This new malware is nothing to laugh about, even if it does go by the name Joker. A handful of Android apps have made their way onto the Play Store infected with a sneaky bit of malware hidden among the code. 

This particular brand of nastiness is designed to silently sign you up for subscriptions, using your credit card to fund unknown services, something you might not notice unless you’re regularly tracking your credit card statements.

Cyber-sercurity company CSIS’ Aleksejs Kuprins states:

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.” (Lifehacker)

While Google has removed the apps infected with the malware, almost 500,000 users downloaded the apps before they were taken down. The list of offending apps can be found below:

 

If you’ve downloaded or used any of these recently, make sure you check your statements and see if any unrecognisable purchases have been made recently. If you have, make sure you cancel them and see if you can get your money back.
