About this tag
NTLMv2 is a legacy Windows authentication protocol that remains a frequent target for security vulnerabilities. Recent Microsoft patches address improper authentication and privilege elevation flaws in NTLM, such as CVE-2025-53778 and CVE-2025-54918, which allow authenticated attackers to elevate privileges over a network. These issues are part of a broader trend of NTLM-related incidents, including zero-day exploits and hash-disclosure weaknesses. Administrators are urged to apply patches promptly and harden authentication configurations to mitigate risks. The tag covers discussions on Patch Tuesday updates, vulnerability disclosures, and best practices for securing NTLMv2 in enterprise environments.
