Major tech company Microsoft has released urgent security updates to address multiple zero-day vulnerabilities in its SharePoint platform, following reports of global exploitation targeting sensitive data.
The flaws have enabled attackers to launch spoofing campaigns affecting government agencies, academic institutions, and businesses worldwide.
Microsoft hit with SharePoint attack
Microsoft confirmed it is actively tracking attacks targeting on-premises SharePoint Server customers, according to a recent blog post.
The company emphasized that the identified vulnerabilities affect only self-hosted SharePoint Server deployments and do not impact SharePoint Online users within the Microsoft 365 cloud environment.
Two critical SharePoint vulnerabilities—CVE-2025-53770 and CVE-2025-53771—were disclosed over the weekend by Dutch cybersecurity firm Eye Security, prompting Microsoft to release cumulative patches. The updates apply to SharePoint Server Subscription Edition, as well as the 2019 and 2016 versions, and aim to protect on-premises users from potential exploitation.
Furthermore, Microsoft issued guidance for organizations looking to mitigate potential exploitation of recently disclosed SharePoint vulnerabilities.
The company advises customers to ensure they are using supported versions of on-premises SharePoint Server, apply the latest security updates without delay, and deploy Microsoft Defender for Endpoint or a comparable threat protection solution.
Additionally, organizations should verify that the Antimalware Scan Interface (AMSI) is properly enabled and configured with an appropriate antivirus solution, such as Microsoft Defender Antivirus. As a final precaution, Microsoft recommends rotating the ASP.NET machine keys used by SharePoint Server.
More than 200,000 organizations and approximately 190 million users rely on SharePoint for content management, collaboration, and intranet services.
It is important to note, however, that these figures encompass both the cloud-based SharePoint Online and the on-premises versions, with the recently discovered vulnerabilities impacting only the latter.https://embeds.beehiiv.com/ea0ad200-e70f-457c-86ed-86d5e4db4bb8
Why SharePoint Vulnerabilities Matter Beyond the Platform
While this vulnerability doesn’t directly target cryptocurrencies or blockchain technology, the fact that a widely used enterprise platform like SharePoint was exploited to gain remote access and steal sensitive data raises important questions about the state of digital security, trust, and infrastructure.
SharePoint is a cornerstone for countless organizations worldwide, and when such critical systems are compromised, it spotlights vulnerabilities that can ripple across the broader tech landscape.
For ecosystems like Shiba Inu and other decentralized platforms, this serves as a powerful reminder that security is not just about the blockchain itself, but also about the surrounding infrastructure that supports users and applications.
Protecting these systems from unauthorized access and data breaches is crucial to maintaining trust among users and investors. As the crypto and Web3 spaces continue to mature, ensuring end-to-end security, from smart contracts to enterprise tools, will be key to fostering long-term growth and adoption.
This incident is a call to action for developers, companies, and communities alike to continuously strengthen their defenses and prioritize the integrity of the entire technological stack. After all, trust is the foundation upon which all digital innovation, including Shiba Inu’s expanding ecosystem, is built.
