OverTheWire Leviathan Level 0 tutorial!!

Login

ssh leviathan0@leviathan.labs.overthewire.org -p 2223
# password: leviathan0

Each level has its own username/password. Passwords are always the solution from the previous level, but for Level 0, OTW gives it directly (leviathan0).

Task

The OTW prompt doesn’t give much here — it’s basically just the entry point. Our job: log in successfully and start exploring.

Theory

• The Leviathan wargame is about binaries and SUID programs.
• Level 0 is just a warm-up login (similar to Bandit Level 0).
• Once inside, we’ll begin recon: listing files, searching for SUID binaries, checking configs.

Solution

1. Open terminal and run:

ssh leviathan0@leviathan.labs.overthewire.org -p 2223

1. Enter the given password:

leviathan0

1. Boom 🎉 you’re inside as leviathan0.

At this point nothing else to solve — just confirm you can connect. The real fun starts at Level 0 → 1.

Password for Next Level

(You don’t need to find it here — OTW provides it: leviathan0)

That’s it for Level 0! 🎉 It’s purely a login test, but from here we’ll start digging into actual binaries.

Thanks for reading!

Until next time — Otsumachi!! 💖☄️✨
