Usage

usage: objid_indx_parser.py [-h] -s SOURCE [--no_recover] [-o OUTPUT_TEMPLATE]
                            [--debug {ERROR,WARN,INFO,DEBUG}]

Parse the $O Index. The file can be found at \$Extend\$ObjId:$O.
    version: 0.0.1


optional arguments:
  -h, --help            show this help message and exit
  -s SOURCE, --source SOURCE
                        The $O Index or a logical volume (logical volume:
                        \\.\C:).
  --no_recover          Do Not Recover Object Entries.
  -o OUTPUT_TEMPLATE, --output_template OUTPUT_TEMPLATE
                        Output template format.
  --debug {ERROR,WARN,INFO,DEBUG}
                        Debug level [default=ERROR]

Output Templates

The output template is just a string that is used with Python's format function.

Example:

JSON Record:

By default the output is in JSONL format. Here is a raw json record (that has been indented for easier viewing).

}

Output Template

Lets say we want output to just display the mft entry, object id's timestamp, and the raw object id. We could give an output template of the following: {mft_reference[entry]},{object_id[timestamp]},{object_id[hex]}

If we wanted to find the same record as the previous json output example we could then filter through a grep like utility:

python .\objid_indx_parser.py -s \\.\C: -o "Recovered: {recovered},{mft_reference[entry]},{object_id[timestamp]},{object_id[hex]}" | rg ddecf9b9565de711a97840e23013d7af

If you run the tool with no output template, you get back the raw json. You can use that json output to know which fields exist in the data.
