Welcome to Cronpocalypse, an engaging and beginner-friendly Capture the Flag (CTF) challenge designed to test your Linux privilege escalation and exploitation skills. In this lab, you will navigate through a series of tasks and vulnerabilities, that might be around cron jobs, uncovering clues and leveraging your knowledge to capture two flags:

  • User Flag: flag-user.txt

  • Root Flag: flag-root.txt

Your mission is to investigate the system, identify misconfigurations or weaknesses in scheduled tasks, and exploit them to gain higher privileges. Whether you're new to CTF challenges or sharpening your skills, Cronpocalypse offers a fun and educational experience in a controlled environment.

Can you uncover the secrets hidden within this Linux machine and claim victory? Dive in and prove your mettle!
