According to Sophos' researchers, the trick is to get people to subscribe to the service, and then forget they subscribed, or think they can unsubscribe by simply uninstalling the app. Faking app reviews and comments, as well as inflating download numbers, is also part of the deception. "With interest in AI and chatbots arguably at an all-time high, users are turning to the Apple App and Google Play Stores to download anything that resembles ChatGPT. These types of scam apps-what Sophos has dubbed 'fleeceware'-often bombard users with ads until they sign up for a subscription. They're banking on the fact that users won't pay attention to the cost or simply forget that they have this subscription. They're specifically designed so that they may not get much use after the free trial ends, so users delete the app without realizing they're still on the hook for a monthly or weekly payment."
