Corona virus COVID-19 used to steal bitcoin

in #bitcoin2 years ago

Cyber criminals are using fear and panic over the Corona virus, or COVID-19, to steal bitcoin and other cryptocurrencies using ransomware. Besides all kinds of shady domain registrations, many Android apps have appeared. Some of them come with ransomware, locking users out of their Android phone and forcing them to pay bitcoin. discovered there's a website called CoronaVirusApp(dot)site that prompts users to install an Android application. They promise real-time updates on the COVID-19 pandemic, but instead install a ransomware called 'CovidLock'.

CovidLock requests access to the lock screen. Once it gains access, it blocks users from getting access to their phone. The ransomware threatens to erase contacts, photos and videos, and to leak social media account information. The Corona virus ransomware will leak and erase everything, unless a 100 dollar ransom in bitcoin has been paid within 48 hours.

Since Android Nougat has rolled out, there is protection in place against this type of attack. However, it only works if you have set a password. If you haven't set a password on your phone to unlock the screen, you're still vulnerable to the CovidLock ransomware.
