What is the Joker Virus?

The name itself is taken from one of the controlling servers (C&C) of the malware. The Joker virus has appeared since June this year.

This virus was first detected by a malware analyst from Canadian Security Intelligence Service (CSIS) named Aleksejs Kuprins.
According to him, this virus will carry out automatic interactions on advertising websites by simulating clicks and entering authorization codes to register for premium services.
The trick, this virus is able to enter the verification code that is usually sent via SMS. After that, the Joker virus will enter the code and authorize the subscription.
For example, there is a victim from Denmark who suddenly subscribes to a service that is not very clear at a price of 6.71 euros or equivalent to Rp104 thousand per week.
Furthermore, Kuprins said that some bot code comments were written in Chinese, so that it could be one of the origin clues of the Joker virus.
