A Russia-aligned influence operation known as Operation Overload—also tracked as Matryoshka and Storm-1679—has used fake news sites, bogus fact-checking resources, AI-generated audio, and impersonation of trusted media brands to shape narratives around the US presidential election. Researchers said the campaign has heavily targeted journalists, fact-checkers, and researchers with deceptive verification requests designed to draw false claims into mainstream reporting, while coordinated inauthentic social media activity amplified the same narratives directly to the public.
The operation has sought to undermine trust in the election process, inflame fears of political violence, and exploit polarizing issues to deepen social divisions. Reported themes included fabricated scandal narratives aimed at Vice President Kamala Harris, attacks portraying Ukrainians and the LGBTQIA+ community negatively, and messaging intended to weaken support for Ukraine; the campaign had also previously attempted similar interference around the French elections and the Paris Olympics and was expected to intensify as the US vote approached.

Operation Overload, also known as Matryoshka and Storm-1679, is described as targeting the 2024 US election through fake news sites, false fact-checking resources, AI-generated audio, and impersonation of trusted media brands. The campaign heavily targets media outlets, fact-checkers, and researchers with deceptive verification requests while also spreading false narratives on social media.
The influence operation previously attempted to affect the 2024 French elections and the Paris Olympics, though the source says those efforts had limited success. This establishes earlier activity before its focus on the US presidential election.
