They found a scheme in which a group of people operated a number of chat groups which promoted a plug-in called ‘World Internet Cafe’. The group was run by an individual called Yang Mobao.

Once installed, the plug-in displayed various advertisements for free downloads that would improve computer performance. This initial phase affected 3.89 million computers throughout the country. These downloads contained a hidden mining programme which initiates when it detects that the CPU is using less than 50 percent of the computer’s processing power. Approximately one million computers were infected with this software.

The investigation found that a company called Dalian Shengping Network Technology developed the software and spread it by selling network management software to internet cafes.

The scheme began in 2015 when the company’s financial director instructed the company’s head of operations to focus company resources on developing mining trojans. The customer service department is also implicated as employees were instructing customers on how to use the software.

Over two years, cryptocurrency worth 15 million yuan (2.2 million dollars) was mined. The money was divided amongst the group.
