Cybercrime forum XSS is back online on its mirror and dark web domains just one day after seizure and admin arrest, but questions about its full return remain unanswered.

On July 23, 2025, as reported by Hackread.com, the cybercrime community lost one of its oldest and most notorious forums, XSS, after law enforcement authorities seized the site and arrested its suspected administrator in Ukraine.

The arrest led to the seizure of the forum’s main domain, XSS.IS, which now displays a notice from Europol, French and Ukrainian authorities. However, the forum’s dark web (.onion) and mirror domains did not show a seizure notice but instead returned a 504 Gateway Timeout error.

As of July 24, Hackread.com can confirm that the XSS forum is back online via both its mirror and .onion domains. While it is unclear whether this is a honeypot set up by authorities, one of the forum’s administrators has posted claiming the infrastructure was not affected by the seizure and that a replacement is in progress.
