The cybersecurity landscape has been dramatically reshaped by the advent of generative AI. Attackers now leverage large language models (LLMs) to impersonate trusted individuals and automate these social engineering tactics at scale.  Let's review the status of these rising attacks, what's fueling them, and how to actually prevent, not detect, them.  The Most Powerful Person on the Call Might Not Be Real Recent threat intelligence reports highlight the growing sophistication and prevalence of AI-driven attacks: Voice Phishing Surge: According to CrowdStrike's 2025 Global Threat Report , there was a 442% increase in voice phishing (vishing) attacks between the first and second halves of 2024, driven by AI-generated phishing and impersonation tactics. Social Engineering Prevalence: Verizon's 2025 Data Breach Investigations Report indicates that social engineering remains a top pattern in breaches, with phishing and pretexting accounting for a significant portion of inc...

AI agents are changing the way businesses work. They can answer questions, automate tasks, and create better user experiences. But with this power comes new risks — like data leaks, identity theft, and malicious misuse. If your company is exploring or already using AI agents, you need to ask:  Are they secure? AI agents work with sensitive data and make real-time decisions. If they're not protected, attackers can exploit them to steal information, spread misinformation, or take control of systems. Join Michelle Agroskin, Product Marketing Manager at Auth0 , for a free, expert-led webinar — Building AI Agents Securely  — that breaks down the most important AI security issues and what you can do about them.

Security Service Edge (SSE) platforms have become the go-to architecture for securing hybrid work and SaaS access. They promise centralized enforcement, simplified connectivity, and consistent policy control across users and devices. But there's a problem: they stop short of where the most sensitive user activity actually happens—the browser. This isn't a small omission. It's a structural limitation. And it's leaving organizations exposed in the one place they can't afford to be: the last mile of user interaction. A new report Reevaluating SSEs: A Technical Gap Analysis of Last-Mile Protection analyzing gaps in SSE implementations reveals where current architectures fall short—and why many organizations are reevaluating how they protect user interactions inside the browser. The findings point to a fundamental visibility challenge at the point of user action. SSEs deliver value for what they're designed to do—enforce network-level policies and route traffic securely between en...

The Evolving Healthcare Cybersecurity Landscape   Healthcare organizations face unprecedented cybersecurity challenges in 2025. With operational technology (OT) environments increasingly targeted and the convergence of IT and medical systems creating an expanded attack surface, traditional security approaches are proving inadequate. According to recent statistics, the healthcare sector experienced a record-breaking year for data breaches in 2024, with over 133 million patient records exposed. The average cost of a healthcare data breach has now reached $11 million, making it the most expensive industry for breaches.  What's changed dramatically is the focus of attackers. No longer content with merely extracting patient records, cybercriminals are now targeting the actual devices that deliver patient care. The stakes have never been higher, with ransomware now representing 71% of all attacks against healthcare organizations and causing an average downtime of 11 days per inc...

The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...

Everybody knows browser extensions are embedded into nearly every user's daily workflow, from spell checkers to GenAI tools.

This includes information and analysis on how many extensions have risky permissions, which kinds of permissions are given, if extension developers are to be trusted, and more. Below, we bring key statistics from the report. Highlights from the Enterprise Browse...

Attackers aren't waiting for patches anymore — they are breaking in before defenses are ready. Trusted security tools are being hijacked to deliver malware. Even after a breach is detected and patched, some attackers stay hidden. This week's events show a hard truth: it's not enough to react after an attack. You have to assume that any system you trust today could fail tomorrow. In a world where AI tools can be used against you and ransomware hits faster than ever, real protection means planning for things to go wrong — and still staying in control. Check out this week's update to find important threat news, helpful webinars, useful tools, and tips you can start using right away. ⚡ Threat of the Week Windows 0-Day Exploited for Ransomware Attacks — A security affecting the Windows Common Log File System (CLFS) was exploited as a zero-day in ransomware attacks aimed at a small number of targets, Microsoft revealed.

Today, every unpatched system, leaked password, and overlooked plugin is a doorway for attackers. Supply chains stretch deep into the code we trust, and malware hides not just in shady apps — but in job offers, hardware, and cloud services we rely on every day. Hackers don't need sophisticated exploits anymore. Sometimes, your credentials and a little social engineering are enough. This week, we trace how simple oversights turn into major breaches — and the silent threats most companies still underestimate. Let's dive in. ⚡ Threat of the Week UNC5221 Exploits New Ivanti Flaw to Drop Malware — The China-nexus cyber espionage group tracked as UNC5221 exploited a now-patched flaw in Ivanti Connect Secure, CVE-2025-22457 (CVSS score: 9.0), to deliver an in-memory dropper called TRAILBLAZE, a passive backdoor codenamed BRUSHFIRE, and the SPAWN malware suite. The vulnerability was originally patched by Ivanti on February 11, 2025, indicating that the threat actors studied the patch a...

The rules have changed. Again. Artificial intelligence is bringing powerful new tools to businesses. But it's also giving cybercriminals smarter ways to attack. They're moving quicker, targeting more precisely, and slipping past old defenses without being noticed. And here's the harsh truth: If your security strategy hasn't evolved with AI in mind, you're already behind. But you're not alone—and you're not powerless. Cybercriminals are now using AI not just to automate attacks but to customize them—tailoring phishing emails, cloning voices, manipulating data models, and probing systems for subtle weaknesses at a scale we've never seen before. These aren't future threats—they're happening now. So the real question is: Are you ready to defend against them? In our upcoming webinar, " AI Uncovered: Re-Shaping Security Strategies for Resilience in the Era of AI ," you'll hear from Diana Shtil, Senior Product Marketing Manager at Zscaler. She'll break down what's changing in cyb...

Most microsegmentation projects fail before they even get off the ground—too complex, too slow, too disruptive. But Andelyn Biosciences proved it doesn't have to be that way.  Microsegmentation: The Missing Piece in Zero Trust Security   Security teams today are under constant pressure to defend against increasingly sophisticated cyber threats. Perimeter-based defenses alone can no longer provide sufficient protection as attackers shift their focus to lateral movement within enterprise networks. With over 70% of successful breaches involving attackers moving laterally, organizations are rethinking how they secure internal traffic.  Microsegmentation has emerged as a key strategy in achieving Zero Trust security by restricting access to critical assets based on identity rather than network location. However, traditional microsegmentation approaches—often involving VLAN reconfigurations, agent deployments, or complex firewall rules—tend to be slow, operationally disrupt...
