Forensic analysis of the Windows DNS cache – tracing network activity

The Windows DNS cache stores information about recently resolved domain names. As part of an IT forensic investigation, this data can provide clues about network communications, services used or access to specific systems. The information available depends on the system’s state and the specific circumstances of the individual case.

Enquire without obligation

A professional analysis is never carried out in isolation. It is only by correlating the data with event logs, browser artefacts, firewall logs, the Windows Registry and other digital traces that a reliable technical assessment can be made.

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.

The examination is carried out exclusively on a forensic copy or a forensic image. The original evidence remains unchanged and is stored in a manner that preserves its evidential integrity.

Our services

We analyse DNS cache entries, assess their temporal relationships and cross-reference the results with other network and Windows artefacts. All stages of the investigation are documented in a way that allows for full traceability.

Typical areas of application

Incident Response
Analysis of network activity
Investigation into potential malware
Reconstruction of user activities
Data theft
Expert reports for the courts

This is how the analysis works

Once a forensic image has been created, the relevant DNS artefacts are analysed and correlated with other digital traces. This is followed by a technical assessment of the results.

Why is the DNS cache important?

The DNS cache can provide additional clues regarding resolved domain names and network activity. However, its significance only becomes apparent when all relevant digital traces are analysed together.
