SQL injection

This is a tactic that uses code injection to attack applications that are data-driven. The maliciously injected SQL code can perform several actions, including dumping all the data in a database in a location controlled by the attacker. Through this attack, malicious hackers can spoof identities, modify data or tamper with it, disclose confidential data, delete and destroy the data or make it unavailable. They can also take control of the database completely.
