System Service Discovery

Adversaries may try to gather information about registered local system services. Adversaries may obtain information about services using tools as well as OS utility commands such as sc query, tasklist /svc, systemctl --type=service, and net start. Adversaries may also gather information about schedule tasks via commands such as schtasks on Windows or crontab -l on Linux and macOS.[1][2][3][4]

Adversaries may use the information from System Service Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.
