Checkra1n jailbreak allows hackers to change or extract data from your device in a few different ways. First, they can bypass icloud, jailbreak and sniffing files on your device. Essentially, the jailbreak allows the hacker to dump the decrypted code from memory, which could expose sensitive IP and data. Second, the behavior of an app running on a jailbroken device can be modified or tweaked.
Based on the permanent, unpatchable BootROM exploit Checkm8, checkra1n tool works on A5 through A11 iOS devices, unless the device is rebooted. The jailbreak can also gain permanence by exploiting flaws in these chips’ BootROM or read-only memory used at the device’s startup, making it unpatchable via security update.
