What is Memory Forensics?
Memory forensics is the process of examining a system's RAM (Random Access Memory) — whether live or captured — to uncover malicious activity or Indicators of Compromise (IOCs). The goal is to detect stealthy malware that evades traditional signature-based antivirus and disk-level detection tools.

• 🖥 Fileless Malware: Executes entirely in memory, leaving no trace on disk.
• 🖥 Rootkits: Malware that manipulates kernel functions to hide itself.

Why is Memory Analysis Crucial for the Blue Team?

• ⏺ Detect Advanced Threats: Many APTs reside solely in memory.
• ⏺ Live Attack Analysis: Enables understanding of real-time attacker behavior.
• ⏺ Forensic Evidence Collection: Supports post-incident investigations.

🛠 Essential Memory Forensics Tools

1. Volatility: The most popular open-source memory analysis framework.
2. Rekall: An advanced alternative to Volatility with similar capabilities.
3. FTK Imager: Used to acquire forensic-grade memory and disk images.
4. WinDbg: A Microsoft debugger for crash dump and memory analysis.

Memory Analysis Workflow

1. Memory Acquisition:
   Use trusted tools like DumpIt or Belkasoft Live RAM Capturer.
   Ensure forensic integrity — avoid altering memory during capture.
2. Memory Analysis with Volatility:
   Load your image and run key plugins:
   
   

       volatility -f memory.dump pslist
       # → Lists active processes
       volatility -f memory.dump malfind
       # → Detects injected malicious code
       volatility -f memory.dump netscan
       # → Scans for suspicious network connections

3. Search for IOCs:
   ⏺ Suspicious DLLs loaded abnormally
   ⏺ Process Hollowing: Legitimate processes replaced with malware code
4. Document Your Findings:
   Generate a detailed forensic report for IR teams with:
   ⏺ All anomalies and IOCs
   ⏺ Screenshots of memory structures
   ⏺ Plugin outputs and context analysis

Real-World Attacks Uncovered via Memory Forensics

• Fileless Attacks: Code injected via PowerShell or WMI
• Lateral Movement: Evidence of credential theft, RDP activity
• Memory Injection: Mimikatz stealing credentials from LSASS
