⚙️ How It Works

🔍 Understanding the Checkm8 Exploit

Checkm8 is a BootROM exploit discovered in 2019 that affects all Apple devices running on A5 to A11 chipsets. Since BootROM is stored in read-only memory (ROM), Apple cannot patch this vulnerability through software updates, making Checkm8 a permanent and reliable exploit for iCloud bypassing.

🚀 Bypass Process Overview

Step 1: DFU Mode Exploitation

• The process begins by putting the device into Device Firmware Update (DFU) mode.

• Onii Ramdisk exploits a use-after-free vulnerability in the BootROM’s USB handling.

Step 2: Heap Manipulation

• This step controls memory allocation within the device’s BootROM, allowing execution of arbitrary code.

Step 3: Payload Injection

• Custom shellcode is injected into the device, disabling iCloud security checks and allowing the bypass process to proceed.

Step 4: Bypassing Hello Screen

• Once the exploit is executed, Onii Ramdisk skips the Apple authentication screen, allowing users to access the home screen without entering Apple ID credentials.
