What it detects

This rule detects a Chromium-based browser launched with a remote debugging port or pipe argument, a technique used by EddieStealer and similar infostealers to drive the browser over the DevTools protocol and extract saved passwords and cookies. Remote debugging flags are rarely set by end users and indicate automated browser credential theft.
