Existing Security Appliances: CookieMiner Analysis
At Globomantics, an employee in the Marketing Department stated they’re receiving “unusual Sign In” alerts from various websites. You (the Security Analyst) must investigate their endpoint through Host-based (and Network-based) Intrusion Detection Systems. In this lab, you’ll investigate Tactics, Techniques, and Procedures (TTPs) that are inspired by the “CookieMiner” malware.

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
Malware: Initialization
In this challenge, you'll learn the core tenants of Intrusion Detection Systems: event collection, event analysis, and event visualization. You'll also deploy a piece of malware that you'll investigate in subsequent challenges.
-
Challenge
Malware: FIM Alert
In this challenge, you'll learn the basics of File Integrity Monitoring (FIM). Through this process, you'll leverage a FIM alert to inform a threat hunting session.
-
Challenge
Malware: Analysis
In this challenge, you'll do a deep dive into what triggered the FIM alert (i.e., malware.sh). Through this deep dive, you'll learn of a real-world attack that attempts to subvert Multi-Factor Authentication. You'll also learn how malware can evade detection mechanisms.
-
Challenge
HIDS Limitations
In this section, you'll learn the limitations of Host-based Intrusion Detection Systems.
-
Challenge
Suricata: Introduction
In this challenge, you'll shift your focus from host-based monitoring to network-based monitoring. In particular, you'll interface with Suricata, with a popular network monitoring tool. Earlier in the lab, you learned about Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS). Suricata is a tool that can act as an IDS and an IPS.
-
Challenge
Suricata: SimpleHTTP Alert
In this challenge, you'll review the Suricata rule that triggered the SimpleHTTP alert. You'll also understand how this alert could correlate to malware hosting activity!
-
Challenge
Suricata: Rule Creation
In this challenge, you'll learn how to leverage network events to create network-based rules. You'll then leverage this knowledge to create a rule that alerts on curl-based data exfiltration! Once you're done, you'll rerun the CookieMiner malware and see if the rule works!
-
Challenge
Suricata: Subverting Rules
In this challenge, you will learn how rules can be subverted.
