In this lab, we will analyze a network capture file (PCAP) to investigate a security breach involving an Openfire messaging server. The organization’s security team has detected suspicious activity, and it is our task to determine the attacker's actions, uncover the exploited vulnerability, and identify the extent of the compromise. By leveraging network forensic tools such as Wireshark, we will dissect the captured traffic, trace unauthorized access attempts, and analyze the attacker's methodology. The attack appears to have involved unauthorized access to the Openfire admin console, followed by the installation of a potentially malicious component. Our analysis will focus on HTTP traffic, authentication attempts, file uploads, and command execution activity to reconstruct the sequence of events. Throughout this process, we will apply targeted Wireshark filters to extract meaningful evidence and determine how the attacker was able to escalate privileges and maintain access.
By the end of this investigation, we will have a clearer understanding of the security flaws that were exploited and the tools used in the attack. This lab serves as a good exercise in network forensics and incident response providing valuable insights into real-world exploitation techniques and their forensic detection.
