Which type of attack does this describe?

A brute-force attack involves systematically trying all possible combinations of passwords or encryption keys until the correct one is found. It relies on computational power rather than human interaction, making it fundamentally different from social engineering, which specifically targets human vulnerabilities for information extraction.

While phishing attacks do involve tricking individuals into providing sensitive information, they are typically executed through deceptive emails or websites designed to appear legitimate. This method is a form of social engineering but is more specific in its approach. The term "social engineering" encompasses a broader range of tactics, including direct manipulation and face-to-face interactions.

An SQL injection attack targets databases by inserting malicious SQL statements into an entry field, allowing attackers to manipulate or access data without proper authorization. This method is a technical hacking technique that does not involve the direct manipulation of individuals, which is a hallmark of social engineering.
