Identifying data breaches on the Dark Web using OSINT – Conducting forensic investigations into published data breaches

Stolen data sets are regularly published or offered for sale on relevant dark web forums and specialised platforms; identifying these may be relevant in the context of a cyber security incident.

Enquire without obligation

As part of our work on existing cases, we carry out structured investigations to determine whether data from an affected organisation appears in such sources, and we document the results in a manner that is forensically verifiable.

Why LanCologne?

Since its foundation, LanCologne has specialised in professional IT forensics. Our staff have decades of experience in the field of information technology and assist companies, solicitors, private individuals and, on a regular basis, the courts in the technical investigation of complex digital matters.

Our OSINT investigations are always carried out as a complementary component to existing IT forensic, legal or internal corporate enquiries. Every step of the investigation and every piece of digital evidence found is documented and, where technically possible, archived to ensure traceability even if the original online content is subsequently altered or deleted.

How a dark web data breach investigation is carried out

Using our tools, we systematically search relevant forums, marketplaces and data leak databases for references to the organisation in question and, where accessible, document the data records found, including timestamps and source references.

Why is investigating data breaches on the dark web relevant from a forensic perspective?

Early detection of a publicised data breach can be crucial for taking appropriate countermeasures and complying with statutory reporting obligations.

The documented extent of a leak can also serve as an important basis for assessing the actual extent of the damage.

Frequently Asked Questions
