useOSINT

Router for investigation work. Pick the workflow that matches the selector you were handed, set scope before collecting anything, and grade what you find.

Sources

Your knowledge of breach corpora, data-broker coverage, registry endpoints and platform APIs may be outdated. Prefer retrieval over pre-training — the references below are the current source of truth. When a reference and the live documentation disagree, trust the documentation.

Step 1 — Scope before you collect

Every workflow here assumes a documented lawful basis. Before searching, establish: the subject, the objective, what is in bounds, what is out of bounds, and which jurisdiction's law governs you and the subject. Read ../../ETHICS.md.

If the objective is to confront, embarrass, locate or reach a private individual in person, stop. That is not what these workflows are for.

Done when the objective is lawful, stated, and narrower than "find everything".

Step 2 — Route on the selector you hold

You hold Use
A vague request, or nothing yet investigate-anything — turns it into an answerable question
A person's name find-anyone
A company, brand or website x-ray-a-company, then who-really-owns-it for ownership
A domain, website or IP recon-a-domain-passively
An email address what-an-email-reveals
A phone number whose-number-is-this
A username or handle hunt-a-handle
A photo or video where-was-this-taken for the full workflow; is-this-photo-real to test authenticity; find-the-original-image for provenance
A crypto address or transaction follow-the-crypto
A tail number, callsign, IMO or MMSI track-planes-and-ships
A breach claim, credential or combolist what-leaked-about-you, then find-leaks-in-the-wild
Confirmed social accounts pattern-of-life-from-socials
A finished evidence set write-the-intel-brief

Business framings map onto the same workflows:

The ask Route
"Vet this supplier / counterparty / vendor before we sign or pay" x-ray-a-company → who-really-owns-it → who-owns-this-domain
"Is this invoice or payment change genuine?" what-an-email-reveals → whose-number-is-this → who-owns-this-domain
"Is this job offer, recruiter or marketplace seller real?" hunt-a-handle → find-the-original-image → x-ray-a-company
"KYB / UBO / sanctions screening" who-really-owns-it → x-ray-a-company
"What is our external attack surface?" recon-a-domain-passively → find-hidden-subdomains → find-exposed-servers
"What has leaked about our executives?" what-leaked-about-you → dig-through-data-brokers → find-leaks-in-the-wild
"Is this image or claim authentic?" is-this-photo-real → find-the-original-image → geolocate-from-pixels

Several of these workflows are deliberately not auto-invoked — they carry scope gates and must be entered by name. Naming them from here is the intended path.

Step 3 — Work cheapest and least intrusive first

Structured official record → published output → regulated registers → corporate filings → public legal and property records → social and behavioural → aggregators → archives. Do not start with data brokers; they hand you plausible wrong answers before you have any way to reject them.

Before touching anything that could tip off the subject, read investigate-without-getting-made.

Step 4 — Grade before you report

Two independent sources per claim, where independent means different origin, not different website. Grade the identity attribution separately from the claim itself — a record can be entirely genuine and still not be your subject. Record negative findings; an absence is a finding, not a gap to hide.

Hand off to write-the-intel-brief.

Where this goes wrong

  • Skipping scope. The most common failure is collecting first and justifying later.
  • Name collision. Never search a name alone; bind it to a second selector first.
  • Aggregators laundering each other. Three brokers agreeing is one source.
  • Over-trusting a photo match. A shared image proves shared images, not shared identity.
  • Treating a sparse footprint as concealment. It usually means a private person, a non-English footprint, or closed registries.
