What it detects

This rule detects execution of brightmetricagent.exe, a remote support agent binary abused during Volt Typhoon intrusions for persistent access. Because this specific agent is uncommon in most enterprise fleets and was used as attacker tooling, its presence on endpoints should be verified against sanctioned software inventories.
