Microsoft has disclosed that a privilege escalation and a denial-of-service flaw in Defender has come under active exploitation in the wild. The former, tracked as CVE-2026-41091, is rated 7.8 on the CVSS scoring system. Successful exploitation of the flaw could allow an attacker to gain SYSTEM privileges.

Consider a cached access key on a single Windows machine. It got there the way most cached credentials do - a user logged in, and the key stored itself automatically. Standard AWS behavior. No one misconfigured anything or violated a policy. Yet that single key, which was easily accessible to a minor-league attacker, could have opened a path to some 98% of entities in the company's cloud

Microsoft has identified an active supply chain attack targeting the @antv node package manager (npm) package ecosystem. A threat actor compromised an @antv maintainer account and published malicious versions of widely used data-visualization packages, resulting in cascading downstream impact. The compromise propagated through dependency chains into libraries like echarts-for-react (which has more than 1 million weekly downloads), expanding the blast radius into CI/CD pipelines and cloud workloads across the ecosystem. The malicious payload—a ~499 KB obfuscated JavaScript file—runs silently during npm install and is purpose-built to steal credentials from GitHub Actions environments. Key capabilities observed in the payload include multi-platform credential theft (GitHub, Amazon Web Services, HashiCorp Vault, npm, Kubernetes, 1Password), GitHub Action Runner process memory scraping, privilege escalation, dual-channel data exfiltration, and Supply chain Levels for Software Artifacts (SLSA) provenance forgery. These capabilities suggest a deliberate effort to evade analysis and an apparent focus on CI/CD environments. The authors of the antv account have also since confirmed in a ticket on the repo that the situation is now resolved. Attack chain overview Figure 1. @antv npm supply chain attack flow. The @antv organization maintains charting libraries (G2, G6) embedded across dashboards and applications. The attack proceeds through: Maintainer account compromise and publication of malicious @antv package versions Downstream dependency amplification ( echarts-for-react , size-sensor , and others) Automatic payload execution through a preinstall hook during npm install Execution chain: node → shell → bun → payload (Bun runtime installed if absent) Technical analysis The payload replaces the legitimate index.js with a single-line obfuscated script.

The Deputy CISO blog series is where Microsoft Deputy Chief Information Security Officers (CISOs) share their thoughts on what is most important in their respective domains. In this series, you will get practical advice, tactics to start (and stop) deploying, forward-looking commentary on where the industry is going, and more. In this article, Aaron Zollman, Vice President and Deputy CISO for Gaming at Microsoft discusses the unique challenges and rewards of securing gaming . There are more than 500 million monthly active players¹ across Xbox consoles, PC, handheld, and more through Xbox cloud gaming . They’re the folks who come to mind when people refer to “gaming culture.” But they’re not really the whole story. Globally, more than 3 billion people engage with gaming.² The majority of these people are gamers, but the number also includes developers working for independent gaming studios, engineers supporting the Xbox platform, and the security and operations professionals that support them all. In my role as Deputy CISO for Gaming at Microsoft, it’s this much larger, much more complex community that I have to take into account. My team and I aren’t tasked solely with protecting consoles or player accounts. We’re safeguarding intellectual property (IP), live operations, and the trust of billions of interactions. We’re also partnering on risks that range from cheating and monetization exploits to supply chain vulnerabilities and regulatory compliance for child safety and privacy. Gaming isn’t really a single culture, but rather a culture of cultures—each with their own risk factors to account for. At the heart of gaming is the player experience—their need for seamless access, low latency, and frictionless, immersive experiences. This goes hand-in-hand with privacy and safety in a world where cyberattackers could target well-known players. But aside from those basic needs, players form their own tribes, and a diverse, global player base requires a different approach—which makes securing gaming unique. You don’t approach it like you might traditional enterprise. Studios operate with creative autonomy, platforms demand global scale and low latency, and players expect frictionless experiences. That diversity makes gaming vibrant while also creating unique security challenges. Each culture comes with its own security risks Let’s first take a look at the risks that most often appear with each of the overlapping cultures that make up the world of gaming: Platforms , underpinning services like Xbox Game Pass and Xbox Cloud Gaming, require centralized infrastructure with high availability. Here, security must integrate seamlessly with identity systems and Microsoft-wide standards without slowing down gameplay. But platforms face a number of distinct risks. The complexity of platforms makes them a rich target for financially-motivated cyberattackers seeking to take over top accounts—or send targeted messages to individuals in an environment where they aren
