Welcome to CMD+CTRLLearn to see web applications from an attacker's perspective. CMD+CTRL is an immersive hacking experience designed to teach the fundamentals of web application security. Explore vulnerable web applications, discover security flaws, and exploit those flaws to earn points and climb up the leaderboard. After attacking an application for yourself, you'll have a better understanding of the vulnerabilities that put real applications at risk - and you'll be better prepared to find and fix those vulnerabilities in your own code.
