Automatic Ssh CydiaIn the previous article, we looked at how we can use Keychain-Dumper and Snoop-it to analyze and dump the contents of the Keychain from an IOS device. In this article, we will look at how we can boot a non-jailbroken device using a custom ramdisk and analyze the contents of the device. So what is the need of booting a device using a custom ramdisk? Imagine a scenario where you only have temporary access to a device and you can’t jailbreak it. You just have access to the device for say like 30 minutes. In that time, you can boot the device using a custom ramdisk, brute force the passcode, and dump all the information for later analysis. The best thing is that the device does not need to be jailbroken in order for you to carry out this attack. Ofcouse, if the device is using a alphanumeric passcode, then it might take even more time to bruteforce the passcode. You can imagine this as similar to booting a windows machine with a Linux live CD, and then mounting the windows partition and then using the Linux OS to access the contents of the hard drive. However, booting a device using a custom ramdisk requires a bootrom exploit. The bootrom is the first significant code that runs on an iDevice. For this example, go to the VM instances page and click the SSH button next the instance where you want to add a RAM disk. Create a mount point for your RAM disk. $ sudo mkdir /mnt/ram-disk. Create and mount a new tmpfs RAM disk. You must determine a value for the size property that meets your storage requirements. IOS Application Security Part 13 – Booting a custom Ramdisk using.

Automatic Ssh RamdiskA bootrom exploit allows us to bypass the bootrom signature checks on the Low level bootloader and hence boot the device using a custom ramdisk. Such an exploit could also allow the user to run unsigned code and hence create an untethered jailbreak. A full list of all the publicly available bootrom exploits can be found. A bootrom exploit once found cannot be fixed by Apple by releasing a new IOS version but can only be fixed by a new hardware release. At the time of writing of this article, there is no bootrom exploit discovered from A5 device or later. The bootrom exploit we will be using in this article will only work on A4 devices. I will be using an iPod touch 4th Generation in this article as it has an A4 chip.
