## Resource

In this lesson, you’ll learn about: Windows Registry artifacts and UserAssist forensics1. Why Registry Artifacts Matter The Windows Registry stores hidden traces of user activity Investigators use it to reconstruct: User behavior Application usage System timelines 🔹 Key Idea Every click and execution leaves a forensic footprint 2. Common Digital Footprints in Windows🔹 Types of artifacts Internet browsing history Email attachments Skype / communication logs Recently used files (MRU lists) Executed programs 👉 Key Insight: Even deleted actions often remain in registry traces 3. The UserAssist Key🔹 What is it? A Windows Registry key that tracks program execution history 🔹 What it records Application name Run count (how many times launched) Last execution timestamp Usage frequency 👉 Why it matters: Shows what a user actually ran, not just what exists on disk 4. ROT13 Obfuscation🔹 What Windows does UserAssist entries are encoded using a simple cipher: ROT13 cipher 🔹 Purpose Obscures readable program names Prevents casual inspection 👉 Important Insight: It is not encryption, just basic encoding 5. Decoding UserAssist Data🔹 Tools used by investigators UserAssistView Magnet Forensics tools 🔹 What they do Decode ROT13 values Convert registry entries into readable format Display execution history clearly 6. Building a Forensic Timeline🔹 What investigators reconstruct When programs were opened How often they were used Sequence of user actions 🔹 Why it matters Helps establish: Intent Behavior patterns Possible malicious activity 7. Investigative Value of UserAssist🔹 What it reveals User activity patterns Application usage frequency Time-based behavior analysis 👉 Key Insight: It helps answer: “What did the user actually do on the system?” 8. Forensic Importance Supports legal invest…
