Secure EnclaveĪll current Apple devices are equipped with a security co-processor named Secure Enclave Processor (SEP). The enumeration of all 6-digit PINs, however, will take up to 21 hours. On these devices we can reach the speed of 13.6 passcodes per second, which only requires 12 minutes to try all possible combinations of 4-digit PINs.

On devices without Secure Enclave full passcode unlock is available with no escalating time delays: iPhone 5 and 5c Passcode Unlock with iOS Forensic Toolkit. This also means that one can reasonably try the short list of weak passcodes followed by a short list of PINs resulting from the social engineering attempt.

With escalating delays, it will take some 416 days to try all possible combinations of 4-digit passcodes, and 114 years to try all possible 6-gidit passcodes. If the device is restarted during a timed delay, the delay is still enforced, with the timer starting over for the current period. On devices with Secure Enclave, the delays are enforced by the Secure Enclave. PIN throttlingĪpple has a comprehensive article on Passcodes and passwords in which the company explains how escalating time delays discourage brute-force attacks.

Note that the Erase Data option can be set to a lower threshold through MDM or Microsoft Exchange ActiveSync, which could make it even more challenging to attack a PIN code without losing access to the data. This means you must have a solid understanding of the potential consequences of exceeding the limit, and must exercise reasonable caution when attempting to recover the passcode.

Therefore, if you are considering attempting to recover a PIN code, be careful not to exceed the allowable number of incorrect attempts. The risk of recovering PIN codes with the Erase Data option turned on is high, and experts must carefully balance the need for access to evidence with the potential risk of permanently deleting important information. This setting is also available as an administrative policy through a mobile device management (MDM) solution that supports this feature and through Microsoft Exchange ActiveSync, and can be set to a lower threshold.” Consecutive attempts of the same incorrect passcode don’t count toward the limit. According to Apple, “If the Erase Data option is turned on (in Settings > Touch ID & Passcode), after 10 consecutive incorrect attempts to enter the passcode, all content and settings are removed from storage. However, with the Erase Data option turned on, there is a risk that all content and settings on the device will be permanently deleted after 10 (or less) consecutive incorrect attempts to enter the passcode. In the context of forensic investigations, the ability to recover PIN codes can be critical to gaining access to evidence stored on a device. * While you can unlock the device with biometrics and connect a USB accessory, pairing the device to a computer would still require a PIN. The following table summarizes the differences between unlocking the device with biometrics (Touch ID/Face ID) and PIN code.Ĭheckm8 extraction (on compatible devices) The PIN is required even for extracting devices that are vulnerable to checkm8 as without the PIN most user data on the device will remain encrypted. A PIN code is needed to pair the device to the computer, which is a required pre-requisite to both the advanced logical and low-level extraction methods.

Without a PIN code, most acquisition methods (except manual analysis) may not be available. While some activities can be performed with a biometrically unlocked device (Face ID or Touch ID), a lot of activities require the use of a PIN code. In this article we’ll discuss the security of PIN codes.

While a passcode can be composed of an arbitrary number of alphanumeric characters, PINs are digit-only, fixed length passcodes. Simply put, a PIN code or passcode is the key to the content of an iOS device. The role of PIN codes/passcodes in mobile forensics How do these measures affect security, how much more security do six-digit PINs deliver compared to four-digit PINs, and do blacklists actually work? Let’s try to find out. In recent years, Apple had switched from 4-digit PINs to 6 digits, while implementing blacklists of insecure PIN codes.
