What is SQL Injection?
SQL Injection is where hackers exploit certain software vulnerabilities in web applications for the purpose of stealing, deleting, or modifying data.
As ranked by cyber security experts, SQL Injection is seen as one of the least sophisticated and easy-to-defend against attacks.
SQL (Structured Query Language) is an age-old programming code developed back in the early 70’s. As it is quite dated, its very easy to detect, and in a nutshell, an SQL injection is where hackers enter malicious commands into web-based forms of an unsecured website and gain unauthorised access to personal data.

Types of SQL Injection
Union-based SQLi
Union-based SQL Injection is a technique that utilises the UNION SQL operator to combine the results of two or more SELECT statements into a single result, which is then returned as part of the HTTP response.
Error-based SQLi
Error-based SQLi is a technique that relies on error messages used by a database server to obtain information. An error-based SQL injection on its own may be enough for a hacker to enumerate a database.
Blind
Blind SQLi is a type attack that asks the database true or false questions and determines the answer based on the application’s response. This attack is most commonly used when the web app is configured to show generic error messages but has not mitigated the code that is vulnerable to SQLi.
