Classify IP addresses as internet scanners (benign/malicious) or targeted attackers — filters noise from security alerts.
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
# GreyNoise — Internet Scanner Intelligence
GreyNoise collects and analyses internet-wide scan traffic. It tells you whether an IP hitting your firewall is a known mass-scanner (benign research tool or malicious crawler) versus a targeted attacker — helping SOC teams filter out internet noise from real threats.
**Community tier:** The `/v3/community/{ip}` endpoint works with limited volume even without a key. Set `GREYNOISE_API_KEY` for higher rate limits.
## When to Use
- An IP triggers a firewall rule and you want to know if it is just background internet noise
- SOC triage: is this alert a known scanner or a targeted attack?
- Filter false positives from SIEM before escalating an alert
- User asks "is this IP a scanner?", "is this noisy traffic?", "is IP X benign?"
## How to Use
### Check if an IP is a known internet scanner
```powershell
$ip = "71.6.135.131"
$headers = @{}
if ($env:GREYNOISE_API_KEY) { $headers['key'] = $env:GREYNOISE_API_KEY }
$result = Invoke-RestMethod -Uri "https://api.greynoise.io/v3/community/$ip" -Headers $headers
Write-Host "IP: $($result.ip)"
Write-Host "Noise: $($result.noise)" # true = mass-scanner

How to install
mdr add taracodlabs/aiden/greynoise@sha256:3f1c321565ccc398The 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.
