BestCrypt, developed by the Finnish company Jetico, is a cross-platform commercial disk encryption tool directly competing with BitLocker, FileVault 2 and VeraCrypt. Volume encryption is available for Windows and macOS. Learn how to break BestCrypt full-disk encryption by recovering the original password!

Backups are the primary way to preserve data. On smartphones, backups are handled automatically by the OS. Windows lacks a convincing backup app; numerous third-party tools are available, some of which feature strong encryption. Computer backups may contain valuable evidence that can be useful during an investigation – if you can do something about the password.

When analyzing connected computers, one may be tempted to pull the plug and bring the PC to the lab for in-depth research. This strategy carries risks that may overweigh the benefits. In this article we’ll discuss what exactly you may be losing when pulling the plug.

Released back in 2013, VeraCrypt picks up where TrueCrypt left off. Supporting more encryption algorithms, more hash functions and a variable number of hash iterations, VeraCrypt is the default choice for the security conscious. VeraCrypt has no known weaknesses except one: once the encrypted disk is mounted, the symmetric, on-the-fly encryption key must be kept in the computer’s RAM in order to read and write encrypted data. A recent change in VeraCrypt made OTF key extraction harder, while the latest update to Elcomsoft Forensic Disk Decryptor attempts to counter the effect of the change. Who is going to win this round?

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.

As opposed to live system analysis, experts performing the cold analysis are not dealing with authenticated user sessions. Instead, cold analysis can be viewed as an intermediary measure with live system analysis on the one end and the examination of a forensic disk image on another. Why and when would you use cold system analysis, what can you do and what benefits does it bring compared to the traditional approach? Read along to find out.

Accessing a locked system is always a challenge. Encrypted disks and encrypted virtual machines, encrypted files and passwords are just a few things to mention. In this article we are proposing a straightforward workflow for investigating computers in the field.

Breaking LUKS Encryption

August 18th, 2020 by Oleg Afonin

LUKS encryption is widely used in various Linux distributions to protect disks and create encrypted containers. Being a platform-independent, open-source specification, LUKS can be viewed as an exemplary implementation of disk encryption. Offering the choice of multiple encryption algorithms, several modes of encryption and several hash functions to choose from, LUKS is one of the tougher disk encryption systems to break. Learn how to deal with LUKS encryption in Windows and how to break in with distributed password attacks.

The wide spread of full-disk encryption makes live system analysis during incident response a challenge, but also an opportunity. A timely detection of full-disk encryption or a mounted crypto container allows experts take extra steps to secure access to encrypted evidence before pulling the plug. What steps are required and how to tell if the system is using full-disk encryption? “We have a tool for that”.

There is a bit of confusion about our software designed to allow breaking into password-protected systems, files, documents, and encrypted containers. We have as many as three products (and five different tools) dealing with the matter: Elcomsoft Forensic Disk Decryptor (with an unnamed memory dumping tool), Elcomsoft System Recovery and Elcomsoft Distributed Password Recovery, which also includes Elcomsoft Hash Extractor as part of the package. Let’s briefly go through all of them. Hopefully it will help you select the right product for your needs and save time in your investigation.
