Planetbeing Technical Data Reveals Evasi0n

The news of the week was undoubtedly the release of iOS 6.1 Untethered Jailbreak . Sites like CBS and DaringFireball, not usually cover the news about the Jailbreak, are launching multiple items on it.

There seems to be consensus and everybody is quite impressed with the technical aspects of evasi0n and the whole team behind this Jailbreak. And the truth is no shortage of reasons. Let's see an interview conducted by Forbes one of those responsible for this Jailbreak, Planetbeing.

 Planetbeing Revela los Datos T├ęcnicos de Evasi0n

Planetbeing reveals the complicated methods they use to get the Jailbreak

In the conversation, David Wang (planetbeing) explains that the hack exploits evasi0n at least five errors in the code of iOS 6. And he points out, as a reference, which is a more than Stuxnet malware developed by the NSA to attack nuclear centrifuges.

When Andy Greenberg of Forbes asks Wang guide you through exactly how they work evasi0n, this does not disappoint:

"Evasi0n starts libimobiledevice execution, a program that replaces iTunes for iOS devices communicate via the same protocol used by Apple software. Using this tool, Evasi0n exploits a flaw in the system backups iOS mobile to get access to certain settings that might not normally access, namely a file indicating the time zone of the device. "

The program then inserts a "symbolic link" in the zone file, which is essentially a shortcut from one place to another operating system. In this case, this leads to a restricted communications channel, or "socket", between the various programs that alter evasi0n for your benefit.

"Evasi0n alters the socket that allows programs to communicate with a program called Launch Daemon, abbreviated launchd, the main process that loads when you start your iOS device and can run applications that require permits" root ", a step beyond the control of the operating system which grants users by default. This means that every time a backup of an iPhone or an iPad running ensures that all programs access the zone file and, thanks to "symlink", access to launchd. "

These are just some of the steps mentioned in the Forbes interview. If you want to read the full article and see what it's really hard to do the Jailbreak you have it available here . It's crazy to think that in the time it reaches us users only have to click a button.
