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
