Script Execution from Mounted Virtual Disk
Detects the execution of script interpreters (wscript.exe, cscript.exe, cmd.exe, powershell.exe) where the script file being executed resides on a newly mounted virtual disk volume (VHD, ISO, etc.). This technique is used by malware, such as in the Dead#Vax campaign, to bypass the Mark-of-the-Web (MotW) security feature, allowing malicious files inside the container to execute without standard untrusted file warnings.
