In mid-September 2026, researchers identified a Russian disinformation campaign utilizing deepfake technology to target the upcoming US midterm elections. The operation featured a series of fabricated videos depicting well-known Hollywood actors making inflammatory statements against the Democratic Party, all while using unauthorized CNN branding to lend the content a veneer of legitimacy.
What happened
The campaign, attributed by researchers to a Kremlin-linked collective known as Matryoshka or Operation Overload, utilized stolen footage and personalized videos purchased from the platform Cameo. The perpetrators layered fabricated audio onto existing recordings to make celebrities appear to make extreme political claims. Affected individuals included Alyson Hannigan, Emma Caulfield, Sarah Jessica Parker, Julia Roberts, Ed Begley Jr., and Eric Roberts.
In one instance, a deepfake of Alyson Hannigan claimed children were under threat from Democrats, while another video portrayed Emma Caulfield making violent accusations. Sarah Jessica Parker was depicted using antisemitic slurs against Ukrainian President Volodymyr Zelensky and Democrats. The operation also targeted specific political candidates, including Senator Jon Ossoff and Texas Senate hopeful James Talarico, through fake CNN-branded reports.
Experts noted that the campaign employed low-effort tactics consistent with previous Russian influence operations, including the use of inorganic bot activity to amplify the content across social media platforms. Platforms such as X, Bluesky, and TikTok have removed some of the posts, but researchers warn that this represents the initial phase of a broader effort to influence the US elections. The actors involved in the videos have publicly denounced the content, with Emma Caulfield and Ed Begley Jr. expressing feelings of violation and clarifying that the statements do not represent their personal beliefs. A CNN spokesperson confirmed that the videos were unauthorized and had no affiliation with the network.
