Analyzing Windows Prefetch with Python

Overview

Windows Prefetch files (.pf) record application execution data including executable names, run counts, timestamps, loaded DLLs, and accessed directories. This skill covers parsing Prefetch files using the windowsprefetch Python library to reconstruct execution timelines, detect renamed or masquerading binaries by comparing executable names with loaded resources, and identifying suspicious programs that may indicate malware execution or lateral movement.

When to Use

• When investigating security incidents that require analyzing windows prefetch with python
• When building detection rules or threat hunting queries for this domain
• When SOC analysts need structured procedures for this analysis type
• When validating security monitoring coverage for related attack techniques

Prerequisites

• Python 3.9+ with windowsprefetch library (pip install windowsprefetch)
• Windows Prefetch files from C:\Windows\Prefetch\ (versions 17-30 supported)
• Understanding of Windows Prefetch file naming conventions (EXECUTABLE-HASH.pf)
