This is so wrong, but also so funny.

Was this a viral marketing effort from the producers of The Walking Dead? No, it seems as though some industrious hackers breached the station’s emergency alert system, and sent out the bogus warning about zombies attacking the living.
“Someone apparently hacked into the Emergency Alert System and announced on KRTV and the CW that there was an emergency in several Montana counties,” the station said in a Monday statement. “This message did not originate from KRTV, and there is no emergency. Our engineers are investigating to determine what happened and if it affected other media outlets.”
The message kicked off like any other emergency alert – with the dialup-esque bleeps and tones and an alert crawl atop the screen. But rather than warning about a weather emergency or some other plausible situation, a menacing voice came on to warn people about zombies.
Whoever did this obviously has some braaaaains.
