US charges two Chinese spies for a global hacking campaign that targeted COVID-19 vaccine research

U.S. prosecutors have charged two wanted Chinese nationals linked to Beijing for their alleged involvement in a global hacking operation that targeted hundreds of companies and governments for more than a decade, stealing sensitive information.

The 11-count indictment unsealed on Tuesday, July 22, alleges Li Xiaoyu, 34, and Dong Jiazhi, 33, said to be working for China’s state intelligence bureau,stole terabytes of data from high-technology companies, around the world including the United States, the prosecutors said.

The prosecutors accused the hackers of recently targeting the networks of over a dozen U.S. companies in Maryland, Massachusetts, and California developing vaccines and treatments for COVID-19.

The indictment comes just weeks after both the FBI and Homeland Security warned that China was actively trying to steal U.S. research data related to the coronavirus pandemic.

The hackers were first discovered after they targeted a U.S. Department of Energy network in Hanford, Washington, the Justice Department said.

The prosecutors said the hackers also targeted companies in Australia, South Korea, and several European nations, using known but unpatched vulnerabilities in widely used web server software to break into their victims’ networks. By gaining a foothold onto the network, the hackers installed password-stealing software to gain deeper access to their systems.

The prosecutors also said that the hackers would “frequently” return to the networks — in some cases years later.

According to the indictment, the hackers stole “hundreds of millions of dollars” worth of trade secrets and intellectual property. The prosecutors also allege that the hackers stole data related to military satellite programs, military wireless networks and high-powered microwave and laser systems from defense contractors.

The hackers are said to have targeted their victims on behalf of China’s intelligence services, but also hacked for personal financial gain.

In one case, prosecutors said the hackers “sought to extort cryptocurrency” from a victim company by threatening to publish the victim’s stolen source code online.

John C. Demers, U.S. assistant attorney general for national security, said that the indictments were “concrete examples” of how China used hackers to “rob, replicate and replace” non-Chinese companies in the global marketplace.

Demers also accused China of providing a safe-haven for the hackers.

“China has now taken its place, alongside Russia, Iran and North Korea, in that shameful club of nations that provide a safe haven for cyber criminals in exchange for those criminals being ‘on call’ to work for the benefit of the state, here to feed the Chinese Communist party’s insatiable hunger for American and other non-Chinese companies’ hard-earned intellectual property, including COVID-19 research,” said Demers.

Mandiant, the incident response division of security firm FireEye, said it has tracked the hackers since 2013 and the tactics, techniques, and procedures used by the hackers is “consistent” with its findings.

“The Chinese government has long relied on contractors to conduct cyber intrusions,” said Ben Read, senior manager of analysis at Mandiant, in an email. “Using these freelancers allows the government to access a wider array of talent, while also providing some deniability in conducting these operations.”

“The pattern described in the indictment where the contractors conducted some operations on behalf of their government sponsors, while others were for their own profit is consistent with what we have seen from other China-nexus groups such as APT41,” he said, referring to the Chinese advanced persistent threat group associated with the indictment.

If prosecuted, the wanted hackers could each face more than 40 years in prison. But prosecutors believe the hackers are in China, and extraditions to the U.S. are unlikely because of the strained relationship between China and the US.
