Microsoft is investigating whether a leak from its early alert system for cybersecurity companies allowed Chinese hackers to exploit flaws in its SharePoint service before they were patched, Bloomberg News reported on Friday.
Threat actors exploit SharePoint flaws to access internal systems, steal sensitive data, and carry out surveillance, impersonation, and extortion.
In a blog post on Tuesday, Microsoft said two allegedly Chinese hacking groups, dubbed "Linen Typhoon" and "Violet Typhoon," were exploiting the weaknesses, along with a third, also based in China.
A significant flaw in a widely used Microsoft product allowed multiple Chinese-linked hacking groups to breach dozens of organizations across the globe and at least two U.S. federal agencies.
