"The indictment alleges that the defendants were part of a group that hacked computers in at least a dozen countries and gave China's intelligence service access to sensitive business information," said Deputy Attorney General Rod J. Rosenstein in a DOJ press release. "This is outright cheating and theft, and it gives China an unfair advantage at the expense of law-abiding businesses and countries that follow the international rules in return for the privilege of participating in the global economic system."

Zhang Shilong and Zhu Hua allegedly carried out these attacks as part of the hacking group Advanced Persistent Threat 10 (the APT10 group), and targeted a huge variety of companies and agencies. While the DOJ isn't releasing names of specific companies, it comes from a huge list of industries including: aviation, satellite and maritime technology, industrial factory automation, automotive supplies, laboratory instruments, banking and finance, telecommunications and consumer electronics, computer processor technology, information technology services, packaging, consulting, medical equipment, healthcare, biotechnology, pharmaceutical manufacturing, mining, and oil and gas exploration and production.

The Washington Post reports that the US wasn't the only target in this extensive campaign -- Britain, Japan, Canada, Australia, Brazil, France, Switzerland and South Korea were also among the targets of this Chinese hacking group. Because of the global nature of the attack, the Post says that US and "more than a dozen" allies are expected to condemn China for ongoing attempts to steal trade secrets and compromise various government agencies.

This comes at a time when China / US relations are increasingly fraught, especially in the technology sector. Earlier this year, the DOJ charged ten individuals for stealing intellectual property relating to jet engine design, and last week it was revealed that Chinese hackers successfully targeted Navy contractors multiple times over the last 18 months. It appears that today's charges are unrelated, but the US and China have also been at odds for months in trade negotiations, with the White House threatening to levy large tariffs on Chinese goods as a way to pressure the country into stopping what the US deems unfair trade practices. Further complicating matters is the recent arrest in Canada of Huawei CFO Meng Wanzhou at the request of the DOJ.

Rosenstein and details on the industries targeted in the hacking campaigns.
