China's "censorship-as-a-service" operations have been exposed through a data leak, revealing that a Chinese cybersecurity company, TopSec, plays a key role in monitoring and controlling public opinion. The Shanghai Public Security Bureau has been identified as one of the main clients of this service.
TopSec, a Chinese cybersecurity company, has been exposed as a key player in China's "censorship-as-a-service" operations. The company provides bespoke monitoring solutions to government agencies and state-owned enterprises for detecting security issues and content changes. The Shanghai Public Security Bureau has partnered with TopSec for a cloud monitoring service project, designed to detect hidden links and sensitive words in web content. The data leak reveals TopSec's use of industry-standard tools and frameworks, including Ansible and Sparta, to implement censorship-as-a-service solutions. The involvement of private sector companies like TopSec raises significant concerns about the potential for censorship and surveillance in China.
In a revelation that sheds light on the inner workings of China's censorship regime, a data leak has exposed TopSec, a Chinese cybersecurity company, as a key player in the country's "censorship-as-a-service" operations. The leak, which was detected by SentinelOne researchers, contains infrastructure details, work logs, and references to web content monitoring services used to enforce censorship for public and private sector customers.
Founded in 1995, TopSec has long been perceived as a trusted cybersecurity provider, offering services such as Endpoint Detection and Response (EDR) and vulnerability scanning. However, according to SentinelOne researchers Alex Delamotte and Aleksandar Milenkoski, the company's true capabilities extend far beyond these traditional services. The data leak reveals that TopSec is providing bespoke monitoring solutions to government agencies and state-owned enterprises, including a recent contract with the Shanghai Public Security Bureau.
The Shanghai Public Security Bureau's "Cloud Monitoring Service Project," announced in September 2024, involves continuous monitoring of websites within the Bureau's jurisdiction to identify security issues and content changes. The platform has been designed to detect hidden links in web content, as well as those containing sensitive words related to political criticism, violence, or pornography.
The manner in which this information is being used remains unclear, but SentinelOne researchers suggest that it could be used by customers to take follow-on actions, such as issuing warnings, deleting content, or restricting access when sensitive words are detected. This raises significant concerns about the potential for censorship and surveillance in China, particularly given the country's reputation for strict online controls.
"The main file we analyzed contains numerous work logs, which are a description of the work performed by a TopSec employee and the amount of time the task took, often accompanied by scripts, commands, or data related to the task," the researchers noted. "These leaks yield insight into the complex ecosystem of relationships between government entities and China's private sector cybersecurity companies."
The researchers further highlighted that while many countries have overlap between government requirements and private sector cybersecurity firms, the ties between these entities in China are much deeper and represent the state's grasp on managing public opinion through online enforcement.
"In addition to work logs, the leak contains many commands and playbooks used to administrate TopSec's services via multiple common DevOps and infrastructure technologies that are used worldwide, including Ansible, Docker, ElasticSearch, Gitlab, Kafka, Kibana, Kubernetes, and Redis," they added. "These findings suggest that TopSec is using industry-standard tools to support the implementation of censorship-as-a-service solutions."
Furthermore, references found in the data leak indicate that TopSec is utilizing a framework named Sparta (or Sparda) for handling sensitive word processing by receiving content from downstream web applications via GraphQL APIs.
The implications of this revelation are far-reaching and underscore the complex nature of China's cybersecurity landscape. As the country continues to tighten its online controls, the involvement of private sector companies like TopSec raises significant concerns about the potential for censorship and surveillance.
In recent years, China has been increasingly using "censorship-as-a-service" operations to monitor and control public opinion. The data leak exposed by SentinelOne highlights the extent to which this is taking place, with a Chinese cybersecurity company serving as a key player in this effort.
The full scope of this operation remains unclear, but one thing is certain – the involvement of private sector companies like TopSec in China's censorship regime raises significant concerns about the potential for censorship and surveillance.
