Re: Positive response from provider re: incident report

During this last summer, one of my NT machines was used for warez loading
(nearly 2GB of storage)

I tracked down about 40 users and reported them to their ISPs.  In almost
all cases I received the same type of notice that accounts had been closed.

Report scans and intrusions.  Lots of people like us do care about these
things.

Some may be asking what the problem was with my NT box....... incorrect
permission on the FTP server from the builder with write left on for
anonymous.  I should have checked it, darn.

After closing the hole, the attempts were fast and furious, so I denied FTP
at the router.... and just dropped the packets right there.

It's nice to occasionally get a response like the one below.  After five
months, I'm surprised they even bothered to get back to me.  Let's hope
this teaches them a lesson and they never do it again...yeah, right ;-)
