I was kidding ... It wasn’t meant to be an attack :-).

Thanks for posting that. I wasn’t working on anything that had to be secure when I was playing around with the FIB (I was probing an embedded EEPROM ironically) .... I am familiar with techniques to cover such embedded devices with metal layers as well as introduce traps so that if someone wanted to dig down through the metal with a FIB, they risk cutting power rails and the like. Similar techniques are implemented at the PCB level to prevent sniffing of DRAM busses hidden on inner layers of the PCB (I suspect Apple and other vendors have embedded encryption in front of the DRAM’s physical layer since they develop their own ASICs).

Anyway, I simply got sick of seeing people imply that the iPhone was hacked due to a security issue ... I highly doubted that was the case. Plus there were many people calling you out as if you were wrong about Apple’s security.

Thanks. I knew you knew your stuff. . . I posted the details for the benefit of everyone on here. The Secure Enclave is much more hardened than the Encryption Engine and I sincerely doubt that it will be as easy to get at without destroying/damaging what they are after.

It is difficult being attacked by the know-nothings who are convinced that Apple is doing this purely for PR purposes. . . these short-sighted people cannot see the very serious philosophical underpinnings of what Apple is doing or the long-term consequences of what a loss means for them personally.
