So far, in this new blog, I’ve been mostly focusing on open source tools and open source operating systems, so I’ve not focused on MITRE’s Windows-centric non-open source tool, Copernicus. But the tool is extremely powerful, and deserves more attention.
“Copernicus is the first tool to provide BIOS configuration management and integrity checking capabilities throughout an enterprise. The tool is implemented as a kernel driver that creates a file containing the BIOS dump and a file containing the raw configuration information. When deployed in enterprise environments, scripts can send the raw BIOS dump and configuration information to a server for post-processing. This processing can indicate whether a given BIOS differs from an expected baseline, and it can also indicate whether the BIOS or the computer’s System Management RAM (where some code loaded by BIOS continues running after boot).”
An excerpt from a G+ post in 2013 from Dragos Ruiu on Copernicus:
“IMHO Copernicus BIOS verification tool, is one of the most important new security tools in recent history. We’ve already found some persistent BIOS malware that survives re-flashing with it.”
I wish it were available for Linux, not just for Windows, so I could use it! And I wish it were open source (alas, all security tools are not): trusting any native kernel driver on your system, or especially to deploy to all systems in you enterprise, whether it is natively installed or from another boot media, has issues. I hope licensees from MITRE have the option to review the code and compile it themselves.
[Intel’s CHIPSEC also has some similar features. When run as an OS-present tool — instead of a live-boot or UEFI Shell booted — CHIPSEC also includes a native driver on Windows, and on Linux. With CHIPSEC, the kernel driver sources are provided.]
If you have Windows-based enterprise, you should investigate out Copernicus.
Windows-centric code aside, Copernicus distribution includes bios_diff.py, which works on Linux. This is a wonderful tool.
Even if you don’t care about Windows, you should study the Copernicus research, is it amazing.
Two of the creators of Copernicus have left MITRE and have started LegbaCore. Their last talk on using Copernicus at RSA conference last month was excellent, talking about using Copernicus usage in enterprises.
