Tracing stolen login credentials using OSINT – Investigating compromised login credentials in a forensically verifiable manner

In numerous data breaches in the past, login details such as email addresses and password hashes have been made public and, in some cases, compiled into searchable databases.

Enquire without obligation

Checking whether the login credentials of a relevant organisation or individual appear in such databases may be relevant in the context of cyber security investigations.

This is how an investigation into stolen login details works

Relevant email addresses or domains are checked against known, publicly accessible data breach databases using our tools. Any matches are documented, along with the source and, where known, the date of the underlying breach.

Why is the investigation into stolen login details relevant from a forensic perspective?

Evidence of compromised login credentials can be a key factor in explaining unauthorised access to a system.

Identifying affected accounts at an early stage also enables targeted countermeasures, such as enforced password changes.

Frequently Asked Questions
