relay attacks

About this tag
Relay attacks, particularly NTLM relay attacks, remain a significant threat to Active Directory environments in 2025. Despite years of security improvements, many enterprise domains are still susceptible, enabling lateral movement and privilege escalation. Recent incidents show attackers exploiting NTLM vulnerabilities like CVE-2025-24054 to steal hashes via phishing campaigns, targeting government and private sectors. Microsoft's Patch Tuesday updates address these issues, but organizations must enforce mitigations such as disabling NTLM or using Extended Protection for Authentication. Understanding and defending against relay attacks is crucial for IT security teams managing Windows and Microsoft 365 environments.
