VirusTotal

A Google-owned online service that scans files, URLs, domains and IPs with many antivirus engines and reputation tools.

Definition

Analysts submit hashes or samples to see detection results, behavioral reports, relationships and community comments. Uploaded files are shared with security vendors and premium users, so sensitive files should not be uploaded; searching by hash avoids disclosure.

Example

Searching a suspicious attachment's SHA-256 on VirusTotal and finding 45 of 70 engines detect it.

Exam tip

Search by hash rather than uploading confidential files, which become available to others.
