Despite the fact that iPhone and Android keep on biting off greater parts of smartphone market, BlackBerry fans are still there, in spite of its various peculiarities. I won’t compare multi-touch displays, HD cameras, smart sensors, applications or anything like that. I’d rather talk about BlackBerry Desktop Software.  Yes, it can create backups, restore information from backups, and synchronize with Outlook only, period.  But that’s just not enough… (more…)

Cracking BlackBerry backups is now slower… but still possible, thx to GPU acceleration

If you have read our recent Cracking BlackBerry Backup Passwords article, you should be familiar with encryption implemented in BlackBerry Desktop Software. Just reminding:

In short, standard key-derivation function, PBKDF2, is used in a very strange way, to say the least. Where Apple has used 2’000 iterations in iOS 3.x, and 10’000 iterations in iOS 4.x, BlackBerry uses only one.

So password verification is (was) so fast/simple that we did not care about implementing it on the GPU — modern CPU is able to crack almost 8 million passwords per second (thanks to multi-threading and AES-NI). We would not call that the vulnerability, but still the weak link.

But new versions of BlackBerry Desktop Software have been released reсently (6.0 for Windows and 2.0 for Mac). And as always, there are bad news and there are good news.
