China hackers attacked U.S. infrastructure

Microsoft warned on Wednesday that Chinese state-sponsored hackers had compromised “critical” U.S. cyber infrastructure across numerous industries with a focus on gathering intelligence.

The Chinese hacking group, codenamed “Volt Typhoon,” has operated since mid-2021, Microsoft said in an advisory. The organization is apparently working to disrupt “critical communications infrastructure between the United States and Asia,” Microsoft said, to stymie efforts during “future crises.”

The National Security Agency put out a bulletin on Wednesday, detailing how the hack works and how cybersecurity teams should respond.

The attack is apparently ongoing. In an advisory, Microsoft urged impacted customers to “close or change credentials for all compromised accounts.
