With the introduction of new mitigations in iOS 15 (and especially 15.2), creating a jailbreak became significantly more difficult. Before, a kernel vulnerability was enough for jailbreaking but now a PAC or PPL bypass is required as well. Some people even said that iOS 15.1.1 will be the last version to receive a public jailbreak ;) \n\n In my talk I will show how it is possible to jailbreak iOS 15.4.1 even with all the latest mitigations. I'll describe the vulnerabilities exploited in the Fugu15 chain and how some of the mitigations introduced in iOS 15.2 can be bypassed. A demo of Fugu15 will also be shown, including an interesting (and uncommon) way to install Fugu15 on a device.
