To answer this question, you need to understand the NOP sled technique and its purpose.
The NOP sled technique is a popular technique used in buffer overflow attacks.
A buffer overflow attack occurs when a program or system tries to store more data in a buffer than it was designed to hold. This can lead to the overwriting of adjacent memory locations, allowing an attacker to execute arbitrary code or take control of the system.
In a buffer overflow attack, the attacker injects malicious code into a buffer, and then overwrites the return address of a function with the address of the injected code. However, it can be challenging to precisely locate the injected code's address, especially if the buffer's size is not known.
This is where the NOP sled technique comes into play. NOP stands for "no operation," which is a type of instruction that does nothing when executed. The NOP sled is a long sequence of NOP instructions placed before the injected code. When the buffer overflow occurs, the execution flow will slide down the NOP sled until it reaches the injected code. This technique increases the chances of hitting the injected code's address, even if the exact location is not known.
Therefore, the correct answer is B) Buffer Overflow Attack Technique, as the NOP sled technique is commonly used in buffer overflow attacks.
