WASHINGTON, Nov 26 (Reuters) - Hackers are hijacking U.S. radio transmission equipment to broadcast bogus emergency messages and obscene language, the Federal Communications Commission said on Wednesday.
In a public notice, the FCC said a "recent string of cyber intrusions against various radio broadcasters" had occurred, resulting in the issuance of the U.S. Emergency Alert System's "Attention Signal." The signal is an attention-grabbing sound that is meant to precede official announcements related to tornadoes, hurricanes, earthquakes and other emergencies.
The FCC said the hackers appeared to have compromised improperly secured equipment made by the Swiss network audio company Barix and reconfigured it "to receive attacker-controlled audio in lieu of station programming."
The agency said affected stations "broadcast to the public an attacker-inserted audio stream that includes an actual or simulated Attention Signal and EAS alert tones, as well as obscene language, and other inappropriate material."
