Smartphone Forensics: Cracking BlackBerry Backup Passwords

Thursday, September 30th, 2010

BlackBerry dominates the North American smartphone market, enjoying almost 40 per cent market share. A 20 per cent worldwide market share isn’t exactly a bad thing, too. The total subscriber base for the BlackBerry platform is more than 50 million users.

Today, we are proud to present world’s first tool to facilitate forensic analysis of BlackBerry devices by enabling access to protected data stored on users’ BlackBerries.

One of the reasons of BlackBerry high popularity is its ultimate security. It was the only commercial mobile communication device that was ever allowed to a US president: Barack Obama has won the privilege to keep his prized BlackBerry despite resistance from NSA. (On a similar note, Russian president Dmitry Medvedev was handed an iPhone 4 a day before its official release by no one but Steve Jobs himself. No worries, we crack those, too).

Mind your passwords, make them different

XKCD posted quite nice comics with a reallife problem behind them. It is very likely that some Web-services do as described, either sell such info to third parties or use it for evil purposes. Our recommendation is if you cannot trust some of the websites, choose another unique password for them. It would be even wiser if you had different passwords for all websites you visit. Some even unimportant websites can aslo be cracked and even if they (better to say your data stored there) have no value at all, your password, can be tried for Facebook or LinkedIn, hopefully in vain. :)

iPhone 4 Performance

Wednesday, September 15th, 2010

Finally, we’ve got our first iPhone 4 in office. And what was the first thing we did with it? Yes, test its performance to complete table in my previous post.

This brand-new iPhone 4 is capable of doing 1.4 millions MD5 iterations per second, about 35% more than iPhone 3GS.

I haven’t found any information on iPhone 4CPU clock frequency, but if we assume that it uses same chip as iPad (which seems to be the case), then exhibited performance corresponds to roughly 775 MHz.
