Which hacker type is likely to help fix security flaws?

The correct answer is White Hat Hacker. This term refers to ethical hackers who use their skills to improve security systems rather than exploit them. White Hat Hackers are often employed by organizations to perform penetration testing, vulnerability assessments, and to identify security weaknesses in systems and applications. Their goal is to safeguard against malicious attacks by addressing security flaws before they can be exploited by those with harmful intentions.

In contrast, other types of hackers, such as Black Hat Hackers, engage in illegal or unethical activities, typically seeking personal gain by exploiting security vulnerabilities. Red Hat Hackers also take an aggressive stance against Black Hat hackers, often resorting to counter-attacks rather than fixing vulnerabilities. Blue Hat Hackers, while similar to White Hats in their intent to enhance security, typically refer to individuals external to an organization who are invited to test a system for vulnerabilities, rather than being integrated into the organization's security team.

Overall, the proactive and constructive approach of a White Hat Hacker in identifying and fixing security flaws is what distinguishes them as the correct answer in this context.
