The Chinese government denied its operatives were behind a massive data breach of a credit reporting agency after the Justice Department charged four members of the Chinese military for their role in the 2017 Equifax hack.

“The Chinese government, military, and relevant personnel never engage in cybertheft of trade secrets,” Foreign Ministry spokesman Geng Shuang said Tuesday, according to the Washington Post. “We firmly oppose and combat cyberattacks of any kind. China is a staunch defender of cybersecurity.”
