Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"macrocyber-macrocyber","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

Attributed to the source that supplied each field. Treated as claims, not facts.
Passive external attack-surface scanner that returns a signed, exploitability-graded exposure claim. MacroCyber maps your external attack surface in real time and is built for the AI era: it finds the exposures AI-built software leaks (databases left open, leaked AI and model keys, exposed MCP servers and agent endpoints, open vector stores) alongside the classic gaps (spoofable email, takeover-prone subdomains, missing headers, weak TLS). It reports only observable facts, proves every finding, and ranks what an attacker, increasingly an autonomous agent, reaches first.
Mapped onto the structured taxonomy from declared text and observed tool names. Confidence shown for derived entries.
