A penetration tester is investigating a buffer overflow on the myfile binary. The tester wants to send a payload to help identify the exact offset to inject the memory address to take control of the buffer. Which of the following would allow the penetration tester to quickly identify the offset?
- A./myfile < $(printf βA%.0sβ {1.1000}
- Becho βAβ |head -n 1000 |tr -d β\nβ | ./myfile
- Cpython -c βprint(βAβ*1000)β > test.txt; cat test.txt >./myfile
- D./pattern_create.rb 1000 > test.txt; ./myfile < test.txt (correct answer)

The correct answer is D. Option D: ./pattern_create.rb 1000 > test.txt; ./myfile < test.txt This option decouples the components so they scale independently and absorb load spikes.
