What it detects

This rule detects execution of attacker-staged binaries with names such as FunnyApp.exe, RedSun.exe, or z.exe from user Downloads or Pictures folders. These payloads were staged during a Huntress-investigated intrusion following VPN access and used to advance the attack, including bring-your-own-vulnerable-driver activity. Execution of these specific filenames from staging directories indicates deployment of hands-on-keyboard tooling.
