What is a SQL Injection Attack?

A SQL Injection Attack is a type of cyber attack where an attacker exploits vulnerabilities in a website’s database to manipulate or retrieve sensitive information.

Definition and Explanation

A SQL Injection Attack is a type of cyber attack where an attacker manipulates a website’s database by inserting malicious SQL code into input fields.

This allows them to gain unauthorized access, modify or delete data, and even take control of the website.

It is a serious security vulnerability that can have severe consequences for a website’s integrity and user privacy.

How SQL Injection Attacks Work

SQL Injection attacks occur when malicious actors manipulate input fields on a website to inject unauthorized SQL code into a website’s database.

This allows them to access, modify, or delete sensitive information stored in the database.
