このゲームについて

Every hacker starts somewhere. Usually, it's a blinking cursor and a bad idea.

H3LL0 H4CK3R throws you in with nothing but a terminal and your wits (and a hint system for those that need it). No hand-holding. No tutorials written by people who've never seen a command line. Just you, the machine, and a network that's begging to be compromised.

Crack systems. Cover your tracks. Build your legend—or get traced and burned.

This isn't a game about hacking. This is hacking.

What To Expect

WARNING! - HELLO HACKER will challenge you to be curious and to read and pay attention to everything. You never know what will be a clue that you need later. You will experience a realistic Linux terminal, with real commands. Careful, you may learn something. If you are interested in Linux, cybersecurity or CTF's like TryHackMe, then this game is for you. Use hints when you get stuck, but be careful... they may cost you with your place on the global leaderboard.

The Mission

Alex Chen, a security researcher and your friend, is missing. Before going missing, Alex

left you an encrypted system with one final message: "Find the breadcrumbs. Expose the truth."

Now it's your turn to finish what Alex started - but be warned: once you discover the truth, you become the next

target.
