Havij is an automated SQL injection tool used by penetration testers to identify and exploit vulnerabilities in web applications
Once Havij extracted password hashes (usually MD5), it didn't stop there. Version 1.19 featured an integrated online hash lookup system. It could send the captured MD5 hash to online rainbow table databases (like md5crack.com) and retrieve the plaintext password automatically. Havij - Advanced SQL Injection 1.19
