Google has removed dozens of applications from a famous Chinese developer in the Google Play Store. After a CheckPoint survey together with BuzzFeed was initiated, practical results that abused users ' licenses were found. The operation was carried out. DO Global, partly owned by Baidu (the Chinese Google), generated fraudulent clicks among various illicit practices to maximize profit. The developers involved are DO Global. Google announces that it has "seriously protect users and advertisers" and continues to invest in "tools and resources to fight fraud and infringements throughout the world." The company has stated that it "actively investigates and acts uncontestably when offenses are discovered, for instance by removing the ability of a developer to make money on his applications using the AdMob circuit or by preventing applications from being published on the Google Play Store." At least six DO Global apps for the study were found by the researchers who used "fake ad clicking practices," simulating user interaction with specific banners, even in the background or with the closed app. Before the ban, DO Global had around 100 applications on the Play Store, including a number of published apps with other names (e.g.. PreAMo (that's the name of the campaign) is composed of three fundamental tools, according to the note issued by Checkpoint, a computer security company. The tools are three different code blocks that interact with as many advertisers independently;' They are not code-connected because everyone is stored in a separate package and started by different actions.' The three codes are connected by communicating with the same server "C&C" (Command & Control) used to send statistics and receive configuration. However, the behavior of these three tools is similar. The "listener" element is recorded in a banner loaded into a publicity circuit and the MotionEvent feature in the Android frame used to simulate the click when the latter is downloaded.
