Disk Encryption Easily Cracked, Researchers Find

“The disk encryption technology used to secure the data in your
Windows, Apple and Linux laptops can be easily circumvented,
according to new research out of Princeton University.

“The flaw in this approach, the researchers say, is that data
previously thought to disappear immediately from dynamic RAM (DRAM)
actually takes its time to dissolve, leaving the data on the
computer vulnerable to thievery regardless of whether the laptop is
on or off. That’s because the disk encryption key, unlocked via a
