Windows Anti-Forensics

The art of data hiding (also known as steganography) is basically storing data in a place where it is not supposed to go. There are numerous techniques to conceal data in different digital file types like Text documents, images, audio and video files. The underlying file system that is used to host operating system files also can be exploited to conceal secret data and other executable files.

Current operating system file structures give us vast possibilities to conceal our data and make it harder to detect. Unfortunately, anyone with malicious intent can also use these techniques to attack our systems.

In this article, we investigate advanced data concealment technique inside Windows NTFS file system. We begin by looking at how the ADS feature of NTFS file system can be exploited to conceal secret data stealthy inside it. This is followed by an investigation into how we might exploit the ADS stream feature to conceal malware and launch deadly attacks against target Windows® machines.
