Conducting subdomain enumeration for forensic purposes – Forensically identifying associated subdomains within a target infrastructure

The systematic identification of subdomains of a target domain can reveal additional systems within the same infrastructure, some of which may be less well protected or have been forgotten.

Enquire without obligation

This research may be relevant for gaining a more complete picture of the target infrastructure as part of existing IT forensic or security-related investigations.

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.

Our services

We carry out a structured subdomain enumeration for a relevant target domain and document the subdomains identified in a manner that is forensically traceable.

Typical areas of application

•Mapping of an organisation’s entire publicly visible infrastructure
•Supplementing IT security audits
•Identification of forgotten or unprotected test systems
•Support in investigating cyber security incidents
•Judicial and non-judicial expert reports
•Collaboration with IT security teams

This is how subdomain enumeration works

Using SpiderFoot and supplementary certificate and DNS lookups, subdomains associated with the target domain are systematically identified and their availability and technical status documented.

Why is subdomain enumeration relevant in a forensic context?

Less well-known or forgotten subdomains can reveal security vulnerabilities or additional systems of forensic interest within a target infrastructure.

A complete inventory of the infrastructure is often a prerequisite for a comprehensive technical investigation of a cybersecurity incident.

Frequently Asked Questions

Are active attacks carried out on the systems that are detected?+
No, we limit ourselves to the passive collection of publicly available, existing information.
Can every subdomain belonging to an organisation be found?+
No, subdomains that are not publicly advertised and are not recorded in certificate or DNS databases may not be included in the search.
Is the availability of any subdomains found checked?+
Yes, as part of passive research, we document which of the subdomains found appear to be currently accessible.
