Google: Play Protect Cut Harmful Android App Installs by 20% in 2018

Speaking of the state of Android apps' security, Google today published its annual Android Security & Privacy Year in Review, a comprehensive report that details the company's ongoing efforts to keep over two billion devices running Android mobile operating system secure. From a report: Google says that Google Play Protect, Android's AI-driven built-in defense mechanism, substantially cut down on the number of Potentially Harmful Applications (PHAs) in Google Play. Last year, only 0.08 percent of devices that used Google Play exclusively for app downloads were affected by PHAs, and even devices that installed apps from outside of Play -- 0.68 percent of which were affected by one or more PHAs, down from 0.80 percent in 2017 -- saw a 15 percent reduction in malware. In fact, Play Protect prevented 1.6 billion PHA installation attempts from outside of Google Play in 2018, Google says [PDF]. Installation attempts outside of Google Play fell by 20 percent from the previous year, and 73 percent of PHA installations were successfully stopped compared to 71 percent in 2017 and 59 percent in 2016. In all, 0.45 percent of Android devices running Play Protect installed PHAs in 2018 compared with 0.56 percent of devices in 2017, equating to a 20 percent year-over-year improvement.
