Blind UNION-based SQLi with Python

Blind UNION-based SQLi with Python. See how Python can beat Burp Suite in brute-forcing speed and boost your hacking efficiency.

[Scenario]

Once, I was sharpening my skills on blind SQL injection by enumerating a vulnerable web application. I found the trivial username ‘administrator’ and his password length using conditional statements within the cookie field:

‘ UNION SELECT ‘a’ FROM users WHERE username=’administrator’ AND length(password)=20--
