The quality is certainly not great. Even under the guise of a bad phone signal, you can hear that the voice is a little robotic. But it's bearable.

The attack was ultimately unsuccessfulbecause the employee who received the voicemail immediately thought it was suspicious and sent it to the firm's legal department. But such attacks will become more common as deep fake tools become more available.
Everything you need to create a voice clone,Is access to many of your target's records. The more data you have and the better the sound quality, the better the resulting voice clone will be. And for many CEOs of large firms, such tapes can be easily compiled from phone calls, interviews, and public speeches. With enough time and data, the highest quality audio will be much more convincing than the example above. It is obvious that telephone scammers have reached a new level and the quality of fraud will only grow.
Earlier this year, the FTC warned of an increase in suchscammers, but experts say there is one easy way to beat them. As Patrick Trainor of the College of Engineering told The Verge in January. Herbert Wertheim, all you have to do is hang up and call the person back.
Hang up and call back. If it's not a very, very sophisticated hacker group, this is most likely the best way to find out if you were talking to whoever you thought you were.
