Lab Description

In this hands-on lab, you are placed in the role of a network analyst responding to alerts of suspicious activity within your organization’s environment. Your mission is to investigate potential indicators of compromise tied to the Log4j vulnerability by analyzing network traffic using Wireshark.

You begin by capturing live packets and filtering HTTP traffic, zeroing in on POST requests and inspecting headers and payloads for the signature "jndi:ldap" string - an indicator of Log4Shell exploitation attempts. You also examine user-agent strings for anomalies that could hint at scanner tools or attacker-controlled clients. As you progress, your attention broadens to encompass TCP conversations, DHCP and Kerberos protocol exchanges, and FTP command inspection, giving you insight into the state of internal systems and any clear-text data risks.

By the end of the lab, you will have documented instances of potentially malicious activity and gained the skills needed to monitor and analyze complex protocol interactions. These capabilities will help your organization prevent or contain security breaches stemming from misconfigured services or unpatched software.
