Transitioning from armed forces can feel like stepping into unfamiliar terrain. Nowhere is this perception stronger than in cybersecurity. The good news: Many of the skills veterans have already developed translate directly to cybersecurity roles.

Start Here: Strong Monitoring, Behavior-Based Controls, Virtual Patching
Thanks to Anthropic's Mythos presaging a world in which zero-day exploits are common, one cybersecurity expert says the new mantra is this: "assume you are unpatched." Vendors and customers must focus more than ever on strong monitoring, behavior-based controls and virtual patching.

Experts Warn of Faster and Higher Volume Attacks, Rising Patient Safety Worries
Emerging powerful AI tools - such as Anthropic's new Claude Mythos - that are capable of autonomously identifying and exploiting software bugs in a flash could reshape the healthcare cyber landscape by accelerating attacks and raising the risk of widespread operational disruption, experts said.

Project Glasswing Strengthens Key Platforms, Leaves Broad Exposure Untouched
Project Glasswing is giving select cybersecurity giants early access to Anthropic’s Claude Mythos Preview, boosting investor confidence in leaders Palo Alto Networks and CrowdStrike while raising concerns that smaller vendors, vulnerability firms and the broader internet will fall further behind.

Defense of Democracies' Mark Montgomery on Warfare Trends, Geopolitical Threats
Cyber operations now support military strategy rather than just acting alone. Mark Montgomery of the Foundation for Defense of Democracies warns that as militaries integrate cyber and kinetic action, private sector enterprises are facing greater exposure to geopolitical threats.

Okta's Brett Winterford on Identity Threats and Agentic AI Risks
AI is accelerating cyberattacks, collapsing timelines and exposing new identity risks. Okta's Brett Winterford explains how attackers are using AI to scale phishing, exploit credentials and infiltrate enterprises - and what CIOs must do to defend against this rapidly evolving threat landscape.

Also: How AI May Democratize Cybercrime and How Everyday Routers Enable Espionage
In this week's ISMG panel, four ISMG editors discussed big shifts in cybersecurity: Anthropic's "dangerous" new AI model that can uncover thousands of zero-days, growing concerns about a surge in AI-driven flaws, and the FBI disrupting a Russian espionage campaign targeting everyday routers.

Pure Play OT Security Firms Want A Seat At The Table
There's growing concern in the operational technology cybersecurity community that manufacturers and operators, and their security vendors, will be left out in the cold by the latest efforts to use artificial intelligence in securing critical software.

Why OT Security Comes Down to Risk Tolerance, Not Perfect Defense
Securing OT networks isn't about eliminating risk. It's about managing it strategically. Learn how a three-pillar framework of risk assessment, tolerance and acceptance, paired with a phased approach to microsegmentation, can turn an overwhelming challenge into a manageable journey.

Signature Healthcare EHRs, Patient Portal Offline; Some Cancer Care Cancelled
A Massachusetts healthcare system is diverting ambulance patients and is operating under downtime procedures as it deals with a cyberattack. The organization has also canceled certain cancer treatments, taken its patient portal offline and is unable to fill prescriptions at its retail pharmacies.

James Foster Points to Agentic Security and Need for Customers to Outsource Defense
