A security researcher identifies vulnerabilities, flaws, and malware in software applications to improve security measures, differing from programmers and hackers in their approach and expertise. Due to increasing cyber attacks, there is a growing demand for security researchers, who act proactively to safeguard systems, sometimes employing ethical hackers for penetration testing. Ethical dilemmas exist in responsible disclosure of vulnerabilities, as researchers must balance informing stakeholders while preventing malicious exploitation.
