Linux Playbook
A step-by-step Linux playbook covering terminal operations, file handling, permissions, networking, scripting, OpSec, and a final capstone to apply everything in a real-world attack workflow. Learners move from terminal navigation and file handling into permissions, network inspection, shell scripting, and operational security, then apply those skills in a capstone. The module is designed for learners building practical Linux foundations for authorized security work. Exercises use a Linux shell and standard command-line utilities; the objectives describe the skills practised without giving away challenge solutions.
Tactical attack scenario
You gain shell access to an enterprise node. You must navigate the server file hierarchy, identify permission misconfigurations, locate hidden developer accounts, and escalate privileges to Root.
