What technique is utilized in SQL injection attacks?

The correct answer pertains to exploiting server-side scripts, which is a fundamental technique in SQL injection attacks. SQL injection occurs when an attacker is able to insert or "inject" SQL code into a query that is intended to be executed by a database server. This exploitation takes advantage of vulnerabilities in the server-side scripts that construct and execute SQL queries based on user input. When the scripts do not properly validate or sanitize this input, an attacker can manipulate SQL queries to gain unauthorized access to data, modify database contents, or execute administrative operations.

By targeting server-side scripts, the attacker can bypass authentication mechanisms, retrieve sensitive information, or even delete data, all while appearing to be a legitimate user to the database system. This highlights the importance of employing proper input validation, parameterized queries, and prepared statements as protective measures against such attacks.

In contrast, the other techniques mentioned—manipulating hyperlinks, overloading network buffers, and intercepting data packets—are associated with different types of cyber attacks and do not directly relate to the mechanics of SQL injection.
