What happened

A deepfake video was created using AI that depicted Hungarian toxicologist Zacher Gábor dying in an explosion, with his face and name used to create the synthetic content. The video imitated a real television news report from ATV Híradó, showing an exploded and burned car while suggesting premeditated murder and conspiracy in the background.

The three-minute video was created with malicious intent to sell fraudulent products, part of a pattern of abuse of Zacher's name to market fake remedies.

Reported impact

Zacher stated that the video deceived people into thinking a secret miracle cure was so effective that pharmaceutical companies would kill to suppress it. He reported that colleagues called him concerned about the video, and that seeing such content while unable to answer calls was deeply disturbing.

Zacher described the situation as reaching a serious level, noting that while advertisements falsely attributing product endorsements to him were one concern, videos depicting his death crossed into a different and more harmful territory.

Index analysis

Zacher acknowledged that AI technology contains genius but is extremely dangerous. He noted that such cases typically close within six days because authorities cannot find the perpetrators.

This incident exemplifies how deepfake technology can be weaponized to create fraudulent video content that exploits a known public figure's identity for financial scams.

Governance controls

Zacher filed a criminal complaint with police regarding the deepfake video. He stated that he had previously filed similar complaints in other cases, which were typically closed after six weeks due to failure to identify perpetrators.
