Which attack method involves trial and error to gain access to information?

The method that involves trial and error to gain access to information is a brute force attack. In this type of attack, the attacker systematically attempts various combinations of passwords or encryption keys until the correct one is found. This method can be incredibly time-consuming and resource-intensive, especially against a strong password or encryption. However, it is straightforward in its approach, as it relies solely on the principle of trying every possible option until successful. This is why it is classified as a trial and error technique.

Phishing involves deceiving individuals into providing sensitive information, such as usernames and passwords, by pretending to be a trustworthy entity. Denial of Service attacks aim to overwhelm a system, making it unavailable to users, rather than attempting to gain access to information. SQL injection targets databases by inserting malicious SQL code into queries, manipulating how the database processes user input, rather than using trial and error. Each of these methods has distinct objectives and techniques that differentiate them from brute force attacks.
