What it detects

This rule detects creation of files matching the ADE_ prefix text file pattern in the local AppData Temp directory, the naming scheme BunnyLoader uses to stage captured keystrokes before exfiltration. Writing keylog output under this predictable path reflects the loader collection module in operation, marking active credential and data theft.
