted development workflows, enabling automated Active Directory (AD) discovery and improved EDR evasion capabilities. The toolkit leverages agent-based AI systems, such as Claude’s Opus and Cursor agents, for iterative malware development, testing, and refinement.
What’s Notable and Unique
Researchers have highlighted that this toolkit can not only generate ransomware code but also bypass sophisticated security defenses and identify AD networks for malware distribution.
The framework incorporates multiple capabilities, including automated AD discovery and reconnaissance mechanisms, iterative EDR testing environments to refine evasion techniques, and a command-and-control (C2) infrastructure that leverages Telegram APIs and Cloudflare redirectors for stealth.
Additionally, some agents were tasked with checking security research and technical posts for various bypass techniques. The agents recognized what was required for reproduction, extracted the techniques, mapped them to the MITRE ATT&CK knowledge base of adversary behaviors, set up a test lab, carried out the methodology, and reported the results.
After a few repetitions, the modules seemed to avoid nearly all EDR solutions, despite the agent’s initial suggestion of a high failure rate. Although researchers found no evidence that AI was embedded in deployed malware or was operating independently in victim environments, the technology was still used to accelerate the iterative process of developing, testing, and refining payloads against security products, shortening the period between the publication of offensive security research and its practical implementation by threat actors.
Analyst Comments
AI-driven tools like this could accelerate the pace and sophistication of ransomware attacks, enabling even relatively inexperienced actors to launch high-impact campaigns. This development underscores the urgent need for security solutions to adapt to AI-assisted threats. Organizations must respond by strengthening detection engineering, improving visibility across environments, and maintaining robust security fundamentals.

CMS Vulnerability Leads to ClickFix Campaign
Threat actors compromised at least 700 education and technology websites in a recent ClickFix campaign by exploiting a critical SQL injection flaw (CVE-2026-26980) in the Ghost content management system (CMS). Adversaries combined the vulnerability with the ClickFix social engineering tactic to steal admin keys and inject a malicious JavaScript that delivers a fake Cloudflare or CAPTCHA verification pop-up, tricking victims into copying and pasting a malicious command into their systems.
What’s Notable and Unique
Rather than targeting the end user first, this campaign is unique in its initial exploitation of the system, followed by social engineering attempts. This hybrid attack style is likely being leveraged to bypass traditional defenses.
This recent campaign also highlights how trusted web properties can be weaponized at scale and coupled with unpatched CMS vulnerabilities. Rather than using the CMS compromise to perpetrate a single attack, threat actors turned it into a supply-chain attack that ultimately affected over 700 trusted websites.
Analyst Comments
As network defenders and their tools enhance threat detection capabilities, adversaries increasingly seek methods to bypass these defenses. By combining vulnerability exploitation, social engineering techniques, and staging for ancillary attacks, this campaign successfully bypassed traditional defenses and inflicted significant impact. Defending against hybrid cyberattacks requires comprehensive security controls beyond simply patching vulnerabilities. Organizations should focus on limiting movement within the environment, detecting abuse of trusted applications, and preventing end-user manipulation.
