What it detects

This rule detects HTTP requests to an All-in-1.php endpoint carrying user and password query parameters characteristic of the GTFire phishing scheme credential harvesting kit. GTFire lures victims through translate.goog and web.app redirect hops before submitting stolen credentials via crafted GET parameters. Surfacing this traffic reveals active phishing credential theft against organization users.
