    #600: This Free Tool Decodes Game Boy ROM From a Photograph

    Can you recover working software from a photograph of a microchip? Embedded systems reverse engineer Travis Goodspeed demonstrates how to extract the original Game Boy’s 256-byte boot ROM from a microscopic photograph of the mask ROM inside its CPU. The source image was created by combining 22 microscope photographs captured at 50x magnification. Using his free, open-source Mask ROM Tool, Travis marks 2,048 ROM bit locations, separates the ones from the zeros and checks for possible recognition errors. He then determines the logical order of the bits, disassembles the program and shows how it can be exported as a ROM file for use in an emulator. Travis also explains the Game Boy’s unusual copy-protection system. During startup, its boot ROM displays logo data supplied by the cartridge and compares it with Nintendo’s internal copy. If the logos do not match, the game does not boot. Requiring cartridges to contain Nintendo’s trademark gave the company legal leverage against unlicensed publishers. The video also explores techniques from Travis’s book, Microcontroller Exploits. These include extracting protected firmware from an access-control reader, chemically decapsulating chips while preserving their operation and using ultraviolet light with a nail-polish mask to remove memory protection without erasing the program. The Mask ROM Tool, Game Boy chip photograph and step-by-step tutorial are publicly available, allowing you to reproduce the ROM-decoding demonstration without owning a microscope or chemistry lab. // Sponsored SEGMENT // Big thank you to Proton Pass for sponsoring this video.

    #599: This Pocket Tool Diagnoses Wi-Fi in 45 Seconds

    Your internet speed can look fine while your Wi-Fi is still failing. Packet loss, latency, congested channels, interference and poor configuration can all damage performance, but a normal speed test will not show you the full picture. In this video, I test the Ookla Speedtest Pulse, a pocket-sized Wi-Fi 7 diagnostic tool that measures more than 25 network metrics in around 45 seconds. We test Wi-Fi at the Natural History Museum in London and examine results from an Airbnb to identify whether the problem comes from the Wi-Fi network, wired connection or internet service provider. Matt explains how the device tests 2.4, 5 and 6 GHz Wi-Fi, detects channel problems, measures signal quality and gives you practical recommendations in plain English. We also compare Speedtest Pulse with the normal Speedtest application, laptopbased tools and the Ekahau Sidekick 2. You will see its current limitations, upcoming continuous monitoring features and how it could help technicians finally capture intermittent Wi-Fi problems. Big thanks to OOKLA for sponsoring this video.

    #598: AI Can’t Understand Intent. That’s a Security Problem

    Big thanks to ThreatLocker for sponsoring my trip to Black Hat USA 2026 and also for sponsoring this video. To start your free trial with ThreatLocker please use the following link: https://www.threatlocker.com/davidbombal AI is changing cybersecurity, but simply using more AI to defend against AI attacks may not be the answer. David Bombal sits down with Danny Jenkins, CEO of ThreatLocker, to discuss the security risks created by AI, autonomous agents, zero-day vulnerabilities, ransomware, and the rapidly expanding attack surface businesses now have to deal with. Danny explains one of the fundamental problems with AI security: AI can understand what something does, but it may not understand the intent behind it. The same action could be performed legitimately by an administrator or maliciously by an attacker. They also discuss how AI is giving attackers capabilities that previously required significantly more expertise and resources, including vulnerability discovery and sophisticated phishing attacks. But AI creates another problem inside organizations. Autonomous agents can potentially access files, upload data, perform actions, and make mistakes extremely quickly. Every new piece of software adds attack surface, and powerful AI agents can dramatically increase that risk. Danny argues that the answer isn't simply AI versus AI. Instead, organizations need to rethink trust itself. The discussion covers deny by default, application control, restricting what software and AI agents are allowed to access, and why AI should be used as an additional security layer rather than becoming your primary defense. Topics include: • AI security risks • Autonomous and agentic AI • Why AI struggles with intent • How hackers are using AI • AI-powered vulnerability discovery • Zero-day vulnerabilities • Ransomware • AI attack surfaces • Application control • Deny by default security • Why AI alone can't solve AI security • Securing AI inside businesses // Danny Jenkins’ SOCIAL // LinkedIn: / dannyjenkinscyber // ThreatLocker’s SOCIAL // LinkedIn: https://www.linkedin.com/company/thre...

