BlockBeats News: On May 19th, according to Blue Dot Network, Procolored, a printer company in Shenzhen, China, was found to have provided official drivers with backdoor programs to steal cryptocurrency. The data shows that the number of bitcoins stolen by hackers reached 9.3.
The cause of infection is the innate use of USB drives to transfer these drivers, and after being infected with backdoor programs, they were naturally uploaded to a cloud drive for global users to download.
