Discovered by security researcher axi0mX, Checkm8 is a affecting hundreds of millions of devices using the A5 through A11 chips (iPhone 4s to iPhone X, iPad 5th gen to iPad 7th gen, iPod touch 7th gen). Pwndfu Mac
Most users never interact with Pwndfu directly. Instead, they use , a user-friendly GUI tool. Pwndfu is a "tethered" exploit
Pwndfu is a "tethered" exploit. If the device reboots, the exploit is lost, and it must be re-connected to a Mac to be "pwned" again [1, 3]. It exploits the device to enter Pwned DFU
: The primary open-source tool for many iOS devices. It exploits the device to enter Pwned DFU mode, particularly for checkm8-compatible devices.
The Pwndfu Mac exploit targets a vulnerability in the XNU kernel's mach_port_t object, which is used for Inter-Process Communication (IPC) between macOS components. By leveraging this vulnerability, an attacker could potentially gain elevated privileges, allowing for arbitrary code execution, privilege escalation, and even sandbox escapes.
