I'm setting up my first website on Ubuntu 18.04 using Apache and I've noticed the following in my apache error log on a daily basis:

94.102.49.125 - - [07/Feb/2019:11:32:55 +0000] "GET /muieblackcat HTTP/1.1" 301 555 "-" "-"

After some research, like ip location and reading fora/blogs, it's clear that these are attacks aimed at identifying any vulnerabilities on my server.

Being new to this, and seeing a lot of pings from the same IPs I thought I'd just add a deny rule to my .htaccess file for each IP. After two days, this clearly isn't a feasible solution.

So I'm looking for other things to do. I've noticed that most of these requests are looking for specific php files, which I fortunately don't have in the requested location.

Consequently, I'm wondering if it is possible to define a rule somewhere that says something like:

"If IP(x) makes a request for ^*.php, Deny/Block IP permanently."

If this possible, where do I define such a rule and in what language etc.

Much thanks in advance!

    Why not just use fail2ban? – Michael Hampton Feb 7 at 13:39
  • yea, I'm reading through it right now. It sounds like it'll do what i need, but how can I be sure that it won't block me or another user? – Jed Feb 7 at 13:41
