Seriously, this myth won't die. Repeat after me: the Secure Enclave in newer iPhones does *not* help against the FBI attack scenario.

@marcan42 which FBI attack scenario
@SwiftOnSecurity All of them except jailbreak. The "get Apple to help" scenario, the "NAND replay" scenario, the "FIB the CPU" scenario, etc

@marcan42 agree on first and last one. Isn't RPMB supposed to prevent second? TrustZone usually works with RPMB. -
@yifanlu No RPMB on any iPhone (it doesn't use eMMC). But also most eMMC has backdoors that make RPMB worthless anyway. - Show replies

@marcan42@SwiftOnSecurity Yeah, also confused there; isn't SE supposed to solve NAND replay attacks in particular? -
@11rcombs@SwiftOnSecurity It only solves software-based NAND replay attacks because it has an anti-replay EEPROM, which you can replay. - Show replies
