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
Detecting Suspicious Login Activity
Globomantics Intrusion Detection System (IDS) flagged unusually high-rate traffic to the HTTP File Server. You have to analyze the network traffic to identify patterns of suspicious login attempts, determine whether unauthorized access occurred, and review additional details, such as the brute force transfer rate, to understand the attack pattern better.

Challenge
Tracing Sensitive File Access and Data Exfiltration
Globomantics HTTP File Server logs show requests for specific files containing sensitive information, such as FTP credentials. Your task is to analyze the network traffic, locate the request for the file, and extract its contents to confirm if sensitive data was accessed.
-
Challenge
Investigating Bypassed Restrictions and Unauthorized FTP Access
Globomantics IDS detected anomalous ICMP and SSH activity, followed by FTP transfers. Your task is investigating the ICMP pings, analyzing SSH traffic, and identifying FTP data transfers that indicate successful unauthorized access. Using the FTP credentials discovered earlier, the attacker downloaded sensitive files, which you must uncover and analyze.
