Bitcoin boo-boo, deepfakes for good, and time to say goodbye to usernames?

Deepfakes are being used for good (perhaps), common usernames could pose a security threat, and someone has paid a $500,000 fee... just to send $1,865. Oh, and our guest mentions Mr Blobby (to the horror of the show's hosts...) All this and much much more is discussed in the latest edition of the "Smashing Security" podcast by cybersecurity veterans Graham Cluley and Carole Theriault, joined this week by The Cyberwire's Dave Bittner.
