Four games in particular – Agent Shooter, Rainbow Stretch, Rubber Punch 3D, and Super Skibydi Killer – stood out for their use of a trojan designed to exploit intrusive ads. Some of the games had more than 500,000+ downloads each, and the authors went to great lengths to keep their nefarious nature hidden from users.
As Dr. Web notes, the games would replace their icons on the home screen with transparent versions and leave their name field blank to avoid detection. Some also used a Chrome web browser icon, and would launch trojans that would run in the background when opened to generate fraudulent ad revenue.
