Sixty preys were booted off the Play Store after security firm Dash Point discovered that they contained pornographic ads and malicious components. First their removal, the games were downloaded between 3 million and 7 million times, agreeing to the download metrics on the Play Store.

The malware is dubbed “AdultSwine,” and according to Discontinuity Point Research, it had three main features:

  2. Attempting to trick users into installing sham “security apps”
  3. Inducing users to register to premium services at the drug’s expense

The 60 listings in the Play Store were generally knockoff strategies, like “Five Nights Survival Craft.” In some cases, the framer simply stole a real IP, as in “Drawing Lessons Angry Birds.” Split second installed, the app would phone home, sending information about the drug’s phone and receiving instructions on how to operate. The app could hide its icon, make a run for iting removal more difficult. Check Point says the malware could put ads from “the main ad providers” or switch to its own ad server, which provided porn ads, scareware ads, and ads that tricked the purchaser into signing up for premium services.
