Version 1.3.1 Dammastock.This release was made at the Rekall Memory Forensic Workshop at DFRWS. For the first time, we ran this workshop completely from the interactive Rekall web console. It was an astounding success, and an impressive medium to deliver an interactive workshop (Check it out here ).
- Memory Acquisition
- The major thrust for this release was the updating of the Pmem Acquisition tools to AFF4. In addition to the stable WinPmem 1.6.2, we have made available an experimental pre-release of the WinPmem 2.0 series.
- A consistent interface. The same command line arguments used for all operating systems.
- The new memory image format we have standardized on is AFF4. This allows us to store multiple streams in the image, such as the page file and additional files.
- The pmem imagers are able to embed different files inside the final AFF4 image, such as the kernel image and miscellaneous binaries.
- GUI Web Console
- The GUI was expanded to accommodate multiple sessions. A Rekall session is an object encapsulating all we know about a specific image. With multiple session support in the GUI, we are able to write a single web console document which runs plugins on multiple images simultaneously.
- The GUI was also adapted to allow for the export of static versions of the document, which can be hosted on a simple web server.
- Rekall will now automatically fetch missing profiles from the Microsoft Symbol Server for critical modules.
This was a huge pain point in the past - when MS updated kernels through a
patch the kernel was rebuilt resulting in a new profile. By the time the
Rekall team pushed the new profile to the profile repository, Rekall was
non-functional, requiring users to know how to generate new profiles manually.
This new release adds a setting (you can set it in the configuration file
permanently or just use the flag
--autodetect_build_local). The following values are allowed:
nonemeans that Rekall will not fetch profiles from the symbol server (but will still use the profile repositories specified in
basicis the default setting. Rekall will fetch profiles for selected modules, such as the kernel, win32k.sys, ntdll, tcpip etc. This is usually good enough for most plugins to function correctly.
fullin this setting Rekall will try the symbol server for all profiles it does not know about. This can be very slow but will produce the best outcome (e.g. disassembly output will be fully annotated).
- Added support for XEN paravirtualized guests.
