A cybercrime group with links to the RansomHub ransomware has been observed using a new tool designed to terminate endpoint detection and response (EDR) software on compromised hosts, joining the likes of other similar programs like AuKill (aka AvNeutralizer) and Terminator .

Scattered Spider is the designation given to a threat actor that's known for its sophisticated social engineering schemes to breach targets and establish persistence for follow-on exploitation and data theft.

"RansomHub is a ransomware-as-a-service (RaaS) payload used by more and mor...
