Researchers at Lookout found that the apps contained a version of the malware known as DroidDream Light, which is the same variant that was found in a batch of apps in June. The affected apps are Scientific Calculator, Quick FallDown, Bubble Buster and Quick Compass and Leveler. Researchers estimate that the malware-loaded apps only were downloaded by fewer than 5,000 users before Google removed them. The infected compass app has a name that s very similar to a legitimate app, with the difference being that the infected one uses capital letters in the name.
