Description

Detects the creation of potentially malicious script and executable files in Windows startup folders, which is a common persistence technique used by threat actors. These files (.ps1, .vbs, .js, .bat, etc.) are automatically executed when a user logs in, making the Startup folder an attractive target for attackers. This technique is frequently observed in malvertising campaigns and malware distribution where attackers attempt to maintain long-term access to compromised systems.
