Lockdown Mode is a sometimes overlooked feature of Apple devices that broadly make them harder to hack. A court record indicates the feature might be effective at stopping third parties unlocking someone's device. At least for now.

The FBI has been unable to access a Washington Post reporter’s seized iPhone because it was in Lockdown Mode, a sometimes overlooked feature that makes iPhones broadly more secure, according to recently filed court records.

The court record shows what devices and data the FBI was able to ultimately access, and which devices it could not, after raiding the home of the reporter, Hannah Natanson, in January as part of an investigation into leaks of classified information. It also provides rare insight into the apparent effectiveness of Lockdown Mode, or at least how effective it might be before the FBI may try other techniques to access the device.

“Because the iPhone was in Lockdown mode, CART could not extract that device,” the court record reads, referring to the FBI’s Computer Analysis Response Team, a unit focused on performing forensic analyses of seized devices. The document is written by the government, and is opposing the return of Natanson’s devices.

    I don’t think that’s a rational line of thinking, because there are documented filings of attempted file access into FOSS programs that the FBI are unable to influence and are completely unable to access, such as Veracrypt/LUKS encrypted PCs and GrapheneOS in BFU/Duress password entry status.

    Now, Apple is indeed a proprietary ecosystem, and as such unable to have community outside assurances that their system is completely trustworthy. However, Lockdown has now joined the ranks of other systems of data security that have been proven effective against a warrant, perpetuating the cycle in which nations such as the UK (and the US during the Crypto Wars) have tried to overtly undermine the technology through public actions after failures to covertly crack them. You cannot classify mathematics, physics, or cryptography, and there is no such thing as a perfect backdoor (despite some senators’ opinions).

    With all that being said, I still wouldn’t trust an iPhone, but I don’t think that proposed line of thinking meshes with the FBI.
