During his keynote at SecTor 2025, HD Moore, founder and CEO of runZero and widely recognized for creating Metasploit, invites the cybersecurity community to rethink the foundational “rules” we continue to follow—often without question. In conversation with Sean Martin and Marco Ciappelli for ITSPmagazine’s on-location event coverage, Moore breaks down where our security doctrines came from, why some became obsolete, and which ones still hold water.

One standout example? The rule to “change your passwords every 30 days.” Moore explains how this outdated guidance—rooted in assumptions from the early 2000s when password sharing was rampant—led to predictable patterns and frustrated users. Today, the advice has flipped: focus on strong, unique passwords per service, stored securely via password managers.

But this keynote isn’t just about passwords. Moore uses this lens to explore how many security “truths” were formed in response to technical limitations or outdated behaviors—things like shared network trust, brittle segmentation, and fragile authentication models. As technology matures, so too should the rules. Enter passkeys, hardware tokens, and enclave-based authentication. These aren’t just new tools—they’re a fundamental shift in where and how we anchor trust.

Moore also calls out an uncomfortable truth: the very products we rely on to protect our systems—firewalls, endpoint managers, and security appliances—are now among the top vectors for breach, per Mandiant’s latest report. That revelation struck a chord with conference attendees, who appreciated Moore’s willingness to speak plainly about systemic security debt.

He also discusses the inescapable vulnerabilities in AI agent flows, likening prompt injection attacks to the early days of cross-site scripting. The tech itself invites risk, he warns, and we’ll need new frameworks—not just tweaks to old ones—to manage what comes next.

This conversation is a must-listen for anyone questioning whether our security playbooks are still fit for purpose—or simply carried forward by habit.
