T1063 - Security Software Discovery

Description from ATT&CK

Adversaries may attempt to get a listing of security software, configurations, defensive tools, and sensors that are installed on the system. This may include things such as local firewall rules, anti-virus, and virtualization. These checks may be built into early-stage remote access tools.

Windows

Example commands that can be used to obtain security software information are netsh, reg query with Reg, dir with cmd, and Tasklist, but other indicators of discovery behavior may be more specific to the type of software or security system the adversary is looking for.

Mac

It's becoming more common to see macOS malware perform checks for LittleSnitch and KnockKnock software.
