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.
The company said state-backed hacking groups were breaching systems through flaws in SharePoint, which is used by the U.S. government and companies around the world.
Microsoft warns of hackers exploiting SharePoint vulnerabilities to breach critical organizations, including U.S. nuclear security.
Hackers have breached about 400 government agencies, corporations and other groups, according to estimates from Eye Security.
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.
