IOS killer: jailbreak using checkra1n in questions and answers
Italian explorer Luca Todesco, known for looking for vulnerabilities in iOS over the past few years, released checkra1n, a new exploit-based jailbreak utility that exploits vulnerabilities in the bootloader of devices on A5-A11 processors. The danger is that he is using a “security hole” that Apple cannot fix with a software update.
Read more about the danger of checkra1n and how attackers can use it, said Sergey Nikitin, Deputy Head of the Laboratory of Computer Forensics Group-IB. Bonus – iPhone 7 jailbreak video.
Jailbreak checkra1n came out, what does it mean?
This means that users of all iOS devices with older processors can now feel significantly less secure. In concrete terms, all Apple mobile devices below the iPhone 10 inclusive are vulnerable.
Which version of iOS is vulnerable?
The fact is that the vulnerability found is hardware and does not depend on the version of iOS. Vulnerable code is located in that part of the hardware of the device, which is recorded once during production. Therefore, to close this vulnerability is programmatically impossible.
What is the danger?
Knowing the password code and having physical access to the device, you can completely extract data from it by copying the entire file system. Usually, without jailbreak, it is possible to copy only a small part of the data using iTunes Backup.
