Windows File System Artefacts Under C:\ProgramData
March 5th, 2026 by Oleg Afonin
This guide continues our ongoing series exploring Windows digital artefacts and their practical value during an investigation. Here, we turn our attention to the specific set of files located under the root path %ProgramData% (commonly C:\ProgramData\) and its subfolders. Unlike standard user profile folders, this directory typically houses system-wide data, shared application configurations, and background service caches that apply to the system as a whole. For investigators, this path offers a system-level perspective. Analyzing it can uncover historical activity, revealing events from background file transfers and software installations to Wi-Fi connections and security tool detections.
iOS Backups: Leftover Passwords
November 10th, 2022 by Oleg Afonin
In Apple ecosystem, logical acquisition is the most convenient and the most compatible extraction method, with local backups being a major contributor. Password-protected backups contain significantly more information than unencrypted backups, which is why many forensic tools including iOS Forensic Toolkit automatically apply a temporary backup password before creating a backup. If a temporary password is not removed after the extraction, subsequent extraction attempts, especially made with a different tool, will produce encrypted backups protected with an effectively unknown password. In this article we’ll talk about why this happens and how to deal with it.

iOS 16: Extracting the File System and Keychain from A11 Devices
September 22nd, 2022 by Vladimir Katalov
Bootloader-based acquisition is the only 100% forensically sound data extraction method for Apple devices. It is the only way to acquire the full set of data from those devices that run iOS 16, albeit with a huge caveat that makes the whole thing more of a brain exercise than a practical forensic tool. Let’s review the iOS 16 compatibility in iOS Forensic Toolkit and go through the whole process step by step.
Entering DFU: iPhone 8, 8 Plus, and iPhone X
September 13th, 2022 by Oleg Afonin
DFU (Device Firmware Update) is a special service mode available in many Apple devices for recovering corrupted devices by uploading a clean copy of the firmware. Forensic specialists use DFU during checkm8 extractions (Elcomsoft iOS Forensic Toolkit). Unlike Recovery, which serves a similar purpose, DFU operates on a lower level and is undocumented. Surprisingly, there might be more than one DFU mode, one being more reliable than the others when it comes to forensic extractions. The method described in this article works for the iPhone 8, 8 Plus and iPhone X.

Probing Linux Disk Encryption: LUKS2, Argon 2 and GPU Acceleration
August 16th, 2022 by Oleg Afonin
Disk encryption is widely used desktop and laptop computers. Many non-ZFS Linux distributions rely on LUKS for data protection. LUKS is a classic implementation of disk encryption offering the choice of encryption algorithms, encryption modes and hash functions. LUKS2 further improves the already tough disk encryption. Learn how to deal with LUKS2 encryption in Windows and how to break in with distributed password attacks.
