The system used to broadcast to the United States in times of national crisis can be hacked, researchers have warned.

The Emergency Alerting System (EAS) was set up to allow the president to talk to the entire country within 10 minutes of a disaster.

Security specialists IOActive said one TV network's output "was interrupted by news of a zombie apocalypse".

Lead researcher Mike Davis said the system needed to be re-engineered.

IOActive has released a guidance sheet for concerned broadcasters looking to protect their system.
'Extremely dangerous'

In February, weaknesses in the system - which was introduced in 1997, replacing an older set-up - were exposed by hackers.

"Earlier this year we were shown an example of an intrusion on the EAS when the Montana Television Network's regular programming was interrupted by news of a zombie apocalypse," said Mr Davis.
