This brief details the detection of DNS queries targeting commonly abused Remote Monitoring and Management (RMM) or remote access software domains, originating from non-browser processes, which is a common tactic for command and control, persistence, and lateral movement by threat actors.

Attackers are leveraging MSI installers to deploy remote management software (RMM) such as ScreenConnect, Syncro, and VNC, potentially indicating unauthorized access and control over compromised systems.

Detects a suspicious sequence of an MSI installer execution immediately followed by the execution of commonly abused Remote Management Software, potentially indicating unauthorized remote access.

This rule identifies Windows hosts where two or more distinct remote monitoring and management (RMM) or remote-access tool vendors are observed starting processes within the same eight-minute window, potentially indicating compromise, shadow IT, or attacker staging of redundant access.
