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. A spokesman for IOActive said that his group released the announcement today only after working with CERT to notify the vendors first and give them time to notify customers and work on fixes.
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. The wireless text alerts were used to warn Oklahoma residents during recent tornadoes as well as during the Boston Marathon bombing manhunt to tell residents to remain indoors. China has passed controversial new anti-terrorism laws, saying they are needed to combat growing threats.
Emergency Warning & Information Systems (EWIS) are very much a part of life these days. It is no wonder that confusion abounds when talking about EWIS systems as there are multiple standards out there that refer to or partially cover EWIS systems.
This document details the technical requirements for an emergency warning sound system including required sound pressure level, coverage and intelligibility, cabling requirements, component monitoring, error reporting, and operation under mains fail conditions.


A common theme of both documents is they specify requirements of the system as whole, not individual components. In other words, it is up to the system designer to select suitable components and design a system to comply with the (system) standards. Yes, it is true that several manufacturers offer components with features designed specifically to suit EWIS applications, but this does not constitute any form of approval and certainly does not exclude other products from these applications. Conversely; occasionally you may see manufactures who claim IEC60849 (or alternate standard) compliance on their product specification sheets. Emergency Warning Systems to improve the preparedness of, and communication with communities at high risk from natural disaster, not only bushfire related.
The considered selection of EWS components, and careful planning in design and implementation with all key stakeholders is just the beginning.
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. Unfortunately, there is no simple answer to this question as the Australian standards are not product specific, they are system standards.
Note my use of the term ?most relevant? as these standards make reference to other standards documents and to BCA documents.
The document details the IEC requirements and shows local variations applied to the Australian standard.
As long as the SYSTEM meets the standards, you are free to use whatever components you wish (in context of the sound system). You may use the existing system for EWIS announcements as long as it is engineered to comply with the standards listed above. The standards demand load monitoring; however, they do not state how this must be implemented.
These are legally binding documents and let?s face it, the ultimate purpose of these systems is to save lives, and this should never be under engineered.
Integration of these systems with Emergency Services warning and response planning is critically important, and Bushfire Risk Reducers have been recognised in their capacity for delivering operational systems, for use by the key stakeholder groups in high risk communities.


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. There is no ?EWIS approved? standard that applies to individual products (at least with respect to sound systems).
Including links to suppliers product and standards published by various organisations including, but not limited to, UL (Underwriters laboratories), ISO (International Organisation for Standardisation), IEC (International Electro technical Commission), AS (Standards Australia), and BCA (Building Code or Australia). However, AS1670.4 and AS60849 cover the majority of technical requirements specific to sound system applications. However, this is no guarantee of system compliance as it is possible to build a system entirely from ?compliant? products, yet the system could fail to meet specifications due to design or installation errors (e.g.
Yes DC monitoring is one way to do it, but any method that meets the requirements of the standard is acceptable. 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 following article attempts to explain the relevant standards and (hopefully) address some of the apparent confusion over this. I would love to be allowed to reproduce these documents as part of this article; however, the good folk at Standards Australia tend to take a dim view of this.
So if you wish to obtain a copy of these documents you will need to purchase them from Standards Australia.
Please don?t email me complaining about these prices, for what it?s worth, I agree, but I don?t want to start a Standards Australia rant in this issue.
