Important Detection 2026: Pass-the-Hash Lateral Movement Authentication
Detects anomalous lateral movement behavior characterized by an account performing multiple NTLM authentication events (Logon Type 3) across distinct hosts within a short time window, specifically where Kerberos pre-authentication is absent. This pattern is frequently observed in Pass-the-Hash (PtH) attacks where attackers utilize stolen NTLM hashes to move laterally.
