ALERT! Check Encoders for Emergency Alert System (EAS) Vulnerability

Certain vulnerabilities in EAS encoder/decoder devices that, if not updated to most recent software versions, could allow an actor to issue EAS alerts over the host infrastructure (TV, radio, cable network).

The vulnerability is quickly becoming public knowledge.

FEMA strongly encourages EAS participants to ensure that:

  • EAS devices and supporting systems are up to date with the most recent software versions and security patches;
  • EAS devices are protected by a firewall;
  • EAS devices and supporting systems are monitored and audit logs are regularly reviewed looking for unauthorized access.

FEMA values their partnership with broadcasters and appreciates efforts to maintain public trust and confidence in the Emergency Alert System.
