Getting Started in the Lab Environment
Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!
-
Challenge
Triage and Collect Artifacts
To start things off, you will conduct an incident response investigation on a compromised PostgreSQL database server by collecting and analyzing forensic artifacts. You will extract PostgreSQL logs and audit logs, transfer them to an analytics server, and use pgBadger to generate reports that reveal unauthorized access and malicious activities.

Challenge
Forensic Analysis and Root Cause Determination
In this challenge, you need to analyze the collected artifacts using pgBadger and Auditd. Your goal is to determine how the attacker exploited the database, what actions were taken, and whose credentials were compromised.
-
Challenge
System Recovery and Fix Implementation
To finish up, you will implement system recovery measures to restore the integrity of the compromised PostgreSQL database. Your tasks include removing unauthorized modifications, revoking excessive privileges, securing credentials, and hardening network access. By the end of this challenge, you will have mitigated the attack’s impact, and ensured the database environment is secure.
