FROST: Forensic Recovery Of Scrambled Telephones

A ready to go cold boot attack for a Galaxy Nexus!
Your Android PIN does not protect you.

We present FROST, a tool set that supports the forensic recovery of scrambled telephones. To this end we perform cold boot attacks against Android smartphones and retrieve disk encryption keys from RAM. We show that cold boot attacks against Android phones are generally possible for the first time, and we perform our attacks practically against Galaxy Nexus devices from Samsung. To break disk encryption, the bootloader must be unlocked before the attack because scrambled user partitions are wiped during unlocking. However, we show that cold boot attacks are more generic and allow to retrieve sensitive information, such as contact lists, visited web sites, and photos, directly from RAM, even though the bootloader is locked.

Side Channel Attacks

An interesting read on side channel attacks:

“The second story was about USB devices. Basically, they plugged a very precise voltmeter into an USB port and started recording the very small variations between 4.999V and 5V. With the same assembly-test-program-pattern-matching approach, they broke RSA again.” Link.
