Attackers are exploiting CVE-2026-32202, a zero-click vulnerability in Windows Shell, allowing authentication of victims' systems without user interaction. This vulnerability stems from an incomplete patch for CVE-2026-21510 and has been used by the APT28 group with weaponized LNK files to bypass Windows security. Although Microsoft addressed these vulnerabilities in February 2026, the risk remains as opening a folder with a malicious LNK file can still connect victims' machines to the attacker's server, initiating an NTLM authentication handshake that exposes the victim’s Net-NTLMv2 hash. This affects various versions of Windows 10, 11, and Windows Server. Microsoft released a patch for CVE-2026-32202 on April 14, 2026, but did not label it as actively exploited until more than two weeks later, leaving security teams unaware of its urgency. Organizations are advised to apply the patch and consider blocking outbound SMB traffic to mitigate risks.
