ATT&CK analytic guidance
DET0178 Behavioral Detection of Unauthorized VNC Remote Control Sessions
AN0504 Analytic 0504
Detection of VNC service or executable starting unexpectedly, followed by user session creation and interactive desktop activity (mouse/keyboard simulation).
AN0505 Analytic 0505
Spawning of VNC-related processes (e.g., `x11vnc`, `vncserver`) coupled with authentication logs and port listening behavior on TCP 5900.
AN0506 Analytic 0506
Detection of VNC-based remote control via `screensharingd` activity in Unified Logs along with concurrent remote login activity or suspicious user interaction.

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.
