MalwareBazaarHunter

MalwareBazaarHunter is a Python-based security tool designed to fetch the latest malware samples from the MalwareBazaar API and then use the VirusTotal API to filter out samples based on their detection ratio. This helps security researchers quickly pinpoint potentially overlooked threats for further analysis.

Features

• Sample Querying: Query the latest malware samples from the MalwareBazaar API using specified tags, numbers, and file types.
• Detection Ratio Filtering: Retrieve detection statistics from the VirusTotal API and filter samples based on a user-defined threshold.
• Sample Downloading: Automatically download filtered malware samples with support for streaming large files.
• Efficient HTTP Requests: Utilizes requests.Session to reuse connections and improve performance.
• Robust Logging: Implements detailed logging using Python's built-in logging module for easier debugging and error tracking.

Installation

1. Clone the Repository

   git clone https://github.com/yourusername/MalwareBazaarHunter.git
   cd MalwareBazaarHunter

2. Set Up a Virtual Environment and Install Dependencies

   It is recommended to use a virtual environment:

   python3 -m venv venv
   # On Linux/MacOS:
   source venv/bin/activate
   # On Windows:
   venv\Scripts\activate

   Install the required package:

   pip install requests

Configuration

Before running the tool, update the following parameters in the main() function of the script:

• VT_API_KEY: Your VirusTotal API key.
• TAG: The malware tag to query (e.g., "rat").
• TYPES: The malware file type to fittering (e.g, '["exe", "js", "ps1", "msi", "bat", "lnk", "vbs"]').
• AMOUNT: The numbers of malware files retrieved from MalwareBazaar (default is 50).
• MAX_DETECTION_RATIO: The maximum detection ratio threshold (e.g., 0.2 for 20%).
• DOWNLOAD_DIR: The directory where downloaded samples will be stored (default is samples).

Make sure to replace the placeholder API key with your actual VirusTotal API key.

Usage

Run the main script directly:

python main.py

The tool will perform the following steps:

1. Query the MalwareBazaar API for the latest malware samples based on the specified tag.
2. Retrieve each sample's detection ratio from the VirusTotal API.
3. Filter out samples whose detection ratio exceeds the specified threshold and save the sample data in a JSON file within the results directory.
4. Automatically download the filtered samples into the samples directory.
