Safe Mode Podcast

In this episode of Safe Mode, host Greg Otto sits down with Chris Sestito, CEO of HiddenLayer Technologies, to discuss the evolving landscape of AI security and where current protection strategies are falling short. Sestito shares insights on how leading enterprises are rethinking their approach to AI asset protection, reveals real-world examples where traditional security measures failed against AI-specific threats, and explains the unique vulnerabilities that conventional cybersecurity tools struggle to address. The conversation explores the tension between rapid AI innovation and regulatory frameworks, with Sestito offering his perspective on what smarter, more adaptive AI regulation should look like and how policymakers can balance innovation with robust security protections. Don't miss this deep dive into the future of AI security, insider threats in AI-driven workplaces, and Sestito's top recommendations for government regulators crafting new AI security laws In our reporter chat, Greg talks with Tim Starks about what the federal government is doing to meet the demands put forth in President Trump’s cybersecurity executive order.

On this episode of Safe Mode, Greg Otto sits with two CISA leaders, Chris Butera, Acting Executive Assistant Director for CISA’s Cybersecurity Division, and Bob Costello, CIO of CISA, at the 2025 Black Hat USA Conference to discuss numerous different topics: the recent Microsoft Sharepoint vulnerability, the upcoming CIRCIA rulemaking, the future of the JCDC, state and local cyber grants, and the emphasis they are placing to strengthening public-private partnerships. In our reporter chat, Greg talks with Matt Kapko about what they both heard during their conversations at the Black Hat conference.

On this episode of Safe Mode, host Greg Otto sits down with Daria Bahrami, Head of Policy at Dreadnode, for an in-depth exploration of the new AI Action Plan and its sweeping implications for critical infrastructure security. From the technical hurdles in securing vital systems to the growing need for “secure-by-design” technology standards, Daria breaks down what’s at stake as artificial intelligence becomes both a linchpin and a potential liability in our national cyber defenses. In our reporter chat, Greg talks with Tim Starks about the motion on Capitol Hill to confirm CISA Director nominee Sean Plankey.

In this episode of Safe Mode, Greg talks with Tom Pace, CEO of Netrise, about the recent Salt Typhoon cyberattack against U.S. telecom networks and how the government is responding. Tom explains why it’s so hard to fully protect or fix these giant, complex systems, even when officials say they have stopped the threat. He points out the tough choices telecom companies face—like keeping service running, following regulations, and fixing security gaps—which don’t always work together. The conversation also covers problems with current rules and why spending more money isn’t always the answer. Listen for a straightforward discussion about what it will really take to keep our communication networks safe.

Greg is joined in studio with Kemba Walden and Devin Lynch from the Paladin Global Institute about securing the future of AI. They break down the multilayered AI technology stack and highlight where systems are most at risk—from data poisoning to adversarial model extraction. We discuss the adequacy of today’s security standards, the evolving responsibilities of cloud providers, and the ethical challenges facing policymakers in an era of rapid AI adoption. Tune in for practical insights on best practices, global cooperation, and the next wave of threats and opportunities as AI shapes critical infrastructure worldwide.

Michael Saintcross, Senior Director for Defense and Intelligence Community Business at Optiv + ClearShark, joins SNG host Wyatt Kash in a sponsored podcast discussion on why agencies must pivot from traditional ICAM strategies to solutions that offer granular control and "zero standing privilege" to defuse advanced threats. This segment was sponsored by Optiv + ClearShark.

This week, Greg talks to Will Dixon, Senior Intelligence Collection Manager for Intel471, about the lifecycle and takedown of DanaBot — one of the most notorious malware-as-a-service (MaaS) platforms of the last decade. We'll explore how DanaBot transformed from a banking trojan into a full-featured MaaS tool, capable of serving both criminal enterprises and espionage operations. Will shares insights on its technical evolution, how it became a vital cog in the Initial Access Broker (IAB) ecosystem, and the anti-forensic tricks that kept detection teams on their toes. We'll also dig into the broader impact on the cybercrime underground: How did DanaBot’s productization and subscription model reshape the MaaS and IAB economies? Has its downfall changed how actors maintain operational security, or blurred the lines between crimeware and espionage tools? This episode is perfect for anyone interested in the inside story of a leading-edge cybercrime operation and global enforcement campaign.

Greg Otto talks with Andrew Carney, project manager at DARPA, about the AIxCC competition. With the finals set to be held in August during DEF CON, they discuss how these autonomous systems fared in detecting and remediating vulnerabilities, as well as the key lessons learned from live exercises and the semifinals. The conversation highlights DARPA's vision to merge formal software engineering with large language models to dramatically reduce software vulnerabilities and explains the scientific and engineering advances still needed to achieve this goal at scale. We also examine the challenges of safeguarding critical infrastructure, particularly when so much depends on open-source projects maintained by volunteers, and consider the impact of AI on patch deployment, code verification, and sustainable defense. In the reporter chat, Greg talks with Matt Kapko about a story debunking the 16 billion password hack.

Greg Otto talks with RSA CEO Rohit Ghai on the global shift toward passkeys and passwordless authentication. Together, they explore pressing issues including the differences between consumer and enterprise solutions, infrastructure vulnerabilities, regulatory challenges, and how emerging threats are evolving as passwordless adoption accelerates. The discussion also covers the complexities practitioners face as they navigate credential transitions in a rapidly changing security landscape. In the reporter chat, Greg talks with Matt Kapko about the attack on a top grocery distributor in the United States.

Greg Otto talks with Eran Barak, CEO and co-founder of MIND, on the dramatic rise of insider threats in cybersecurity, exploring recent high-profile cases and the factors fueling this surge. He discusses which industries and data types are most at risk, how insider tactics have evolved, and practical strategies for organizations to detect and prevent internal threats. In our reporter chat, Greg talks with Derek Johnson on how vibe coding can be secure as it grows into a practice that software developers rely on for their work.
