From the "it couldn't happen to us" department:
I just received this email from my ISP.
We are no longer allowing ANY of Matt Wright's scripts to be run on any of our servers. This includes semi-private servers, as well as all other hosting accounts. These scripts have been a huge security risk and, today, some of Matt Wright's scripts severely effected several of our servers.
Today, a spammer had compromised security holes in these scripts and literally flooded our network with outgoing spam, meaning that almost all available bandwidth was being used to send spam for about 20 minutes (until we could find and shut them down).
I sent them the url for nms
