What exactly is this rubbish?

Code:

partner.waawaa.com/Member/auto1.txt?

I saw some random guest trying to add something like this at the end of a URL on my forum, almost like some really lame and useless attempt at hacking. I'm not particularly wanting to risk seeing what the file is exactly, but is this some kind of attempt at a security breach? Nothing happened, the site's fine and the patches and mods are all up to date, and said guest has left, but what exactly is this?

Nothing I can find on Google.

 

Yep, exactly. Someone making a lame attempt at hacking you.

We saw it all the time on a forum I used to be an administrator at.

 

Thanks. Now if only I had the IP to ban.

 

How did you see that being done?

 

^Who's online. It had it as the location.

 

I dont understand whats the main reason why they want hacking. Its not good at all. Its good to know that cheat-master30 is smart and he really notice it.

 

Yep, exactly. Someone making a lame attempt at hacking you.
