Researchers disclosed an unpatched NTLM coercion vulnerability in the Windows search: URI handler that allows attackers to steal Net-NTLMv2 hashes via a malicious link or command execution.

Defenders must rely on environmental mitigations like blocking outbound SMB and restricting NTLM traffic to prevent exploitation.
