Recently I noticed a lot of traffic generated by automated bots that were checking for vulnerabilities in my web server. They were mainly looking for ways to hack into plesk/wordpress which I don't even have running on the server.
Now my question is, what are hackers trying to accomplish by hacking the server. I mean, even IF they manage to hack into plesk and take over some sites for a day or two, I would still be able to hard-reset the whole server thus rendering their efforts useless again?
Why are they doing it? What's the catch?
