Facebook, YouTube, and Twitter remove Zelensky deepfake

The deepfake spread widely online Wednesday, as noticed earlier by Vice’s Motherboard. In the video, which CNN Business has reviewed, Zelensky appears to stand behind a presidential podium and in front of a backdrop, both of which feature the Ukranian coat of arms. Wearing a green shirt, Zelensky speaks in Ukranian, appearing to tell Ukranians to put down their weapons in the weeks-old war against Russia.

Deepfakes — which combine the terms “deep learning” and “fake” — are persuasive-looking but false video and audio files. Made using cutting-edge and relatively accessible AI technology, they aim to show a real person doing or saying something they did not. Experts have long been concerned that, as they improve, they would be used to spread misinformation.

In a series of posts on Twitter Wednesday afternoon, Meta’s head of security policy, Nathaniel Gleicher, wrote that the company spotted and removed the video earlier that day. “We’ve quickly reviewed and removed this video for violating our policy against misleading manipulated media, and notified our peers at other platforms,” he wrote.

Hany Farid, a professor at the University of California, Berkeley, and digital forensics expert, pointed out several of the obvious signs that the video is a deepfake. First, it’s a low-quality, low-resolution recording; this is a common trick to hide the distortions created when making a deepfake, as our brains tend to be more forgiving of glitches in low-quality videos. Second, the Zelensky in the video looks straight ahead without moving his arms throughout the clip — it’s very tricky to make a convincing deepfake that includes head motions and hands moving in front of the face. Third, there are little visual inconsistencies in the video, he pointed out, that occur during the process of making a deepfake, which is created a single frame at a time. Though Zelensky’s voice is harder for Farid to comment on, in part because he doesn’t speak Ukranian, he said it sounds a bit off to him.
