According to analysis from Alibaba Cloud Security experts, the blackmail incident spread rapidly across campus networks, the main reason being that most campus networks are basically a large interconnected LAN, and security zones were not defined for different applications. For example: student management systems, educational administration systems, etc. can be accessed through any connected device.
At the same time, IP addresses allocated for machines in labs and multimedia classrooms are mostly public IP addresses, so if the schools hadn't implemented the relevant permission restrictions, all the machines would be directly exposed.
In fact, not only campuses networks in China that were attacked but also campuses across the globe. According to the BBC, a large number of agencies worldwide in the United States, Britain, China, Russia, Spain, Italy, Vietnam and other places have reported attacks from "blackmail" software.
