Some Emergency Alert System decoders vulnerable to hacking

Some key parts of the Emergency Alert System are vulnerable to hacking, according to a report from security research firm IOActive. The EAS, which replaced the old Emergency Broadcast System and can now be utilized to send alerts to phones as well as television stations, uses direct digital and analog communication that involves local application servers called decoders. At least two of these, the DASDEC-I and the DASDEC-II, are reportedly vulnerable because the manufacturer made firmware images that included a "root privileged SSH key" publicly available. That's enough for hackers to gain total access to these decoders and then shut them down or send out fake emergency messages.
