Package: malwarebazaar
malwarebazaarAMalwareBazaarandYARAifyAPI wrapper and CLIThis python module provides a Python API for MalwareBazaar as well as YARAify which can be used very easy to
access both APIs:frommalwarebazaarimportBazaar,Yaraifyb=Bazaar(api_key="my_api_key")b.query_hash(...)y=Yaraify(api_key="my_api_key",malpedia_key="optional_malpedia_api_key")y.query_hash(...)Optionally, this module provides a CLI for both services, too:$ bazaar --help

╰───────────────────────────────────────────────────────────────────────────────────────────────╯InstallationUsually, this module will be distributed via PyPI. If you want to use pre-release versions, check the release section of
this repository. If you don't intent to use the CLI, you do not need to install the "cli eye candy modules" and stick to
the pure Python API via:pip install malwarebazaarIf you want to use the CLI, you need to include thecliextra:pip install malwarebazaar[cli]Note: Previous versions also included pre-built binaries, however, I stopped adding them.
Please just use a local python environment instead.UsagePython APIfrommalwarebazaarimportBazaar,Yaraifyfrommalwarebazaar.modelsimportSample,YaraRuleb=Bazaar(api_key="myapikey")y=Yaraify(api_key="myapikey")response=b.query_recent()samples=[Sample(**sample_dict)forsample_dictinresponse["data"]]file_content=b.download_file(samples[0].sha256_hash)# or response["data"][0]["sha256_hash"]response=y.query_recent_yara()yaras=[YaraRule(**yara_dict)foryara_dictinresponse["data"]]foryarainyaras:ifyara.rule_name!="classified":rule=y.download_yara(yara.yarahub_uuid)print(rule)breakThere is no dedicated API documentation, however, the function names are pretty self-explanatory and you can just take

They use the same configuration file and must be initialized with the specific API key before they can be used.
