Jailbreaking iOS 13 with unc0ver
This guide will take us through using Cydia Impactor to jailbreak iOS 13.5.0 (and lower) devices. This process is highly helpful for performing iOS pentesting, but will be useful for anyone who just wants to sideload apps or tweaks.
Note: iPhone 5 (A7) devices on iOS 12 are not supported by this unc0ver jailbreak at the moment. For this please see our guide to using checkra1n jailbreak.
At a high level we will do the following:
- Create an app specific password (Impactor needs to authenticate with Apple)
- Download Cydia Impactor
- Download the unc0ver IPA file.
- Use Impactor to sideload the IPA to the device
- Run the unc0ver app to perform the jailbreak.
1. Create an app-specific password
Head over to https://appleid.apple.com/account/home
Click ‘Generate Password..’ to enter a label and create the password. You should now have a password, keep this in a password safe:
2. Download Cydia Impactor
First head on over to the Cydia Impactor site and download the latest tarball:
Extract the archive:
$ tar zxvf Impactor64_0.9.52.tgz
This will extract Impactor to the current directory. Now run Impactor:
$ sudo ./Impactor
If your phone is detected, you should see the device ID appear in the first field:
If you don’t see the device ID, ensure the device is plugged in and ‘trusted’.
3. Download unc0ver IPA
Now head on over to the unc0ver jailbreak site at https://unc0ver.dev/
4. Run Impactor
Download the ipa file and drag and drop that over the Impactor GUI.
You should see a prompt appear for you Apple login ID and password:
If you’re curious if this is safe, you can confirm with Wireshark that Impactor only communicates with idmsa.apple.com:
Note for ubuntu users: If the drag and drop doesn’t work, pay close attention to where on the screen you are dropping. There is a very limited space where you can actually drop the IPA into the window – you should see a
+ character appear on the hand icon when you are mousing over a valid spot.
The yellow area shows where you can drop the IPA:
5. Running the unc0ver app
You should now see the unc0ver app on SpringBoard:
Open the unc0ver app and hit Jailbreak:
If successful you should see Cydia installed on SpringBoard, if not, just repeat the process until successful:
The device should now be jailbroken. This is one of the most important steps to start pentesting iOS applications.
