More than 100 Play Store apps tried to infect Android devices with Windows malware

This was further corroborated by the fact that all seven of the developers were located in or near Indonesia, and many of the apps' names included the country's name, too. The hypothesis presented by the researchers is that the devs were infected from a common source with a malware that scans their hard disk for HTML files and injects them with malicious iframes. Thus, when uploading their apps to the Play Store, the included files were also infected.
Even if the malware included in the apps was Windows-specific and the domains it was supposed to be downloaded from were disabled a long time ago, this discovery is still somewhat problematic. Concealed iframes have been a well-known attack method for many years, and yet, Google's app screening process did nothing to flag these apps as potentially malicious. The Play Store has been known to contain malware in the past, too, leading to the question of whether current security procedures are enough, and whether Google even cares at all, seeing as it also systematically promotes useless adware on its storefront.
