Criminals pretend to be technical support professionals and deceive Brazilians | Security

Brazilian users and companies are still victims of fraud under the pretext of technical support. According to a study by Microsoft's Digital Crimes division in several countries, the number of such successful scams in Brazil fell between 2016 and 2018, but 66% of people have had contact with the practice. Of the cases recorded this year, 5% resulted in a loss of money, less than the 12% in 2016.

In these criminal schemes, a hacker impersonates a support professional at a large technology company. By phone, e-mail or windows in the browser itself, he addresses a customer stating that his computer or cell phone is infected. The goal is usually to gain remote access to the device.

A good part of the Brazilians just ignored the hackers' attempt (43%), but a portion continued with the fraudulent contact, even if without financial consequences (19%). Others did not even interact with the fraudster (34%).

Brazil has statistics similar to the world average. In other countries, 63% of users are affected by technical support fraud attempts, of which 6% lose money. Economic damage, incidentally, is an important negative effect, but not only is the stress caused and equipment repair also cited. And the victims have different profiles, passing through different generations.

To avoid scams, according to the Microsoft report, it is necessary to understand the source of threats and how they reach people. It is also essential to keep your devices safe and to know what are the best tools to check the reliability of websites and emails.

Technology companies don't usually make contact with customers in this way, so be very careful if you receive a message or call asking for sensitive data. Do not pass on personal or banking information without being absolutely sure of the authenticity of your interlocutor.
