In my Apache logs, I'm getting a bunch of Unicode URL's showing up and I don't know why. I can't find any information on it and I'm wondering if I've been hacked or something.

Can somebody tell me what is happening please? I'm really worried about this.

Someone tried to insert shellcode. If that is a harm for you depends if you have an application that sends those code to your OS.
For some users here at apachelounge mod_security is their protection.

I tried mod_security2 and it didn't seem to do anything at all to stop this.

I got it off this site and set it up exactly like the readme. Is there some special config I need to add to get it to block this? Or at least show it as a 404 or something. The 200 code is the main thing bothering me. It makes it seem like the attacks are getting through.
