Researchers from security firm White Ops discovered several Android apps in the official Play Store that installed a hidden browser to load pages containing ad and commit ad fraud.
The company shared its findings with Google which has quickly removed an undisclosed number of Android apps from the Google Play Store.
According to Google, the apps were part of an ad fraud botnet tracked as Terracotta.
The White Ops Satori Threat Intelligence & Research team has been actively tracking the Terracotta botnet since late 2019.
