But a new security advisory warning warns that the EAS system is wide open to remote attacks by hackers, who can broadcast fake reports and materials. The key allows anyone with limited knowledge to log in at the root level of the server and "manipulate any system function," including browse key directories and access its peering arrangement. From the advisory, an attacker who gains control of one or more DASDEC systems "can disrupt these stations' ability to transmit and could disseminate false emergency information over a large geographic area," which in some cases could be "forwarded to and mirrored" by other systems, spreading false information over a wider area. In the event of an emergency (especially a nuclear one) TV and FM radio would stop broadcasting.
The Emergency Alert System is a national public warning system that requires TV and radio broadcasters, cable television systems, wireless cable systems, satellite digital audio radio service providers, direct broadcast satellite service providers and wireline video service providers to offer to the President the communications capability to address the American public during a national emergency. The FCC works with the Federal Emergency Management Agency and the National Oceanic and Atmospheric Administration's National Weather Serviceto implement the EAS at the national level. Radio stations and networks could break into their regularly scheduled programming in case of an emergency before 1951. Yes, it seems the system was inadvertently activated by a teletype operator who accidentally "played the wrong tape" during a test of the system. A state emergency manager can use the EAS to broadcast a warning from one or more major radio stations in a particular state. State or local authorities, the National Weather Service, or even the broadcaster also have access to this system for lesser emergencies.
EAS equipment in other radio and television stations, as well as in cable television systems in that state, can automatically monitor and rebroadcast the warning.
Thankfully, though we came pretty close, the development of these systems proved unnecessary for their intended use. CONELRAD, its successor the Emergency Broadcast System, and the current Emergency Alert System are all designed as a way for the president to quickly address the public in the event of a catastrophe like a nuclear attack or imminent meteor strike. For the most part, activation of the Emergency Alert System is automated, with alerts broadcasting from a central source (like the National Weather Service) and quickly filtering through different points until it reaches your ear holes as the blood-curdling, demonic scream of a far away computer program. Those awful screeches you hear at the beginning of the Emergency Alert System are digitized codes that communicate the type of threat, area (counties) threatened, and how long the threat is in place.
Several models of Emergency Alert System decoders, used to break into TV and radio broadcasts to announce public safety warnings, have vulnerabilities that would allow hackers to hijack them and deliver fake messages to the public, according to an announcement by a security firm on Monday.

The vulnerabilities included a private root SSH key that was distributed in publicly available firmware images that would have allowed an attacker with SSH access to a device to log in with root privileges and issue fake alerts or disable the system. IOActive principal research scientist Mike Davis uncovered the vulnerabilities in the application servers of two digital alerting systems known as DASDEC-I and DASDEC-II.
Davis indicated that to resolve the issue would require “re-engineering” of the digital alerting system side as well as firmware updates pushed out to appliances in the field. These included default administrative passwords that customers were forgetting to change after installing the systems. Earlier this year hackers used default credentials to break into the Emergency Alert System at local TV station KRTV in Montana to interrupt programming with an alert about a zombie apocalypse. During an afternoon broadcast of the Steve Wilkos talk show, a loud buzzer sounded and a banner ran across the top of the screen as an announcer’s voice warned viewers that the zombie apocalypse was upon them.
EAS is a descendant of the Emergency Broadcast System established in the 1960s during President John F.
Last year, the Federal Emergency Management Agency also launched a wireless alert system that delivers text alerts to mobile phones that are compatible with the wireless alert system. It is a nightmare glacier, tormented by the giant of our Solar System ever looming on its horizon. Emergency Alert System (EAS), which interrupts television and radio broadcasts in times of local and national warnings. The whole system works off a series of digital decoders and encoders, which the FCC oversees. The EAS allows participating providers to send and receive emergency information quickly and automatically, even if their facilities are unattended.
EAS equipment also provides a method for automatic interruption of regular programming, and in certain instances is able to relay emergency messages in languages other than English. The NWS uses the EAS on a local and statewide basis to provide the public with alerts and warnings regarding dangerous weather and other emergency conditions. Among the many ways the country prepared for the possibility of getting wiped out in some radioactive hellscape involved an intricate network of warning systems that spanned from coast to coast, quickly alerting residents to seek shelter and brace for impact. Government would order all radio and television stations to immediately stop broadcasting, and select sources would begin transmitting emergency messages over 640 AM or 1240 AM.

Back in 1971, NORAD tried to test the Emergency Broadcast System but accidentally transmitted the wrong message, leading some stations to go through the motions as if there were a real national emergency. They’re delivered to phones with a distinctively jarring tone and vibration to distinguish them from regular text messages and advise recipients to tune in to their local radio and television to get more information. During an emergency such as the recent fire in San Juan Bautista that destroyed one house and caused property damage to others, San Benito County residents do not have the ability to broadcast emergency alerts - in either English or Spanish - to a broad spectrum of community members. Along with its capability of providing an emergency message to the entire nation simultaneously, the EAS allows authorized state and local authorities to quickly distribute important local emergency information. There are more than 80 different categories of emergency warnings, including your standard tornado warnings but also things like the AMBER Alert System for child abduction emergencies. The codeword "hatefulness" was sent through the entire system, ordering stations to cease regular programming and broadcast the alert of a national emergency.
The FCC's goal is to make the EAS capable of distributing emergency information as quickly as possible to as many people as possible.
Other than that, the federal government conducted a nationwide test of the Emergency Alert System in November 2011 to see whether or not an activation on the national level would actually work in an emergency. It’s used to alert the public about weather emergencies, disasters and Amber alerts and is also available to the President of the United States to break into programming to announce a national crisis. Additionally, EAS equipment can directly monitor the NWS for local weather and other emergency alerts, which local broadcast stations, cable systems, and other EAS participants can then rebroadcast, providing an almost immediate relay of local emergency messages to the public.
If an earthquake, flood, act of terrorism threatens San Benito County, there is no mass media communication tool with which to warn and advise the public how to respond to such threats, access emergency supplies or seek police, fire department or public health advisements for safe potable water supplies. Initially, the system was designed so that alerts passed from station to station via the wire services of the Associated Press and United Press International, but it now transmits through analog and digital systems. The system also may be used by state and local authorities to deliver important emergency information such as AMBER (missing children) alerts and emergency weather information targeted to a specific area.
If one link in the system for spreading emergency alert information is broken, members of the public have multiple alternate sources of warning.
