Security Breach ?

Alright well not it's certain I have a friend on my system.  I have  
found this file named "https" on my
system in /tmp

I'm not as PERL savy as I want to be but it does open IRC on the  
server.  The file is owned by apache:apache.  So it
looks like my friend is using Apache as a tool.  Would anybody have a  
clue on how he could get this in tmp and then run it?
The file was not set executable either.
