SHINYHUNTERS HACKS CLOP LEAK SITE, THREATENS TO EXTORT RANSOMWARE GANG

Summary from the TLDR InfoSec newsletter

The ShinyHunters ransomware gang hacked the Clop ransomware gang's data leak site on Tor, defaced it, and claimed to have stolen server data and private keys for its onion service. The ShinyHunters claim to have exploited an unauthenticated file upload vulnerability in Grav CMS to breach the site. This appears to be the latest escalation in an ongoing feud between the two ransomware gangs.
