Chinese state actors have recently abused vulnerabilities in the JavaScriptCore component of WebKit to hack the personal computing devices of Uighur Muslims in the Xinjiang region of China. Mass digital surveillance is a key component of China’s ongoing brutal human rights crackdown in the region.

This has resulted in a public relations drama that is largely a distraction to the issue at hand. Whatever big-company PR departments have to say on the matter, I have no doubt that the developers working on WebKit recognize the severity of this incident and are grateful to Project Zero, which reported these vulnerabilities and has previously provided numerous other high-quality private vulnerability reports. (Many other organizations deserve credit for similar reports, especially Trend Micro’s Zero Day Initiative.)

WebKit as a project will need to reassess certain software development practices that may have facilitated the abuse of these vulnerabilities. The practice of committing security fixes to open source long in advance of corresponding Safari releases may need to be reconsidered.

Sadly, Uighurs should assume their personal computing devices have been compromised by state-sponsored attackers, and that their private communications are not private. Even if not compromised in this particular incident, similar successful attacks are overwhelmingly likely in the future.
