Pro-Beijing Online Campaign Targets U.S.-Based Xinjiang Researcher, Cybersecurity Firm Says

There is no evidence linking the activity to the Chinese government, Mandiant said, but the public-relations firm advertised its services as “positive energy packages.” State media in China have used the term “positive energy” to refer to the dissemination through social media of messages that promote Beijing’s views and policies.

who has sifted through large numbers of Chinese government documents to illuminate the mass detention and policing of Turkik Muslims in Xinjiang, the campaign manufactured website articles and a December

post. The tweet contained what Mandiant calls three fabricated letters purporting to show Mr. Zenz has received funding for his research from Sen.

(R., Fla.) and

Steve Bannon,

a former adviser to President

Donald Trump.

Several other social-media accounts and websites promoted the letters and referred to the Twitter account, purportedly by a person named Jonas Drosten. The account has since been suspended.

The allegations were then echoed by a purported Swiss news website and in a May article from the state-run newspaper China Daily.

The Chinese public-relations firm Mandiant named, Shanghai Haixun Technology Co., didn’t immediately respond to a request for comment.

Mr. Zenz, who is now based in the U.S., didn’t immediately respond to a request for comment.

The Chinese government has targeted the Xinjiang region’s mostly Muslim ethnic minorities with mass-detention internment camps and omnipresent surveillance as part of a yearslong campaign of forcible assimilation. China says the campaign is an effort to fight religious extremism and terrorism.

Chinese state-backed online campaigns have in the past spread pro-Beijing messages through a network of thousands of accounts on Western social-media services. Beijing has also taken out advertisements on Facebook purporting to show Muslim ethnic minority Uyghurs thriving in Xinjiang.

The use of a public-relations firm to seed messages on social media and on bogus news websites appears to be a growing trend, said Daniel Kapellmann Zafra, a senior analysis manager at Mandiant.

“The use of infrastructure from a third party is what makes this so interesting,” he said.

The public-relations firm hosted some 72 websites used to reach audiences in North America, Europe, the Middle East and Asia. Despite its complexity, Mandiant said the messages failed to attract significant public engagement.

The online campaign Mandiant uncovered has also included the assertion that there is widespread public support in Hong Kong for new electoral rules that give Beijing decisive control over how the city picks its leaders and legislators, and criticism of exiled Chinese businessman

Guo Wengui,

a prominent critic of China’s Communist Party.

Other material included an article, purportedly written by an American woman living abroad just days after the Supreme Court in June overturned the Roe v. Wade decision, alleging U.S. law enforcement committed violence against those protesting the decision.

A Ukrainian language article alleged numerous Ukrainians have been killed by purported U.S. biolabs in Ukraine, Mandiant said.
