CHIPSEC: Platform Security Assessment Framework
CHIPSEC is a framework for analyzing the security of PC platforms including hardware, system firmware (BIOS/UEFI), and platform components. It includes a security test suite, tools for accessing various low level interfaces, and forensic capabilities. It can be run on Windows, Linux, Mac OS X and UEFI shell. Instructions for installing and using CHIPSEC can be found in the manual.
NOTE: This software is for security testing purposes. Use at your own risk. Read WARNING.txt before using.
First version of CHIPSEC was released in March 2014: Announcement at CanSecWest 2014
