DET0221 Behavioral Detection Strategy for T1123 Audio Capture Across Windows, Linux, macOS
AN0619 Analytic 0619
Unusual or unauthorized processes accessing microphone APIs (e.g., winmm.dll, avrt.dll) followed by audio file writes to user-accessible or temp directories.
AN0620 Analytic 0620
Processes accessing ALSA/PulseAudio devices or executing audio capture binaries like 'arecord', followed by file creation or suspicious child process spawning.
AN0621 Analytic 0621
Processes invoking AVFoundation or CoreAudio frameworks, accessing input devices via TCC logs or Unified Logs, followed by writing AIFF/WAV/MP3 files to disk.

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.

Exact source tags are not semantic relevance verdicts. Review actual rule conditions and observation points; imported rules are not backend-compiled or live-validated.
Pinned research references. No browser attack runner or production-validated detector is asserted. Imported procedures remain unvalidated; any bounded lab evidence has its own scope. ATT&CK / Atomic provenance · Detection provenance.
