Reveal Walkthrough

As an incident responder, your main objective is to understand the context of the incident being investigated. This includes gathering details about the incident's nature, affected systems, timeline of events, and potential impact. A clear understanding of these factors is essential for effective analysis and response, helping you address the root cause and mitigate future risks.

Investigation Scope

In this scenario, we have an alert from your SIEM solution that has flagged unusual activity on an internal workstation. Due to the sensitive financial data at risk, immediate action is essential to prevent potential breaches. We’ve been provided with a 2GB memory dump from one of the compromised machines as an artifact for this investigation.

Tools used

The recommended tool for this analysis is Volatility 3, a memory forensics framework widely used for examining RAM dumps in digital investigations. Here’s an overview of how Volatility 3 operates:

How Volatility 3 Manages Memory Dumps

• Loading and Identifying the Memory Image: Volatility 3 starts by loading the memory dump and automatically identifying the operating system profile. This OS profile allows Volatility to interpret specific memory structures and data layouts unique to that OS version.
• Using Symbol Tables: Volatility 3 utilizes symbol tables as comprehensive maps of OS-specific data structures, which are crucial for accurately parsing memory layouts, even across different OS versions.

How Volatility 3 Uses Plugins for Data Parsing

• Plugin Execution: Each Volatility 3 plugin performs a specific
