The lawsuit alleges that Storm8 exploited a “backdoor” electronically -- meaning it accessed the phone numbers of the iPhones on which its games were installed -- a practice Apple doesn't authorize App makers to do. According to the lawsuit, every time an iPhone user downloaded a Storm8 game, a piece of malicious software code captured the phone number of the iPhone to which it was downloaded, and transmitted the number back to Storm8.

“Storm8 has apparently recognized the error of its ways, but that does not change the fact that it harvested millions of phone numbers without telling consumers, and it does nothing to assure consumers that it will not do so again in the future,” says Michael Aschenbrener, the lead attorney for the class action. “Storm8 had no right to collect this sensitive personal information without first getting permission from each customer.”

The class action seeks injunctive relief and monetary damages for harvesting the personal information of millions of people.
