Course 36 - Windows Forensics and Tools | Episode 13: Decoding Registry Artifacts and Connection History
In this lesson, you’ll learn about: Windows USB forensics and how external device activity is tracked through the Windows Registry1. What Is Windows USB Forensics?USB forensics focuses on identifying and analyzing traces left by:
USB flash drives
External hard drives
Digital cameras and mobile storage devices
🔹 Key Idea Even after a device is unplugged or removed, Windows keeps permanent evidence of its connection.2. Why USB Devices Leave Forensic EvidenceWhen a USB device is connected, Windows automatically:
Logs device identity
Stores serial numbers
Records connection history
Links devices to specific users
🔹 Forensic Value This allows investigators to reconstruct:
Who used the device
When it was connected
What machine it was connected to
3. USBSTOR Registry Key (Device Identity Tracking)🔹 What it is A registry location that stores details of USB storage devices🔹 What it records
Vendor name (e.g., SanDisk, Kingston)
Product model
Unique serial number
👉 Key Insight This is the digital fingerprint of every USB device ever connected4. MountedDevices Key (Drive Letter Mapping)🔹 What it is Links physical USB devices to assigned drive letters (E:, F:, etc.)🔹 What it reveals
Which USB got which drive letter
How Windows mapped the storage at connection time
👉 Key Insight Helps reconstruct how the system interacted with external storage5. MountPoints2 Key (User-Level Evidence)🔹 What it is Stores per-user information about mounted devices🔹 What it reveals
Which user connected the device
Access history from user profile perspective
👉 Key Insight Connects USB activity directly to a specific Windows user account6. Forensic Significance of USB Artifacts🔹 What investigators can determine:
First time a device was plugged in
Last time it was used
Frequency of usage
Possible data transfer activity
👉 Key Insight USB history helps build a complete behavioral timeline of data movement7. USBDeview Tool (Practical Analysis)🔹 What it does Automatically extracts USB history from the system🔹 What it shows
Device name and model
Serial number
First/last connection time
Plug/unplug events
👉 Key Insight Turns raw registry data into readable forensic evidence8. Live System Analysis Considerations🔹 When analyzing active systems:
Registry must be extracted carefully
Evidence integrity must be preserved
Avoid modifying timestamps or device traces
👉 Key Insight Live analysis requires strict forensic discipline to avoid contamination9. Linking USB Devices to Real-World Activity🔹 Investigation process: USB device → Registry traces → User account → Timeline reconstruction👉 Key Insight This allows investigators to connect a physical device to a specific suspect machineKey Takeaways
Windows permanently records USB device history in the registry
USBSTOR stores device identity and serial numbers
MountedDevices maps USBs to drive letters
MountPoints2 links devices to specific users
Tools like USBDeview simplify forensic extraction
