At the start of this year, a video popped up on social media sites in India showing the chief executive of the Bombay Stock Exchange, Sundararaman Ramamurthy, giving investors advice on which stocks to buy.
Viewers were promised handsome returns if they heeded his advice.
The only problem was, it was not Ramamurthy speaking. It was a deepfake video of him, made using artificial intelligence.
"It was in the public domain where many people could see it, and get cheated into buying or selling stocks, as if I'd recommended them," explains Ramamurthy.
"When we see an incident like this, we immediately lodge a complaint. We go to Instagram and other places where it's posted to get the video taken down. And we regularly write to the market warning people not to believe in fake videos."
