Ukraine Cracks Down on Cybercrime: Arrest and Seizure of XSS.IS
Early this morning, significant news emerged from Ukraine regarding a high-profile cybercrime operation. On July 22, 2025, authorities arrested an individual believed to be the administrator of XSS.IS, one of the most notorious cybercrime forums globally. This operation was bolstered by collaboration between Europol and French law enforcement agencies. As reported by Hackread.com, the forum has also been seized, marking a considerable win in the battle against cybercrime.
Seizure Notice on XSS.IS
Visitors attempting to access XSS.IS are now met with a seizure notice stating, “This domain has been seized by la Brigade de Lutte Contre la Cybercriminalité with assistance from the SBU Cyber Department.” The SBU Cyber Department refers to Ukraine’s Security Service’s unit focused on cyber threats, while BL2C is a specialized branch of the French police dedicated to combating cybercriminal activities.
Status of Dark Web and Clearnet Domains
As of now, the main domain of XSS.IS displays the seizure notice, but its dark web domain and another clearnet mirror (XSS.AS) are returning a “504 Gateway Timeout” error. Interestingly, the associated Telegram channel for XSS.IS, linked directly to the administrator, remains active and has been marked as “recently seen.” It’s still unclear if law enforcement has control over this channel, suggesting that some elements of the operation may remain intact despite the arrest.
The History of XSS.IS
XSS.IS originally launched back in 2004, initially branded as DaMaGeLaB, a well-known Russian-language hacking community. After facing closure in December 2017 due to the arrest of one of its administrators, Sergey Yarets (known as “Ar3s”), the forum re-emerged in late 2018 under its current name, aptly reflecting the cross-site scripting vulnerability that hackers often exploit.
The rebranding aimed to dissociate the forum from its previous connections to law enforcement while providing a more modern identity appealing to its target audience. Over the years, there have been suspicions that Russian intelligence agencies might have some form of backing for XSS.IS; however, the apprehended administrator was located in Ukraine. The national identity of the suspect remains unconfirmed.
Impact on the Cybercrime Landscape
The seizure of XSS.IS constitutes a significant blow to the international cybercrime ecosystem. With over 50,000 registered users, the forum had strict membership requirements, often demanding fees to deter spam. XSS.IS was a marketplace for various illicit goods, including hijacked access, malware, and stolen data. The forum generated millions in revenue through advertising and service fees, making it a key player in cybercrime operations.
According to a press release from Europol, the authorities not only dismantled the forum but have also acquired extensive user data. This information is set to be analyzed meticulously, assisting in ongoing operations aimed at tracking and prosecuting cybercriminals globally.
Conclusion: The Ongoing War Against Cybercrime
The events surrounding XSS.IS send a clear message: involvement in organized cybercrime is increasingly unsafe. Authorities, working collaboratively across borders, have shown their commitment to dismantling major platforms that facilitate criminal activities online. As law enforcement enhances its strategies and technologies, it’s evident that no cybercriminal operation, regardless of its complexity, is immune to law enforcement intervention.
With every action against such platforms, the possibility of long-term repercussions looms. Cybercriminals may find themselves facing a more challenging environment as authorities ramp up efforts to safeguard digital spaces globally.
