"Microsoft has indicated that Chinese state-backed threat actors, including Linen Typhoon and Violet Typhoon, hacked into on-premises SharePoint servers that businesses use, exploiting vulnerabilities in the software."
"The US tech giant released security updates and urged all customers with on-premises SharePoint servers to install them promptly to mitigate risks associated with these attacks."
Chinese state-backed actors, including Linen Typhoon, Violet Typhoon, and Storm-2603, hacked Microsoft's SharePoint on-premises servers, targeting business data. Microsoft has confirmed these exploitations and issued security updates for affected customers. Investigations into other potential actors are ongoing, with a strong belief that hackers will continue targeting systems lacking these updates. Notable attacks involved hackers sending requests to SharePoint servers to steal sensitive key material. Charles Carmakal from Mandiant noted that various sectors around the globe, including government and businesses, were primarily targeted. The exploit occurred opportunistically before a patch was available, escalating its significance.
