Back on Google Play Store
The Joker virus became famous in 2017 when it infected and robbed its victims by hiding in different applications.
Since then, the Google Play Store defense system has removed about 1,700 apps containing the “Joker” virus before users downloaded them.
In September 2020, the ‘Joker’ virus was found in 24 Android apps that had been downloaded with over 500,000 downloads before they were removed.
At the time, the Joker virus was suspected to have spread to more than 30 countries including the United States, Brazil and Spain.
With unauthorized subscriptions and without the phone owner’s knowledge, hackers can steal up to US$7 (about Rs 100,976) per weekly subscription.
Immediately check for suspicious applications
The Joker virus hidden behind the app will blow your mind because they are able to automate payments without the need for any interaction.
“You risk a big surprise at the end of the month in your bank account or credit card,” Belgian police said.
So, Joker virus prevents users from knowing that their money is being stolen until they review their account details in detail.
This is because banks do not seem to be suspicious of “normal” subscriptions, and in general, the bills are very small. So it isn’t detected as unusual traffic, and it doesn’t even send usage alerts to account holders.
