Abuse Desks

Centralized logging and run the analysis on the aggregate. You're more likely to catch them that way. No, it isn't guaranteed, but it's easier.

The bad guys have already gamed that system. If you have a zillion bots, you 
can have each bot try a different name/password on a large batch of IP 
Addresses. A victim only sees one try from each bot. 

The daily logwatch reports that land in my mailbox are full of ssh attempts 
that end with ": 1 Time".

"don't have the bandwidth" is an interesting term. Is that because the 
problem is really hard and it would take a lot of bandwidth/money/whatever, or 
because they choose not to spend money on it and the rest of the net is 
letting them get away with it?

Agreed. But the abuse desk is the only place where somebody can find the 
signal in the noise, and with the current pattern, much of the signal is 
trying to hide in the noise. The abuse desk will only see the signal if 
people actually send in abuse reports and the abuse desk actually looks at

I don't report phishing websites unless somebody spams me with the URL. 

These are my opinions. I hate spam.
