Question: In the context of buffer overflow attacks, what is a "ROP chain"?

Answer:

In the context of buffer overflow attacks, a "ROP chain" refers to a series of return-oriented programming gadgets used for building an exploit payload. These gadgets are short sequences of instructions ending with a return instruction, allowing attackers to construct a sequence of operations without injecting new code.

MCQ: In the context of buffer overflow attacks, what is a "ROP chain"?
