VirusTotal API Setup Documentation

Overview

The VirusTotal API allows developers to access VirusTotal’s vast database of malware samples and threat intelligence data. With the API, you can retrieve information about malware samples, submit new samples for analysis, and access other features to help you detect and prevent malware threats.

Prerequisites

Before you start, make sure you have the following:

  • A VirusTotal account (free or paid)
  • A programming language of your choice (e.g., Python, Java, C#, etc.)
  • A development environment set up (e.g., IDE, text editor, etc.)

Step 1: Register for a VirusTotal API Key

  1. Go to the VirusTotal API website (https://www.virustotal.com/api/) and click on “Get an API Key”.
  2. Fill out the registration form with your email address, password, and other required information.
  3. Verify your email address by clicking on the link sent to you by VirusTotal.
  4. Once verified, you will receive an API key, which you will use to authenticate your API requests.

Step 2: Choose an API Endpoint

VirusTotal offers several API endpoints for different use cases. Choose the one that best fits your needs:

  • File Analysis: Submit a file for analysis and retrieve the results.
  • IP Reputation: Retrieve information about an IP address, including its reputation and associated malware.
  • Domain Reputation: Retrieve information about a domain, including its reputation and associated malware.
  • URL Reputation: Retrieve information about a URL, including its reputation and associated malware.

Step 3: Construct Your API Request

Once you’ve chosen an API endpoint, construct your API request using the following format:

https://www.virustotal.com/api/v3/{endpoint}?apikey={your_api_key}&{parameters}

Replace {endpoint} with the chosen API endpoint, {your_api_key} with your actual API key, and {parameters} with the required parameters for the endpoint.

For example, to submit a file for analysis:

https://www.virustotal.com/api/v3/files/submit?apikey=YOUR_API_KEY&file=example.exe

Step 4: Send Your API Request

Use your chosen programming language to send a GET or POST request to the constructed API endpoint. For example, in Python using the requests library:

import requests

url = "https://www.virustotal.com/api/v3/files/submit"
params = {"apikey": "YOUR_API_KEY", "file": "example.exe"}
response = requests.get(url, params=params)

print(response.json())

Step 5: Parse the API Response

The API response will be in JSON format. Use your chosen programming language to parse the response and extract the relevant information.

Troubleshooting Tips

  • Make sure to replace {your_api_key} with your actual API key.
  • Check the VirusTotal API documentation for specific parameter requirements and error handling.
  • Verify that your API request is correctly formatted and sent.
  • Check the VirusTotal API status page for any known issues or maintenance.
