![]() Like TrueCrypt, it was used by Mr Snowden. That is what happened to LavaBit, an e-mail provider which promised to encrypt its users’ messages. But they have not.Īnother, more paranoid interpretation is that the developers have been tapped on the shoulder by the Men in Black. But SourceForge, a repository for open-source software which hosts TrueCrypt, reported that it had noticed nothing unusual: “We see no indicator of account compromise current usage is consistent with past usage.” Had they been hacked, the development team might have been expected to say so in public. One theory is that TrueCrypt’s developers have simply been hacked, and that the message is a piece of mischief-making. ![]() After Mr Snowden’s revelations, those with a serious need for TrueCrypt would be reluctant to trust BitLocker. But, as security researchers were quick to point out, this is a strange piece of advice. Newer versions of Windows come with their own disk-encryption program, BitLocker, and the message recommends using that instead. TrueCrypt offered a short explanation: the end of Microsoft’s support for its ancient Windows XP operating system. Mr Snowden’s revelations had boosted its popularity still further. It is open-source, meaning its code is freely available for anyone to look at. TrueCrypt had been in development (by a group of anonymous programmers) for ten years and was popular with everyone from security-conscious lawyers to journalists with sources to protect and dissidents in countries where too much complaining can land you in prison or worse. The announcement caused plenty of raised eyebrows. It exists only to help users recover encrypted files. A new version was released that was incapable of encrypting anything. It warned that “Using TrueCrypt is not secure as it may contain unfixed security issues”. On May 29th TrueCrypt’s website was updated with a brief, cryptic message. As always, encryption is no use without proper pre-boot authentication.Or that is what it used to do. This is, to my knowledge, the first commercial implementation (or should that be exploitation?) of the Firewire memory attack, and should be considered by anyone intending to use products such as Bitlocker or Truecrypt, without making sure they implement them in a way which prevents this kind of exploitation. Click Next – Passware will now decrypt the disk image. Select the memory image file, and the disk image fileĤ. Click “Recover Hard Disk Passwords” within the Passware Kitģ. ![]() Create disk images using tools such as Encaseġ. Boot the forensic computer off the USB stick from step 1 to capture the imageĤ. Connect the target computer to the forensic computer using a Firewire cableģ. Create the Firewire memory imager from the Passware Kit on a USB StickĢ. Step 1 – capture a forensic memory image and disk imagesġ. As to how to do it, well they have implemented the exploit in a very neat and usable way: A feisty California company has released a version of their forensic software which will decrypt Bitlocker and TrueCrypt protected hard disks via the classic Firewire vulnerabilities.Ī full write-up can be found on the Passware site, but simply, given a machine that’s running, but has encrypted drives (for example one using Bitlocker in TPM-only mode, or a machine which is suspended, not hibernated). ![]() Following on from my post “10 Things You Don’t Want To Know About Bitlocker”, “TPM Undressed” and “Firewire Attacks Revisited” it recently came to my attention that Passware, Inc. ![]()
