Yup, as has been suspected, this is utter BS. First, it says he only disconnected the initially infected systems from his network *after* it had already apparently infected others. And then the article states that he continued to transfer files (and the infection) using memory sticks. And if the virus could survive system wipes, then why would he assume it was being re-spread through the speakers as opposed to simply resurfacing from the initial infection?
And spreading through the speakers? Come on. Unless there's something already on the receiving end continually monitoring the speakers to receive, compile and run the code, it's nonsense.
