The VirusTotal API is a versatile and powerful tool that can be utilized in so many ways. Although it is commonly used for threat intelligence enrichment and threat analysis, the potential uses are virtually limitless. The latest version, VirusTotal API v3, is continuously updated with new features to enhance its capabilities with every new release.

With this post we want to help you understand its potential and, in case you are a VT API veteran, help you migrate from API v2 to API v3 to unleash its full potential.

To simplify the process of adopting and migrating to VirusTotal API v3, we have updated the official documentationwith a specific section dedicated to this purpose. We also created a GitHub repository with working examples. In the next few weeks we will host a webinar showing you cool use cases you can implement with VT API, so stay tuned!
Why use VT API v3?
The migration guide describes in detail most API v3 benefits, including:
  • Endpoints for all VirusTotal products and scanners. VT users can access all of VirusTotal’s tools through a single API, simplifying the integration process.
  • User and group management helping administrators to automate managing access and accounts, as well as tracking usage across your team.
  • Extra relevant information for file, URL, domain and IP reports. VT API v3 provides additional information for all file, URL, domain and IP reports, including metadata and context.
  • REST-based, with predictable, resource-oriented URLs. VirusTotal API v3 uses a RESTful architecture, following a standard set of design principles for building web services with HTTP methods accessed through predictable, resource-oriented URLs, making it easier to use and integrate with other tools.
  • MITRE related tactics and techniques seen in file behavior. API v3 provides information on TTPs used by malware samples, as defined by the MITRE ATT&CK framework. This helps understanding the potential impact of a sample and how to respond to any threats.
  • More extensive documentation and code examples based on the Python module. V3 has more extensive documentation and code examples which make it easier for users to get started with the API and integrate it into their workflows.
