DET0404 Detect Winlogon Helper DLL Abuse via Registry and Process Artifacts on Windows
AN1133 Analytic 1133
Monitor Windows Registry modifications to Winlogon keys (Shell, Userinit, Notify) that introduce new executable or DLL paths. Correlate these changes with subsequent DLL loading, image loads, or process creation originating from winlogon.exe or userinit.exe. Abnormal child process lineage or unauthorized binaries in C:\Windows\System32 may indicate abuse.

Threat actor context
These are explicit actor-to-technique associations in the existing Threat Matrix snapshot, not attribution of an event or proof that a detector identifies the actor. No tool-to-actor relationship is inferred.
Existing anomaly research
Pinned research references. No browser attack runner, live simulation result or validated detector is asserted. Source mappings and validation limits are preserved. ATT&CK / Atomic provenance · Detection provenance.
