It could be malicious, but I imagined it's some third world wanabe hacker/researcher, who doesn't know any better, operating at the edge of his abilities.

Is that not still malicious?

Those people should be banned from using the civilized internet, their intent or at least their effect is harm - that is the important bit.

If they managed to get in, find some resource they could access, they would do it. Those people don't deserve to be on the internet.

Like someone who doesn't know how to use a gun and accidentally shoots someone to death
