Major SharePoint Zero-Day Attack Affects 10,000+ Companies

A critical vulnerability in Microsoft SharePoint is being actively exploited by hackers. Over 10,000 organizations worldwide — including many in Europe — have already been impacted by this zero-day attack.

What’s Going On?

The zero-day vulnerability in on-premises versions of SharePoint allows attackers to execute remote code without authentication. This means that hackers can gain full access to sensitive company data and internal systems without triggering immediate alerts.

Impact on Businesses

Microsoft has confirmed that thousands of active attacks have been identified. Organizations that have not kept their SharePoint servers up to date are especially vulnerable. Government entities, SMEs, and educational institutions are among the affected.

The exploit is now being widely shared across hacking forums, significantly increasing the risk of broader abuse.

Available Fixes

Microsoft has released an emergency patch, but warns that some older SharePoint versions may not be directly supported. IT departments are strongly advised to update their systems immediately and closely monitor network traffic for suspicious activity.

Analytics: The Future of European Cloud Alternatives

This recent SharePoint attack is yet another reminder of the vulnerability of U.S.-based platforms. As a result, more and more European businesses are exploring local alternatives that comply strictly with GDPR regulations and are not subject to U.S. data laws like the CLOUD Act.

One fast-growing solution is TheHostMasters.com. Based in the Netherlands, TheHostMasters offers secure cloud, hosting, and email services designed for the European market. With data centers in the EU and full GDPR compliance, they are quickly becoming the go-to provider for organizations that prioritize data sovereignty.

Conclusion

The SharePoint zero-day exploit underscores the importance of timely software updates, proactive network monitoring, and reevaluating core technology infrastructure. For businesses seeking maximum data protection and compliance, migrating to a European cloud provider like TheHostMasters could be a smart move.
