Apple teases M5 MacBook

1 Share

Apple is teasing the imminent launch of a new MacBook with an M5 chip. In an X post, Apple SVP of worldwide marketing Greg Joswiak wrote that “something powerful is coming,” and a short video in the post includes the words “coming soon” and a silhouette of an Apple laptop. Joswiak’s post also includes the word “Mmmmm” — five Ms, get it? — and the laptop silhouette is in the shape of a Roman numeral V.

This new laptop isn’t a big surprise, as Bloomberg’s Mark Gurman recently reported that Apple is set to announce a base-model MacBook Pro with an M5 chip this week. The imminent launch of M5-equipped products from Apple isn’t a shock, either: iPad Pros with an M5 chip have also already been unboxed on YouTube, and Gurman said that the new tablets are set to be announced this week, though Joswiak hasn’t hinted at that just yet. Gurman also said that a Vision Pro with “a faster chip” is set to be announced this week, which could be the new headset recently spotted in an FCC filing.

Microsoft raises the bar: A smarter way to measure AI for cybersecurity

1 Share

ExCyTIn-Bench is Microsoft’s newest open-source benchmarking tool designed to evaluate how well AI systems perform real-world cybersecurity investigations.1 It helps business leaders assess language models by simulating realistic cyberthreat scenarios and providing clear, actionable insights into how those tools reason through complex problems. In contrast to previous benchmarks that concentrated on threat intelligence trivia or static knowledge, this benchmark evaluates AI agents in multistep, data-rich, multistage cyberattack scenarios within a simulated security operations center (SOC) in Microsoft Azure. It incorporates 57 log tables from Microsoft Sentinel and related services to reflect the scale, noise, and complexity of real incidents and SOC operations.2

Why ExCyTIn-Bench matters for business

For chief information security officers (CISOs), IT leaders, and buyers, ExCyTIn-Bench offers a clear, objective way to assess AI capabilities for security. It’s not just about accuracy in cyberthreat reports, trivia, or toy simulations, but about how well AI can investigate, adapt, and explain its findings in the face of real-world cyberthreats. As cyberattacks grow in sophistication, tools like ExCyTIn-Bench help organizations select solutions that truly enhance detection, response, and resilience.

Microsoft uses this framework internally to strengthen its AI-powered security features and test their ability to withstand real-world cyberattacks. Our security-focused in-house models rely on feedback from ExCyTIn to uncover weaknesses in detection logic, tool capabilities, and data navigation. For broader integration, we are also collaborating with security products such as Microsoft Security Copilot, Microsoft Sentinel, and Microsoft Defender to evaluate and provide feedback on their AI features. Additionally, Microsoft Security product owners can monitor how different models perform and what they cost, allowing them to choose appropriate models for specific features.

How ExCyTIn-Bench improves upon traditional benchmarks

Unlike traditional benchmarks3,4 that rely on multiple choice questions—which are often susceptible to guesswork—ExCyTIn-Bench adopts an innovative, principled methodology for generating questions and answers from threat investigation graphs. Human analysts conceptualize threat investigations using incident graphs, specifically bipartite alert-entity graphs.5 These serve as ground truth, supporting the creation of explainable question-answer pairs grounded in authentic security data. This enables rigorous analysis of strategy quality, not just final answers. Even recent industry publications, such as CyberSOCEval,3 focus on packaging realistic SOC scenarios and evaluating how models investigate static evidence in them. ExCyTIn adopts a different approach in both design and technical implementation by positioning the agent within a controlled Azure SOC environment: where the agent queries live log tables, transitions across data sources, and plans multistep investigations.

As a result, ExCyTIn evaluates comprehensive reasoning processes, including goal decomposition, tool usage, and evidence synthesis, under constraints that simulate an analyst’s workflow. By defining rigorous ground truths and extensible frameworks, ExCyTIn-Bench enables realistic, multiturn, agent-based experimentation, collaboration, and continuous self-improvement, all reinforced by verifiable, fine-grained reward mechanisms for AI-powered cyber defense.6

ExCyTIn-Bench innovations that deliver strategic value

  • Realistic security evaluation. Unlike most open-source benchmarks,3,4 ExCyTIn-Bench captures the complexity and ambiguity of actual cyber investigations. AI agents are challenged to analyze noisy, multitable security data, construct advanced queries, and uncover indicators of compromise (IoCs)—mirroring the work of human SOC analysts.
  • Transparent, actionable metrics. The benchmark provides fine-grained, step-by-step reward signals for each investigative action over basic binary success and failure metrics found in current benchmarks. This transparency helps organizations understand not just what a model can do, but how it arrives at its conclusions—critical for actionability, trust, and compliance.
  • Accelerating innovation. ExCyTIn-Bench is open-source and designed for collaboration. Researchers and vendors worldwide can use it to test, compare, and improve new models, driving rapid progress in automated cyber defense.
  • Personalized benchmarks (coming soon). Create tailored cyberthreat investigation benchmarks specific to the threats occurring in each customer tenant.

