    Microsoft Windows NTLMv2 Hash Disclosure Spoofing Vulnerability — Microsoft Windows contains an NTLMv2 hash spoofing vulnerability that could result in disclosing a user's NTLMv2 hash to an attacker via a file open operation. The attacker could then leverage this hash to impersonate that user. Listed in the CISA KEV catalog (added 2024-11-12) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~82%. Treat it as real and prioritize remediation over triage.
