🚨 The NodeZero Rapid Response check for PHP2Shell is now available. CVE-2026-109618 and CVE-2026-109619 can allow unauthenticated remote code execution. Here’s what teams need to know and do. 🧵

AI models change how vulnerabilities are discovered. They don’t change how breaches happen. We’re joining @CrowdStrike’s Project QuiltWorks to bring the attacker’s perspective into the equation — connecting #NodeZero exploitability intelligence and proven attack-path evidence with Falcon® Next-Gen SIEM and Fusion SOAR. QuiltWorks accelerates discovery, NodeZero confirms actual exploitability, and CrowdStrike Falcon drives remediation and verification. Together, CrowdStrike and NodeZero deliver the complete cycle: Prove. Prioritize. Verify.

Please help us welcome Chad Keefer to Horizon3 as our new Vice President of Federal Sales! 🎉 Chad joins us with 24 years of federal go-to-market leadership experience, most recently as Head of U.S. Federal at Infoblox. Before his technology career, he served as a Platoon Leader in the United States Marine Corps, experience that shaped his approach to discipline, mission focus and team-building. In this role, he’ll be instrumental in building Horizon3’s federal sales organization and driving adoption of continuous security validation across civilian, defense and national security agencies.

Today, we’re proud to announce our $250M Series E funding round, co-led by @nightdragon and @NEA, at a $2B+ valuation. Six years ago, we invented the concept of AI Hackers, and we’ve spent every day since earning the right to autonomously pentest the most critical and sensitive networks in the world — with no humans in the loop. Cyberattacks now move at the speed of AI, and only the World’s Best AI Hacker™ is built for the moment. #AISecurity #ProactiveSecurity #infosec #cybersecurity

The @ecb just raised the bar for cyber resilience. Its latest guidance makes clear that AI-driven cyber threats are now an operational resilience issue—not just a security issue. The @bankofengland has also highlighted that frontier AI is increasing cyber and operational-resilience risk — signaling a broader supervisory expectation for firms to manage AI-enabled threats at greater speed and scale. Join former ECB Executive Board Member Yves Mersch and Horizon3.ai to discuss what the guidance means, what regulators are signaling, and how banks can build a credible, evidence-backed response before the 31 October deadline. 📅 July 30 👉 Register: events.horizon3.ai/decoding-… #CyberResilience #Banking #CyberSecurity #OperationalResilience #RiskManagement #AI

The ECB’s latest supervisory letter supports a shift we’ve been seeing in cybersecurity: AI isn't creating a new cyber risk. It's accelerating how quickly attackers exploit existing weaknesses. Significant institutions now have until October 31 to submit an AI cybersecurity Action Plan. Key questions to answer include: ✅ What can attackers actually exploit? ✅ What creates the greatest business risk? ✅ Did remediation eliminate meaningful risk? ✅ Is there proof that resilience is improving?

Between the hype, the panic, and the endless vulnerability noise, what does Mythos actually mean for your security operations? 👀 Hear from an expert panel on May 27 to get answers about the operational reality of AI-driven exploitation, not speculation. You'll learn: 👉 How AI is accelerating vulnerability discovery and weaponization 👉 Why vulnerability counts are becoming meaningless 👉 The shift from CVEs to validated attack paths and proven exposure 👉 What production-safe autonomous offensive security really looks like We know you feel stuck reacting to a constantly expanding, complex attack surface; come learn why AI is merely an amplifier of existing problems rather than their root cause.

We’ve said it before, and we’ll say it again: Attackers don’t break in. They log in. Yet only 40% of CISOs say credentials are their top risk. That’s a problem, because identity is how attacks scale: → lateral movement → privilege escalation → full domain takeover When one credential can hand over the keys to the kingdom, you’ve got to prioritize them. 🔗 Read The State of Assumed Security for more: horizon3.ai/downloads/resear… #AISecurity #ProactiveSecurity #infosec #cybersecurity

Right now, people are focusing on what Mythos can do. But the real story is what Mythos says about cybersecurity as a whole.
