I've heard of hackers taking over a radio station's music library or freezing their equipment. But I can't quite recall having their on-air feed interrupted by someone with an evil intent. It happened suddenly Sunday on a Houston sports radio station.
One second KFNC was broadcasting an NFL game. The next it was spewing hate. Those in charge eventually managed to get their regular programming - the Eagles-Cowboys game - back on the air. But until then, what listeners heard was very ugly.

Perhaps equally as disturbing is that if a hacker can figure out how to do it at one place, they can do it remotely to another.
So far, no one has taken responsibility for the interruption, which apparently included the "n" word. There's also no word on how they did it. The station hurriedly moved to assure its audience it wasn't anything they were doing.

This station doesn't show up in the Houston Neilsen ratings. It is possible that the privately owned station is not a subscriber. Sports radio is not overly popular. The two formatted stations rank 23rd and 24th with shares of 1.2 and 1.1.

Every station can potentially learn a lesson from what let this happen.

If you're going to use IP feeds going into or out of a radio station, make sure the passwords are extremely complex and changed at regular intervals. I'm talking multiple combinations of letters (both caps and lowercase), numbers and lots of symbols. Also try to use uncommon usernames if possible.

Then I should write said password on a post-it note in a public spot????

Apparently, there is a specific kind of equipment that is prone to this if not properly secured.
It happened to a Virginia radio station this week, in addition to the one in Texas.
"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.”
