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.

Elcomsoft System Recovery 8.30 introduced the ability to break Windows Hello PIN codes on TPM-less computers. This, however, was just one of the many new features added to the updated release. Other features include the ability to detect Microsoft Azure accounts and LUKS2 encryption, as well  as new filters for bootable forensic tools.

Many Linux distributions including those used in off the shelf Network Attached Storage (NAS) devices have the ability to protect users’ data with one or more types of encryption. Full-disk and folder-based encryption options are commonly available, each with its own set of pros and contras. The new native ZFS encryption made available in OpenZFS 2.0 is designed to combine the benefits of full-disk and folder-based encryption without the associated drawbacks. In this article, we’ll compare the strengths and weaknesses of LUKS, eCryptFS and ZFS encryption.

Established NAS manufacturers often offer some kind of encryption to their users. While anyone can use “military-grade AES-256 encryption”, the implementation details vary greatly. Synology, Asustor, and TerraMaster implement folder-based encryption, while QNAP, Thecus, and Asustor (MyAcrhive) employ full-disk encryption; the full comparison is available here. In this article, we’ll have a look at encryption methods used in TrueNAS, a system commonly used by computer enthusiasts for building custom NAS servers.

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”.
