Description
The following analytic detects instances where a Windows Chromium-based browser process is launched with the `--disable-popup-blocking` flag. This flag is typically used to bypass the browser’s built-in pop-up protections, allowing automatic execution of pop-ups or redirects without user interaction. While legitimate in some testing or automation scenarios, its presence on endpoints, particularly when combined with other automation or concealment flags, may indicate attempts by malicious actors to execute web-based content stealthily or evade user interaction controls, representing a potential security risk that warrants investigation.
