What it detects

This rule detects a Chromium-based browser started with the remote debugging port flag, a technique the Airstalk malware uses to hijack browser sessions and steal cookies and tokens. Enabling the debugging protocol lets the malware drive the browser and read authenticated state. Detecting this launch surfaces credential and session theft in a suspected supply chain intrusion.
