Executive Summary BlueHammer (CVE-2026-33825) is an eight-stage local privilege-escalation chain targeting the Windows Defender Antimalware Platform before 4.18.26030.3011. It does not grant initial access; an attacker needs standard-user code execution first. Still, in the lab, it reached NT AUTHORITY\SYSTEM, recovered domain-admin credentials from LSASS, and moved laterally via pass-the-hash. This is not memory corruption. It chains CloudFilter callbacks, batch oplocks, object-manager…

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…
Last month, Volexity published two blog posts in its Mind the (Patch) Gap series. The series details Volexity’s discovery of multiple Chinese threat actors simultaneously using zero-day exploits in Google Chrome and Microsoft Windows in campaigns that, if successful, would download and run malware on an exploited system. Those posts covered technical details of the exploits and malware Volexity observed, along with general detection methods for each case. Behind those findings was one of the…
Microsoft has released its October 2026 Patch Tuesday security updates, addressing vulnerabilities across its products and services. As organizations continue to navigate an evolving threat landscape, applying security patches promptly remains critical to reducing exposure and strengthening security posture. This month’s updates highlight the importance of identifying affected assets, prioritizing remediation, and staying ahead of emerging risks. This Patch Tuesday is Microsoft’s largest…
Norway’s privacy regulator Datatilsynet has fined advertising technology company Xandr 92 million Norwegian kroner, approximately $9.6 million, for unlawfully processing and sharing sensitive information about Grindr users. While the decision concerns users in Norway, the data-sharing practices were not confined to Norwegian users. BleepingComputer reports that information about Grindr users in other countries was also exposed through the advertising system. Between July 2018 and April 2020,…

Most of what has been written about AI and vulnerability management focuses on speed: how much faster frontier AI models can scan code, find weaknesses, design patches, and build exploits than any human team. That part is true, and it matters to how we remediate vulnerabilities. The more challenging question is what happens after the scan? Frontier AI models are about to hand every security team a far larger set of findings than they have ever had to work through. The real test for chief…

In this article Why you should attend Microsoft IgniteMake the most of your time at Microsoft Ignite Explore the Security sessions at Microsoft Ignite 2026 Build your schedule In the agentic era, the stakes are higher: AI agents now act with real access to your identities, your data, and your cloud, so every adoption decision is a trust decision. That is why security is a through line at Microsoft Ignite 2026, from a Security Pre-Day before the event opens to a security segment in the keynote,…
How reliability scoring keeps risky patches out of zero-touch jobs, and how one blocking rule stops a paused update across your environment. Executive Summary Microsoft has paused the rollout of KB5002907, an optional Microsoft 365 Apps update that left some Office 2016 and Office 2019 installations unlicensed or removed. When an update runs into trouble after release, the teams that already deployed it are the ones left dealing with it, as KB5002907 and several other 2026 updates have shown.…
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…

You receive an invitation to a password-protected meeting, a secure chatroom, or a shared document. To get access, it says, you need to enter a short code on a sign-in page for one of your accounts. The message claims the code will let you open the document or join the meeting. In fact, it approves a sign-in the scammer started. The page is real and the code works, which is why this type of attack—known as device code phishing—is so dangerous. Device code phishing abuses a legitimate sign-in…
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 365 makes sharing files easy, but access can remain long after its original purpose has ended, leaving organizations with little visibility into who can still reach sensitive data. tenfold Software explains how centralized access governance and owner-driven reviews can help identify and remove unnecessary access.