    #596: This is the Real Cybersecurity Problem

    Thank you to Threatlocker for sponsoring my trip to Black Hat so I can interview amazing people. Jen Easterly joins David Bombal to discuss why today’s cybersecurity problem may actually be a software quality problem. For decades, users and organizations have been blamed for failing to patch systems, change default passwords, or enable MFA. Jen argues that the bigger question is whether software vendors should be held responsible for shipping insecure products in the first place. They discuss Secure by Design, software vulnerabilities, memory safety, AI security, zero-day attacks, rogue AI agents, critical infrastructure, vendor accountability, and how artificial intelligence could dramatically shorten the time between discovering a vulnerability and weaponizing it. Jen also shares lessons from her career at the NSA, the White House, CISA, Morgan Stanley, the U.S. Army, and now RSAC, including her advice for hackers, cybersecurity professionals, and future leaders. Topics include: Why cybersecurity may be a software quality problem Why users are blamed for insecure software CISA’s Secure by Design initiative Why default passwords should disappear AI agents behaving in unexpected ways AI and the future of zero-day attacks Memory safety, C, C++ and Rust Government regulation and vendor accountability The EU Cyber Resilience Act Why Patch Tuesday may eventually become unacceptable How AI could help defenders find and fix vulnerabilities Jen Easterly’s advice for cybersecurity professionals If you work in cybersecurity, ethical hacking, software development, networking, AI security, or critical infrastructure, this is a conversation you don’t want to miss. // Jen Easterly’s SOCIAL // LinkedIn: / jen-easterly // Website REFERENCE // https://www.cisa.gov/ // David's SOCIAL // Discord: discord.com/invite/usKSyzb Twitter: www.twitter.com/davidbombal Instagram: www.instagram.com/davidbombal LinkedIn: www.linkedin.com/in/davidbombal Facebook: www.facebook.com/davidbombal.co TikTok: tiktok.com/@davidbombal YouTube: / @davidbombal Spotify: open.spotify.com/show/3f6k6gE...

    #594: How to Protect Your Network From Insecure IoT Devices

    Hackers are using overlooked IoT devices such as IP cameras, printers and smart speakers to gain access to networks and spread ransomware. Philip Wylie explains how an outdated IP camera became a ransomware gateway, why default passwords and poor segmentation remain serious risks, and how to protect your network using separate VLANs, firmware updates, monitoring and zero-trust controls. The interview also explores medical devices, OT security, AI-enabled devices and the growing demand for IoT penetration-testing skills.

    #593: How to pass the CCNA exam (advice from two Cisco instructors)

    Two Cisco training veterans break down how to know you are ready for the CCNA exam, what changes in CCNA 2.0, and whether the CCNA is still worth it in 2026. Brian Bays has been teaching official Cisco classes since 2000. Michael Aldridge has been writing practice exam content since 2001. In this interview they answer the questions I get asked constantly: how long should I study, do I need physical equipment, should I do Network Plus first, and is AI going to take these jobs away? Short answer on that last one: they have heard this before. Automation was going to end tech jobs. Then virtualization. Then cloud. Every time, it just made good engineers more productive. Junior engineers become senior engineers, and we cannot function without senior engineers. We also cover what is coming in CCNA 2.0, including more troubleshooting woven through every section, a dark mode option, a full screen CLI, and the ability to send a command to every device in a lab at once. This video is not sponsored. I have known Brian and Michael for years and I recommend them because I rate them, not because anyone paid for this.
