Over 1,000 fraudulent ads impersonate Brazil's Desenrola debt relief program

Between July 19 and 21, researchers at the Federal University of Rio de Janeiro's Internet and Social Media Studies Lab discovered over one thousand fraudulent advertisements circulating across Meta's platforms—Facebook, Instagram, and Messenger—all impersonating Brazil's Desenrola debt relief program. The scale of the deception was staggering, but what made it more troubling was how effectively it had evaded detection. Most of these ads slipped past Meta's moderation systems entirely, operating below the threshold of traditional monitoring. They remained active even after journalists and television stations began reporting on the scams.

The fraudsters had weaponized the government's own credibility. The fake ads borrowed the visual identity of federal institutions and Serasa, the country's credit bureau, lending themselves an air of legitimacy that made them devastatingly effective. The researchers, in a report titled "Advertising in Service of Indebtedness," noted that the scams caused direct financial harm to potential program beneficiaries—people already vulnerable, already struggling with debt. What made this worse was that Meta's own advertising library, which archives all promoted content on the company's platforms, contained the evidence of these crimes, yet the company's systems had failed to stop them.

The timing of the fraud was not accidental. On July 17, the Brazilian government had launched the first phase of Desenrola Brasil, a program designed to allow 70 million Brazilians in default to renegotiate their debts with financial institutions on better terms. This came against a backdrop of widespread financial distress: a May study by the National Confederation of Commerce found that roughly 78 percent of Brazilian families were already in debt. The program represented genuine relief for millions of people. The fraudsters saw an opportunity.

Meta responded to the discovery with a statement insisting it does not permit fraudulent activity on its services and that it removes deceptive ads about Desenrola as soon as they are identified through a combination of technology, user reports, and human review. But the researchers at UFRJ saw a deeper problem. The company had made it possible to create fake pages in the name of the federal government without requiring verification of advertisers—leaving consumers with no reliable way to distinguish authentic from counterfeit. The platforms themselves had built the vulnerability into their systems.

The Brazilian Federation of Banks, Febraban, issued its own alert with practical guidance. Do not click links sent through messaging apps, social media, or sponsored search results, the federation advised. Contact your bank directly. Be suspicious of anyone asking you to send money upfront to secure better renegotiation terms. Use only the official channels—bank branches, internet banking, official apps—and when accessing internet banking, type the bank's address yourself rather than following a link. If you receive any message bearing the Febraban logo or a bank's logo, discard it and call the bank directly.

But the researchers saw the real issue as systemic. Self-regulation by the platforms had not worked. The study called for mandatory regulation of digital platforms that would impose transparency requirements and hold companies accountable for their services while respecting Brazil's Consumer Protection Code. The platforms, the researchers argued, were profiting from fraudulent ads even after removing them—the revenue from the deception made them, in a sense, beneficiaries of the crime. Until regulation forced them to prioritize public interest over their own financial gain, the cycle would continue. Desenrola Brasil was meant to help people escape debt. Instead, it had become a hunting ground for those who wanted to exploit them.
