Brazil's 2025 Black Friday saw 29,000 fraud attempts worth R$30.7 million in e-commerce
A report by Serasa Experian's Mapa da Fraude shows that Brazilian e-commerce recorded nearly 30,000 fraud attempts during the four-day 2025 Black Friday period, linked to estimated losses of R$30.7 million. The average fraudulent transaction value was R$1,034.77, about 45% higher than legitimate orders, and fraud activity spiked overnight between midnight and 5 a.m. Including Cyber Monday, the total reached 36,300 fraud attempts, and across all of November 2025 nearly 180,000 attempts were recorded, totaling R$161.4 million in associated losses. A September 2026 survey found consumers most fear fake websites (53%), Pix scams (42%), and fraudulent social media ads (32%), while digital threat records rose 99% during Black Friday week compared to prior weeks.
Detalhes técnicos
Fraudsters reportedly used low-cost items like shoelaces to test stolen payment card validity before attempting larger purchases (e.g., consoles and refrigerators). Generations Y and Z accounted for 71.6% of identified fraud attempts by age group.
Remediação
Serasa Experian recommends consumers be wary of prices far below market value and urgency-driven offers, verify site URLs by typing official addresses directly into browsers, avoid links from unknown senders, never share passwords or authentication codes outside official channels, verify seller identity and payment/delivery terms on marketplaces, use strong unique passwords, and monitor bank activity and CPF inquiries.
