The drive was totally done with. It wouldn't boot up at all and no data could be accessed from it.

 

After some quick online research, I decided to put the drive in a ziplock bag, and I threw it in the freezer overnight. The next day I removed it from the freezer and I immediately hooked it up to a Mac, and I was able to retrieve most of the data that was on the drive. It worked for almost an hour, then it died again, and remained dead for good.

They were able to something like this with Walt Disney's brain and extracted the story lines for two new animated movies and learned the real relationship between Donald Duck and his nephews.

I would say the whole scenario sounds pretty goofy...

The whole point of encrypting the drive is that, in the unfortunate case where a malicious party gets physical access, it would still be very difficult to access the data.

This is a case where a security feature does not fulfill its promise.

Not that strange.

 

This form of attack has been demonstrated as early as 2008 (http://forums.overclockers.com.au/showthread.php?t=655809) as a method to freeze the RAM of a laptop to uncover the whole disk encryption key in memory.   A couple cans of liquid Air was enough to freeze the DRAM and capture the entered (at last boot) the key from memory (accessing the RAM as a raw data device).

Beat me to it also, maybe they needed a better name scheme.

Isn't easier to point a gun to the person and ask the password?

They could manufacture the phone to explode below a threshold temperature. Canadians would have to buy phone muffs to keep from blowing their hands off.

Why bother with the cooler - just wait for it to freeze on its own... (rimshot)

Of course, the freezing RAM method would work on any device... including iPhones.

 

OTOH, perhaps Apple has anti-freeze protection already built in by accident:

Meanwhile, a much more common problem AI has yet to report:

 

Apple finally fixes App Store flaw by turning on encryption

Company moves to protect its iOS customers from security and privacy attacks over Wi-Fi by turning on encryption, at least half a year after being alerted to the problem.
