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.
Apple, FBI and iPhone Backup Encryption: Everything You Wanted to Know

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?

NAS Forensics: QNAP Encryption Analysis
December 23rd, 2020 by Oleg Afonin
A year ago, we analyzed the encryption used in Synology NAS devices. We were somewhat disappointed by the company’s choice to rely on a single encryption layer with multiple functional restrictions and security reservations. Today we are publishing the results of our analysis of data encryption used in QNAP devices. Spoiler: it’s very, very different.
iPhone Backups: Top 5 Default Passwords
December 22nd, 2020 by Vladimir Katalov
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.

Powered by Ampere, the new generation of GPUs delivers unprecedented performance in modern video games. How do the new cards fare when it comes to accelerating the password recovery, and is an upgrade worth it for the forensic experts? Let’s find out.
Recovering Screen Time Passwords
December 15th, 2020 by Vladimir Katalov
The Screen Time password has been long recommended as an extra security layer. By setting a Screen Time password without any additional restrictions, Apple users could easily dodge attempts of changing or removing the screen lock passcode, resetting the iTunes backup password, or removing the activation lock. For a long time, removing the Screen Time password was not possible without either providing the original password or erasing the device. However, Apple had changed the way it works, making it possible to reset the Screen Time password with an iCloud/Apple ID password.
