Forensic analysis of Windows WMI – Understanding persistence mechanisms and system activities

Windows Management Instrumentation (WMI) is a central management platform for the operating system. Administrators and numerous applications use WMI for system management and automation. At the same time, WMI is frequently used by attackers to establish long-term persistence or to execute commands undetected.

Enquire without obligation

In the context of a professional IT forensic investigation, WMI artefacts are never assessed in isolation. Only by correlating them with registry artefacts, event logs, scheduled tasks, services, prefetch files and other digital traces is it possible to carry out a reliable technical assessment.

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 WMI repositories, event filters, event consumers, filter-to-consumer bindings and other WMI artefacts. The results are cross-referenced with additional Windows artefacts and fully documented.

Typical areas of application

•Incident Response
•Malware and ransomware investigations
•Analysis of persistence mechanisms
•Reconstruction of administrative activities
•Investigation of system tampering
•Expert reports for the courts

This is how the analysis works

Once a forensic image has been created, all relevant WMI artefacts are examined. This is followed by a technical assessment in the context of other digital traces from the system.

Why are WMI artefacts important?

WMI can be used both for legitimate system administration and for malicious persistence mechanisms. Only a comprehensive analysis of all relevant artefacts enables a proper and legally sound assessment.
