1. SQL Injection
This method is the most used by hackers and among the easiest ways to deface or hack a website. SQL injection is used to get the user account and remove information from his database. This attack aims at user information using lines of code of SQL (Structured Query List) which is a database programming language. Hackers don’t have to learn the language at all because there is a software called “Havij” available on hackers’ forums that is developed in Iran and is free of cost.
It is used to exploit the database behind the website, application or a system and it’s very easy to use.
