A new study by Secureworks' Counter Threat Unit (CTU) has revealed that ransomware operations have shifted significantly in response to heightened law enforcement crackdowns, forcing threat actors to evolve their strategies accordingly. There has been a tradition of many ransomware groups relying on affiliate models, including the LockBit gang, which involves recruiting external partners to carry out attacks in exchange for a share of the ransom payment.
Cybercriminal organizations are beginning to be forced to adjust in order to maintain profitability and operational reach in the face of sustained global enforcement efforts and coordinated takedowns, forcing them to rethink how they operate so they can remain profitable and profitable. In response to the changing landscape in ransomware, groups such as DragonForce and Anubis have been observed to adopt innovative frameworks for attracting affiliates and maximizing profits.
In addition to evading legal scrutiny, these emerging models also appear to be designed in such a way as to offer collaborators more incentives and flexibility than previously offered by traditional methods. In a hostile environment in which traditional tactics are becoming increasingly risky and unsustainable, these groups are readjusting their internal hierarchies and engagement strategies in order to maintain momentum.
There is a clear indication that this evolution indicates that the underground ransomware economy is undergoing a significant transformation. This shift is being driven by the growing influence of international cyber defense efforts, as well as criminals' ability to adapt to escalating pressure. It is estimated that more than 700,000 computers were infected worldwide by the malware campaign at the centre of the investigation, including approximately 200,000 systems within the United States.
Despite the prevalence of this infiltration, 58 million dollars in financial losses have been directly linked to ransomware activities in the last 24 hours, highlighting the scale and sophistication of this criminal network.
According to U.S. Attorney Martin Estrada, Operation Duck Hunt has been the largest technological and financial operation ever conducted by the Department of Justice against a botnet. The operation is a comprehensive enforcement initiative that is aimed at capturing the infrastructure behind the botnet, a process that has been ongoing for several years.
There was a successful operation in which 52 servers critical to the botnet were taken down and more than $8.6 million in cryptocurrency assets were seized, used to facilitate or conceal illicit gains. In spite of these remarkable achievements, cybersecurity experts caution against interpreting the disruption as a definitive victory. As is often the case when it comes to cybercrime enforcement, what appears to be the end may actually only be a temporary setback when it comes to the criminal activity.
A cybercriminal ecosystem is resilient, adaptable, and able to evolve very quickly, which results in the emergence of new variants, techniques, or successor operations in a short period of time to fill the void left behind when a network has been dismantled. In the dynamic and ever-evolving cyber threat landscape, it is important to recognize that federal agencies are capable of performing complex takedowns, but that they also face a persistent challenge in achieving lasting impact.
There has been a recent international crackdown targeting a particular type of malicious software called "initial access malware," which is one of the most critical enablers in the overall lifecycle of cyberattacks, according to statements released by Europol and Eurojust. As malware strains are typically deployed as early as possible in the course of a cyber-attack, they allow threat actors to quietly breach targeted systems and establish a foothold from which additional malicious payloads can be deployed, such as ransomware.
Attempting to disrupt the foundational layer of the so-called "cybercrime-as-a-service" ecosystem by dismantling these tools was an important part of the authorities' effort. Its aim was to provide cybercriminals worldwide with flexible and scalable access to the services they needed. As part of the coordinated operation, a number of well-known malware variants were neutralized, including Bumblebee, Lactrodectus, Qakbot, DanaBot, HijackLoader, Trickbot, and WarmCookie, each of which has played a significant role in numerous ransomware attacks and data extraction.
Several authorities emphasized that the strike of these elements at their root greatly undermines the ability of downstream criminal operations by preventing them from functioning and limit the ability of malicious actors to carry out large-scale attacks, as well as significantly limiting the capabilities of the malicious actors. Nearly 50 command-and-control servers were successfully neutralized in Germany, where a significant portion of the law enforcement activity was concentrated.
There has been an investigation conducted by the German Federal Criminal Police Office (BKA) and the Frankfurt Public Prosecutor's Office for Cybercrime on the grounds of organized extortion and suspected affiliations with foreign criminal organizations based on suspected organized extortion. In response to this effort, international arrest warrants were issued for twenty individuals, most of whom were Russian nationals, and several search operations were conducted specifically to investigate these individuals.
Continuing Operation Endgame, which was regarded as the largest coordinated effort ever undertaken to fight botnets, this sweeping enforcement action represents a continuation of that effort. In addition to acquiring €21.2 million in assets, the operation has also demonstrated the global increasing momentum behind collaborative efforts to dismantle high-impact cybercrime infrastructure since it was launched in 2024.
Defendant Gallyamov and his co-conspirators allegedly orchestrated highly targeted spam bomb campaigns targeting members of the employees of victim organizations.
The attacks were designed to overwhelm recipients' inboxes with a barrage of messages, creating confusion and increasing the sense of urgency within them.
The attackers then exploited this chaos by impersonating an internal IT employee, contacting overwhelmed victims by impersonating a technical support representative, and offering technical assistance.
Once they had established trust and granted access, the attackers were quick to get their hands dirty—extorting data, deploying malware, encrypting systems, and ultimately demanding ransoms.
In this case, the backdoor was built using the highly sophisticated Qakbot malware, which was used to exploit compromised systems to deploy malicious payloads further encoding the credentials of the target systems, as well as collect login credentials across networks. Such access was a valuable commodity among the cybercriminals.
In the past, it has been suggested that Gallyamov and his network were monetizing these intrusions by selling access to operators of some of the most dangerous ransomware strains, such as REvil, Black Basta, and Conti, which are all dangerous strains of ransomware. In some cases, these ransomware groups are alleged to have compensated Gallyamov not only with direct payments but also by dividing a portion of the extorted profits with Gallyamov.
In April 2025, U.S. authorities seized more than 30 bitcoins linked to Gallyamov as well as approximately $700,000 in illicit assets.
Although these financial hits may have been significant, the primary suspect remains on the loose in Russia, out of reach of U.S. law enforcement due to the lack of extradition agreements. Despite the fact that Gallyamov faces a high probability of being captured, federal officials said that it would be unlikely that he would be brought to justice unless he voluntarily left the relative safety of his country.
The incident has served as a stark reminder of just how sophisticated social engineering and malware-based attacks are becoming as time goes by. Investing in enterprise-grade antivirus solutions and implementing advanced endpoint protection platforms are two of the best ways for organizations to protect themselves against such threats.
In many ways, these tools can be of great benefit in detecting unusual behavior, isolating compromised systems, and preventing the rapid escalation of attacks into full-scale data breaches or ransomware attacks that cause financial losses or reputational harm to companies.
