How to Set Up a Network Research Lab for Malware Analysis

TLDR:

  • Setting up a network lab for malware analysis involves using a virtual machine within a local VPN.
  • Analyzing vulnerabilities like CVE-2024-21413 and crafting proof-of-concepts can help in identifying indicators of compromise.

Security researchers can set up a network research lab for malware analysis by creating a controlled environment using a virtual machine within a local VPN. This article discusses the steps involved in analyzing vulnerabilities such as CVE-2024-21413 and crafting proof-of-concepts to identify indicators of compromise.

Analyzing CVE-2024-21413:

One method discussed in the article involves clicking a malicious link in an email to exploit a vulnerability in Outlook, leaking NTLM hashes during SMB authentication attempts. By using tools like Impacket within the VPN, researchers can record network traffic to identify IoCs unique to the exploit and draft detection rules for future attacks.

The article also explains how to setup an OpenVPN server as an attacker’s entry point and integrate virtual machines into the local network for further analysis. Creating fake SMB servers using the Impacket library and crafting emails with malicious RTF files are highlighted as potential attack methods.

Security analysts can use tools like ANY.RUN to analyze suspicious activities and create detection rules, such as monitoring for NTLM hash leakage in SMB traffic on the external network. By meeting specific conditions, these rules can flag potential exfiltration attempts for further investigation.

Overall, setting up a network research lab for malware analysis involves creating a secure environment to analyze vulnerabilities, craft proof-of-concepts, and develop detection rules to enhance network security.
