Summary
In this lesson, you’ll learn about: Windows Prefetch and forensic execution tracking1. What is Windows Prefetch? A Windows performance feature designed to: Speed up application startup Reduce disk access time 🔹 Key Idea It becomes a forensic artifact that records program execution 2. How Prefetch Works Windows monitors the first seconds of an application launch It records: Files accessed Execution behavior patterns 👉 Result: A cached “startup map” is created for faster future runs 3. Prefetch File Structure🔹 Naming Format Application name + hash The hash is an 8-character hexadecimal value 🔹 Purpose of the Hash Derived from the application path Helps differentiate: Same program in different locations 👉 Key Insight: Same executable in different folders = different Prefetch file 4. Forensic Value of Prefetch🔹 What investigators can determine When a program was executed How many times it was run Whether it ran from unusual locations 5. The “Who, What, When” of Forensics🔹 Key Questions Answered Who: Which program was executed What: Which executable was run When: Last execution timestamp 👉 Important: Prefetch is one of the strongest execution evidence sources in Windows 6. Detecting Evidence Tampering🔹 Critical Insight Presence of cleanup tools is itself evidence 🔹 Example If a wiping tool appears in Prefetch: It proves the tool was executed 👉 Key Idea: “Trying to hide evidence” becomes evidence itself 7. Hidden Activity Discovery🔹 Prefetch can reveal: Hidden directories External storage usage Encrypted container activity 🔹 Example targets TrueCrypt volumes External USB drives Obfuscated folders 8. System Evolution🔹 Related Windows Technologies Superfetch ReadyBoost 👉 Purpose: Improve system responsiveness and memory usage 9. Registry Control of Prefetch🔹 Key Concept Prefet…
