Introduction
Welcome to our walkthrough of the APIWizards Breach TryHackMe room! In this exercise, we take on the role of an external DFIR (Digital Forensics and Incident Response) specialist hired to investigate a security incident at APIWizards Inc., a company specializing in developing and hosting REST APIs. Suspecting a compromise in their production environment, APIWizards needs our expertise to identify and mitigate the breach.
Overview of the Investigation
Initial Investigation
We begin by investigating the compromised Linux server, identifying open ports, running processes, and examining logs to uncover signs of the breach. Understanding the initial access point is crucial in piecing together the attacker’s steps.
Gaining Initial Access
Next, we delve into the methods used to gain initial access to the server. By inspecting authentication logs and other indicators, we pinpoint how the attacker infiltrated the system.
Persistence Mechanisms
One of the critical aspects of the investigation is identifying persistence mechanisms the attacker might have established. This involves examining cron jobs, startup scripts, and other potential backdoors left by the intruder.
Further Actions and Final Target
As we progress, we analyze the attacker’s further actions, including any data exfiltration attempts, lateral movements within the network, and efforts to cover their tracks. The final objective is to identify the attacker’s end goal and the full scope of the breach.
Key Lessons Learned
- Identifying and mitigating security breaches: Practical techniques to investigate and secure compromised systems.
- Understanding persistence mechanisms: Recognizing how attackers maintain access and ensuring all backdoors are closed.
- Practical DFIR techniques: Applying digital forensics and incident response skills in a real-world scenario.
