Less than a month ago, we updated our Elcomsoft Phone Password Breaker tool with the ability to recover master passwords for BlackBerry Password Keeper and BlackBerry Wallet. I have blogged about that and promised the “next big thing” for BlackBerry forensics to be coming soon. The day arrived.

SANS Information Security Reading Room has recently publicized a whitepaper about iOS security where they mentioned our software – Elcomsoft iOS Forensic Toolkit – in a section about encryption. Kiel Thomas, the author of the whitepaper, explained one more time the main principles of iOS 4 encryption, which became stronger in comparison with iOS 3.x and how our toolkit can bypass new strong algorithms.
In its next part about iTunes Backups Kiel touches upon Elcomsoft Phone Password Breaker which virtually crunches backup passwords at speed of 35000 passwords per second (with AMD Radeon HD 5970) using both brute force and dictionary attacks, here are some benchmarks.
It seems the paper does not miss out on any nuance about iOS 4 and provides practical advice to either avoid or prevent from the depressing outcomes, such as loss of data. Closer to the end of the paper you will also find several sagacious tips for using the devices within organizations, including passcode management, a so called “first line of defense” which according Kiel’s view “can be matched to existing password policies”, however he inclines to use passwords instead of 4 digit passcodes.
And in conclusion the author discovers that smartphone and tablet security measurements resemble the ones of laptops, because they all belong to mobile devices. Find out more details in the source itself: http://www.sans.org/reading_room/whitepapers/pda/security-implications-ios_33724
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…)
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.
