Nearly all "deepfake" videos in circulation on the Internet are porn, and around a quarter of the performers whose faces have been superimposed are female Korean stars, according to a study.

There have been fears that the digital technology could be used to further fiendish political plots, but the findings confirm that man is by and large a simpler animal.

Dutch cybersecurity company Deeptrace analyzed images on five major websites distributing deepfake videos and found that a quarter of the victims were female Korean celebrities. They were only outnumbered by American and British actresses with 41 percent.
