Fraudsters are increasingly using deepfake videos of CEOs and other company executives to trick firms out of millions of dollars. And with the evolution of AI, these videos are becoming ever-more sophisticated and convincing.

We speak to two CEOs who have been deepfaked: the head of the Bombay stock exchange and the boss of password security company LastPass. And we hear how criminals used deepfake videos to trick British engineering firm Arup into handing over $25 million.

How easy is it to make these videos? Ed Butler visits a cybersecurity company which shows him how it can be done, using readily available software. Ed's hosts make a deepfake of him and we compare the real Ed to the fake Ed. We also put figures on the size of this problem and explain how much it's costing businesses.
