Fake VPN and Spam Blocker Apps Tied to VexTrio Used in Ad Fraud, Subscription Scams
Briefly

VexTrio Viper has been identified as a malicious ad tech developer, creating fake apps that appear to offer utility but instead deceive users. These applications, including VPNs and spam blockers, are hosted on Apple and Google's official platforms, with millions of downloads. Users are often misled into subscribing to expensive services that are hard to cancel. Reviews indicate frustration with disruptive ads and unexpected charges, revealing a wider issue of consumer exploitation within the app marketplace.
These fake apps, once installed, deceive users into signing up for subscriptions that are difficult to cancel, flood them with ads, and part with personal information like email addresses.
One such Android app is Spam Shield block, which purports to be a spam blocker for push notifications but, in reality, charges users several times after convincing them to enroll in a subscription.
