Rekall 1.4.0 (Etzel) is released

This is the next release of the Rekall Memory Forensic framework, code named after the Etzel pass, not far from Zurich.
I am excited to announce the new Rekall release is out. This release introduces a lot of revolutionary features. Some of the more exciting new features include:
  • Windows support:
    • Windows 10 - This release supports WIndows 10 in most plugins. Although support is not complete yet, we will be working hard to make all plugins work in subsequent releases.
    • Better support of pagefiles. The address translation algorithm in Rekall has been overhauled and re-written. The new code supports describing the address translation process for increased provenance (using the vtop plugin). On Windows, Rekall now supports mapping files into the physical address space. This allows plugins to read memory mapped files transparently (if the file data is available).
    • Better heap enumeration algorithms. Rekall supports enumerating more of the Low Fragmentation Heap (LFH). Currently heap enumeration is only supported on 64 bit Windows processes compiled with MSVC.
    • All references to file names are now written with the full drive letter and path. Drive letters and path normalization is done by following the symlinks in the object tree. 
    • The new mimikatz plugin contributed by Francesco Picasso has been completely overhauled - it now also provides master keys from lsasrv as well as livessp analysis.
  • OSX and Linux support:
    • Common interactive plugins were added like address resolver/dump/cc/pas2vas etc. This improves the workflow with these OSs.
    • Sigscan is now available for all OSs: Quickly determine if a machine matches a hex signature that supports wildcards.
  • Framework
    • Rekall now has persistent stable cache. This means that re-launching Rekall on an image we analyzed in the past will suddenly be very fast. This is especially useful for plugins like pas2vas which take some time to run initially but when run subsequently this will be very fast.
    • Logging API changes. Logging is now done via the session object allowing external users of Rekall as a library to access log messages.
    • Efilter querying framework was externalized into its own project and expanded.
  • Packaging
    • Rekall is now separated into three packages:
    • Rekall core contains all you need to use Rekall as a library. It does not have ipython as a dependency but if you also install ipython, the core can use it.
    • Rekall GUI is the Rekall web console GUI.
    • Rekall is now a metapackage which depends on both other packages.
  • Imaging
    • Rekall gained the aff4acquire plugin in the last release but now:
    • The plugin can acquire pagefiles by itself using the Rekall NTFS parser.
    • Also acquire all the mapped files. This resolves all address translation requirements during the analysis stage as Rekall can later map all section objects to read memory mapped files.
As usual you can download the latest release from our download page
