Stop The
Hacker
A free cybersecurity game where you face real attack scenarios and learn to defend yourself — built by the people who stop breaches every single day.
Phishing. Vishing. Social engineering. Ransomware. Insider threats. Can you spot them all?
What will you face?
Every scenario is based on attacks we see in the real world. What seems obvious on paper is surprisingly hard in the moment.
“You receive an email from "IT-Support@micros0ft-helpdesk.com" saying your Microsoft account will be locked in 24 hours. There's a button: "Verify Now."”
“Someone calls saying they're from your bank's fraud department. They already know your name, last 4 digits of your card, and recent transactions. They ask you to confirm your full card number to "protect your account."”
“You find a USB drive in the office parking lot labeled "Q4 Salaries — Confidential." You're curious. What do you do?”
“A colleague leaving next week asks you to share your credentials so they can finish their project over the weekend "since their access is already being revoked."”
The real game doesn't show you the correct answer first — answers are revealed after you choose, with a full explanation of why.
Who should play?
Anyone who uses a phone, a laptop, or email. So — everyone.
Why is it free?
We respond to real breaches every day. Most of them start with a single human mistake — a clicked link, a shared password, a call from someone pretending to be IT support.
Technical security controls are essential. But the more people who understand how attackers operate, the harder every attack becomes. Security education shouldn't be locked behind a corporate paywall or mandatory annual training that nobody pays attention to.
So we built Stop The Hacker and made it free — for employees, students, families, and anyone curious enough to play. The better educated the world is about cybersecurity, the safer everyone becomes.
