Service notice (October 2026): Virus.Exchange (virus.exchange) has shut down: the domain now redirects to vx-underground.org and its public sample bucket was removed. As of v0.2.3, virusxcheck runs in VirusTotal-only mode: VX lookups are disabled and a VirusTotal API key (VIRUSTOTAL_API_KEY) is required.

Overview

Virus.xcheck is a Python tool that checks file hashes against VirusTotal. It was originally built to cross-check hashes against the Virus Exchange database; Virus.Exchange has since shut down (see the service notice above), and from v0.2.3 the tool runs in VirusTotal-only mode. The tool can read hashes from a CSV file or accept a single hash from the command line.

Features

• Reads hashes from a CSV file or a single hash from the command line
• Checks each hash against the VirusTotal API (Virus Exchange lookups are disabled since the service shut down)
• Parallel processing for efficient handling of larger files
• Colorized, beautifully formatted output in the terminal
• Outputs the results in JSON or CSV format
• Command-line interface with multiple options
• API key management with .env file support
• Rate limiting to prevent API throttling
• Interactive HTML reports with visualisations

Requirements

• Python 3.8+

Installation

From PyPI (Recommended)

pip install virusxcheck

HTML Reports (Optional)

To generate interactive HTML reports, install with the report extra:

pip install virusxcheck[report]

This installs additional dependencies (plotly, pandas, jinja2) needed for HTML report generation.

From Source

git clone https://github.com/lewiswigmore/virus.xcheck.git
cd virus.xcheck
pip install -r requirements.txt

API Key Setup

1. Get an API key from VirusTotal
2. Create a .env file in the root directory with your API key:

   VIRUSTOTAL_API_KEY=your_api_key_here
   

   Alternatively, you can use the --save-config option to set your keys interactively:

   virusxcheck --save-config
   

Quick Start

pip install virusxcheck
virusxcheck --save-config            # Set up your API key
virusxcheck -s "sha256_hash_value"   # Check a single hash
virusxcheck -f hashes.csv -o out.json --html report.html  # Batch check with report

Usage

Note: After installing via pip install virusxcheck, you can use the virusxcheck command directly. If running from source, use python virusxcheck.py instead.

Execute the script from the command line with the following options:

Check a single hash

virusxcheck -s "hash_value"

Process multiple hashes from a CSV file

virusxcheck -f /path/to/your/hashes.csv

Save results to a file

virusxcheck -f /path/to/hashes.csv -o /path/to/results.csv
virusxcheck -s "hash_value" -o /path/to/results.json

Generate HTML report

virusxcheck -f /path/to/hashes.csv --html report.html

Disable colored output

virusxcheck -s "hash_value" --no-color

Test Examples

51919bdfd8bc0ebeec651efdd5d97dae7ad9532cb10f6efaa67c3dbc88ea7500

Testing with Sample CSV

Create a file test_hashes.csv with the above hashes and run:

virusxcheck -f test_hashes.csv --html results/report.html -o results/output.csv

Sample Output

When running the tool with the test hashes, you'll see output similar to:

VirusTotal API integration enabled
Processing: 100%|██████████████████████| 3/3 [00:00<00:00, 5.85it/s]
HTML report saved to results/report.html
Results saved to results/output.csv

The terminal will display detailed information about each hash, including:

• Detection status (found/not found)
• File metadata (size, type, first seen)
• Known filenames
• Tags associated with the sample
• VirusTotal detection statistics
• Download and reference links

Command-Line Arguments

• -s, --single: Single hash string to check
• -f, --file: Path to CSV file containing hashes
• -o, --output: Path to output file (CSV or JSON format)
• --html: Generate HTML report with interactive charts
• --save-config: Interactively save API keys to .env file
• --no-color: Disable colored output

Output Formats

Terminal Output

The tool produces a colored output in the terminal:

• Red for malicious files found in the database
• Green for clean files not found
• Yellow for warnings and errors
• Metadata display with file information, names, tags, and links

HTML Reports

The HTML reports include:

• Interactive charts showing detection rates and statistics
• File metadata and statistics
• Malware tag classification
• Detailed scan results from VirusTotal
