Fact-checker Talita Burbulhan discovered a TikTok video claiming that Brazil was on alert for a new virus more aggressive than COVID-19. The video misused AI tools to fabricate content, mixing a real broadcast with misleading messages. Burbulhan verified that there were no actual cases in Brazil, highlighting the danger of hybrid disinformation as AI tools advance, creating realistic yet false content.
A report from Observatório Lupa noted a 308% increase in AI-generated disinformation in Brazil since 2024, marking it as a significant issue ahead of the October elections. In 2024, AI was primarily used for scams, while in 2025, it spread across various domains, including politics and entertainment.
Experts emphasized that creating deceptive content has become widely accessible, making detection harder. Even with dedicated fact-checking teams, the realistic nature of AI-generated content means that assumptions about authenticity can no longer be made. The Superior Electoral Court is concerned about AI’s role in fake news and is considering imposing fines for its misuse. Efforts to combat this disinformation must evolve, as traditional denials struggle to gain traction against viral false narratives in a fast-paced information environment.
