Connect Wise Quietly Patches Flaw That Helps Phishers
Summary: ConnectWise warned MSP customers about a sophisticated phishing campaign that can give attackers remote control of user systems, weeks after it quietly patched a flaw researcher Ken Pyle reported in October. Pyle showed that ConnectWise Control client executables are generated from client-controlled parameters, letting an attacker craft a ConnectWise-signed download link that bounces the connection through the attacker's own Control server and bypasses network rules that only allow remote assistance from the MSP's networks.
What's compelling: The link a victim clicks is signed by ConnectWise and ends in screenconnect.com, so the standard advice to check the domain and trust the sender offers no protection; ConnectWise rated the issue minimal and shipped the fix in its 22.8 and 22.9 builds without a security advisory.
