@todayshow: TODAY's Al Roker got a message from a friend with a link to a video of himself promoting a solution to hypertension, or high blood pressure. The problem is that Al doesn't have hypertension — and the video was fake. Al's image was used in a deepfake, or a video that uses artificial intelligence to doctor video and audio that appears to be real. Scammers use these deepfakes to deceive people into giving up their money. Go to the link in bio to watch the full video and learn what you can do to stay safe from deepfake scams.
