Audio-visual (AV) equipment is everywhere – meeting rooms, auditoriums, and control centres – but how often do we think about its security?

In this episode of the mnemonic security podcast, Robby talks to Øystein Stadskleiv from Leteng, about the overlooked risks of AV systems. They discuss real-world attack scenarios, common vulnerabilities, and practical steps to secure AV infrastructure.

In this episode of the mnemonic security podcast, Robby is joined by Emil Vaagland, Security Manager at FINN.no, Norway’s leading online marketplace.

They discuss the unique security challenges of a cloud-first, developer-heavy organisation, covering everything from vulnerability management and secure coding, to fraud detection and access control. Vaagland shares insights into their approach to bug bounties, DevSecOps, and balancing security with developer efficiency.

In this episode of the mnemonic security podcast, Robby is joined by Dustin Childs, Head of Threat Awareness at Trend Micro’s Zero Day Initiative (ZDI). Dustin explains the ZDI’s role in purchasing and analysing vulnerabilities to provide early protection for customers and how zero days – previously unknown vulnerabilities – become "n-days" once disclosed or patched.

The conversation highlights the critical importance of timely patching, the risks posed by bad patches, and the concept of virtual patching as a defence strategy. Dustin also delves into attack surface monitoring, the evolving threat landscape, and the ongoing challenges of balancing security and usability in modern networks.

In this episode of the mnemonic security podcast, Robby is joined by Eirik Nordbø and Marius Kotlarz from Equinor, as well as Haakon Staff from mnemonic.

Together, they discuss the world of Capture the Flag (CTF) competitions, exploring their origins, structure, and benefits. CTFs, as they explain, are “hacking” contests featuring challenges such as cryptography and reverse engineering, where participants solve tasks to uncover "flags" and earn points.

The discussion highlights the educational value of CTFs, particularly in helping developers, pentesters, and other IT professionals refine their skills and master advanced techniques. The group also addresses the logistical challenges of hosting a CTF—such as the Equinor CTF—from infrastructure setup to stress testing, while emphasizing the passion and expertise required to organize a successful event. Finally, they explore how CTFs can serve as a valuable recruitment tool for identifying and attracting top security talent.

To kick off 2025, Robby chats with Duncan Ogilvie, a renowned expert in Reverse Engineering (RE), the creator of x64dbg (a popular open-source x64/x32 debugger for Windows), and the mind behind 100+ other cool projects.

Their conversation covers the evolving field of RE, discussing common challenges, practical techniques, and how professionals navigate the landscape. Duncan also shares his insights on the current tools shaping the field, explores the role of "AI" in RE, and speculates on what the future might hold for the industry niche.

Listeners will also get a sneak peek into Duncan’s upcoming course, scheduled for February 20-21 in Oslo. The course will focus on using LLVM for binary analysis and is designed to help intermediate reverse engineers sharpen their skills. If you’re interested, sign up here!

In this episode of the mnemonic security podcast, Robby is joined by Tony Fergusson, CISO EMEA at Zscaler. They start with a market update on Zero Trust and discuss the challenges relating to adoption that he has observed (ever heard of the Popcorn Theory?). 

Fergusson then introduces the concept of risk hunting – a proactive strategy to identify and mitigate risks before they escalate into breaches – and explains how it relates to threat hunting. He emphasizes the importance of least privilege, continuous evaluation, and what Zero Trust looks like for users and workloads.

In this episode of the mnemonic security podcast, Robby is joined by Scott Piper from Wiz and Håkon Sørum from O3 Cyber to talk cloud security. 

They cover the evolution of cloud security products since Amazon's release of S3 and EC2 in 2006 and how the market has matured into the CNAPP we know today.  They chime in on most of the buzzwords associated with CNAPP, including Cloud Security Posture Management (CSPM), Cloud Workload Protection Platform (CWPP), Cloud Infrastructure Entitlement Management (CIEM), and Cloud Detection and Response (CDR), as well as other key areas of CNAPP such as vulnerability scanning, "shift-left" security, cloud data security, and compliance.   

They explain the definition and challenges of "cloud-native attacks" and misconfigurations and discuss whether third-party SOCs can add context and enhance detection capabilities.

In this episode, Robby is joined by Maximilian Heinemeyer, Chief Product Officer at Darktrace.

The conversation focuses on Max's perspective on detection engineering and the use of machine learning. He shares his opinion on the limitations of traditional, signature/behaviour-based detection methods and the challenges organisations face when building complex detection engineering systems.

Max contrasts these traditional approaches with the unsupervised machine learning techniques used by Darktrace, and describes the "aha moments" he experienced when seeing this technology work in its early days.

In this new episode of the mnemonic security podcast, Robby Peralta is joined by Leonid Rozenberg, a cybersecurity expert and dark web researcher at Hudson Rock, to discuss infostealers. Rozenberg provides a brief history of infostealers, which began with Zeus in 2007, a malware initially designed to steal only banking information. Today, infostealers have evolved to capture all types of personal and sensitive data, including passwords, cookies, and cryptocurrency information. Infostealer malware can be bought on the dark web as a turnkey solution, or "mass malware as a service," for as little as $99 per month.

Rozenberg emphasises the importance of cybersecurity education and debunks common misconceptions about antivirus protection, complex passwords, and multi-factor authentication. He also highlights the ongoing threat of infostealers and their adaptability in bypassing security measures.

Joe Slowik, ATT&CK CTI Lead at MITRE, joins the latest episode of the mnemonic security podcast to share his insights on the complexities of securing critical infrastructure. With a background in cyber threat intelligence, incident response, and detection engineering, Joe discusses with Robby the challenge of defining and prioritising what's truly "critical" in a landscape where every sector claims importance.

They explore the difficulty in distributing security investments across industries and the growing need for organisations of all sizes to adopt a mindset of self-defence. Joe also addresses the potential consequences of large-scale cyberattacks, such as those by Volt Typhoon, emphasising the need for coordinated incident response and leadership during crisis scenarios. He concludes with a strong call for resilience and highlights the vital role CEOs play in ensuring organisational preparedness.
