Ars Technica: "Last weekend there were reports that iTunes and the App Store had been hacked. However, it turned out that a developer had used other users' iTunes accounts to buy his apps repeatedly, quickly moving the apps up the App Store sales ranking. It now appears that another developer, WiiSHii Network, has started doing the same thing.
Ars reader Harper Reed contacted us to detail the problem. His account was used earlier today to purchase 34 of WiiSHii Network's apps without his permission, for a total of $168.89. The apps appear to mostly be travel guides for cities in China, and come in both English and Chinese versions—oddly enough, Reed ostensibly bought both."
