Lesson 10 of 12 · Obligations and real cases

Real case: cryptocurrency mining on an exposed server

55 min Debian 12

Objective

Run the full investigation of the Web's most common incident: a server whose CPU is stuck at 100% because a cryptocurrency miner has settled in. You find the process, its connection, its persistence and above all how it got in, then clean up properly.

A typical public incident, rewritten for MasterLinux. Any resemblance of names, IPs or wallets is fictitious; the lab artifacts are simulated and harmless.
