However if you are able to reach an unlock computer with an encrupted volume mounted (the main hard disk or an USB drive, an specific file), with the use of this tool you could bypass the barrier.Symantec Encryption Desktop Professional 10.4.1 + Keymaker-CORE | 124.76 MB/Symantec PGP Command Line 10.4.1 (Win/Mac/Lnx) + Keymaker-CORE | 146.21 MB So IMHO, the only remaining chance it is performing a Cold Boot Attack in order to get the memory dump In that case, it is point out to get the memory dump by the FireWire attack, but all the documentation found in the net is quite all (2008-2009), and it appears that latest operating system are not vulnerable to these kind of issues, at least after installing the latest service packs available. If the computer is suspended with password, you are not able to dump the RAM as you are not able to execute programs.

if you have full disk encryption and the system in hibernate, it is not possible to get not encrypter RAW data. Reply DeleteĪfter reading the article, the only way to bypass the ecryptation system is getting a memory dump or the pagefile.sys / hybernation file after mounting an encrypted volume. And we do find all the available keys, not just for the disk (but all others that also reside in memory). For PGP, you can even select what particular keys to search for (if you know the encryption algorythm and key length, searching is much faster). TPM (or smartcard) only affects the authentication, but we don't care how the encryption keys are being generated - we catch them at the later stage.Ĥ. We should definitely put some research there (as well as for USB flash drives with built-in encryption).ģ.
In any case, that's a good challenge for forensics, obviously. There is a chance that the same method would be applicable, but not 100% sure, sorry.
To be honest, we have not investigated such (hardware-based) HDD encryption yet. For PGP, we just looked at the soorces and used them a little bit for TrueCrypt - more intensively.Ģ. For BitLocker, it is copletely reverse-enineering. Sorry for delay answering your questions, it's been a very hard week.ġ. Vladimir Katalov 22 December 2012 at 14:26 If you're concerned of a targeted attack involving a combination of malware and theft, or a breaking&entering to physically insert a firewire device, then you need better comprehensive security than just an off-the-shelf encryption product.ĭisclaimer: I used to work for PGP and have pretty intimate knowledge of how these things work. This does raise the question: as an attacker, if I already have access to the system in a decrypted state (to exfiltrate the hibernation file), why not just copy the data I'm looking for? Seems a lot easier than extracting the hibernation file, then going back and stealing the laptop. THAT is the primary threat model which people buy disk encryption products to protect against.

This could be due to a trojan that exfiltrates the hibernation file to a command and control site, or by inserting a rogue firewire device when the user steps away from the system.Įither way, this product does not let you steal some random person's hibernated laptop in an airport and expect to crack the encryption. Products like Elcommsoft require access to the system when it's already in a running (authenticated) state to get the hibernation file or memory dump.

The boot loader doesn't "read" the hibernation file, that's all handled through the Windows boot process (post secure boot loader and authentication).
#Symantec encryption desktop bypass driver
Once the encryption product's Windows-based disk driver gets loaded, there's a hand-off and in-memory decryption gets performed by the 32-bit (or 64-bit) driver.
Once the bootloader authenticates the user, it hooks the BIOS (or UEFI) file I/O system to insert an on-the-fly decryption routine then starts the Windows boot process. If the passphrase is wrong, the disk key can't be decrypted. The boot loader that allows entry of the passphrase is the only readable section of the drive, and contains no cleartext confidential information.even the AES key is encrypted to a key which is dynamically generated based on a conversion of the user's passphrase. The hibernation file is completely encrypted, and can only be decrypted after the user enters his pre-boot passphrase.
