Lesson 3 · Try it

Log in as admin without the password.

The app pastes your username straight into its query. End the string early and the rest of your input becomes SQL.

SELECT * FROM users
WHERE name = ' ' AND password = '••••••'

Hint: the quote is the key.

Why it works

Built for the way security is actually learned.

No lecture videos. You poke the system, watch it break, then do it for real in a lab.

Every concept is something you run

Queries, packets and tickets react to your input, line by line.

-- your input becomes part of the query

SELECT * FROM orders WHERE ref = 'A12' OR '1'='1'

rows 1 284 returned (expected 1)

✓ You found the injection point.

One skill map

Courses, labs and roles all feed the same graph of what you can do.

Proof, not participation

Every skill is backed by what you actually did in a lesson or a lab, so a hiring manager can check it.

Short enough for a coffee, deep enough to remember. Review comes back right before you forget.

Every skill ends in a real lab.

When the lesson ends, the free Cyber CTF launcher starts a vulnerable environment on your machine, your own server or your cloud account. You attack it for real and submit the evidence a client would ask for.
