Sixth Movie-Plot Threat Contest

It's back, after a two-year hiatus. Terrorism is boring; cyberwar is in. Cyberwar, and its kin: cyber Pearl Harbor, cyber 9/11, cyber Armageddon. (Or make up your own: a cyber Black Plague, cyber Ragnarok, cyber comet-hits-the-earth.) This is how we get budget and power for militaries. This is how we convince people to give up their freedoms and liberties. This is how we sell-sell-sell computer security products and services. Cyberwar is hot, and it's super scary. And now, you can help!

For this year's 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.

Entries are limited to 500 words, and should be posted in the comments. In a month I'll choose some semi-finalists, and we can all vote and pick the winner.

Good luck.
