Metasploit Anti-Forensics Project

The Metasploit Anti-Forensics Project, originally created by our team and now maintained by the community, seeks to develop tools and techniques for removing forensic evidence from computer systems.  This project includes a number of tools, including Timestomp, Slacker, and SAM Juicer, many of which have been integrated in the Metasploit Framework.

Metasploit Anti-Forensics Project Tools

Slacker allows you to hide data in the slack space of NTFS. This slack space is created when a file system allocates space for a file to be written, it will typically allocate more space than it actually uses. The unused space is called slack space and perfect data-hiding grounds for the hacker.

The Sam Juicer runs over a memory/LSASS channel to dump password hashes on a Windows system without leaving any sort of trace or signature on the disk or registry.

The Windows API does not properly translate the low 64-bit time values stored on disk into human readable format, and displays no information instead. Although this is not a security vulnerability in itself, it adversely affects third-party applications that rely upon the Windows API to perform the translation.
