One of the problems we sometimes run into checking over plugins that hackers look to be targeting is that hackers don’t always have a good understanding of what they are doing. We have seen in them trying to exploit vulnerabilities that don’t exist and trying to exploit vulnerabilities in a way that won’t ever succeed. The former issue can be caused by false or inaccurate reports of vulnerabilities released by others and the latter due to a lack of testing before trying to exploit them on other people’s websites.
