WeChat Surveils International Accounts To Decide What To Censor for Chinese Users, Study Says

WeChat, the Chinese messaging app, is systematically monitoring the content sent by international users to build up its censorship algorithms applied against accounts registered in China, a new study has found. From a report: Researchers at Citizen Lab, an academic research lab at the University of Toronto, determined that WeChat screens images and documents shared by accounts registered outside China after they are sent, then adds the digital signature -- or "hash" -- of any files deemed sensitive to a blacklist. Those files then cannot be sent or received by China-registered users. Numerous studies have identified WeChat's use of censorship tools against China-linked accounts, but this research provides proof for the first time that non-China registered users are also swept up in its surveillance apparatus. Published Thursday in a report called "We Chat, They Watch," the Citizen Lab findings are likely to add fuel to existing concerns, particularly in Washington, about data security and the international reach of information control tools used by Chinese tech companies.
