WhatsMyName Dataset Attribution & Licensing

WhatsMyName is built on top of the invaluable work of the open-source cybersecurity and OSINT community.

1. Upstream Dataset & Authors

The platform detection rules utilized by WhatsMyName are adapted from the WhatsMyName repository, originally created by Micah "WebBreacher" Hoffman in 2015 and maintained by hundreds of volunteer contributors worldwide.

2. Applicable License (CC BY-SA 4.0)

The upstream WhatsMyName dataset is licensed under the Creative Commons Attribution-ShareAlike 4.0 International License (CC BY-SA 4.0).

3. Adaptations Made by WhatsMyName

In accordance with the ShareAlike terms, our adapted and normalized dataset is publicly verifiable. WhatsMyName makes the following technical adaptations:

  • Schema Normalization: Raw upstream rules are transformed into a strict TypeScript/Python schema with canonical slugs and unique IDs.
  • SSRF & Host Security Hardening: Strict validation filters out private IP addresses, localhost, and non-HTTPS endpoints to prevent Server-Side Request Forgery.
  • Confidence Scoring: Automated calculation of confidence tiers (High, Medium, Low, Manual Review) based on signature robustness.
  • Local Overrides Layer: Custom annotations, display names, and verification advice stored in an isolated overlay.

4. How to Inspect Data or Submit Corrections

Anyone can inspect the normalized dataset in our repository under data/generated/sites.json.

To propose a new platform or fix a broken detection string, we strongly encourage submitting the change directly to the upstream WhatsMyName Issue Tracker, so the entire global OSINT community benefits from your discovery.
