Verifying email addresses using OSINT – Forensically tracing provided email addresses

Publicly available information can provide clues as to whether an email address is actually linked to a particular person or organisation.

Enquire without obligation

As part of existing cases, we carry out a systematic review of what publicly available information is available regarding a relevant email address.

How email address verification works

SpiderFoot is used to check the relevant email address against publicly available sources such as registration data, forums and data breach databases; any findings are documented along with their source and context.

Why is email address verification relevant in a forensic context?

Publicly available information relating to an email address can provide important clues as to the plausibility of a claimed identity.

The appearance of an email address in known data breaches can also be relevant when assessing a security risk.

Frequently Asked Questions

Is it possible to find out who an email address belongs to?+
Only to a limited extent via publicly available information; it is not always possible to identify them beyond doubt.
Are passwords from data breaches also being accessed?+
No, we simply record whether an email address appears in a data breach and, if so, in which one; we do not record the associated login details.
Is this search combined with a check for stolen login details?+
Yes, the two methods often complement each other as part of a comprehensive security audit.
