Une vulnérabilité a été découverte dans Stormshield Management Center. Elle permet à un attaquant de provoquer une exécution de code arbitraire à distance.
Microsoft has released out-of-band (OOB) Windows updates to remove trust in certificates tied to compromised eMudhra certificate authority keys, protecting systems that do not receive automatic certificate trust updates. [...]
Microsoft is building a way for EDR products to run outside the Windows kernel. It is called the Windows Endpoint Security Platform, and two of its binaries already ship in Windows Insider build. One is the kernel driver wesp.sys, the other the user-mode API espclient.dll. Microsoft wants one kernel driver it maintains itself, in place of the one every security vendor currently ships, after the July 2024 CrowdStrike update crashed 8.5 million machines. WESP is undocumented, but the binaries…
Build identity resilience with Identity Posture Assessment, an on-demand Microsoft 365 report that scores your identity defenses and shows how fast you can fix the gaps.
Attackers may be in your tenant before you connect it. Huntress Managed ITDR Lookback reviews 180 days of Microsoft 365 logins & our SOC acts on active incidents.
Agents are rapidly becoming part of how work gets done. They can support a range of activities from writing code and researching products to analyzing revenue, processing expenses, and acting across the systems that run the business. To be most useful, they often need access to company data, applications, tools, and other agents. That access is what makes agents more capable. With that capability can come insider risk. This does not mean agents are inherently malicious. It means they are…
Starting with Windows updates released on and after October 13, 2026, Microsoft is making hardening changes to the [Resilient File System (ReFS)](https://learn.microsoft.com/windows-server/storage/refs/refs-overview). This change is not enable by default until 2027. Please see [Hardening changes for ReFS volumes on removable media](https://support.microsoft.com/en-us/servicing/os/windows/docs/2026/10/hardening-changes-for-refs-volumes-on-removable-media) for more information.

AI agents are now running on employee devices, cloud platforms, and across developer workflows. Security teams need to see those agents, govern what they can reach, and contain them when something goes wrong. This month’s updates help you discover and control local AI agents, extend Zero Trust to agent traffic, and strengthen the security operations center (SOC) foundations that AI-era operations depend on. Here’s what’s new: Extend protection and support investigations with Microsoft Defender…
Managed ISPM now offers two deployment modes. Choose fully automated hardening or full control over which Microsoft 365 controls roll out, and when. See how it works.
The physics of cybersecurity are changing. So must the security operations center (SOC). Cyberattackers are using agents to automate execution at unprecedented scale. What once required entire teams now requires a single operator and an agent framework. That shift has exposed a hard truth: security cannot operate at AI speed when protection and operations are built as separate systems. Every handoff, integration, and boundary slows defenders down. Agents inherit that complexity. For agentic…
Microsoft has reminded admins to migrate Entra ID users to phishing-resistant authentication methods to avoid sign-in disruptions after it retires SMS first-factor sign-in starting in February 2027. [...]
Microsoft Teams will soon let administrators tweak the list of file extensions commonly associated with security threats to meet their company's security requirements. [...]
Microsoft has resolved a known issue that causes incorrect alerts warning that Defender Antivirus was turned off after installing recent updates. [...]
Microsoft has confirmed that mouse settings are being reverted on Windows 11 systems after installing the KB5120998 August 2026 non-security preview update. [...]
Microsoft released the KB5120998 preview cumulative update for Windows 11 versions 25H2 and 24H2, which comes with 35 changes, including improvements to the Start menu, taskbar, and Windows search. [...]
As organizations incorporate AI agents into more processes across business and operations, security teams can benefit from greater visibility and new purpose-built tools that help manage, secure, and govern AI. This month’s updates provide new capabilities to help organizations gain insights into agent activity, expand security coverage across supported environments, and enhance security management across their environments. Here’s what’s new: Extend expert-led protection with new capabilities…
The calculus of cybersecurity has changed. AI is reshaping how organizations build, deploy, operate, and defend digital systems. AI-powered development tools, agents, and autonomous workflows are accelerating innovation but they are also introducing new attack surfaces, new trust boundaries, and new security challenges. Microsoft has long helped organizations secure their digital estates using Zero Trust principles. That leadership was recently recognized by KuppingerCole analysts, which named…
Every organization needs security that protects end to end with the speed and scale of AI. Microsoft’s vision is simple: security should be ambient and autonomous, just like the AI it protects. As organizations scale AI and expand across environments, security teams need protection that covers every surface. This month’s updates help security and IT teams secure their AI environments, use AI to defend at speed and scale, and strengthen the foundations that AI-powered operations depend on.…
Elastic automatically translates your Microsoft Sentinel detection rules into Elastic Security. Export your Scheduled and Near Real Time (NRT) analytics rules from Sentinel, upload them, and Elastic picks up the mapping and translation from there using an LLM you choose. Watchlists and severity mappings carry over. This is the first automatic migration path off a modern SIEM, available now in Tech Preview in 9.5, and it works across multiple cloud providers and regions so you can deploy closer…

AAD Graph Activity Logs are now ingestible into Elastic and usable for threat detection within the SIEM/XDR solution. That sentence shouldn't be exciting, but it is. For most of the past decade, this slice of telemetry simply didn't exist as a customer-accessible log stream. Microsoft Graph Activity Logs (the modern graph.microsoft.com surface) went GA in April 2024. The legacy graph.windows.net surface, the one adversary tooling actually hits, stayed dark until early 2026. This post walks the…
Preamble In 2025 and 2026, we watched a pattern play out across the industry. Attackers stopped going after production servers directly and started targeting the automation that deploys to them. Compromised developer credentials, a modified workflow file, and suddenly every secret in a CI/CD environment is streaming to an attacker-controlled endpoint. We saw this play out across incidents involving major open-source projects, Fortune 500 companies, and critical infrastructure tooling. The…
