The zombie apocalypse hasn't happened yet, but a few thousand people in Great Falls, Mont., are to be forgiven if they thought it was.

On Monday, the emergency alert system at KRTV-TV in Great Falls was hacked during the "The Steve Wilkos Show" to send out a message that "dead bodies are rising from their graves" in several counties.

The warning also told those watching not to try and apprehend the dangerous individuals, only to get to shelter and stay safe, Gizmodo.au reported.

Just in case you didn't know, there wasn't actually a zombie outbreak.

Nevertheless, KRTV-TV felt obliged to let viewers know both on the air and online that the earlier report of zombies rising out of their graves was not accurate.

"This message did not originate from KRTV, and there is no emergency," the station explained. "Our engineers are investigating to determine what happened and if it affected other media outlets."

So far, no one has been able to figure out who did the hacking or if it was some kind of viral marketing for the AMC series, "The Walking Dead," Gawker reported.
