Brazilian authorities are promoting the use of the 'Celular Seguro' app to enhance mobile security during the Carnival festivities. The app allows users to quickly block their devices in case of theft, loss, or robbery, protecting financial apps and phone lines from criminals. The app now features a 'Recovery Mode,' enabling users to reuse their phones once recovered. Registration for the service is available via the app or online. Amid the Carnival celebrations, warnings have been issued about the increased risk of digital frauds, including scams involving PIX transactions and thefts. The Brazilian Federation of Banks (Febraban) advises consumers to temporarily disable contactless payment options on their cards to prevent unauthorized transactions. In a related incident, Brazilian TV presenter Rodrigo Faro was targeted in a virtual scam where a fraudster, using the image of advocate Lucas Collantoni, deceived him into sharing his bank account details during a video call. The scammer claimed Faro had won a legal case and needed to check his account for a supposed payment. Fortunately, there was no financial loss, and Faro took legal action following the incident. Security experts recommend verifying identities and being cautious with unsolicited requests to avoid such scams.
