Researchers at DomainTools have issued an alert about a malicious Android app that pretends to warn users about those infected with the COVID-19 Coronavirus in their vicinity. In truth, the app locks users out of their devices and demands that $100 worth of Bitcoin ransom payment is made within 48 hours. If payment is not made, the phone will be completely erased and pictures, videos, and social media accounts shared online. CovidLocks screen-lock attack will not work on devices running Android Nougat or higher (Android 7.0 or later) if an unlock password has already been set by the user.”]
