Its not really a scam, but more of a rumor. Theres really nothing a scammer can do with a recording of the word 'yes' that couldn't be done by one of them simply immitating it themselves and recording it. My personal belief is scammers created the rumor to cause confusion and try attempting some scam (yet unknown) by getting someone to focus on not saying 'yes' during a scam call.
When I answered, I was asked "Can you hear me?" I remembered hearing on the news about this scam. I answered, "who is this?" and he repeated, "Can you hear me?" So I hung up, blocked thus number in my phone and now I am reporting it. Beware!
