Rapid7 is pleased to announce the release of Velociraptor version 0.6.4 – an advanced, open-source digital forensics and incident response (DFIR) tool that enhances visibility into your organization’s endpoints. This release has been in development and testing for several months now and has a lot of new features and improvements.
The main focus of this release is in improving path handling in VQL to allow for more efficient path manipulation. This leads to the ability to analyze dead disk images, which depends on accurate path handling.
A path is a simple concept – it’s a string similar to /bin/ls that can be used to pass to an OS API and have it operate on the file in the filesystem (e.g. read/write it).
However, it turns out that paths are much more complex than they first seem. For one thing, paths have an OS-dependent separator (usually / or ). Some filesystems support path separators inside a filename too! To read about the details, check out Paths and Filesystem Accessors, but one of the most interesting things with the new handling is that stacking filesystem accessors is now possible. For example, it’s possible to open a docx file inside a zip file inside an ntfs drive inside a partition.
Dead disk analysis
Velociraptor offers top-notch forensic analysis capability, but it’s been primarily used as a live response agent. Many users have asked if Velociraptor can be used on dead disk images. Although dead disk images are rarely used in practice, sometimes we do encounter these in the ..
