Plaso 20210606 released

 Plaso 20210606 released

The Plaso team is pleased to announce a new Plaso release, 20210606. This release has a mixture of new features and under the hood improvements.

Notable changes

  • The “amcache” parser has been changed to a Windows Registry parser plugin and is now named “winreg/amcache”. If you’ve been referring to this parser by name, you’ll need to use its new name. In addition changes have been made to better support newer AMCache.hve formats.

  • Initial support to directly read from Mac OS disk images (.dmg, .sparseimage, .sparsebundle) (#3540). More details about which formats are supported can be found here.

  • As mentioned in previous release notes, the default ext2, ext3 and ext4 dfVFS back-end is now libfsext/pyfsext (#495), the default HFS+ and HFSX back-end is now libfshfs/pyfshfs (#494) and the default GPT back-end is now libvsgpt/pyvsgpt.

  • Changes to extract additional values of Chrome file download database (with thanks to @obsidianforensics).

  • Improved the resilience of various parsers to data format edge cases and corrupted source data including: apache (with thanks to @debernal), asl, iis (with thanks to @colemanjp), mactime, mac_keychain, plist, spotlight_storedb, winevtx, winreg (with thanks to @MikeHofmann).

  • Additional tagging rules for Linux (with thanks to @pyllyukko) and Windows (with thanks to @lprat).

  • Log2timeline.py no longer requires the Plaso storage file (.plaso) as an explicit command line argument. Similar to psteal.py, log2timeline.py now will generate a Plaso storage file name based on the source and date and time (#510). A Plaso storage file name can still be set using a positional argument as before (legacy method) and with the "--storage-file" command line option.

  • A warning was added to psort.py to discourage the use of second-only granularity and restricted field output formats such as tln, l2ttln and l2tcsv (#3570). More information about the shortcomings of these formats can be found here and here.

  • Added the "--dynamic-time" option to psort.py to preserve date and time values in their original granularity (#3582).

  • Pinfo.py will now report fewer extraction warnings since warnings due to recovery are now reported separately (#1381).


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

Upcoming changes in future releases

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