Kaspersky announces the availability of the Who Calls mobile app in Brazil, a solution aimed at protecting smartphone users from the growing wave of spam and phone call frauds. It is estimated that Anatel's actions have already prevented more than184.9 billion unwanted callsbetween June 2022 and December 2024 In this context, the app will help people identify and block unknown calls or potential scams, including on WhatsApp.
Brazil faces almost5 million attack attempts on mobile phones per day in 2024, and connections are a common pathway for traps that do not use malware. According to preliminary data from Kaspersky Who Calls, during the first five months of testing the solution, fraudulent calls increased from 2.19% in the first month (November 2024) to 10.12% in the fifth month (March 2025). Unwanted calls increased from 37.26% to 59.27%.
“In Brazil, there is an excess of commercial and advertising calls – so much so that there are measures aimed at blocking these excesses by Anatel, but there are also many scams, mainly motivated by financial gain. With Kaspersky Who Calls, we have a proactive digital shield for people to block both calls. With our artificial intelligence, we can quickly learn and identify new formats of nuisance calls and scams, transforming people's experience into an informed decision. We want Brazilians to regain control of their communication without giving up their security.“, Leonardo Castro, director of e-commerce at Kaspersky in Latin America, affirms.
