In older iPhones, the ‘file system dirty’ flag indicates unclean device shutdown, which affects the ability to perform bootloader-level extractions of Apple devices running legacy versions of iOS (prior to iOS 10.3 released in March 2017). As such, the “file system dirty” flag must be cleared before the extraction. In this article we discuss the very different forensic implications of this flag if it is set on the Data or System partitions.

Have an iPhone backup but cannot get around the password protection? I have a story to share. I was recently contacted by an old partner from the other side of the world who asked for assistance in an urgent case. He had an iTunes-style backup of a device full of critical evidence, but the password locked him out of the data.

There was a 3-fold increase in identity theft and more than 2-fold increase in phishing attacks registered in 2020 compared to 2019 according to IC3 report. A whopping 50 – 81% of attacks (depending on who you read) are targeting both corporate and private sectors to steal users’ login credentials; that is, passwords. No matter what changes happen in data security, passwords remain the most wide-spread means of protection.

iOS Forensic Toolkit 7.0 brings low-level extraction support for the latest generation of Apple devices. This includes the entire range of iPhone 12 models as well as all other devices capable of running iOS 14.0 to 14.3. Learn how to image the latest iPhone models without a jailbreak.

The iPhone recovery mode has limited use for mobile forensics. However, even the limited amount of information available through recovery mode can be essential for an investigation. Recovery access can be also the only available analysis method if the device becomes unusable, is locked or disabled after ten unsuccessful unlocking attempts, or had entered the USB restricted mode. Learn how to enter and leave Recovery and what information you can obtain in this mode.

True physical acquisition is back – but only for a handful of old devices. We’re adding support for unlocking and forensically sound extraction of some of Apple’s legacy iPhones. For iPhone 4, 5, and 5c devices, we’re adding software-based passcode unlocking and device imaging functionality. Moreover, on some models you won’t even need to break the passcode in order to make a full disk image! In this walkthrough we’ll describe the steps required to image an iPhone 4, iPhone 5 or iPhone 5c device.

DFU Mode Cheat Sheet

January 14th, 2021 by Oleg Afonin

The Device Firmware Upgrade mode, or simply DFU, just got a second breath. The ability to image the file system, decrypt the keychain and even do passcode unlocks on some older iPhone models has been made possible thanks to the checkm8 exploit and the checkra1n jailbreak, both of which require switching the phone into DFU. The procedure is undocumented, and the steps are different for the various devices.

Shame on us, we somehow missed the whole issue about Apple dropping plan for encrypting backups after FBI complained, even mentioned in The Cybersecurity Stories We Were Jealous of in 2020 (and many reprints). In the meantime, the article is full of rumors, guesses, and unverified and technically dubious information. “Fake news”, so to say. Is there truth to the rumors, and what does Apple do and does not do when it comes to encrypting your personal information?

Investigating a BitLocker-encrypted hard drive can be challenging, especially if the encryption keys are protected by the computer’s hardware protection, the TPM. In this article, we’ll talk about the protection that TPM chips provide to BitLocker volumes, and discuss vulnerabilities found in today’s TPM modules.

The iPhone backup is one of the hottest topics in iOS forensics. iTunes-style backups are the core of logical acquisition used by forensic specialists, containing overwhelming amounts of evidence that is is unrivaled on other platforms. The backups, as simple as they seem, have many “ifs” and “buts”, especially when it comes to password protection. We wrote a thousand and one articles about iOS backup passwords, but there is always something fresh that comes out. Today we have some new tips for you.
