 Plaso 20211024 released

The Plaso team is pleased to announce a new Plaso release, 20211024. This release has a mixture of new features and under the hood improvements.

Notable changes

  • Windows EventLog message (template) string extraction has been integrated (#636). Note that log2timeline.py and psteal.py will enable this feature by default but can be disabled with "--no_extract_winevt_resources".

  • The “file_hashes” analysis plugin has been replaced by a report that can be generated by “pinfo.py --report file_hashes case.plaso” (#3718)

  • The filestat parser has been changed to include additional information such as owner user identifier (UID) and group identifier (GID) (#3883) and names of extended attributes on ext, HFS+/HFSX and XFS (#3893).

  • Log2timeline.py and psteal.py now handle localized (#3751) and MUI form (#3754) Windows time zone names.

  • Thanks to @sydp a Fish shell history (#3802) and a Linux locate (updatedb) database (#3799) parsers were added, and the Firefox cache file parser now supports format version 3 (#3827).

  • The legacy positional argument to specify a Plaso storage file name (.plaso) for log2timeline.py has been removed (#3606).

  • The Plaso SQLite storage format has been changed to store 1 event tag per event (#3601). Due to historical reasons, dating back to the ZIP-based Plaso storage file format, event tags were previously appended.


The full list of cleanups, performance tweaks and bug fixes can be found in the release milestone. 

Upcoming changes in future releases

  • Additional improvements to Windows EventLog resource extraction (#163).

  • Support for reading and updating Plaso storage files that have multiple event tags per event will be removed in the 2022 February release (#3714).


Where/how to get Plaso 20211024?

See Plaso's Users' Guide. The development team recommends using Docker to install Plaso without hassle. 


If Docker does not fit your needs there are installation instructions available for MacOS, Ubuntu and Fedora. 


If you run into problems take a look at the Installation Problems page in the Plaso documentation, to see if other people have seen the issue before. If nothing there helps, ask for help on the Open Source DFIR slack or open an issue on the tracker.

Parsing the $MFT NTFS metadata file

By
Background Numerous articles have been written about parsing the $MFT NTFS metadata file before. Some of these explain the technique itself [ 1 ] and others mostly focus on how to use tools. Rarely do articles mention the pros and cons of the technique from a digital forensics perspective [ 2 ].  What is $MFT parsing?  For readers not familiar with the NTFS file system, MFT stands for Master File Table. This table is stored in a file system metadata file, meaning that as far as the file system is concerned it is a file, however that the file contains file system metadata not “regular” content. The name of this file is “$MFT”.  The MFT consists of a sequence of (predetermined) fixed-size entries (or MFT entries). These entries are typically 1024 bytes in size, however the size is defined in the NTFS volume header and in a “regular” MFT entry itself.  The first 4-bytes of a “regular” MFT-entry (or record) starts with the signature “FILE”. The MFT entry can also be filled wit

Incident Response in the Cloud

By
Many organizations have begun moving a majority of their services towards the cloud in recent years. As a result, attackers have shifted their focus towards the cloud. This has resulted in new techniques and methods specifically designed to compromise cloud infrastructure, like the recent SALTSTACK vulnerability that was widely exploited [ 1 ]. Therefore it is critical for these organizations to have an incident response team that understands the new risks attached to cloud and how cloud can make incident response easier or harder.  In this blog post we will walk you through each phase you may encounter in traditional incident response and highlight the differences when adopting cloud computing. It is aimed towards both those who are new to incident response and cloud computing. We’ve included insights that will benefit organizations taking that step towards cloud who want to ensure they are prepared to respond efficiently to cloud incidents.  Traditional Incident Response Before jump

Container Forensics with Docker Explorer

By Anonymous
  Introduction As previous blog posts on cloud forensics have noted, applications are increasingly being deployed using container orchestration frameworks such as Kubernetes, especially in cloud environments.  Similar to traditional deployments on physical servers or virtual machines (VMs), when a containerised application has a security issue it can lead to a compromise of the underlying compute architecture. In the case of container deployments this means a compromise of the container itself, the container host, or even a wider cluster compromise via abuse of orchestration tools. Often digital forensics is required to establish what went wrong and remediate any issues. This article will provide an introduction to container forensics with Docker Explorer by working through a scenario involving a compromised container running within a Kubernetes cluster. Although Kubernetes is briefly mentioned, this article will focus on analysis of an individual container rather than the wider clust
