What it detects

This rule detects the AteraAgent remote monitoring binary launched with init-settings and an embedded integrator or company key, a command line used to silently onboard a host into an attacker-controlled Atera tenant. Adversaries abuse legitimate RMM agents like Atera for persistent remote access and command execution, so unattended agent onboarding outside sanctioned IT deployment is a meaningful signal.
