Reportedly 10 million Android phones all over the world have been infected by a malicious app called Hummingbad. Developed by an otherwise legitimate app development company called Yingmob in China, Hummingbad gains root access of the infected Android device. It either gets the root access automatically or tricks you into giving it the needed system-level access and once the access is granted, it can trick your phone into generating fraudulent clicks on advertisements. According to some estimates, it is generating revenue of $300,000 per month for the developers.

Incidentally, some people are also calling it Hummingbird malware whereas it is not Hummingbird, it is Hummingbad.

The Hummingbad malware doesn’t just trick you into clicking ads, it also obtains confidential information from your Android mobile phone and then gives this information to the malware developers who sell this information then to the highest bidders.

According to the cyber security software maker Check Point based in Israel, all over the world 85 million smartphones have apps from Yingmob, although a very small margin of these apps are infected with the Hummingbad malware.

Here is a detailed description of the Hummingbad malware on the Check Point blog (PDF).

Here is a small extract from the PDF report above:

“While profit is powerful motivation for any attacker, Yingmob’s apparent self-sufficiency and organizational structure make it well-positioned to expand into new business ventures, including productizing the access to the 85 million Android devices it controls. This alone would attract a whole new audience — and a new stream of revenue — for Yingmob. Quick, easy access to sensitive data on mobile devices connected to enterprises and government agencies around the globe is extremely attractive to cybercriminals and hacktivists.”

Most of the victims are in China and India. Hummingbad malware has mostly infected the KitKat and Jelly Bean versions of Android. Only 1% of the devices running Android Marshmallow have been infected.
