Better Together

There are multiple posts on the blog about what Volatility is and how to leverage the application tools. This post is about the strengths and weaknesses of Volatility and anti-virus/anti-malware applications, and how the solution to detect threats becomes so much more powerful when Volatility and anti-malware/anti-virus applications are combined.

Analyzing computer memory streams with volatility and using virus/malware software serve different purposes in detecting cyber threats, and they employ different methodologies and techniques.

  1. Volatility Analysis:
    • Purpose: Volatility analysis involves examining the contents of a computer’s volatile memory (RAM) to extract information about the system’s state at a given point in time. This is useful for incident response, forensics, and malware analysis.
    • Methodology: Volatility analysis tools like Volatility Framework provide a wide range of capabilities for analyzing memory dumps, including extracting running processes, network connections, open files, registry keys, and more. Analysts use this information to understand the behavior of a system, identify anomalies, and detect signs of compromise or malicious activity.
    • Key Features: It helps in identifying hidden or stealthy malware that might not be easily detectable by traditional antivirus software. Additionally, it can provide insights into the root cause of a security incident and aid in remediation efforts.
  2. Virus/Malware Software:
    • Purpose: Virus/malware software, also known as antivirus or endpoint protection software, is designed to prevent, detect, and remove malicious software from a computer system.
    • Methodology: Antivirus software relies on signature-based detection, heuristics, behavioral analysis, and other techniques to identify known malware strains and suspicious activities. It typically operates by scanning files on disk, monitoring network traffic, and analyzing behavior patterns of running processes.
    • Key Features: Antivirus software provides real-time protection by scanning files as they are accessed or executed, thereby preventing malware from infecting the system. It also offers features such as firewall protection, web browsing protection, and email scanning to safeguard against various attack vectors.

Key Differences:

  • Scope: Volatility analysis focuses on analyzing the contents of volatile memory to understand system activity and detect signs of compromise, while antivirus software primarily targets known malware signatures and suspicious behaviors across files and system activities.
  • Detection Mechanisms: Volatility analysis often relies on identifying anomalies and artifacts in memory dumps, whereas antivirus software uses a combination of signature-based detection, behavioral analysis, and heuristics to identify and mitigate threats.
  • Use Cases: Volatility analysis is commonly used in incident response, forensics, and malware analysis scenarios, whereas antivirus software is deployed for ongoing protection against a wide range of malware threats in real-time.
  • Complexity: Volatility analysis requires expertise in memory forensics and understanding of system internals, while antivirus software is typically designed for ease of use by end-users and IT administrators.

In summary, while both volatility analysis and antivirus software play crucial roles in detecting cyber threats, they differ in their approaches, scope, and use cases. Combining both approaches can provide comprehensive protection and threat intelligence for computer systems.

There is an application named Orochi. More information can be found here. I have been looking at the strengths and weaknesses of the application. First blush:

1, Extend security

2. Leverage golden images — see blog.

3. Replace database with something like Cassandra – need to scale and time series data.

4. Need to scale compute resources with Kubernetes.

5. Leverage AI models to build near real time reports.

I understand the value. I have the experience to do it. Now to get the time.
