I havent looked at the script itself, but the basic idea is similar. Fair
enough its for one ip but in my experience the chance of the same host
scanning me twice in the same day is rare (if not never happened), also I
have taken a look at a few logs of systems I have online 24/7 and are
noticing an alarming rate of around 1500+ UNIQUE ips connecting to me in a
day and wouldnt be surprize if someone out there found more. Nimda can get
scary because it can infect entire LANs and not a nice thing when said LAN
has about 30 machines for example. And no comment on the "certain company"
who doesnt write secure software, thats best left unsaid.:)
