At #Pwn2Own Berlin, we saw a full VM escape on #ESXi. No official CVE yet. No patch yet. But the exploit works. This is the reality of #hypervisor risk: the most impactful vulnerabilities don’t wait for disclosure cycles. They exist in the gap between discovery and patching—and that gap is where defenders have the least control. ICYMI, we wrote up what happened, why VM escapes are different, and how to think about protecting that layer before fixes are available: hubs.li/Q04kkdnZ0 #CyberSecurity #VMware #Virtualization #HypervisorSecurity #ThreatResearch #ZeroDay #VMsecurity

As attacks on ESXi and other virtualization layers continue to rise, it is clear that traditional VPNs and workload-only Zero Trust are not enough. Our latest blog breaks down why Zero Trust Network Access (ZTNA) matters in the fight against ransomware and APTs targeting hypervisor management planes, and why identity-based segmentation and context-aware access are critical to closing the gaps attackers exploit. Read how extending Zero Trust to the virtualization layer with runtime preemption can help organizations better protect the infrastructure everything else depends on.

Hey Minneapolis — we’re live at VMUG Connect! Vali Cyber has boots on the ground and we’re ready to talk all things #hypervisor security, #ransomware protection, and preemptive defense for virtualized environments. If you’re attending, make sure to stop by our booth tomorrow to meet the team and chat about how organizations are reducing risk at the hypervisor layer before attacks can spread. And don’t miss our session, where we’ll be diving into the evolving threat landscape and why securing virtual infrastructure has become a critical part of modern cyber defense. Come say hi! #VMUGConnect #VMware #CyberSecurity #HypervisorSecurity #RansomwareProtection #VirtualInfrastructure

Advanced #security teams are starting to look beyond the #endpoint. On April 16 at 1pm ET, we’re hosting our first live #BrightTALK webinar on why #EDR struggles in virtualized environments—and what teams are doing instead at the #hypervisor. Join us to dig into identity‑led intrusions, credential abuse, and preemptive security before impact. 👉 Register here: hubs.li/Q04945wV0 #cybersecurity #preemptivesecurity #hypervisorsecurity #webinar

#MFA is everywhere — email, VPNs, #SaaS. But one place it matters just as much often gets overlooked: the #hypervisor. In our latest blog: - Why MFA is critical for hypervisor #security - How it disrupts modern #ransomware playbooks - How ZeroLock builds MFA into the hypervisor layer, alongside exploit blocking and #AI detection 👉 Read more: hubs.li/Q03MRJG80 #cybersecurity #hypervisorsecurity #VMware #infosec

🚩 Scattered Spider APT Hijacks VMware ESXi to Deploy Ransomware at Scale thehackernews.com/2025/07/sc… Threat actors known as Scattered Spider (UNC3944, also Octo Tempest and 0ktapus) are targeting VMware ESXi hypervisors across the U.S. retail, airline, transportation, and insurance sectors. They begin with voice phishing to IT help desks to reset AD passwords, then escalate to vCenter and ESXi control, enabling ransomware deployment directly from the hypervisor, and evading traditional endpoint defenses. #ScatteredSpider #HypervisorSecurity #Ransomware #CyberSecurity

🚨 Scattered Spider isn't your average ransomware gang. They're young, fast, and coordinated—and they're going straight for the core of your infrastructure: #VMware #ESXi. From MGM to Marks & Spencer, this group has caused hundreds of millions in damages by bypassing identity defenses and encrypting #hypervisors at scale. Our latest article on @cloudsa breaks down: 🔍 How Scattered Spider operates 🧠 Why ESXi is now a top target 🛡️ What your security team must do to respond Read it here: cloudsecurityalliance.org/bl… #hypervisorsecurity #virtualization #infosec #ScatteredSpider #ransomware

We’re just 2 weeks away from #VMUG Denver UserCon on May 29 at TopGolf Centennial, and you won’t want to miss it! @NM_lobster will be breaking down real-world #ESXi attacks during his speaking session, giving you valuable insights into the evolving threat landscape. Plus, he’ll show you how #ZeroLock protects hypervisors with: • Lockdown rules & virtual patching • Application filtering • SSH-MFA • AI-powered behavioral detection Don’t miss this chance to learn about the only #hypervisor #ransomware protection built to secure your virtual environment at the hypervisor layer.

Most #cybersecurity tools protect what’s on the hypervisor—but not the #hypervisor itself. Here’s the truth: you can’t protect what you can’t see. Hypervisors manage critical resources in real time, but traditional tools lack the visibility to monitor this crucial layer. The result? A major gap in #security coverage that attackers are ready to exploit. This is where #ZeroLock comes in: a runtime security solution built specifically for hypervisors. ZeroLock closes that gap with continuous monitoring and #AI behavioral analysis to keep your virtual environment safe from threats. Ready to bridge the gap? Contact us today at hubs.li/Q036tJK-0 to learn more. #hypervisorsecurity #virtualization #infosec
