“Big flaw” threatens US emergency alert system, DHS researcher warns

The US Division of Homeland Safety is warning of vulnerabilities within the nation’s emergency broadcast community that makes it potential for hackers to subject bogus warnings over radio and TV stations.

“We lately grew to become conscious of sure vulnerabilities in EAS encoder/decoder gadgets that, if not up to date to the latest software program variations, may permit an actor to subject EAS alerts over the host infrastructure (TV, radio, cable community),” the DHS’s Federal Emergency Administration Company (FEMA) warned. “This exploit was efficiently demonstrated by Ken Pyle, a safety researcher at CYBIR.com, and could also be introduced as a proof of idea on the upcoming DEFCON 2022 convention in Las Vegas, August 11-14.”

Pyle informed reporters at CNN and Bleeping Computer that the vulnerabilities reside within the Monroe Electronics R189 One-Net DASDEC EAS, an emergency alert system encoder and decoder. TV and radio stations use the gear to transmit emergency alerts. The researcher informed Bleeping Pc that “a number of vulnerabilities and points (confirmed by different researchers) have not been patched for a number of years and snowballed into an enormous flaw.”

“When requested what will be executed after profitable exploitation, Pyle stated: ‘I can simply acquire entry to the credentials, certs, gadgets, exploit the online server, ship faux alerts through crafts message, have them legitimate / pre-empting indicators at will. I also can lock legit customers out after I do, neutralizing or disabling a response,’” Bleeping Pc added.

This isn’t the primary time federal officers have warned of vulnerabilities within the emergency alert system.
