Cant Decrypt Ios 9.3.5 Dmg

The update has been released for the iOS 9.3.5 and it will patch the various zero-day vulnerabilities that have been deployed supposedly by governments. Citizen Lab and Lookout Security informed the iPhone maker about the spyware and the company quickly released the patch, within ten days to be precise. Can't Decrypt Ios 9.3.5 Dmg 1 Apple today released an iOS 9.3.5 update for the iOS 9 operating system, almost a month after releasing iOS 9.3.4 and a few weeks before we expect to see the public release of iOS 10, currently in beta testing.

Firmware Keys are keys which decrypt bootloaders, ramdisks, and root filesystem of iOS firmware, if those components are encrypted. Apple uses encryption to make it harder to analyze and modify them. Over time Apple changed the way they encrypt firmware files, hence the way to decrypt them and get decryption keys changed as well.

History

With the release of the iPhone came the IMG2 file format. They were used on all known iPhone OS1.x firmwares. For the 1.1.x series, they were encrypted with the 0x837 key. The discovery of the 0x837 key led to the ability to decrypt any 1.x firmware.

Following IMG2 came the IMG3 file format. They were introduced with iPhone OS 2.0 beta 4, and have been in use ever since. In order to maintain their integrity, they use multiple layers of encryption. Apple took encryption seriously with IMG3 by utilizing AES (based on the Rinjndael key schedule). In terms of the pre-iPhone OS 3 VFDecrypt key, it is stored as plain-text in the '__restore' segment of the ASR image within the ramdisks.

The ramdisk keys can only be retrieved with the processor specific GID Key. The GID key is currently unretrievable and can only be utilized through the built-in AES engine. To complicate things even more, the engine is only accessible through a special bootrom or iBoot exploit (jailbreaks typically expose it with /dev/aes_0). This makes usage of the key nearly impossible.

A: Many problems and bootloops can be caused by buggy or incompatible tweaks. Remember many tweaks never saw iOS 13 in the pre-checkra1n era. If you suspect a recently installed tweak, you may attempt to enter no-substrate mode by holding vol-up during boot (starting with Apple logo until boot completes). If the issue goes away, a bad tweak is.

However, once you have access to the AES engine, the entire system falls apart. You are able to upload an encrypted ramdisk and grab the decryption keys for it. Once you manage to decrypt the ramdisk, you can run it through GenPass to decrypt the firmware key.

To find the keys, you can either use the methods on AES Keys or the easier option for OS X, keylimepie.

Notes

Certain files share the same key and IV per application processor (per build) provided the devices have the same pixel resolution:

The table on the right lists the application processors and their corresponding devices. This list is also accessible from the main page.

You can use img3decrypt or xpwntool to decrypt these files as described in Decrypting Firmwares. Once done, mount or extract using the tool of your choice.

The firmware version number for the Apple TV builds are the ones that the Apple TV reports (also known as the 'marketing version').

All dates are relative to UTC.

GID AES is used by iBoot to decrypt firmware images. When iBoot loads the kernelcache, GID AES is disabled. This means in order to get firmware keys, you must gain code execution in a setting where GID AES is still enabled. In most cases, this means exploiting iBoot itself, before the kernelcache is loaded.

Firmware Versions

This is a full and comprehensive list of all firmwares Apple Inc. has made available to the public in some way, be it the dev center or iTunes. This list also contains a few firmwares for which there never was an IPSW (as far as can be told) such as 4.2.5 for the CDMA iPhone 4 (iPhone3,3). These few builds came preinstalled on the device, but are not available for download.

In today's video I show you how to properly decrypt iOS 10's Ramdisk and extract ASR Application on OS X. You probably know that iOS 10's Ramdisk, even if not protected with AES and IV keys, was still impossible to open on OS X due to the an image related error. Now that xerub published IMG4Tool, you are able to decompress the file from it's containers and make it a true DMG file that can be browsed normally. After this, extraction of ASR is as easy as a few clicks.

If you want to disassemble ASR, you can use Hopper Disassembler V3. I've shown you in the video how to feed the app to the disassembler. At this point, patches for ASR can be created. Even tho patching ASR would require iBEC and iBSS patches as well, which in other hand require an iBOOT Exploit.

This video is created more for developers who know Assembly because disassembled ASR creates an ARM Assembly output in Hopper.

You can do this on Windows as well, just download the Windows version of the IMG4Tool available here in the description.

Thanks xerub for IMG4TOOL!

Also, the keys for iOS 9.3.5 iPhone 6,1 (5S) are now up on the iPhone Wiki, if anybody is still on that version.
