[ale] Network intrusion

[George Johnson]

I rather hurriedly installed a new wireless network device before I left 
for Florida as my old one had been hit by lightening.  I did not take 
time to secure it.  I just wanted it up for my roommate who does not use 
the internet much but might need it once in a while when I was gone.  
When I got back I found someone had decided to use it in the bottem 
floor apartment.  I immediatly cut him off by blocking his MAC and 
restarting the router.  I am going to Florida again for about a week or 
so and want to mess with him when I get back.  Is there any good hacking 
programs I can use to attack his system and leave nasy grams on it for 
him to see?  I would love to scare the pants off of him and make him 
wish he had never thought himself so smart as to get on my network in 
the first place.