Latest results—language models are getting smarter

Recent evaluations show that the newest models are making significant strides:

Table comparing average rewards of different AI models across several incidents. GPT-5 (Reasoning=High) shows the highest average reward.
  • GPT-5 (High Reasoning) leads with a 56.2% average reward, outperforming previous models and demonstrating the value of advanced reasoning for security tasks.
  • Smaller models with effective chain-of-thought (CoT) reasoning—like GPT-5-mini—are now rivaling larger models, offering strong performance at lower cost.
  • Explicit reasoning matters—Lower reasoning settings in GPT-5 drop performance by nearly 19%, highlighting that deep, step-by-step reasoning is essential for complex investigations.
  • Open-source models are closing the gap with proprietary solutions, making high-quality security automation more accessible.
  • New models are getting close to top CoT techniques (ReAct, reflection and BoN at 56.3%) but don’t surpass them, suggesting comparable reasoning during inference.

Now Available by Popular Demand: GitHub Copilot in SSMS (Preview)

1 Share

Last month we shared that we made the decision to pivot to GitHub Copilot for the SQL Server Management Studio (SSMS) copilot integration.  This month we’re happy to announce that GitHub Copilot in SSMS is now available in Preview 3 of SSMS 22! If you’re looking to get help writing, editing, or fixing T-SQL, have questions to ask about your database, and you’d like to use your GitHub Copilot subscription, then it’s time to install SSMS 22 Preview 3 with the AI Assistance workload.

With GitHub Copilot in SSMS you can login using your existing GitHub Copilot subscription, and if you don’t have one, you can sign up for Copilot Free right from the chat window in SSMS. Once you’re logged in, open a query editor and connect to a database, and you’re off and running! 

Using GitHub Copilot in SSMS

GitHub Copilot in SSMS has database and connection context when you’re connected in an editor window, so it knows the version of SQL to which you’re connected and has knowledge of the database schema.  From the chat window you can get assistance with T-SQL in the active editor or ask questions about your database.  Switch to another editor window to chat with a different database, or start a new thread if you want to maintain separate conversations. You can find demos of GitHub Copilot in SSMS in action in our new playlist.

When typing in the editor you’ll notice that there is no auto-complete functionality; that’s expected, but it’s temporary!  We prioritized making this first preview release available to our users, and we are actively working to bring parity with the original Copilot in SSMS, in addition to new capabilities unlocked by GitHub Copilot.  This will take a few releases, so review the list of current limitations to understand what’s available in this initial release. Remember this is preview, which means we are far from finished!  It also means that this your chance to provide feedback on what you like so far, and what you would like to see – we’d love to hear from you on the feedback site (please make sure to search first before creating an item).

A few FAQs below, as a reminder…

Will you backport GitHub Copilot to SSMS 21?

No, GitHub Copilot in SSMS will only be available in SSMS 22.

Do I need a GitHub Copilot subscription to use GitHub Copilot in SSMS?

Yes.

What if I don’t have a GitHub Copilot subscription?

You can sign up for a personal subscription (GitHub Copilot · Your AI pair programmer), or your company can sign up for a business or enterprise subscription.  Once you have a subscription, you can use GitHub Copilot in SSMS.

What GitHub Copilot subscriptions are supported?

All personal and business subscriptions are supported.

Can I use GitHub Copilot for free?

Yes! GitHub Copilot offers a free, personal subscription that can be used in SSMS, just like it can be used in Visual Studio and VS Code.

What’s next?

Our teams are thrilled to make GitHub Copilot in SSMS (Preview) available to users, and we look forward to your feedback.  We will evolve this integration in subsequent releases of SSMS 22 Preview, with the ultimate goal of making it easier for users to leverage AI assistance in SSMS and become more efficient in their daily workflow.

End of Windows 10 Support: What Defender Customers Need to Know

1 Share

As of today, October 14, 2025, Microsoft is officially ending support for Windows 10. This means that Windows 10 devices will no longer receive security or feature updates, nor technical support from Microsoft. While these devices will continue to operate, the lack of regular security updates increases vulnerability to cyber threats, including malware and viruses. Applications running on Windows 10 may also lose support as the platform stops receiving updates.

Will Defender continue to protect Windows 10 devices?

  • Defender supports a range of legacy systems, including Windows 10. (See here for a full list of supported operating systems.) Microsoft Defender will continue to provide detection and protection capabilities to the extent possible on Windows 10 and other legacy systems. Keep in mind that security solutions on legacy systems are inherently less secure and may not be able to receive all new features, so please review the next section for important actions you can take.
  • For Windows 10 customers without Defender, Microsoft will continue to provide security intelligence updates for the built-in Microsoft Defender Antivirus protection through October 2028. Of course, Defender Antivirus alone isn't a comprehensive risk mitigation posture without Microsoft Defender detection and response deployed across your digital estate.

What should customers do to protect their Windows 10 devices?

  • Upgrade to Windows 11:
    Moving to Windows 11 is strongly recommended for PCs eligible to upgrade. Windows 11 delivers the latest security features, improved performance, and ongoing support at no additional cost. This is the best way to ensure your endpoints remain protected and compliant. Devices running Windows 10 will be more vulnerable, even with ongoing security intelligence updates (SIUs).
  • Extended security update (ESU) program:
    If upgrading isn’t immediately possible, Microsoft offers an ESU program for Windows 10. The ESU program provides critical and important security updates but does not include new Windows features or technical support.
    • Enterprise customers can purchase ESU for up to three years or receive it at no additional cost with a Windows 365 subscription.
    • Cloud and virtual environments: Windows 10 devices accessing Windows 11 Cloud PCs via Windows 365 or Virtual Machines are entitled to ESU at no extra cost, with automatic updates.
    • Consumer customers have options to enroll for one year of ESU, including free enrollment methods in certain regions.

For further guidance, check out the posts below or connect with your Microsoft account team.
