Verify contact details using OSINT – Conduct a forensically verifiable check of the contact details provided

In the context of existing cases, it may be relevant to check whether the contact details provided, such as email addresses or telephone numbers, are consistent with publicly available information.

Enquire without obligation

As part of our investigation into existing issues, we carry out a structured check to determine whether publicly available sources support or contradict the contact details provided.

This is how a contact details match is carried out

The relevant contact details are cross-checked against publicly available sources using SpiderFoot and structured manual research; matches and discrepancies are documented.

Why is the matching of contact details relevant in a forensic context?

Contradictory or missing contact details can be a key indication of deliberate attempts to conceal one’s identity.

The documented comparison also helps to ensure the traceability of testing processes for internal and external bodies.
