Before you try to do your holiday shopping with an iPhone app, make sure that app is the real deal.
The fake apps included recognizable brands, from retail chains like Dollar Tree, department stores like Nordstrom and even designer brands like Christian Dior.
While some only offered endless pop-up ads, others asked users to enter credit card details or contained malware that could steal personal information.
Security experts told The New York Times that most fake apps are created in China and somehow manage to slip through Apple's review process, which looks at reliability and performance and ensures apps are free of offensive material.
In a statement, an Apple spokesperson responded to the issue of fake apps, saying "We've removed these offending apps and will continue to be vigilant about looking for apps that might put our users at risk."
Despite efforts to remove them, imitation apps keep popping up. To keep their apps in the store or to get new ones in, developers are changing their apps' content after the apps have been approved, or they're resubmitting similar products after fakes have been uncovered.
Apple allows users to report suspicious apps. Fake apps tend to have no reviews and no history of previous versions, and often, their menus don't make sense or use poor English.
