The Joker strikes again! No, it’s not in the form of Batman’s archnemesis, but in a clever bit of malware that has infected dozens of Android operating system apps. The malicious code can easily avoid detection unless you pay close attention to your bank and credit card statements.

How Joker Malware Works

Joker works by silently signing you up for subscription services that you never wanted in the first place. In Denmark, for example, Joker was responsible for signing some people up for subscriptions at 50 Danish kroner per week (or roughly seven euros).

Google has since removed the offending apps from the Google Play store, but not before the apps had been downloaded more than 472,000 times.

Fortunately for many of our readers, a majority of the infected apps target European and Asian countries, including China, Brazil, France, United Arab Emirates, Singapore and the UK. Interestingly, some of the Joker’s code comments are written in Chinese, which might give a hint as to the malware’s origin.

Which Android Apps Are Affected?

One final warning: Joker uploads your entire phone’s contact list to the bot’s makers, so you may want to inform your contacts that you may have been infected.
