Net-NTLMv2 disclosure via auto-parsed LNK path

Published Apr 14, 2026 · Updated Apr 14, 2026

Authentication coercion in Microsoft Windows Shell allows remote attackers to disclose Net-NTLMv2 material through a crafted LNK file. Explorer parses the LNK's LinkTargetIDList and resolves an embedded UNC Control Panel path before trust verification, initiating SMB authentication. A target must browse a folder containing the LNK; no click is required, and the disclosed challenge-response material supports relay or offline cracking.
