Chinas WeChat Monitors Overseas Users to Bolster Censorship at Home, Report Says

International users of Chinese messaging app WeChat could be helping the platform tighten its censorship system for users inside China, according to the latest report by digital watchdog Citizen Lab.

The app, with over 1 billion monthly active users worldwide, is known to censor its users in China to ensure content falls within topics deemed acceptable by the Chinese Communist Party.

The report, however, found that communications between users outside of China are also monitored to help refine the apps censorship algorithm for its users in China.

The findings revealed that overseas users are subject to “pervasive content surveillance that was previously thought to be exclusively reserved for China-registered accounts,” Citizen Lab said.

Around 100 million people hold WeChat accounts registered outside of China, according to Munich firm Messenger People.

Inside China, the app offers a multitude of services ranging from chatting, shopping, marketing, banking to booking movie tickets and taxis.

Feeding a Censorship Apparatus

The report found that WeChat will screen images and documents that overseas users share with each other to build up a database it uses to censor its China-based users.

The researchers reached these finds based on experiments conducted between November 2019 and January. They set up two group chats: one containing only overseas users, and another containing overseas users and one China-registered account.

They found that when they sent politically sensitive images and documents in the chat solely containing overseas users, shortly after those files would be censored for China-registered users.

WeChat also retains data of the files that users delete in the app and therefore never received by the other party, the researchers found.

“[N]one of the information WeChat makes available to users explains the rationales for such surveillance,” the report concluded, noting that WeChats data protection staff never fully addressed the researchers questions regarding the companys data handling practices.

Tencent, Shenzhen-based tech giant that owns the app, said in a statement on Friday that “with regard to the suggestion that we engage in content surveillance of international users, we can confirm that all content shared among international users of WeChat is private.”

While further technical analysis is necessary to determine if the same red flags are present among other Chinese firms, its “plausible that other platforms use surveillance similarly,” according to Jeffrey Knockel, a postdoctoral fellow at the institute who co-authored the report.

He suggested that privacy regulators could issue fines to companies for misleading users. In Canada, residents could also complain to federal privacy regulators who could “provide non-binding recommendations for how the company must modify its services,” Knockel said.

Concerns Around Chinese Apps

The report adds to a growing chorus of criticism over the censorship and data handling practices by Chinese social media platforms.

In a March report, Citizen Lab found that WeChat in China actively censored discussion on the outbreak from January. It identified 516 keyword combinations directly related to the virus on a WeChat blacklist, including references to the whistleblower doctor Li Wenliang, who died of the disease.

In late April, Sens. Ted Cruz (R-Texas) and Josh Hawley (R-Mo.) introduced a bill, titled “Countering Chinese Attempts at Snooping”, which aims to ban federal employees from using tech platforms that are subject to control of the Chinese Communist Party. Tencent is one of the Chinese companies on the list.

“Companies like Tencent and Huawei are espionage operations for the Chinese Communist Party, masquerading as telecom companies for the 21st century,” Cruz said in a press release. He added that stopping taxpayers dollars from contributing to these platforms are “common sense measures to protect American national security.”
