Blackberry's CEO has already indicated that the company is willing and able to defeat device encryption for law enforcement: "At BlackBerry, we understand, arguably more than any other large tech company, the importance of our privacy commitment to product success and brand value: privacy and security form the crux of everything we do. However, our privacy commitment does not extend to criminals," http://blogs.blackberry.com/2015/12/the-encryption-debate-a-way-forward/ http://blogs.blackberry.com/2015/12/the-encryption-debate-a-... In the same blog he says the company doesn't put backdoors in, but how do they plan in defeating Android's hardware encryption if there isn't one?

Yes, except in this case it appears that the defendant was using PGP on the device, and BB was not involved in the decryption effort at all. So either nation-state compromise of PGP itself (unlikely), or key compromise (more likely). Edit: I wouldn't dismiss compromise of PGP out of hand entirely, even though it sounds crazy. Both the judge and NFI denied the defense the ability to audit the NFI's methods. I can't imagine hamstringing the defense like this if it was a simple case of "your dumbass client left his key in plaintext on the device". So there is a very slight fishy smell, here.

  They probably brute forced his password given a copy of the private key file and didn't want to disclose that method.

  Some of the recent leaked docs point to the NSA having problems with PGP these days, but the rumor back in mid-90s was that they successfully broke it in multiple ways, which lead the Feds to drop the case against Zimmerman. No idea of the validity of this story, but it seems plausible at least: http://kraut.co/2015/02/28/1994-when-the-nsa-loved-pgp/ http://kraut.co/2015/02/28/1994-when-the-nsa-loved-pgp/
