Name
Potential Mark-of-the-Web Bypass Attempt via Registry Modification
Author
Swachchhanda Shrawan Poudel (Nextron Systems)
Description
Detects a registry modification that bypasses the Mark-of-the-Web (MOTW) security
zone check, suppressing the warning dialog normally shown when executing files
downloaded from the internet. The setting persists across the user session and
affects all shell-launched processes, enabling malware to silently execute
internet-origin payloads without user confirmation.
