Forensic Analysis of Windows PowerShell Artifacts – Tracing Commands and Activities

PowerShell is one of the most important administrative tools in Windows. Administrators use it for automation and system administration, whilst it is also frequently misused in cyber-attacks. Depending on the configuration, PowerShell logs, history files and other artefacts can provide valuable insights into the commands executed and system activities.

Enquire without obligation

A professional analysis is never carried out in isolation. Only by correlating data with event logs, Prefetch, Amcache, registry artefacts, WMI and other digital traces is it possible to arrive at a reliable technical assessment.

This is how the analysis works

Once a forensic image has been created, all relevant PowerShell artefacts are analysed and correlated with other Windows artefacts.

Why are PowerShell artefacts important?

PowerShell is capable of making extensive changes to the system. Analysing existing artefacts often makes it possible to reconstruct administrative or security-related activities. However, their significance only becomes apparent when all relevant digital traces are analysed as a whole.
