Uninstall These 24 Android Apps Infected with New 'Joker' Malware

Another day, another batch of Android apps that made it into the Google Play Store—accumulating hundreds of thousands of downloads—with some sneaky malware embedded in their code.

This time around, the malware is called “Joker.” As Aleksejs Kuprins writes over at the cybersecurity company CSIS, this particular malware is designed to silently sign users up for subscription services, something they might not even notice they did unless they’re diligent in checking their monthly credit card statements.
He describes:

“For example, in Denmark, Joker can silently sign the victim up for a 50 DKK/week service (roughly ~6,71 EUR). This strategy works by automating the necessary interaction with the premium offer’s webpage, entering the operator’s offer code, then waiting for a SMS message with a confirmation code and extracting it using regular expressions. Finally, the Joker submits the extracted code to the offer’s webpage, in order to authorize the premium subscription.”
