According to a recent report, the Ghost Push family of malware is responsible for most of the Android infections. The malware is typically spreading via deceptive adverts and pornographic websites. At its peak, Ghost Push was infecting over 600,000 Android devices each day. The current version of Ghost Push can root all versions of Android from version 5 (Lollipop) and earlier. Only users running version 6 (Marshmallow) and version 7 (Nougat) are safe at this time. According to Google's latest platform statistics (dated Sept. 5), only 18.7 percent of Android users are on version 6.0 or higher. Yet again, another reason to upgrade your devices so they can run the latest operating system.
