Cryogenically frozen RAM bypasses all disk encryption methods

This is a very savvy exploit, according to the video and article the conventional wisdom of when you turn the computer off, the active volatile RAM is erased. However, it seems, conventional wisdom has to elaborate a bit more on the details of precisely how soon that data within the RAM disintegrates.

Apparently the "data" within the RAM slowly fades away when the power is cut, giving a window of opportunity to attack and crack any encryption on the hard-drive, by making a copy of the encryption key.

While no exotic equipment is required for this hack, software that reads the RAM may be required to implement correctly. SOftware of this nature should be readily available on the Internet. One thing is certain, there is always a way around security and this is a proof of concept video.

Check it out.

Enjoy.

Knoppix on a USB

Check this link out. Knoppix on USB thumb-drives are fully bootable and operational computer systems that kick arse. This makes analyzing a new machine easier and less prone to mss-analysis when analyzing code from a compromised operating system on the machine.

Since thumb-drives are nicer than bootable CDs, less cumbersome and re-writable and now have insane memory capacity. I would put this on a 8 gig thumb-drive, 2 gigs for the Operating System (more than what it needs) and 6 gigs for "everything else". I guess I will always carry a CD-R just in case.

We are going to build Android development USBs on Knoppix memory-sticks, with full encryption.
