What it detects

This rule detects AteraAgent executed with IntegratorLogin and CompanyId parameters which perform a silent unattended enrollment of the Atera remote monitoring agent. Adversaries in phishing campaigns delivering RMM tools use these switches to covertly onboard victim hosts into an attacker controlled Atera tenant. Detecting this command line surfaces unauthorized remote access tool deployment.
