Whose number is this A phone number is a strong selector: expensive to acquire, hard to change, and used as an account-recovery anchor almost everywhere. It is also the selector investigators get most wrong, because the metadata everyone quotes — the carrier — is frequently stale, and because a large share of numbers now belong to software rather than to a SIM in someone's pocket. Do not call or text the subject; that is contact, not research. Step 1 — Authorized scope Read ../../ETHICS.md . Wri...

Follow the Crypto Public chains are pseudonymous, not anonymous. Every transfer is permanently visible to anyone; what's missing is the mapping from address to human. So the whole game is attribution, and attribution almost always happens at an off-ramp — the point where value converts to fiat through a service that collected identity documents. Everything between the crime and the off-ramp is just plumbing you have to follow. The beginner error is treating a clustering heuristic's output as fac...

Hunt a handle Handle reuse is the cheapest strong link in OSINT: one string, checked in minutes, potentially tying a dozen platforms to one person. It is also the most over-trusted. Enumerators do not verify identity — they perform HTTP existence checks — and a hit list is a list of candidates , nothing more. The mistake that ruins these investigations is pasting the tool's output into the report. Enumeration is the cheap half; confirmation is the work. Step 1 — Authorized scope Read ../../ETHIC...

Geolocate from pixels Every photograph taken outdoors contains enough information to place it. The constraint is never the image; it is your patience and your reference knowledge. The beginner mistake is searching before inventorying. People see a mountain, type "mountain with two peaks" into a search box, and get nothing. The method is the opposite: extract every clue first, rank them by how much of the planet each one eliminates, and only then start searching — because the clue that pins the c...

What an email reveals An email address is usually the highest-value selector in an investigation: it carries a name, a domain, an account history, and a breach footprint.

Existence is the least interesting thing about it, it is the hardest thing to establish passively, and the techniques that establish it are the ones that expose you. Work the structure and the footprint first; treat validation as a bonus. Never send mail to the subject a...
