In the world of web application security, few names carry as much weight—or as much infamy—as SQL Injection (SQLi). Despite being first discovered over two decades ago, it remains a persistent vulnerability, consistently ranking in the OWASP Top 10. For those looking to move beyond theory and into practical exploitation, the project offers a gamified, hands-on training ground.

This payload causes the SQL query to look like WHERE username='admin\' AND password=' OR 1=1; --' . The backslash escapes the single quote after admin , effectively commenting out the password check.

The logical part ""="" always evaluates to true, effectively bypassing the password check. The query will return the row for the admin user, granting access.

Use ORDER BY to find the number of columns. 1' ORDER BY 1-- (Works) 1' ORDER BY 2-- (Works) 1' ORDER BY 3-- (Breaks? Then there are 2 columns) Identify Data Types: Test which columns display text. Extract Data: Use UNION to select database information:

SUBSTRING(..., 1, 1) : This grabs the very first character of that targeted string.

Better:

The final query processed by the SQL engine becomes:
