100,000 Computers at Chinese Internet Cafes Hacked: Mining $800K Worth of Crypto
It has been recently come to our attention that a group of hackers managed to breach into Chinese internet cafes’ computers to mine cryptocurrency. The shock of it all is the fact that Chinese computer maintenance firms planned the whole scheme out with the hackers to make it happen.
The newsflash was reported by local news on June 16,2018, where Rui’An city police officials arrested 16 defendants who might have been involved. As for their success, the rather massive group was capable of getting hold of 5 million yuan worth ($800,000) by mining cryptos on over 100,000 computers situated across 30 Chinese cities. This hack has been an ongoing effort, as it the hackers have been mining illegally since July 2017.

The way in which the hackers were able to get into that many computers was by developing a piece of malware that automatically only mined Siacoin. This is where computer maintenance firms come into play, as they were responsible for implanting the malware into the systems at the internet cafes. The report also suggested that the profits made were split among those involved.
Many internet cafes in Rui’An were quick to notice several factors that resulted in a police report. What caught their attentions were as follows:
- Increased CPU usage rates which lead to slower computer speed
- Hikes in internet café bills
As for the arrest, the CEO of a computer maintenance firm was also one of the number of individuals detained in August. This is due to the fact that most internet cafes in Rui’An rely on the services of one key maintenance firm, which is yet to be disclosed.
According to the local report, the case is still ongoing, as 30 Chinese cities have been affected altogether.
