Forensic Analysis of Windows 10 and 11 Event Logs
February 18th, 2026 by Oleg Afonin
The discipline of digital forensics and incident response relies fundamentally on the persistent, systemic traces left by both legitimate users and malicious actors. The Windows Event Log system serves as a primary chronological record of operating system activity, capturing security events, application behaviors, service and driver activity, and user authentication telemetry. Due to the immense volume of background events generated by Windows 10 and Windows 11, isolating forensically relevant artifacts is a highly specialized task. A comprehensive understanding of this logging mechanism is often decisive when reconstructing an incident timeline.
Secure Instant Messengers
January 19th, 2021 by Olga Koksharova
In today’s world of everyone wanting a slice of one’s personal information, users become more and more concerned about the privacy. The WhatsApp/Facebook integration raised an additional concern, considering that Facebook-owned Messenger requests the largest number of invasive permissions among all commonly used messengers. Data privacy and security concerns are mounting like a snowball. 2020 brought multiple data breach incidents from popular blogging resources from LiveJournal whose users’ data was breached and leaked to the darknet to financial institutions like Postbank with 12M exposed credit cards, hospitality giants as Mariott with 383 million records compromised or even Microsoft customers who also suffered from privacy-related issues.
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
January 7th, 2021 by Vladimir Katalov
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?
Apple Scraps End-to-End Encryption of iCloud Backups
January 6th, 2021 by Oleg Afonin
Reportedly, Apple dropped plan for encrypting backups after FBI complained. Apple’s decision will undoubtedly cause turmoil and will have a number of consequences. In this article, I want to talk about the technical reasons for encrypting or not encrypting cloud backup, and compare Apple’s approach with the data encryption strategies used by Google, who have been encrypting Android backups for several years.
Understanding BitLocker TPM Protection
January 5th, 2021 by Andrey Malyshev
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.
2020 in Review: What Was New in Desktop and Mobile Forensics
December 28th, 2020 by Oleg Afonin
This year is different from many before. The Corona pandemic, the lack of travel and canceled events had changed the business landscape for many forensic companies. Yet, even this year, we made a number of achievements we’d love to share.
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. 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.
New Privacy Features: iOS 14.0 through 14.3
December 18th, 2020 by Oleg Afonin
Apple has long provided its users the tools to control how apps and Web sites use their personal data. The release of iOS 14 brought a number of new privacy features, while iOS 14.3 adds an important extra. At the same time, one of the most interesting privacy features is facing tough opposition from a group of digital advertising associations, making Apple postpone its implementation.
Breaking Passwords with NVIDIA RTX 3080 and 3090
December 17th, 2020 by Oleg Afonin
Today we have an important date. Advanced Office Password Recovery turned 16. What started as an instant recovery tool for legacy versions of Microsoft Word had now become a GPU-accelerated toolkit for breaking the many Microsoft formats. Today we’re releasing a major update, giving Advanced Office Password Recovery and Distributed Password Recovery tools the ability to crunch passwords faster with the newest and latest NVIDIA 3000-series graphic boards. 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.
