Patch Too Late? Microsoft SharePoint Zero-Day Breach Expands Worldwide

August 2, 2025

The discovery of a critical zero-day vulnerability in Microsoft’s SharePoint server has exposed the fragility of digital infrastructure relied upon by schools, hospitals, government agencies, and critical service providers worldwide. What began as a sophisticated intrusion by Chinese state-linked groups has quickly spiraled into a global wave of exploitation, drawing in both organized cybercriminal gangs and opportunistic hackers. At stake is not only the confidentiality of sensitive data, but also the operational resilience of institutions least equipped to defend themselves. Even with Microsoft’s urgent patch now available, experts warn that many victims remain compromised, facing a long and uncertain process of detection, remediation, and recovery.
