Unix viruses....

I probably should not be writing this, but if you look at
the book "The Cuckoo's Egg" by Clifford Stoll he tells of
the first large scale Unix network meltdown in the early
days of the web.

There is a editor on Unix called Emacs that has a "shell"
mode, that if incorrectly used can be used to attain
superuser permission. The virus written would use Emacs
to attain superuser permission, and then to use the local
.rhosts file to copy itself to other machines on the network
so that it can propagate itself.

For practical reasons, writing viruses on Unix are far more
difficult than to do on Windows machines and not as much
fun.
