This is an impromptu tutorial on tracing skiddiots - because I just found one in our logs:

I'm sure we all recoginse the cook-book directory traversal explot attempted here (which failed btw). So it's a kiddiot. Let's take a quick trip to www.samspade.org :

So the kiddiot is (probably) a student at University of Virginia. A nasty letter to the Netblock administartor will mean that's one kiddiot who's in for a nasty shock monday morning Word Up - and the word was 'busted'.

Hi --

You are listed as the admin contact for the Netblock: 199.111.0.0 - 199.111.255.255

We monitored an attempted network intrusion from an address in your IP range today (2002-06-15). The attack, (which failed) came from IP address 199.111.104.201 at 17:49:30(GMT). The actual attack attempted was a simple directory traversal expolit against a command line.

I would be grateful if you could take appropriate sanctions against the student involved. Someone obviously considers themselves to be 'l33t' - perhaps you could explain to them that under new US legislation that such exploits are classed as terrorism.

Regards,
