CISA is aware of malicious cyber activity targeting endpoint management systems of U.S. organizations based on the March 11, 2026 cyberattack against U.S.-based medical technology firm Stryker Corporation, which affected their Microsoft environment.1 To defend against similar malicious cyber activity, CISA urges organizations to harden endpoint management system configurations using the recommendations and resources provided in this alert. CISA is conducting enhanced coordination with federal partners, including the Federal Bureau of Investigation (FBI), to identify additional threats and determine mitigation actions. To defend against similar malicious activity that misuses legitimate endpoint management software, CISA urges organizations to implement Microsoft’s newly released best practices for securing Microsoft Intune; the principles of these recommendations can be applied to Intune and more broadly to other endpoint management software: Use principles of least privilege when designing administrative roles. Leverage Microsoft Intune’s role-based access control (RBAC) to assign the minimum permissions necessary to each role for completing day-to-day operations—permissions include what actions the role can take, and what users and devices it can apply that action to. Enforce phishing-resistant multi-factor authentication (MFA) and privileged access hygiene. Use Microsoft Entra ID capabilities (including Conditional Access, MFA, risk signals, and privileged access controls) to block unauthorized access to privileged actions in Microsoft Intune. Configure access policies to require Multi Admin Approval in Microsoft Intune. Set up policies that require a second administrative account’s approval to allow changes to sensitive or high-impact actions (such as device wiping), applications, scripts, RBAC, configurations, etc. Additionally, CISA recommends reviewing the following resources to strengthen defenses against similar malicious cyber activity: Microsoft resources: For recommendations on securing Microsoft Intune, see Best practices for securing Microsoft Intune. For guidance on implementing Multi Admin Approval in Microsoft Intune, see Use Access policies to implement Multi Admin Approval. For recommendations on configuring Microsoft Intune using zero trust principles, see Configure Microsoft Intune for increased security. For guidance on implementing Microsoft Intune RBAC policies, see Role-based access control (RBAC) with Microsoft Intune. For guidance on deploying Privileged Identity Management (PIM) across Microsoft Intune, Entra ID, and other Microsoft software, see Plan a Privileged Identity Management deployment. CISA resources: For guidance on implementing phishing-resistant multifactor authentication (MFA), see Implementing Phishing-Resistant MFA.

Maxime Rossi Bellom of Secmate reported these vulnerabilities to Siemens. General Recommendations Operators of critical power systems (e.g. TSOs or DSOs) worldwide are usually required by regulations to build resilience into the power grids by applying multi-level redundant secondary protection schemes. It is therefore recommended that the operators check whether appropriate resilient protection measures are in place. The risk of cyber incidents impacting the grid's reliability can thus be minimized by virtue of the grid design. Siemens strongly recommends applying the provided security updates using the corresponding tooling and documented procedures made available with the product. If supported by the product, an automated means to apply the security updates across multiple product instances may be used. Siemens strongly recommends prior validation of any security update before being applied, and supervision by trained staff of the update process in the target environment. As a general security measure Siemens strongly recommends to protect network access with appropriate mechanisms (e.g. firewalls, segmentation, VPN). It is advised to configure the environment according to our operational guidelines in order to run the devices in a protected IT environment. Recommended security guidelines can be found at: https://www.siemens.com/gridsecurity Additional Resources For further inquiries on security vulnerabilities in Siemens products and solutions, please contact the Siemens ProductCERT: https://www.siemens.com/cert/advisories Terms of Use The use of Siemens Security Advisories is subject to the terms and conditions listed on: https://www.siemens.com/productcert/terms-of-use. Legal Notice and Terms of Use This product is provided subject to this Notification (https://www.cisa.gov/notification) and this Privacy & Use policy (https://www.cisa.gov/privacy-policy). Recommended Practices CISA recommends users take defensive measures to minimize the exploitation risk of this vulnerability. Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolate them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most recent version available. Also recognize VPN is only as secure as its connected devices. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

Open EU Foundry status granted to innovative chiplet facility Anonymous (not verified) Mon, 03/16/2026 - 10:40 The Commission has granted the Open EU Foundry (OEF) status to Silicon Box in Novara, Italy. GettyImages © Nikola Ilic - E+ Under the European Chips Act, the OEF status is granted to new or upgraded innovative semiconductor manufacturing facilities. The status provides benefits to semiconductor facilities including administrative support, faster construction approvals and priority access to pilot lines under the Chips for Europe Initiative. This helps deepen European semiconductor supply chain resilience and boost innovation. Silicon Box’s project is a significant milestone in strengthening Europe’s semiconductor industry through its new advanced semiconductor packaging and testing facility. The facility will integrate multiple dies or chiplets - small, modular semiconductor blocks that perform specific functions - into a single package, effectively creating a multi-chip module that behaves like a single chip, using panel level packaging. Panel level packaging uses a more efficient large-panel approach to packaging, enabling higher output and lower cost compared to traditional methods in the final stage of the chip making process. The facility will also test chips at panel-level, grouping multiple chiplets into a single panel, enabling more comprehensive quality verification before final assembly. The project will provide an important base in Europe for developing innovative technologies, products and system solutions for the semiconductors key to powering AI, electric and autonomous vehicles, data centres, as well as supercomputing applications. The plant is expected to reach full capacity in 2033. This OEF status recognition follows four semiconductor projects across the EU which have previously been awarded OEF or IPF (integrated production facility) status in October 2025: ESMC in Germany (OEF) Ams-OSRAM in Austria (IPF) Infineon Technologies Dresden in Germany (IPF) STMicroelectronics in Italy The decision to grant OEF follows the Commission state aid decision concerning Silicon Box.

Among others, a marketplace for AI-based solutions for the agri-food sector will be introduced and funding will be devoted to capacity building in the development of agriculture specific foundation models (e.g., LLMs). AI is already reshaping agricultural production and can transform the way food is produced, benefiting the environment, climate and people. AI supports farmers, for instance through AI-driven advisory tools and handy applications that turn data into tailored recommendations. These help producers to make better and faster decisions accounting for local conditions, and increasing resource efficiency, e.g. saving water, and effectiveness. A new wave of opportunities is emerging, boosting precision farming, powering robots, and smartening machinery for field work. AI can also contribute to reducing reporting obligations and other administrative burdens. Climate & Environment AI has a long track record in environmental monitoring, forecasting, and Earth observation. It can enhance early-warning systems and aid disaster response as well as decision-making for resilience and climate preparedness. Ground-breaking initiatives such as Destination Earth provide high-resolution and interactive simulations with unprecedented predictive power through AI-driven applications.
