JOKERJoker

Joker is a trojan that is included in several unsuspecting apps that have been offered via the Google Play Store, among others. The malware silently interacts with ad networks to perform clicks on ad banners and subscribe to paid premium services. To do this, Joker is able to read SMS messages, contact lists and device information from the victim system. It collects data from infected systems, intercepts sensitive communications and transmits the information to a remote attacker.
