Silent calls have become a prevalent tool for scammers aiming to clone victims' voices and perpetrate fraud. Although these calls may seem innocuous at first, with just silence on the other end, they serve a malicious purpose. The quick silence allows the scammer to gather enough vocal data when the victim unwittingly speaks, subsequently training artificial intelligence software to replicate their voice with impressive accuracy. This alarming trend, referred to as evolved vishing, highlights the evolving tactics of fraudsters who adapt to new technologies.
