A digital forensics investigation requires analysis of a compromised system's physical memory. Which of the following tools should the forensics analyst use to complete this task?

The Volatility Framework is the industry-standard, open-source toolset specifically designed for the analysis of volatile memory (RAM). When a system is compromised, many artifacts of the intrusion, such as running malicious processes, network connections, injected code, and encryption keys, may only exist in physical memory and not on the disk. Volatility allows a forensics analyst to extract and analyze these ephemeral artifacts from a memory dump, which is a critical step in understanding the scope and nature of an attack. It is the most specialized and appropriate tool for the task described in the question.

A. Autopsy: A digital forensics platform primarily used for hard drive and file system analysis, not for in-depth volatile memory forensics.
B. FTK: A comprehensive suite for disk imaging and analysis. While it has some memory analysis features, it is not as specialized as Volatility.
D. Wireshark: A network protocol analyzer for capturing and inspecting network traffic (data in transit), which is unrelated to analyzing physical memory (data in use).
E. CAINE: A complete forensic environment (Linux distribution) that bundles various tools, including Volatility, but it is the platform, not the specific analysis tool itself.
