Course 36 - Windows Forensics and Tools | Episode 4: From Acquisition to Volatility Analysis

In this lesson, you’ll learn about: memory forensics and RAM analysis1. Why Memory Forensics Matters

• RAM (volatile memory) is one of the most valuable forensic sources
• It contains data that disappears after shutdown

🔹 What RAM can reveal

• Running processes
• Active network connections
• Command history
• Encryption keys
• Malware behavior in real time

👉 Key Idea:

• If disk is “history,” RAM is live truth

2. Memory Acquisition (Capturing RAM)🔹 What is memory acquisition?

• Creating a snapshot of physical RAM for analysis

🔹 Common Tools

• DumpIt
  • Simple one-click RAM dump tool
  • Used widely in field forensics
• NotMyFault
  • Forces system crash
  • Generates full kernel memory dump

👉 Key Tradeoff:

• DumpIt → fast and simple
• Crash dump → deeper but disruptive

3. Types of Memory Evidence🔹 What investigators look for

• Process objects
• Suspicious threads
• Injected code
• Hidden malware artifacts

🔹 Why it’s important

• Malware often exists only in memory
• Disk analysis alone may miss it

4. Memory Forensic Techniques🔹 String Searching

• Look for:
  • Passwords
  • URLs
  • Commands
  • API keys

🔹 Process Inspection

• Identify:
  • Legitimate processes
  • Suspicious or orphaned processes

🔹 Thread Analysis

• Detect:
  • Code injection
  • Hidden execution paths

5. Deep Analysis with Volatility🔹 What is Volatility?

• A powerful memory forensics framework for analyzing RAM dumps

🔹 Key Capability

• Extracts structured evidence from raw memory images

6. Core Volatility Commands🔹 pslist

• Shows active processes
• Based on system process list

🔹 psscan

• Finds hidden or terminated processes
• Scans memory directly

🔹 psxview

• Cross-checks multiple process sources
• Detects rootkits and hidden malware

👉 Key Insight:

• If a process appears in psscan but not pslist, it may be hidden

7. OS Profiling

• First step in analysis is identifying:
  • Operating system version
  • Memory structure layout

👉 Why it matters:

• Correct profile = accurate results in Volatility

8. Malware Detection in Memory🔹 What investigators look for

• Injected DLLs
• Suspicious network activity
• Hidden execution threads

🔹 Key Concept

• Malware often hides better in RAM than on disk

9. Reporting Findings🔹 Output process

• Extract evidence
• Convert results into structured reports
• Document every forensic step

👉 Goal:

• Make results repeatable and legally defensible

Key Takeaways

• RAM is the most dynamic and valuable forensic source
• Memory acquisition must be done carefully to preserve evidence
• Tools like DumpIt and crash dumps capture volatile data
• Volatility enables deep inspection of memory structures
• Cross-checking process lists helps detect hidden malware

Big PictureMemory forensics helps you:👉 Move from live system behavior → hidden system truthMental Model

• Capture RAM → Identify OS → Analyze processes → Detect anomalies → Report findings
