How does an app from a no-name developer earn $80,000 per month on the App Store? Johnny Lin decided to find out. The app “Mobile protection :Clean & Security VPN” claims to scan your iPhone for viruses and malware, charging a whopping $99.99 for a 7-day subscription (it seems to have disappeared now). Of course, thanks to iOS sandboxing and other security features, malware isn’t a significant issue in Apple’s mobile operating system. Lin details how unethical developers are taking advantage of App Store tools and policies to bilk unsuspecting iOS users, and he offers suggestions for how Apple can solve the problem. It’s baffling that Apple approved apps like this in the first place — perhaps it’s a side effect of faster app review times. Until Apple removes these scam apps and improves its app review policies, spread the word to make sure family and friends don’t get ripped off!
