Most of the 256 affected apps were made in China, but they were available worldwide on the app store and were downloaded 1 million times, according to app analytics service SourceDNA, which first discovered the problem. The apps' creators used a software development kit from a Chinese advertising company called Youmi, which allowed the developers to put ads in their apps.
