In order to be able to follow up on the latest security warnings, we often spend time on vulnerability rewards and ctf competitions. When we discuss what we want to do this weekend, Matthias comes up with an interesting idea: What goals can we use to attack ourselves? The answer is Google search engine. For scanning google vulnerabilities, what can be better than google search engines. What is the most likely breakthrough? ① Old and unmaintained software ② unknown and difficult software ③ only a
