IT Forensics – Windows

Forensic analysis of the Windows swapfile.sys – Evaluating additional memory artefacts

In addition to pagefile.sys and hiberfil.sys, Windows on modern systems also uses the swapfile.sys file. It is used in particular to manage certain memory areas of modern Windows applications and may – depending on the system status and usage – contain further information relevant to forensic analysis.

Enquire without obligation

In the context of a professional IT forensic investigation, the swapfile.sys is never examined in isolation. Only by analysing it in conjunction with memory dumps, pagefile.sys, hiberfil.sys, registry data and other Windows artefacts is it possible to carry out a thorough technical assessment.

This is how the analysis works

Once a forensic image has been created, the swapfile.sys is identified and analysed alongside other memory and file system artefacts.

Why is swapfile.sys important?

It may contain supplementary information that is not present, or is no longer present in full, in other archival artefacts. However, its significance only becomes apparent when evaluated as part of the overall analysis.
