ATT&CK analytic guidance
DET0499 Behavioral Detection of Fallback or Alternate C2 Channels
AN1376 Analytic 1376
Establishing network connections on uncommon ports or protocols following C2 disruption or blocking. Often executed by processes that typically exhibit no network activity.
AN1377 Analytic 1377
Creation of outbound connections on alternate ports or using covert transport (e.g., ICMP, DNS) from non-network-intensive processes, following known disruption or blocked traffic.
AN1378 Analytic 1378
Outbound fallback traffic from low-profile or background launch agents using unusual protocols or destinations after primary channel inactivity.
AN1379 Analytic 1379
Outbound traffic from host management services or guest-to-host interactions over unusual interfaces (e.g., backdoor API endpoints or external VPN tunnels).

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.
