Sixth Annual Movie-Plot Threat Contest Semifinalists

On April 1, I announced the Sixth Annual Movie Plot Threat Contest:

I want a cyberwar movie-plot threat. (For those who don't know, a movie-plot threat is a scare story that would make a great movie plot, but is much too specific to build security policy around.) Not the Chinese attacking our power grid or shutting off 911 emergency services -- people are already scaring our legislators with that sort of stuff. I want something good, something no one has thought of before.

Submissions are in, and -- apologies that this is a month late, but I completely forgot about it -- here are the semifinalists.

1. Crashing satellites, by Chris Battey.
2. Attacking Dutch dams, by Russell Thomas.
3. Attacking a drug dispensing system, by Dave.
4. Attacking cars through their diagnostic ports, by RSaunders.
5. Embedded kill switches in chips, by Shogun.

Cast your vote by number; voting closes at the end of the month.
