I very important class of attackers are those that might be powerful but
wants to stay undetected and do selective interference.

This could be to provide time for a worm to spread, or to collect
intelligence, to subvert a specific target, or to suppress security alerts

Such an attacker might look a lot like a man-on-the-side, but could
selectively rewrite packets, e.g. changing source or target IP address.
