How cruel..
I agree with this:

“I count this in the same category of teenagers who think it’s funny to put a cat in a bag and throw it over a clothesline — they don’t realize how cruel it is,” said Paul Ferguson, a security researcher at antivirus software maker Trend Micro Inc. “It was an opportunity waiting to happen for some mean-spirited kid.”

I don’t think the hacker(s) had meant this as an actual attempt at causing people real harm, but just as a joke not thought through well enough before enacted…

Good that no one got really hurt, this could have turned out really really ugly :-/
