In late July 2026 police in São Paulo reported low‑level scams on Facebook Marketplace and WhatsApp that tricked users into PIX transfers, costing victims thousands of reais. A week later federal investigators uncovered an organized‑crime network that siphoned about R$45 million from Caixa Econômica Federal customers, including FGTS beneficiaries and emergency‑aid recipients. The ring, led by Jader Henrique Areas de Almeida in Rio and supported by data handlers in São Paulo, obtained a sealed judicial decision through Justice Federal employee Jackson Cozendey, attempted to destroy evidence, and moved funds through a British Virgin Islands offshore company and cryptocurrency.

On 3 August a new phase of Operation Sem Desconto was launched, with 18 search and seizure warrants in the Federal District and Maranhão, authorized by Supreme Court minister André Mendonça. Targets included Senator Weverton Rocha’s wife, daughter and sisters, and lawyer Willer Tomaz, whose aircraft was also seized. Investigators allege the scheme diverted up to R$6.3 billion from INSS benefits, with more than R$11 million transferred to the senator’s wife and a R$6 million house in Brasília bought through a company owned by Tomaz. Authorities say Rocha, a Senate vice‑leader and ally of President Lula, coordinated demands and oversaw payments, while Tomaz denies involvement. The Federal Public Ministry and the Attorney General’s Office have criticized the raids, suggesting less intrusive measures.

All incidents have been filed as estelionato, highlighting the challenge for Brazilian authorities to combat both small‑scale digital scams and high‑level political financial misconduct.
