The most common type of attack happens today in the internet world towards web applications. The attack initiated by an automated process to try large number of possible values
-
Session Fixation Attack
-
Brute force attack
-
Insecure Direct Object Reference
-
Injection Flaws
To answer this question, the user needs to know about common types of attacks on web applications and their characteristics.
Option A: Session Fixation Attack, which is also known as a session hijacking attack, involves an attacker fixing the session identifier of a user to gain unauthorized access to the user's account. This option is incorrect because it does not match the given scenario.
Option B: Brute force attack is the correct answer. A brute force attack is a common type of attack where an automated process tries a large number of possible values to crack a password or find a key. This type of attack is often used to gain unauthorized access to a system or application. This option matches the given scenario.
Option C: Insecure Direct Object Reference is a type of attack where an attacker can access an unauthorized resource by manipulating an object reference. This option is incorrect because it does not match the given scenario.
Option D: Injection Flaws are a type of attack where an attacker sends malicious input to an application to exploit a vulnerability and gain unauthorized access to the system. This option is incorrect because it does not match the given scenario.
Therefore, the correct answer is:
The Answer is: B. Brute force attack.
A brute-force attack is exactly this: an automated process that systematically tries a large number of possible values (passwords, tokens, IDs, etc.) until it finds one that works. Session fixation and insecure direct object reference are specific, targeted flaws rather than exhaustive automated guessing, and injection flaws involve crafting malicious input rather than trying many values.
