dfIndexeddb

dfindexeddb is an experimental Python tool for performing digital forensic analysis of IndexedDB and leveldb files.

It parses leveldb, IndexedDB and javascript structures from these files without requiring native libraries.

The content of IndexedDB files is dependent on what a web application stores locally/offline using the web browser's IndexedDB API. Examples of content might include:

• text from a text/source-code editor application,
• emails and contact information from an e-mail application,
• images and metadata from a photo gallery application

Installation

$ pip install dfindexeddb

Installation from source

Linux

1. Install the snappy compression development package

    $ sudo apt install libsnappy-dev

2. Clone or download the repository to your local machine.

3. Create a virutal environemnt and install the package

    $ python3 -m venv .venv
    $ source .venv/bin/activate
    $ pip install .

Usage

A CLI tool is available after installation:

$ dfindexeddb -h
usage: dfindexeddb [-h] -s SOURCE [--json] {log,ldb,indexeddb} ...

A cli tool for the dfindexeddb package

positional arguments:
  {log,ldb,indexeddb}

options:
  -s SOURCE, --source SOURCE
                        The source leveldb file
  --json                Output as JSON

To parse a LevelDB .log file:

$ dfindexeddb -s <SOURCE> log -h
usage: dfindexeddb log [-h] {blocks,physical_records,write_batches,parsed_internal_key,records}

positional arguments:
  {blocks,physical_records,write_batches,parsed_internal_key,records}

options:
  -h, --help            show this help message and exit

To parse a LevelDB .ldb file:

$ dfindexeddb -s <SOURCE> ldb -h
usage: dfindexeddb ldb [-h] {blocks,records}

positional arguments:
  {blocks,records}

options:
  -h, --help        show this help message and exit

To parse a LevelDB .ldb or .log file as IndexedDB:

$ dfindexeddb -s <SOURCE> indexeddb -h
usage: dfindexeddb indexeddb [-h]

options:
  -h, --help  show this help message and exit
