OSINT e inteligência

A inteligência de fontes abertas relaciona informação pública com uma pergunta concreta. Verifique origem, data, local e independência das fontes; distinga indícios de confirmações e registe os limites da investigação.

Guias práticos

Verify a claim using open sources

How do you verify an open-source claim? Define a precise assertion, trace its earliest publication and seek evidence of different kinds. The expected output is an evidence record covering the claim, original URL, event date, access date, context, supporting material, contradictions and justified confidence. Missing information does not automatically establish that an event did not happen; repetition is not independent confirmation.

FIRST · Traffic Light Protocol

Indicate who may receive redistributed information.

 TLP 2.0 uses RED, AMBER, GREEN and CLEAR; AMBER+STRICT restricts sharing to the recipient organisation. Labels must not be translated. Keep the marking with the information and check recipients before forwarding. Ask the source to clarify any ambiguity.

Aprofundar o método →

 TLP is neither a formal classification nor a reuse licence. It does not guarantee content accuracy.
C2PA · Content Credentials

Describe and verify certain content provenance information.

 C2PA specification 2.4 defines manifests, assertions and cryptographic binding mechanisms associated with media. Examine what the manifest asserts, who signed it and whether validation succeeds. Test preservation after transformations and distribution.

Aprofundar o método →

 Validated provenance does not establish the truth of a scene. Absence of a manifest does not demonstrate a fake.
ICANN · Registration Data Lookup

Consult available domain registration information.

 RDAP is the registration data access protocol. ICANN Lookup provides access to available public registration data. Keep the exact domain, consultation date and result. Distinguish registrar, technical service and the entity operating a website.

Aprofundar o método →

 Data may be redacted or limited. Domain information alone cannot attribute content or an operation to a person.

Separate technical trace, source and judgment

Verifiable provenance helps describe a file’s history. Analysts must still check contextual claims and the independence of documents repeating them.

  • Associate each claim with its exact asset and source.
  • Trace repetitions to origins before describing corroboration.
  • Retain uncertainty and information that could change the judgment.

OSINT: preservar provas

As notas detalhadas desta edição estão disponíveis em inglês.

Usable intelligence retains the trail of its supporting material

Connect each conclusion to sources, preserved objects and working transformations. Custody complements corroboration; it does not turn unverified information into established fact.

  • Describe observed scope, capture limits and date uncertainty.
  • Separate preserved reference, technical copy and assessment extract.
  • Expose unconfirmed transfers and analytical assumptions.

Reconcile collection identities and revisions

An exit inventory or OSINT collection can reach the last page while missing an object or mixing its revisions. A total alone does not establish that expected data is present.

  • Fix order, scope and consistency reference before reading.
  • Compare IDs and revisions beyond row counts.
  • Retain discrepancies and recovery decisions when the reference changes.
