“We couldn’t release Chimera. It’s too dangerous. The A5’s debug seamount allows not just bootrom hijacking but permanent firmware rootkitting. Once deployed, this exploit cannot be removed. It survives full restores. It survives NAND replacement. It is the ghost in the machine. I’m hiding this payload on the last known prototype A5 wafer. If you’re reading this, you found it. Congratulations. You now own a phone that no one—not even Apple—can ever fully scan or trust again. Use it wisely. Or don’t. Either way, you’re alone now.” He plugged the Arduino into his laptop
