Which statement best describes the primary purpose of fuzz testing tools like beSTORM in ethical hacking?

• A. To enumerate open ports on a target
• B. To map the network topology
• C. To test user authentication mechanisms
• D. To discover buffer overflow vulnerabilities by sending malformed inputs

Answer: (D)

Fuzz testing focuses on input handling robustness by sending malformed inputs to software to trigger abnormal behavior. Tools like beSTORM automate generating varied, boundary-case inputs and feeding them to targets, then monitoring for crashes, hangs, or unexpected responses. The aim is to reveal weaknesses in input validation and memory management that could lead to vulnerabilities like buffer overflows. This approach specifically targets how the program processes unexpected data, rather than merely discovering open ports, mapping networks, or testing authentication mechanisms.
