VirusTotal: check file/URL/domain/IP against 70+ AV engines.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# VirusTotal — Threat Intelligence
VirusTotal aggregates results from 70+ antivirus engines and threat intelligence feeds. Check file hashes, URLs, domains, and IP addresses for known malware, phishing, and suspicious activity.
**Requires:** `VIRUSTOTAL_API_KEY` — free at https://www.virustotal.com/gui/my-apikey (4 req/min on free tier).
## When to Use
- User has a file hash and wants to know if it is malware
- User has a suspicious URL and wants a reputation check
- User is investigating an incident and needs threat context for a domain or IP
- User asks "is this hash malicious?", "check this URL", or "is this domain flagged?"
- SOC/IR workflow: triage IOCs (indicators of compromise) quickly
## How to Use
### Check a file hash (MD5, SHA-1, or SHA-256)
```powershell
$hash = "44d88612fea8a8f36de82e1278abb02f" # EICAR test file
$key = $env:VIRUSTOTAL_API_KEY
$url = "https://www.virustotal.com/api/v3/files/$hash"
$result = Invoke-RestMethod -Uri $url -Headers @{ "x-apikey" = $key }
$stats = $result.data.attributes.last_analysis_stats
Write-Host "File: $($result.data.attributes.meaningful_name)"
…Read the whole file at its exact version.
How to install
mdr add taracodlabs/aiden/virustotal@sha256:78b93534e0ff7777The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
