CLI wrapper for malware bazaar API (bazaar.abuse.ch) and YARAify API (yaraify.abuse.ch)
Project description
malwarebazaar
A MalwareBazaar and YARAify API wrapper and CLI
This python module provides a Python API for MalwareBazaar as well as YARAify which can be used very easy to access both APIs:
from malwarebazaar import Bazaar, Yaraify
b = 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
Usage: bazaar [OPTIONS] COMMAND [ARGS]...
Query MalwareBazaar from the command line!
╭─ Options ─────────────────────────────────────────────────────────────────────────────────────╮
│ --install-completion [bash|zsh|fish|powershell|pwsh] Install completion for the │

│ init Initialize bazaar config file. │
│ query Query the MalwareBazaar API. │
│ recent Get information about recently submitted samples. The API allows either the last 100 │
│ samples or samples uploaded in the last 60 minutes. As the amount is quite big, the │

│ version Print and check bazaar version. │
╰───────────────────────────────────────────────────────────────────────────────────────────────╯

Installation
Usually, 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 malwarebazaar
If you want to use the CLI, you need to include the cli extra:
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.
Usage
Python API
from malwarebazaar import Bazaar, Yaraify
from malwarebazaar.models import Sample, YaraRule
b = Bazaar(
api_key="myapikey"
)
y = Yaraify(
api_key="myapikey"
)
response = b.query_recent()
samples = [Sample(**sample_dict) for sample_dict in response["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) for yara_dict in response["data"]]
for yara in yaras:
if yara.rule_name != "classified":
rule = y.download_yara(yara.yarahub_uuid)
print(rule)
break
There is no dedicated API documentation, however, the function names are pretty self-explanatory and you can just take a look at the respective API functions here:
- Bazaar: bazaar.py
- YARAify: yaraify.py
CLI
This module provides two CLI commands: bazaar and yaraify.
They use the same configuration file and must be initialized with the specific API key before they can be used.
Optionally, auto-completion can be installed for your shell via bazaar --install-completion <shell> (same for
yaraify).
bazaar example
$ bazaar init myapikey
Successfully set API-Key!
