ScreenConnect Attacks Target at Least 288 Endpoints Across 48 Organizations With Rogue Clients
AI-summarised brief · reviewed before publication
ConnectWise disabled five third‑party extensions in partner environments after reports of unauthorized access. The company confirmed no evidence of a ScreenConnect software flaw and identified about 400 partner sites with the extensions installed. Cybersecurity firm Huntress traced attackers using compromised credentials or hijacked sessions to push rogue ScreenConnect clients to at least 288 endpoints across 48 organizations. The malware, named SCKit, establishes persistent remote access, installs a second attacker‑controlled client, and creates a relay trap to intercept session cookies. The attack spreads in a worm‑like two‑step process from infected endpoints to technicians and then to other endpoints.
