🔍 Quick Study Guide: Memory Forensics
- 💡 Memory Forensics involves analyzing the contents of a computer's volatile memory (RAM) to gather digital evidence, often crucial for incident response and malware analysis.
- 🛡️ It's vital because critical data, such as running processes, network connections, user credentials, and malware artifacts, often resides only in RAM and disappears upon system shutdown.
- 🛠️ Popular open-source tools for memory analysis include the Volatility Framework and Rekall, which are used to parse raw memory dumps.
- 📈 Common artifacts extracted from RAM images include running processes (with PIDs), open network sockets, loaded DLLs, registry hives, and kernel modules.
- 💾 RAM acquisition methods, such as using tools like FTK Imager Lite, WinPMEM, or LiME for Linux, must be performed carefully to minimize system alteration and preserve evidence integrity.
- 🚫 Unlike traditional disk forensics, memory forensics deals with highly volatile data, making timely and proper acquisition paramount.
- 🚨 Key challenges include the volatility of data, the large size of memory dumps, and the need for specialized knowledge to interpret findings accurately.
