ATT&CK analytic guidance
DET0472 Detect Malicious Password Filter DLL Registration
AN1303 Analytic 1303
Detects suspicious registration of new password filter DLLs into the authentication process. Correlates registry modifications to LSASS Notification Packages with subsequent DLL creation and loading events. Observes anomalous file placement of DLLs in system directories followed by LSASS loading the new filter during logon/password change activity.
