Google is expanding support for its Android's in-call scam protection to multiple banks and financial applications in the United States.
The announcement specifically mentions the addition of fintech app Cash App, which has 57 million users, and the JPMorganChase mobile banking app, which has more than 50 million downloads on Google Play.
In-call scam protection is a new feature that was announced in May and introduced in Android 16, Its purpose is to warn users of a potential danger when they launch a financial app and are sharing their screen while in a call with an unknown number.
Google says that this security feature defends against a popular scam where cybercriminals are "impersonating banks or other trusted institutions on the phone to try to manipulate victims into sharing their screen in order to reveal banking information or make a financial transfer."
In this scenario, an alert is shown, informing the user that the caller may be an impersonator and that the instructions they convey should be ignored. The user is also advised not to share any information or make any payments.
The warning pop-up persists for 30 seconds and the only option is to end the call. Google notes that the 30-second pause should break the attacker's social-engineering "spell," and disrupt the false sense of urgency and panic that are required for the scam to be successful.
