South Korean journalist Ko Narin had published what would turn into the biggest scoop of her career. It had recently emerged that police were investigating deepfake porn rings at two of the county’s major universities, and Ms Ko was convinced there must be more.

She started searching social media and uncovered dozens of chat groups on the messaging app Telegram where users were sharing photos of women they knew and using AI software to convert them into fake pornographic images within seconds.

“Every minute people were uploading photos of girls they knew and asking them to be turned into deepfakes,” Ms Ko told us.

Ms Ko discovered these groups were not just targeting university students. There were rooms dedicated to specific high schools and even middle schools. If a lot of content was created using images of a particular student, she might even be given her own room. Broadly labelled “humiliation rooms” or “friend of friend rooms”, they often come with strict entry terms.
