I have had a website up for less than a month and it is not registered with any search engine. However, other than some friends who have been on it, I have seen many other IPs requesting files that do not exits on the server. On closer inspection, it appeared to be an attempt to hack my webserver. The strings in the log would look something like this:

GET /scripts/winnt/cmd.exe?/c+dir

Now, it looks to me like someone trying to access my C Drive. Is it? Or am I just being paranoid? If it isn't, then why are these people trying to request files that don't exist on a site they couldn't possibly have heard of? Are they just running some program that cycles through IP ranges and pings each one?
