The ShinyHunters extortion gang breached the Clop (aka Cl0p) ransomware operation's data leak site, defacing the Tor site and allegedly stealing server data and the private keys for its onion service.

The attack began Friday night when ShinyHunters exploited what they claim is an unauthenticated file upload vulnerability in Grav CMS, which they used to upload a small text file to Clop's site.

The small text file contained a message from the threat actors to the Clop ransomware gang, warning not to threaten them and including a link to ShinyHunter's own data leak site.

"THIS SITE HAS BEEN PWN3D BY SHINYHUNTERES #Skids10p - Maybe don't try to threaten us next time," read the uploaded file.
