China state-backed Linen Typhoon and Violet Typhoon as well as China-based Storm-2603 were said to have "exploited vulnerabilities" in on-premises SharePoint servers, the kind used by firms, but not in its cloud-based service.

The US tech giant has released security updates in response and has advised all on-premises SharePoint server customers to install them.

"China firmly opposes and combats all forms of cyber attacks and cyber crime," China's US embassy spokesman said in a statement.

"At the same time, we also firmly oppose smearing others without solid evidence," continued Liu Pengyu in the statement posted on X.
