The seventh beta of iOS Forensic Toolkit 8.0 for Mac introduces passcode unlock and forensically sound checkm8 extraction of iPhone 4s, iPad 2 and 3. The new solution employs a Raspberry Pi Pico board to apply the exploit. Learn how to configure and use the Pico microcontroller for extracting an iPhone 4s!

Installing the checkm8 exploit to perform forensically sound extractions with iOS Forensic Toolkit can be tricky, which is in part due to certain hardware peculiarities.  If you watch our blog, you might have already read the article on checkm8, checkra1n and USB hubs. We have some good news: we managed to fix some of the issues with or without the use of a USB hub.

The second beta of iOS Forensic Toolkit 8.0 has arrived, offering repeatable, verifiable extraction for a limited range of iOS devices. The new release introduces a brand-new user interface, which differs significantly from the selection-driven console we’ve been using for the past several years. This article describes the new workflow for performing forensically sound extractions with iOS Forensic Toolkit 8.0 beta2.

If you ever used the checkra1n jailbreak or the checkm8 acquisition method available in some mobile forensic products like iOS Forensic Toolkit, you know that the trickiest parts of the process are the first two: entering DFU, and using the exploit itself. Even if you have the right cables and enough experience, sometimes you may still bump into a weird issue or two. The device may not enter DFU whatever you do, or the exploit fails. How can you increase your success rate?

Switching the iPhone into DFU mode is frequently required during the investigation, especially for older devices that are susceptible to checkm8 exploit. However, switching to DFU requires a sequence of key presses on the device with precise timings. If the device is damaged and one or more keys are not working correctly, entering DFU may be difficult or impossible. In this guide, we offer an alternative.
