Cybercrime Crackdown: A New Chapter Begins
In a significant victory for international cybersecurity efforts, Europol has announced the arrest of the alleged mastermind behind XSS.is (formerly DaMaGeLaB), one of the most prolific Russian-speaking cybercrime platforms. This dramatic operation, spearheaded by French and Ukrainian authorities, marks a turning point in the global fight against digital crime. With over 50,000 users and deep ties to ransomware gangs and stolen data marketplaces, the dismantling of this platform sends a powerful message across the dark web.
Below, we dive into the details of this takedown, the implications for the cybercriminal ecosystem, and what cybersecurity professionals should expect next.
Inside the Arrest of XSS.is’s Administrator
The arrest took place in Kyiv, Ukraine, on July 22, 2025, as part of a coordinated effort between the French Police, the Paris Prosecutor’s Office, Ukrainian authorities, and Europol. This takedown is the result of a four-year investigation that began in July 2021. With the arrest, authorities also seized the clearnet domain of XSS.is, replacing the site with a law enforcement notice in collaboration with Ukraine’s SBU Cyber Department.
XSS.is was no ordinary forum—it was a dominant marketplace for hackers, offering a wide range of illegal products such as stolen data, hacking tools, ransomware services, and even encrypted communication channels. With over 50,000 registered users and 110,000 threads, it was a hub for some of the most active and dangerous cybercriminal operations globally.
The suspected administrator, whose name has not been disclosed, reportedly played a central role in managing the forum’s infrastructure and facilitating transactions. He acted as an escrow and arbitrator in criminal deals, ensuring both trust and security in illegal exchanges. This trusted role helped XSS.is stand out as a reliable place for illicit dealings. Additionally, he is believed to be behind another platform—thesecure.biz—which offered private messaging services tailored to criminals.
Investigators estimate the suspect earned approximately €7 million (\$8.24 million) in profits, primarily from advertising fees and paid dispute resolution. With a cybercrime career spanning nearly two decades, he is also said to have deep-rooted connections with several high-profile threat actors.
Since its inception in 2013, XSS.is has served as a fortress of anonymity for cybercriminals, especially those aligned with Russian-speaking hacker groups. It hosted an encrypted Jabber server, which allowed users to communicate secretly and securely. Alongside its counterpart Exploit, XSS.is formed the backbone of the Russian dark web ecosystem, focusing mostly on non-Russian-speaking countries.
A critical feature of the forum was its reputation-based trading system. Users were rated on their trustworthiness, and a dedicated escrow service ensured that transactions were protected from scams. This system fueled a thriving black market that operated with surprising professionalism.
The takedown of XSS.is follows another major Europol operation, which recently disrupted the infrastructure of NoName057(16), a pro-Russian hacktivist group. This group was responsible for a barrage of DDoS attacks across European targets, averaging 50 attacks per day. Between July 2024 and July 2025, they struck 3,776 unique targets—mainly government and public sector institutions in countries that oppose Russia’s war in Ukraine. Interestingly, the United States was notably absent from the list, despite its political alignment with Ukraine.
NoName057(16) operated with a layered command-and-control infrastructure, frequently rotating servers and applying strict access control measures. Their attack style was simple but highly effective—flooding servers with traffic to crash systems and disrupt services. Their favorite targets included Ukraine (29.47%), followed by France, Italy, Sweden, Germany, and others.
🔍 What Undercode Say:
The takedown of XSS.is is more than just the arrest of a single individual—it signals the collapse of a massive criminal infrastructure that enabled cybercrime to thrive unchecked for over a decade. Here’s what this means from a cybersecurity and underground economy perspective:
1. Decapitation Strategy Success
This arrest represents a successful “decapitation” tactic—cutting off the leadership to destabilize the entire operation. In the case of XSS.is, the administrator played a pivotal role not just in running the forum but in facilitating trust among criminals. His removal is expected to cause serious disruptions.
2. Trust Vacuum in Dark Web Markets
With the forum’s escrow services gone and its community scattered, criminals now face a trust vacuum. Transactions involving stolen data or malware rely heavily on third-party arbitration. This will likely lead to an increase in scams and disputes among remaining users, undermining the underground economy’s efficiency.
3. New Targets on the Radar
Other major forums like Exploit, BreachForums successors, and newer Telegram-based marketplaces could now fall under intensified scrutiny. Law enforcement might leverage the seized infrastructure and data from XSS.is to track and arrest further actors in the coming months.
4. Adaptation by Threat Actors
Although this is a major win, cybercriminals are known for their adaptability. We can expect a migration to decentralized platforms, stronger encryption protocols, and an increase in invite-only communities that are harder to infiltrate.
5. Geopolitical Implications
This move underscores a growing divide in the cyber realm between Russian-speaking hackers and Western law enforcement. As political tensions intensify, cybercrime is increasingly being used as a geopolitical tool. Arrests like this are both justice-driven and symbolic responses to that digital cold war.
6. Collaboration Model Reinforced
This operation also sets a benchmark for international cyber-policing collaboration. France, Ukraine, and Europol worked seamlessly across jurisdictions—a necessity in today’s borderless cybercrime landscape.
7. Disruption in Ransomware-as-a-Service (RaaS) Ecosystem
XSS.is was deeply connected to ransomware services. Its closure could interrupt access to payload builders, initial access brokers, and ransom negotiators, at least temporarily.
8. Undercode’s Perspective
As cyber defense professionals, we see this as a crucial psychological win. It proves that no cybercriminal is truly anonymous, and it sends fear into the underground. However, history warns us: takedowns often lead to temporary fragmentation before criminals regroup elsewhere. The battle is far from over.
✅ Fact Checker Results:
The arrest occurred on July 22, 2025, in Kyiv, led by French and Ukrainian authorities with Europol.
XSS.is was active since 2013, with over 50,000 users, and offered encrypted messaging, escrow services, and illicit trading.
The administrator allegedly earned €7 million and operated another site, thesecure.biz.
🔮 Prediction:
The dismantling of XSS.is will likely result in a short-term vacuum in the Russian-speaking cybercrime ecosystem. However, cybercriminals will migrate to other platforms or build new ones using decentralized technologies and blockchain-based identities. Expect a surge in smaller, encrypted, invite-only forums by the end of 2025, with threat actors becoming more elusive and harder to monitor. Law enforcement’s next challenge will be breaking into these tighter, more secure digital enclaves.
