EAS Broadcasts Could Be Spoofed
by Artie Kaye
There is a possibility in the coming weeks to have false or misleading EAS messages sent out due to a vulnerability.
FEMA, the FCC, and DHS have all issued warnings in the last 2 weeks about the vulnerability in the Emergency Alert System. The flaw lies in the software of certain models of encoders and decoders which are responsible for sending the notices out over TV, cable, radio, satellite, and other communications vectors. The warnings come ahead of a hackers convention where it will be discussed by a security researcher, making its use more widely known. The agencies mentioned above strongly encourage updating software and firmware in the devices, regardless of the manufacture.
