The recent update to Elcomsoft Advanced Archive Password Recovery, our go-to tool for breaking passwords to encrypted archives, brought compatibility with RAR5 and 7Zip formats, and enabled multithreaded dictionary attacks. Which archive formats are the most secure, and which ones are the toughest to break? Read along to find out!

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.

Breaking Jetico BestCrypt

February 3rd, 2021 by Oleg Afonin

BestCrypt, developed by the Finnish company Jetico, is a cross-platform commercial disk encryption tool. Available for Windows, Linux, macOS and Android platforms, BestCrypt is delivered in two editions, one offering full-disk encryption and the other encrypting virtual disk volumes stored in containers, the latter being supported with our tools.

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.

More than a year ago, we started researching the available encryption options in off the shelf network attached storage devices. We started with Synology devices, followed by Asustor, TerraMaster, Thecus, and finally Qnap. The manufacturers exhibit vastly different approaches to data protection, with different limitations, security implications and vulnerabilities. Today we are publishing the aggregate results of our analysis.

The proliferation of always connected, increasingly smart devices had led to a dramatic increase in the amount of highly sensitive information stored in manufacturers’ cloud accounts. Apple, Google, and Microsoft are the three major cloud providers who also develop their own hardware and OS ecosystems. In this report, we’ll see how these companies protect their users’ highly sensitive information compared to each other.

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.

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.

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.
