The attacks on bank data occur mostly through phishing, when users of digital banking services download fake applications in online stores. With a close layout, this malicious software looks legitimate, but takes advantage of the victim’s carelessness to steal personal information, bank details and money from digital accounts.

Kaspersky security expert Victor Chebyshev warns that «in this period of social detachment and lockdown, we are all using our mobile devices more to access financial services», so caution must be doubled. Kaspersky also offers tips on how to prevent and avoid scams like those of banking trojans: avoid downloading applications outside the official virtual store, that is, only install apps offered by the Google Play Store or the App Store.
Still, caution is needed, as malicious apps can take advantage of flaws in the Android security system, abusing the permissions granted. Ideally, check the app’s information, such as the manufacturer and developer, and read user reviews on the Internet if you suspect the app is fake or malicious. Pay attention, too, to the permissions granted. If they are not in accordance with the proposal offered by the application, be suspicious.
