Microsoft has pointed the finger at three Chinese nation-state actors. Here's what we know, plus how to guard against future attacks.

In ongoing hacks, Microsoft says it has identified two Chinese hacking groups taking advantage of a key software flaw.

OpenAI CEO Sam Altman says the company will surpass 1 million GPUs by the end of 2025, but his sights are set on 100 million. Already backed by the world’s largest AI data center in Texas, OpenAI’s infrastructure push highlights the growing clash between AI ambitions and power grid realities.

Federal cybersecurity officials have issued a warning to Microsoft users about a security flaw allowing hackers to access to certain SharePoint systems.

Microsoft said the company has been "coordinating closely with CISA, DOD Cyber Defense Command, and key cybersecurity partners around the world throughout our response."

Microsoft’s first patch for a major SharePoint bug failed, leading to a cyber espionage spree affecting up to 9,000 servers, with China-linked actors named among the groups exploiting it.
