Recently security firm Check Point had revealed that more than 40 apps developed by a Korea-based company had infected devices to generate large amounts of fraudulent clicks on advertisements, generating revenues for the perpetrators behind it.

The malware said to have affected more than 36.5 million android users although Google removed the application from Play Store after receiving reports regarding the application. However, the security firm has pointed out that the applications were spread faster than expected. The company said, “It is unclear how long the malicious code existed inside the apps, hence the actual spread of the malware remains unknown.”

“Once a user downloads a malicious app, it silently registers receivers which establish a connection with the [Command and Control] server. The server replies with the actual malicious payload, which includes JavaScript code, a user-agent string and URLs controlled by the malware author. The malware opens the URLs using the user agent that imitates a PC browser in a hidden webpage and receives a redirection to another website. Once the targeted website is launched, the malware uses the JavaScript code to locate and click on banners from the Google ads infrastructure.”


“Hackers can hide their apps’ real intentions or even manipulate users into leaving positive ratings, in some cases unknowingly. Users cannot rely on the official app stores for their safety, and should implement advanced security protections capable of detecting and blocking zero-day mobile malware.”

While the company also develops android applications, Check Point haven’t revealed any problem with the iOS application.
