Microsoft links Sharepoint attacks to Chinese hacking groups
Several hacking groups with ties to the Chinese government have been linked to a recent wave of widespread attacks targeting a Microsoft SharePoint zero-day vulnerability chain.
They used this exploit chain (dubbed "ToolShell") to breach dozens of organizations worldwide after hacking into their on-premise SharePoint servers.
"Microsoft has observed two named Chinese nation-state actors, Linen Typhoon and Violet Typhoon exploiting these vulnerabilities targeting internet-facing SharePoint servers," Microsoft said in a Tuesday report. "In addition, we have observed another China-based threat actor, tracked as Storm-2603, exploiting these vulnerabilities. Investigations into other actors also using these exploits are still ongoing."
