CVE-2023-24880: Windows SmartScreen Security Feature Bypass Vulnerability
What is the relationship between Mark of the Web and Windows SmartScreen?
When you download a file from the internet, Windows adds the zone identifier or Mark of the Web as an NTFS stream to the file. So, when you run the file, Windows SmartScreen checks if there is a zone identifier Alternate Data Stream (ADS) attached to the file. If the ADS indicates ZoneId=3 which means that the file was downloaded from the internet, the SmartScreen does a reputation check.
