They are to be run through two layers of scripts: a lower-layer set of scripts located in the bin/ subfolder and a higher-layer set of scripts in the scripts/ subfolder. government.External tools are located in the tools/ subfolder. We feel we must speak up in the face of what we see as an overreach by the U.S. Opposing this order is not something we take lightly.

The government could extend this breach of privacy and demand that Apple build surveillance software to intercept your messages, access your health records or financial data, track your location, or even access your phone’s microphone or camera without your knowledge.

If the government can use the All Writs Act to make it easier to unlock your iPhone, it would have the power to reach into anyone’s device to capture their data. The implications of the government’s demands are chilling. This would make it easier to unlock an iPhone by “brute force,” trying thousands or millions of combinations with the speed of a modern computer. The government would have us remove security features and add new capabilities to the operating system, allowing a passcode to be input electronically. In the wrong hands, this software - which does not exist today - would have the potential to unlock any iPhone in someone’s physical possession.

The FBI wants us to make a new version of the iPhone operating system, circumventing several important security features, and install it on an iPhone recovered during the investigation. Tim Cook responded on the company's webpage, outlining a need for encryption, and arguing that if they produce a backdoor for one device, it would inevitably be used to compromise the privacy of other iPhone users: The order used the All Writs Act, originally created by the Judiciary Act of 1789, to demand the firmware, in the same way as other smartphone manufacturers have been ordered to comply. government ordered Apple to produce an IPSW file that would allow investigators to brute force the passcode of the iPhone. The FBI recovered iCloud backups from one and a half months before the shooting, and wanted to access encrypted files on the device. Government data accessĪfter the 2015 San Bernardino attack, the FBI recovered the shooter's iPhone 5C, which belonged to the San Bernardino County Department of Public Health. Since then, many tools were created for the decryption and modification of the root file system. While Apple does not release these keys, they can be extracted using different iBoot or bootloader exploits, such as limera1n (created by George Hotz, more commonly known as geohot).

Untill iOS 10, all the firmware files (including the root file system and Restore and Update ramdisks) were encrypted.

#ROOT FILE SYSTEM ENCRYPTION IPSW DMG ARCHIVE#

The archive is not password-protected, but iBoot, LLB, iBEC, iBSS, iBootData and the Secure Enclave Processor firmware images inside it are encrypted with AES. See also: SHSH blob § Exploits and countermeasures

Without SHSH blobs, the firmware will refuse to restore, thus making downgrades impossible in official fashion, due to Apple's limitation. īist is sent to Apple TSS server and checked in order to obtain SHSH blob at every restore. There are two more files named ' Build Manifest' and ' Restore Manifest', both in Apple Property List (.plist) format that checks the compatibility, holds the hashes in base64 format and instructs the device where to find the specific Firmware parts during the restore.

bbfw format (renamed zip file), and other firmware files. The file also holds the Kernelcaches, and a 'Firmware' folder which contains iBoot, LLB (Low-Level Bootloader), iBSS (iBoot Single Stage), iBEC (iBoot Epoch Change), the Secure Enclave Processor firmware, the Device Tree, Firmware Images (Apple logo, battery images, Recovery mode screen and more), baseband firmware files in. tvOS, audioOS and macOS also include a disk image for the recovery environment (recoveryOS). ipsw file itself is a compressed archive file (renamed Zip archive) containing at least three Apple Disk Image files with one containing the root file system of the OS and two ram disks for restore and update.
