Detects instances where internal devices access the 3BB sales portal (agent.3bb.co.th) while demonstrating signs of compromise. The rule correlates the portal access with recent network activity involving identified MeshCentral attacker infrastructure (ayuthayatech.com or 92.63.180.133) and further filters for behavioral anomalies such as off-hours access, the use of non-standard browser processes, or the use of unexpected service accounts.
Detects SSH persistence planted during the Red Heron campaign: authorized_keys file writes under a .ssh folder, correlated with process command lines referencing authorized_keys and the operator's observed key comment naming pattern (backdoor / root-shell).
Detects access to Gitea secrets and configuration (app.ini, JWT secrets, SSH host keys, deploy keys) via file writes/renames or process command lines referencing those paths alongside Gitea, matching the secret-extraction tradecraft observed in the Red Heron campaign.

Detects network requests to the Gitea Prometheus metrics API that contain 'k=' and 'x=' query parameters, a pattern indicative of a C2 command channel disguised as legitimate telemetry traffic.

Detects HTTP POST requests to a Gitea repository's diffpatch API endpoint whose body contains both a real git diff header and the malicious 'hooks/post-index-change' file path used by the CVE-2026-60004 exploit chain to plant an executable Git hook via an add/add merge collision.

Detects the suspicious registration of a Cloud Filter provider callback using staging paths and naming conventions associated with the ShieldCrash (CVE-2026-69414) exploit. The rule monitors DeviceEvents for cloud provider activity that originates from unsigned or untrusted binaries, excluding known-legitimate cloud synchronization clients.
