Russian-based InteVyDis group has released an untethered jailbreak for A4 devices on iOS 5.1.1 as part of Vulndisco Mobile 1.7. The module is vd_ios_untether_5_1_1. It is totally not from Pod2g's jailbreak source, and it even doesn’t come free. Jailbreakers should keep in mind that Pod2g's Absinthe 2.0 should be out there in no time.

vulndisco mobile 1.7 is out with untethered 5.1.1

It works by creating a custom bundle you have to install via RedSn0w.

The module builds a bundle you have to install on the device with the help of redsn0w tool. Finally the device will be jailbroken and you'll get remote CANVAS shell.

Legerov and Shuva10v are two hackers who are behind InteVyDis, a company which sells tools and aftermarket plugins for security professionals. InteVyDis has been in the game for a while, at least since 2008.

A lot of people are going to mistake InteVyDis untether solution for a consumer product. The first hint that this jailbreak is not intended for you (unless you’re a professional security researcher) is that the software InteVyDis’ plugin relies on is Immunity CANVAS, which costs $995 (plus $495 per 3 months for updates). That price is before the undisclosed amount which InteVyDis is charging for their VulnDisco Mobile plugin. As a modder and homebrew enthusiast, I’m not even going to bother asking how much a license from InteVyDis costs. You can email them if you want a quote.

The untether module is currently limited to A4 devices, with support for A5 devices planned for the future. According to their YouTube demo, the module builds a custom package which can be installed through RedSn0w.

This is their demo:

You might be wondering why anyone would be willing to spend over a grand to untether their iPhone 4, especially when Pod2g will be releasing his untethered exploit for every iOS device (minus the Apple TV 3) any day now. In all likelihood, the untether is just icing on the cake… and an inexpensive way of generating free advertising. In addition to untethering the device, VulnDisco Pack Professional seems to include iPhone support for Immunity CANVAS’ MOSDEF environment (which allows for the remote commands seen in the video) as well as other tools for testing mobile related security issues.

The new jailbreak tool was first discovered by iOS hacker i0n1c, and he keeps a positive opinion for the commercial jailbreak tool. So far, MuscleNerd and Pod2g has announced a objection concern. Now it's quite a argument in jailbreak community. We will bring you more informations.

Again, Pod2g's Absinthe 2.0 will be out in no time.
