Apple has put a lot of work into making its phones hard to crack, much to the consternation of US law enforcement officials. It’s still not perfect, however, as researchers from John Hopkins University have discovered a flaw that lets attackers intercept and decrypt video and images sent on iMessage. The exploit only works on versions prior to iOS 9, because Apple partially fixed the problem in that version. However, John Hopkins professor Matthew D. Green told the Washington Post that a modified exploit could possibly be developed for iOS 9 versions, provided hackers have skills of a “nation state.”
The hack is pretty simple. The team first created software that emulates an Apple server in order to intercept files. iMessage photos and video only use 64-bit encryption and don’t lock out invaders after multiple attempts to decrypt. That allowed the researchers to “brute force” video and image files and eventually decrypt them. For the full article click here
