»Hunting Linux Malware for Fun and Flags«
2019-05-16, 10:30–12:30, Workshop 3

Fun introduction to Linux malware analysis and incident response. Trainees get root access to compromised Linux servers where they need to understand what they are up against (and find the flags!).

Server-side Linux malware is a real threat now. Unfortunately, unlike for its Windows counterpart, most system administrators are inadequately trained or don't have enough time allocated to analyze and understand the threats that their infrastructures are facing. This tutorial aims at creating an environment where Linux professionals have the opportunity to study such threats safe and in a time-effective fashion.

In this introductory tutorial you will learn to fight real-world Linux malware that targets server environments. Attendees will have to find malicious processes and concealed backdoors in a compromised Web server.

In order to make the tutorial accessible for a range of skill levels several examples of malware will be used with increasing layers of complexity — from scripts to ELF binaries with varying degrees of obfuscation. Additionally, as is common in Capture-The-Flag information security competitions, flags will be hidden throughout the environment for attendees to find.
