Which testing technique sends a large amount of data to a target to provoke a buffer overflow and identify the EIP location?

Which testing technique sends a large amount of data to a target to provoke a buffer overflow and identify the EIP location?

• A. Incident Management
• B. Threat Modeling
• C. Risk
• D. Fuzzing

Answer: (D)

Fuzzing is the practice of automatically generating and sending a large volume of varied inputs to a software program to provoke errors such as buffer overflows. By bombarding the target with oversized, malformed, or unexpected data, fuzzing aims to trigger memory corruption and crashes, which helps reveal how the program handles input and where the fault occurs. When a buffer overflow happens, analysts look at the crash to determine the offset that overwrites the return address, i.e., where the instruction pointer (EIP) ends up. Knowing this offset is crucial for understanding potential control-flow vulnerabilities and how an attacker might redirect execution. The other options focus on management or design aspects of security rather than actively uncovering input-driven vulnerabilities in software.
