What is the primary aim of an injection attack?

The primary aim of an injection attack is to execute malicious data in application commands. Injection attacks, such as SQL injection, command injection, and others, involve inserting or "injecting" malicious input into a program, which is then processed as part of the command executed by the application. This can allow an attacker to manipulate the behavior of the application, often leading to unauthorized access to data, the ability to alter or delete data, or execution of arbitrary commands on the server.

For example, in an SQL injection attack, an attacker might input specially crafted SQL statements that get executed by the database server in a way that exposes sensitive data or allows the attacker to manipulate the database. This kind of attack exploits vulnerabilities in the way user inputs are handled and shows how critical it is to validate and sanitize user input.

The other options do not align with the primary goal of injection attacks. Overwriting files on the server, encrypting sensitive information, or boosting application performance are not direct objectives of injection techniques, which are primarily centered on executing unintended commands or gaining control over a system by exploiting input handling flaws in applications.
