SQL injection is a type of cyber attack that targets the security vulnerabilities in web applications that use SQL databases. In this type of attack, the attacker attempts to inject malicious code into a SQL statement that the web application uses to communicate with its database.

The goal of an SQL injection attack is to manipulate the SQL query in a way that allows the attacker to access sensitive data stored in the database or to perform unauthorized actions, such as deleting or modifying data. The attacker can achieve this by exploiting poorly written code in the web application that fails to validate or sanitize user input before passing it on to the database.

SQL injection attacks can have serious consequences, including data theft, loss of confidentiality, and damage to the reputation of the affected organization. To protect against SQL injection attacks, developers need to ensure that their code properly sanitizes user input and uses prepared statements or parameterized queries to communicate with the database. Additionally, regular security testing and vulnerability assessments can help identify and mitigate any vulnerabilities that may exist in the application.
