Have aliens hijacked Voyager 2 spacecraft?

wilwheaton:

I sure hope this is true, and not some kind of malfunction:

It left Earth 33 years ago, now it’s claimed the Voyager 2 spacecraft may have been hijacked by aliens after sending back data messages NASA scientists can’t decode.
NASA installed a 12-inch disk containing music and greetings in 55 languages in case intelligent extraterrestrial life ever found it.
But now the spacecraft is sending back what sounds like an answer: Signals in an unknown data format!
