Decipher Security Podcast

Bestselling author, podcaster, and all around great guy Shea Serrano joins Dennis Fisher and Lindsey O’Donnell-Welch to explore why Catch Me If You Can is more than a con-artist story: it’s a hacker classic and master class in social engineering, confidence, and deception. We unpack Leonardo DiCaprio’s performance, Spielberg’s tension-building, and the film’s memorable cast and scenes. Along the way, the conversation connects the movie to hacker culture and cybersecurity, and asks why Frank Abagnale’s cons still fascinate us today.LinksSubscribe to Shea's Good Movie newsletter: https://substack.com/@sheaserrano

Today we have for you a buffet of zero days being exploited in edge security products, including Citrix and Fortinet, then we discuss the importance of communications from vendors when bad things happen, and finally we preview VulnCheck's THREATCON1, which takes place next week.

Ben Harris of watchTowr joins Dennis Fisher to walk through the Citrix NetScaler zero days that emerged over the weekend, from first detection of exploitation to reporting to finally some patches and why vendor communication is so vital in these cases.

Ryan Fetterman from Cisco Talos sits down with Decipher’s Lindsey O’Donnell-Welch to talk about ClosedQuorum, the first reported malware binary with an autonomous command-and-control. They talk about the wide range of ways threat actors are using AI, and useful detection strategies for AI-assisted attacks.

This week we dig into the ShinyHunters hack of the FBI and what it means not just for the FBI personnel but for the attackers, then we discuss the disruption of the EvilTokens phishing operation by Microsoft, and finally we talk about the F5 BIG-IP zero day and some odds and ends from LabsCon.LinksFBI hack: https://x.com/FBI/status/210280781969...EvilTokens disruption: https://www.microsoft.com/en-us/secur...F5 zero day: https://decipher.sc/2026/09/24/f5-cve...watchTowr Labs post: https://labs.watchtowr.com/is-this-a-...

The security and reliability of the code in AI models is a huge question mark, because the models are black boxes that aren't accessible to outsiders. Matt Fredrikson, professor at Carnegie Mellon University and founder of Gray Swan AI, joins Dennis to talk about the challenge of assessing these models and how a community of red teamers is trying to meet it.

Dennis joins from the last LabsCon conference, which featured amazing keynotes from Prof. James Mickens on AI reality and myths, Katie Moussouris on why humans are more vital than ever in security, and Dino Dai Zovi on using hardware to break attack chains,

You've heard all of the hysteria around the vulnpocalypse caused by AI-assisted bug hunting and the shrinking time to exploit window. Now Jeremiah Grossman dispels those myths and shows exactly what the data reveals about how many bugs are actually exploited and how long it takes for attackers to target them.

This week we dive into Anthropic's new threat intelligence report, how cybercriminals are using AI in their campaigns, and the profound effect that 9/11 had on the cybersecurity industry. Then, Dennis is joined by Ryan Naraine to preview LabsCon and talk about the keynotes by Katie Moussouris, Dino Dai Zovi, and James Mickens.
