Attack on Windows BitLocker.

Quote:
Fraunhofer SIT has presented a method for discovering the BitLocker drive encryption PIN under Windows. The method even works where TPM is used to protect the boot process. The trick? An attacker with access to the target computer simply boots from a USB flash drive and replaces the BitLocker bootloader with a substitute bootloader which mimics the BitLocker PIN query process but saves the PINs entered by the user to disk in unencrypted form.

Uh, once again this is not a "crack" of or even an "attack" on bitlocker. It is a tried and true "fake UI" attack. You would have to steal the computer, modify it, put it back in the users hands, then resteal it later for this to work. That kind of thing actually works on the web but is pretty far fetched for physical attack. Heck, if you have THAT MUCH access to the machine, just put a "spy camera" over the users shoulder and tape everything he type in in a day!

Bitlocker is there to protect you drive if it gets stolen and as such it still works explicitly.

If someone has that much acess ot your computer then you have no hope, they can put anything on it and that goes for any OS past present and for the forseeable future untill total lockdown "trusted computing" ever takes effect, (which it probably won't due to across the board resistance and general unworkability of it)

The thread isn't BS but Fraunhofer is a bit.

It may actually be more interesting the reason WHY it takes so much work to steal the password. Normally you would just root the machine (generally ewasy to do on any os on most machines) or socially engineer the user to install a program as root and install a lower keyboard filter and record everything the user types. But I believe that the ability to install a keyboard filter has been removed from 7 thus requiring much more complex methods of stealing the password.

So that's a pretty big win for Windows 7 right there.

If that's the best solution for "thwarting bitlocker" that they come up with then bitlocker is perfectly safe, secure and performing the job it was meant to.

They got it. It is $795. So much for secure bio-metrics for civilians. BitLocker would protect against information theft from 95% of the population though...