AI has already made fundamental changes to the operating environment for cybersecurity. Cyberattackers are testing more paths, adapting their techniques, and moving across digital environments with greater speed and persistence. The weaknesses they exploit remain familiar: excessive permissions, unprotected authentication flows, unpatched systems, exposed execution paths, and gaps between controls. What has changed is how quickly these weaknesses can combine into attack paths that cross…
Every benchmark tells a story. The most valuable ones tell us where to improve next. For five consecutive quarters Microsoft has published email security benchmarking reports to provide greater transparency into real-world protection outcomes. The results have shown strong Microsoft Defender performance across pre-delivery and post-delivery scenarios, while revealing where threats and defenses continue to evolve. This quarter’s benchmark examines how continuous measurement informs protection…
Executive Summary Microsoft’s September 2026 security updates, KB5124008 and KB5124012, have been linked to USB audio failures on some Windows systems, highlighting the operational risk that can accompany security patching. Qualys TruRisk Eliminate classified both updates as Low Reliability, signaling the need for additional validation before production deployment. Patch Reliability helps IT and security teams focus on deeper testing where needed while allowing high-confidence patches to move…
Every wave of technology excitement creates a new opportunity for cyberattackers, and AI is no exception. Microsoft Threat Intelligence has published research showing a growing set of campaigns that impersonate popular AI platforms and tools, including ChatGPT, Microsoft Copilot, DeepSeek, and Claude.1 The goal is to make phishing, search-driven malware campaigns, and malvertising—which is malicious advertising that uses online ads to lure users to harmful sites, downloads, or redirect…
BlueMoon, a shared Chrome and Windows exploit kit, shows why “patch later” is becoming a dangerous gamble. Security updates are easy to put off. The browser still opens, Windows still works, and choosing to relaunch your browser or restart your computer later can feel harmless. But a newly documented exploit kit called “BlueMoon” shows how quickly patching delays can become dangerous. Proofpoint Researchers found four espionage groups using the same exploit chain against Chrome browsers running…
Microsoft’s September 2026 Patch Tuesday addresses 964 CVEs, including 104 rated Critical and 860 rated Important, making it the company’s largest Patch Tuesday release on record. Microsoft lists 974 CVEs in its full September security release. However, 10 of those affect cloud services or involve fixes that Microsoft applies itself, leaving 964 vulnerabilities that customers need to patch. The release includes fixes for two actively exploited Windows zero-days. Both are local elevation-of…
Your security data is the most important asset in your SOC. Not the dashboards, not the detections, not the AI features on the roadmap slide. The data. And most vendors make you pay, wait, or license your way to getting it back out. Every investigation your analysts run, every model you train, every agent you deploy is only as good as the telemetry underneath it. So here is the question I want you to ask every vendor in your stack: if I want my data, right now, what does that take?Most vendors…
Key Takeaways Modern AD attacks use legitimate protocols end-to-end, no malware, no exploit, nothing for signature tools to fingerprint. The evidence is already in the logs; what is missing is the narrative linking five benign-looking Windows events into a single attack. A full domain takeover can be completed in 54 minutes, from the first password spray to the forged Golden Ticket, with each individual event appearing normal. Detection catches the move; posture management explains why it was…
Scammers are becoming more strategic about where they target people. Nine in ten toll scams—the fake unpaid-toll messages that threaten fines or license suspension—arrive by email or text, while roughly six in ten romance scams show up first on social media. That’s no coincidence. Rather than blasting the same message everywhere, criminals are tailoring different scams to the platforms where they’re most likely to succeed. This finding comes from Malwarebytes’ own threat research systems and…
In this article What is the Cybersecurity Incident Response Readiness Workshop?Our approach: How we assess your maturityLearn more Cybersecurity incidents can unfold in hours, but response plans often fail at the point of execution: ownership is unclear, investigation findings is difficult to access, and critical decisions are delayed. That is why incident response cannot be something your organization figures out in real time. The Detection and Response Team (DART) – the Microsoft team that…
Microsoft has published details about a Windows malware campaign it calls TerminalFix. The social engineering used to infect people is very similar to what we’ve seen in ClickFix campaigns. A website visitor is presented with a fake Cloudflare CAPTCHA which, when clicked, secretly copies a malicious command to their clipboard. Then they receive instructions on what they need to do to “prove they are human,” when in reality they are being instructed to execute the malicious command. After…
Executive Summary ShieldBreak (CVE-2026-69414) is a zero-day elevation-of-privilege vulnerability in the Microsoft Malware Protection Engine used by Microsoft Defender, allowing a low-privilege local attacker to escalate to SYSTEM. A public PoC was released on August 12, 2026, and Microsoft assigned the CVE on August 14, and no patch is available yet. Qualys VMDR provides detection across Windows environments, and Qualys TruRisk Eliminate offers a mitigation that teams can apply now, with…
Security teams are overwhelmed with findings but still struggle to answer a simple question: which risks matter right now? A vulnerability alone is rarely the problem. The same vulnerability running in production, exposed through a misconfiguration or over-permissioned identity, is a real path to compromise. Organizations do not need longer lists of alerts. They need context that connects code, cloud resources, identities, and runtime activity so they can prioritize the issues that pose the…
Executive Summary CVE-2026-68820 is an actively exploited Windows vulnerability listed in CISA’s Known Exploited Vulnerabilities (KEV) Catalog, with a remediation deadline as suggested by CISA BOD 26-04. CISA BOD 26-04 introduces risk-based remediation timelines ranging from 3 to 14 days, increasing the pressure on teams to move quickly from patch availability to verified remediation. Installing the patch alone does not complete remediation, as the fix replaces a kernel driver and requires…

Security teams are being asked to defend a growing attack surface with fewer people and around the clock, against threat actors who never take a night off. As cyberattackers increasingly use AI to launch and scale campaigns, the volume, speed, and sophistication of threats continue to rise. Closing that gap takes more than tooling. It takes a partner that pairs a leading security platform with scaled intelligence and human experts who can act on your behalf at any hour. That’s exactly what…
As organizations adopt AI, they must secure both cloud and AI environments through a unified security control plane as their attack surface expands. Because modern applications and AI workloads are built and run in the cloud, security teams must understand which exposures matter most, prioritize what can truly be exploited, and reduce risk across cloud infrastructure, applications, identities, data, and AI systems in one place. Modern IT estates now span multiple clouds and on-premises systems,…
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…
