Researchers drop checkm8-style BootROM exploit for A12 and A13 iPhones
Summary
Researchers have discovered a new BootROM exploit for iPhones with A12 and A13 chips, similar to the checkm8 exploit. This vulnerability allows for permanent jailbreaks as it resides in the device's unpatchable SecureROM.
IFF Assessment
This vulnerability allows for unpatchable jailbreaks, which can be used by threat actors to bypass security measures on affected iPhones.
Severity
This vulnerability is critical due to its potential for remote code execution and its persistence in the unpatchable BootROM, allowing for deep system compromise and bypass of security controls.
Defender Context
This discovery represents a significant threat to the security of iPhones with A12 and A13 chips, as the BootROM exploit is unpatchable and could lead to persistent jailbreaks. Defenders should be aware of potential bypass techniques that leverage such deep-level vulnerabilities and monitor for any associated exploit development or misuse.
