And what happens when one malicious instruction spreads between AI agents? I’m joined by Harriet, author of Practical AI Security, to explore how AI models and agents can be manipulated, with practical Python demonstrations. You'll see an image classifier misidentify a rifle, a demonstration of prompt injection spreading across five agents, and how memory poisoning can plant instructions that affect an agent later. We discuss why securing AI takes more than blocking prompt injection, how machine learning creates different security challenges, and what you need to understand before deploying agents in your organisation. Want to learn this yourself? Harriet explains how to get started with her collection of 30+ free Python notebooks, including examples you can explore in Google Colab. We also discuss the skills involved in AI security and how people from different backgrounds can contribute. Topics include: • Adversarial machine learning and image manipulation • Prompt injection and attacks spreading between agents • Memory poisoning and model backdoors • AI supply chain security • Learning AI security with Python • AI security careers, training and fundamentals // Link to No Starch Website for Harriet Farlow’s Book // Order Practical AI Security on No Starch: https://nostarch.com/practical-ai-sec...

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 Is Microsoft Defender enough to protect your PC? Malware researcher Leo joins me at Black Hat to discuss antivirus, Windows security and how hackers steal your accounts. We explore how infostealers target saved passwords and session tokens, why two-factor authentication cannot prevent every account takeover, and how a message from a compromised friend’s account can lead to an infection. Leo shares practical starting points for investigating your computer, including Autoruns for startup entries, TCPView for linking connections to applications, and Wireshark for examining network traffic. We also discuss password managers, account recovery planning, Windows telemetry and why switching operating systems does not eliminate security risks. In this interview: • Microsoft Defender’s strengths and limitations • Free tools for investigating suspicious Windows activity • How infostealers and initial access brokers operate • Stolen session tokens and the limits of 2FA • Fake download sites, malicious ads and targeted phishing • Preparing recovery options before your accounts are compromised • Security and privacy trade-offs across Windows, Linux and macOS // Leo’s SOCIAL // YouTube: / @pcsecuritychannel X: https://x.com/leotday Discord: / discord // 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...

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 Is cybersecurity still worth learning in 2026? AI agents are changing vulnerability research, but where does that leave you? At Black Hat, I’m joined by Arizona State University professor Yan Shoshitaishvili to discuss what AI can actually do, where it falls short, and why he would still choose a career in cybersecurity today. Yan shares how his lab used AI agents and human-designed workflows to find what he describes as over 1,000 Linux kernel vulnerabilities triggerable by an unprivileged local user. Running 128 agents was only part of the story. Understanding which vulnerabilities to look for and improving the research process proved critical. We discuss: • How AI agents test potential vulnerabilities instead of simply reporting suspected bugs • How agentic AI compares with fuzzing and static analysis • Why finding new bugs does not automatically prove one tool is better • Why human expertise still matters in security research • How to use AI as a learning assistant without skipping the learning • Free, hands-on cybersecurity training through pwn.college • Yan’s advice for anyone considering cybersecurity in 2026 // Yan Shoshitaishvili SOCIAL // LinkedIn: / yan-shoshitaishvili-7024305 ASU website: https://www.asu.edu/ // ThreatLocker’s SOCIAL // LinkedIn: https://www.linkedin.com/company/thre...

Your license plate could reveal more than you think. Flock cameras, vehicle tracking and OSINT can turn information about your car into clues about where you live and your daily routines. I’m joined by an OSINT expert to discuss how vehicle information can be connected with public records, why surveillance raises privacy concerns and what happens when people trust an incorrect license plate match. He shares his experiences of locating a missing car after a police search came up short and investigating a hit-and-run using a partial plate and publicly available information. We discuss: • Flock cameras and vehicle identification beyond license plates • How vehicle data can expose patterns in your movements • License plate recognition errors and the importance of verification • How public records can connect a vehicle to a person • The risks of surveillance access being abused • Privacy measures, their limitations and the need for accountability • DeFlock and community scrutiny of surveillance cameras How much can someone discover about you from the information you leave exposed? // Mishaal Kahn’s SOCIALS // LinkedIn: / mish-aal Website: https://www.mishaalkhan.com/ Tool created: https://www.operationprivacy.com/ // 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...

John DiMaggio created fake identities, profiled ransomware operators and spent approximately 18 months earning the trust of LockBit. In this interview, John explains how his investigation led to work with the FBI and the UK’s National Crime Agency, contributed to indictments and resulted in death threats against him. He also reveals how the work affected his mental health, relationships and everyday life. John shares the remarkable story of a young REvil hacker connected to the Kaseya ransomware attack and its $70 million ransom demand. He explains how ransomware operators are recruited, manipulated and sometimes controlled by intelligence agencies. You will also learn why stolen cryptocurrency is difficult to spend, how Bitcoin tracing and money-laundering mistakes expose cybercriminals and why technical hacking skills do not make someone good at hiding money. Finally, John warns aspiring researchers not to approach ransomware gangs without professional training and support. He discusses his new book, Owned, and how he plans to use his experience to help cybersecurity teams and business leaders prepare for ransomware attacks. // Link to No Starch Website for Jon DiMaggio’s Book // Order Owned on No Starch: https://nostarch.com/owned Use Coupon Code OWNED30 for 30% off Owned at NoStarch.com // Jon DiMaggio’s SOCIALS // Website: https://arkemcyber.com/ X: https://x.com/Jon__DiMaggio LinkedIn: / jondimaggio // 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...
