Here’s what you should know about the Judy malware:

What is Judy and how does it work?
Judy malware is a virus that basically produces fake click on the advertisements in the app so that its perpetrators can earn revenue from the app developers.

Judy works by bypassing Bouncer, which is a tool Google uses to secure its app. Judy creates a seemingly harmless connection between the infected device and the attackers, which essentially delivers the malicious payload. The malicious payload includes JavaScript code, URLs by the attackers and a user-agent string.

Judy then opens the URLs using the user-agent string that mimics the web browser of the infected system and is used to launch the targeted websites. Once the targeted website is launched, Judy uses the JavaScript code to locate the infected device and click on the advertisement based on the Google ads infrastructure.
