Endurance Ransomware Claims Breach of US Federal Government

WatchGuard discovered BreachForums posts by an actor calling themselves IntelBroker claiming to run the 'Endurance Ransomware' operation and alleging breaches of the U.S. federal government and two retailers; the actor published alleged proof, advertises exfiltrated data for sale on Sellix for ~$900–$1,000, requests Monero payments, communicates via Tox, and has a public 'Endurance-Wiper' GitHub repository that WatchGuard is assessing.
