Disk encryption can be beaten
"A new hack allowing attackers to take peoples files even after encryption."

It has been proven that RAM can take some time spanning from seconds to minutes before losing its data. This allows the attacker to take the data from the memory or alternatively take the RAM module.
Also, if the RAM module is kept cool, it will retain its data for a much longer period of time. For example, if you blow canned air onto the module, it will hold memory for a few more minutes; if you keep it in liquid nitrogen then the data could be held for days. This gives the attacker a lot more time.
We also have a picture of what happens to the data on the RAM after the power has been turned off.
As you can see, the data slowly fades away. The right hand side is after a loss power for 5 minutes and the left is after 5 seconds. Learn a new thing every day here at OC3D.
