At least three TikTok profiles with more than 350,000 followers combined have been promoting multiple fraudulent mobile apps that generated $500,000 in profit. The scammy Android and iOS apps pretended to be games, music and wallpaper downloaders. Once installed, they would display ads aggressively and charge users between $2 and $10 for features that either don’t exist or don’t work properly, or for weekly subscription fees. The revenue generated this way has been estimated to be more than $500k.
