An anonymous reader quotes a report from Bleeping Computer: An unknown hacker has hijacked the radio frequency of a UK radio station to play an obscene song eight times during the past month, according to the radio station's manager who recently revealed the hacks in an interview with BBC Radio 4. The hacks have been reported to Ofcom, the UK's communications regulator, who together with the radio station's staff have tried to track down the culprit at last three times, without success. Ofcom and radio station officials believe the hacker is using a mobile radio transmitter to broadcast a stronger signal on the radio station's normal frequency, overriding its normal program. In eight different occasions, the hacker has taken over broadcasts and has been heard talking, screaming, or singing, and then playing "The Winker's Song" (NSFW) by British comedian Ivor Biggun, a track about self-pleasure released in the 70s. Station manager Tony Delahunty told BBC Radio he received phone calls from distressed listeners complaining that their kids started humming the song. Fellow radio stations also called Delahunty to inquire about the hack, fearing similar hijacks.
