🧠 Process Tree Tangle: Can You Kill the Right PID?

Ever wondered what really happens when you run kill -9 on a Linux process? In Process Tree Tangle, your job is to trace the Linux process tree and target a rogue process — without bringing down the rest of the system.

Each node in the tree represents a Linux process, complete with process ID (PID) and parent/child relationships. Some processes are critical (like init, sshd, and apache2), while others aren’t. One of them is secretly a rogue cryptominer consuming resources — can you find it and terminate it safely?

🔍 How It Works

Explore the rendered process tree
Click on a node to “kill” that process and its children
Lose points for killing critical processes unnecessarily
Gain points for smart targeting

This tool is built to help sysadmins, developers, and aspiring SREs better understand relationships between Linux processes, and the real-world risks of misfiring a kill command.
