A malware program created by a highly organized Chinese hacking collective has gained control of 85 million Android devices, which the group is exploiting to the tune of $300,000 a month. The group, which researchers say is responsible for developing the HummingBad malware campaign, represents a dramatic increase in the organization and capabilities of hacking groups, according to security firm Check Point.

The group is highly organized and works alongside a legitimate Chinese advertising analytics company, according to Check Point, which uncovered the connection between Yingmob and HummingBad, .

The group then uses that rootkit to generate fraudulent ad revenue and install additional fraudulent apps. Yingmob has 25 employees organized into four different groups who are responsible for developing HummingBad?EU?s malicious components, according to Check Point researchers.

The hackers try to root thousands of devices every day, and are able to successfully get its malware installed on devices hundreds of times each day. Yingmob can then use those devices to create a botnet, enabling the group to launch more targeted attacks against businesses and government agencies, or even sell the access it has gained on the black market.
All of which is very bad news for Internet security, Check Point said in its “From HummingBad to…
