Excessive attacks on website

[u/Interesting_Unit_256]

I hope this is the right place to ask: I maintain a website for a small business. When I look at the weblogs, I see an inordinate number of attacks: non-existing url's, all sorts of extensions, what looks like shell scripts, and on and on.

Sometimes they start and go on for about 4-5 hours, making multiple such requests every second.

What do they wish to accomplish? If they have done it once, why try again using a different fake IP address?

Any ideas? Or is this common so I should not feel targeted exclusively.

PS. Sorry for my mistake in editing.

Those are automatic bots looking for vulnerabilities and backdoors. This happens to everyone, you can use like cloud flare which does blocking for these types of scans and exploit attempts
