What it detects
This rule detects tasklist output piped into findstr to search for antivirus process names such as Bitdefender, ESET, Quick Heal and Sophos. The Lumma infostealer enumerates running security products this way to fingerprint defenses and adjust its behavior before credential theft.
Reporting behind it
