Decipher Security Podcast

Christine Gadsby of BlackBerry, a longtime security executive, joins Dennis to talk about her extensive experience in cybersecurity, the evolution of security practices, the challenges of securing mobile communications, and the impact of AI on the security industry.

Ken Bagnall, founder and CEO of Silent Push, talks about the August National Security Presidential Memorandum (NSPM) on transnational cyber-enabled crime, how organizations can make “real impact” with cybercriminal disruption, and the challenges of measuring success in disrupting the cybercriminal ecosystem.

This week we discuss the two arrests in Australia of alleged members of the TeamPCP cybercrime group that has targeted the open source ecosystem, the US government's disclosure of intrusion activity by the Chinese QTFY threat actor, and finally the long report from OpenAI on the Hugging Face incident.

Nicole Ozer, who took the helm this year as the new executive director at the Electronic Frontier Foundation (EFF), talks to Lindsey O’Donnell-Welch about the fine line between AI empowering us and undermining our rights and privacy – and where the tipping point is.

This week we discuss the new White House memo on using private sector operators in offensive cyber operations, Lindsey's deep dive into the origins of the ExploitGym AI benchmark, and the rash of attacks on water utilities in the U.S.LinksInside ExploitGym: https://decipher.sc/2026/08/20/inside...White House memo: https://www.whitehouse.gov/presidenti...OpenAI post: https://openai.com/index/the-defender...

Adam Meyers of CrowdStrike joins Dennis to dive into the rapidly changing nature of both attacker and defender behavior in the AI age and how organizations need to shift their priorities to combat agentic threats. Then we talk about the new White House policy loosening the restrictions on private sector operators doing offensive cyper ops.

AI security pioneer and machine learning expert Gary McGraw helps Dennis separate the facts from fiction about the recent OpenAI, Meta, and Anthropic model escapes, what the real risks to enterprises are from agentic AI, and what he sees as the true threats on the horizon.

We can't go a week without an AI model escaping its bounds, and this week we talk about a new test by the AI Security Institute in which OpenAI and Anthropic models escaped the evaluation environment and tried to start a supply chain attack, then we discuss news of Zbtlink routers having a persistent backdoor.

Project Hail Mary is many things: an instant classic, a heartwarming buddy movie, a brilliant scientific tale. And it's also a pure hacker movie. Wendy Nather and David Mortman join Dennis and Lindsey to talk about Ryland Grace's hacker ethos and why he and Rocky typify the can-do attitude of hackers everywhere. It's time go!

Cybercrime has become professionalized and industrialized to the point that these groups are essentially at the level of state-backed APTs. Mike Sweeney of Silent Push joins Dennis Fisher to talk about this evolution, how AI is enabling this shift, and how defenders and vendors are working to take incremental bites out of their ecosystem.

Michael Clark, director of Threat Research at Sysdig, talks about a recent LLM-driven extortion campaign dubbed JADEPUFFER, touching on how the team discovered it, how attackers’ “intent is now legible,” and what that means for defenders.

This week we have some old-school disclosure drama when a researcher used full disclosure after months of silence from Cursor, then we discuss the enormous Patch Tuesday from Microsoft--662 bugs--and what it might mean going forward, and finally some news about DoJ sanctions and Scattered Spider members being sentenced.

Old malware like Conficker never really dies, and in industrial control and SCADA environments it can live forever undisturbed. Lesley Carhart of Dragos joins Dennis Fisher to talk about the myriad challenges of incident response in ICS networks, how ancient malware can cause trouble for years on end, and why we need more ICS security engineers desperately.

Jack Cable, co-founder and CEO of Corridor and a former senior technical advisor at CISA, discusses AI's impact on cybersecurity, vulnerability discovery, and coding practices.

It's a pre-July 4th extravaganza! To celebrate, we dive into a little cybersecurity history with a story about the MySpace Samy worm, then we jumpe into the news of the week, including an update on the Fable 5 export control drama, and the emergence of the ARToken operator panel.

Hacker and legendary vulnerability disclosure expert Katie Moussouris of Luta Security joins Dennis to talk about the Fable 5 munitions classification controversy, the recent re-emergence of the disclosure debate, how AI-assisted bug hunting is reshaping the defensive landscape, and what the future holds for attackers and defenders.
