all the comment wars are currently going on on,,

Do we need to see them here too?

My $0.02.

No new tricks were applied. Sendmail, loadmodule, rdist, yp/nis, and
PC-based packet sniffing were all exploited to gain initial entry and obtain 
root on internet systems.

Then the compromised systems were trojaned to snoop/sniff/tcpdump logins and
passwords on the internet..

We also have seen increased ISS activity, but this may be unrelated.
(or a super-strain if iss).

Use of one-time passwords, digital tokens, or other enhanced authentication
technology, as well as decent firewalling prevents these attacks from
(plus keeping current on vendor patches)
