BitB Malware Delivery - Browser Process Creates Installer in User Folders
This rule monitors for the creation of .exe or .msi files within common user-writable directories (Downloads, Temp, AppData) initiated by web browser processes (Chrome, Edge, Firefox, Brave). This behavior is often indicative of drive-by downloads or users interacting with malicious web content that delivers installers to the host.
