In the last couple of months, we have covered multiple reports of hackers misusing COVID-19 global pandemic to prey on naive users to steal financial credentials and now in the latest development, cyber criminals have developed a malicious software-laced Coronavirus tracking Android app.

The COVID19 Tracker app is available for download on the website with the same namesake. If any user comes to the site, he/she will be asked to download the Android app for the heat map. It says to offer the information on the spread of the pandemic in addition to country-wise statistics of COVID-19 infections, recoveries and fatalities.

Once installed, the Coronavirus app, which houses ransomware 'CovidLock' takes full control of the phone and blocks the user from opening the screen lock.

"CovidLock uses techniques to deny the victim access to their phone by forcing a change in the password used to unlock the phone. This is also known as a screen-lock attack and has been seen before on Android ransomware," Tarik Salah, Senior Security Engineer and Malware Researcher at DomainTools, said in a statement.

It also threatens to leak social media account user IDs and passwords on public online platforms.
