VirusTotal
Online service that scans files, domains, IPs, and URLs against dozens of antivirus engines.
Technical Architecture & Overview
VirusTotal aggregates antivirus verdicts, sandbox results, and URL analysis for submitted artifacts, and it correlates them with prior submissions from the community. Free access covers manual scans and a limited API, while VirusTotal Intelligence and Enterprise add retrohunt, livehunt, and graph analysis over the collected corpus. Google owns the service, and submissions on the free tier are shared with participating vendors.
Targeted Technical Use Cases
Checking whether a hash, URL, or domain is already known malicious before deeper analysis.
