Each of the major viruses has probably got one author singular.

There are ways of making systems much more resistant to attack including
viruses. Things like RSBAC and the NSA security modules help you get
into a situation where this kind of stuff doesn't occur

User1 gets a virus
User1 owns a binary root users
Root gets the virus
Splat

Because with a trust model it goes instead

User1 geta a virus
User1 owns a binary root users
User1 virus patches the binary

Root is refused permission to run the binary because it no longer has
a high enough integrity

Even before that the lack of people checking GPG keys on RPM and other
packages is disturbing.
