Security Training Range · Getting started

Everything you need to begin. This page costs you nothing.

⚠ No AI assistants during the exercise

This range teaches you to reason through real systems. Please do not use AI / LLM tools (ChatGPT, Claude, Copilot, Gemini, and the like) to find flags, write exploits, or decide your next move. Leaning on them defeats the whole point: you learn by doing the recon yourself, reading the errors, and making the calls. When you're genuinely stuck, use the built-in ctf-hint coach - that's what it's there for.

Getting started free hint

You have a coach on every host. It talks to this scoreboard.

`ctf-hint`	your current objective + progress
`ctf-hint --start`	start your clock — begins the timed run
`ctf-hint --hint`	reveal a tip — costs escalating points, asks first
`ctf-hint --submit 'flag{…}'`	submit a flag you found
`ctf-hint --status`	your score breakdown
`ctf-hint --scoreboard`	these standings, in your terminal

How scoring works

Solve flags for points (8 steps, 1250 total).
Each hint costs more than the last (5, 10, 15, …). Skip them when you can.
Finish faster for a bigger time bonus (up to +300, decaying to 0 over 180 min). Your clock starts when you run ctf-hint --start, so read this page, SSH in, and look around first (all free), then start it when you're ready to race.

First move

SSH into the entry host with your handle and the private key you were given (it matches the public key shown on your signed-in page above):

ssh -i /path/to/your-key your.handle@entry.ctf.amini.ai

your.handle is your corporate username prefix (e.g. alex.int for alex.int@amini.ai). Once in, run ctf-hint to see your objective and ctf-hint --start when you're ready. You're tracked automatically as your login handle - no setup needed, even after you pivot to other hosts.

Rules of engagement: everything in 10.10.0.0/16 is fair game. Nothing outside it.
