Parce que… c'est l'épisode 0x598! Shameless plug 12 au 17 octobre 2025 - Objective by the sea v8 10 au 12 novembre 2025 - IAQ - Le Rendez-vous IA Québec 17 au 20 novembre 2025 - European Cyber Week 25 et 26 février 2026 - SéQCure 2065 Description Introduction et contexte Ce podcast technique présente un retour d'expérience fascinant sur l'utilisation de l'intelligence artificielle lors du NorthSec CTF (Capture The Flag), l'un des plus importants événements de cybersécurité en Amérique du Nord. L'animateur s'entretient avec Mickael Nadeau, qui partage son expérience de l'intégration massive de l'IA dans les compétitions de sécurité informatique. L'évolution spectaculaire de l'IA dans les CTF Une transformation radicale Mickael souligne une évolution majeure depuis leur dernier enregistrement il y a deux ans. Alors qu'à l'époque l'IA était encore balbutiante dans le domaine des CTF, elle est devenue aujourd'hui un outil incontournable qui change fondamentalement la dynamique de ces compétitions. Cette transformation s'est révélée particulièrement frappante lors du NorthSec de cette année. Intégration pratique de ChatGPT L'un des aspects les plus remarquables rapportés est l'utilisation intensive de ChatGPT par les participants. Un membre de l'équipe de Mickael s'est présenté avec une tablette dédiée exclusivement à ChatGPT, l'utilisant pour prendre des notes, analyser des problèmes et combler ses lacunes en matière de connaissances sécuritaires. Cette approche a permis à des participants moins expérimentés de rester productifs et compétitifs tout au long de l'événement. Les défis techniques spécifiques du NorthSec La complexité IPv6 Le NorthSec se distingue par son utilisation délibérée d'IPv6, un choix stratégique des organisateurs pour complexifier les défis et sortir les participants de leur zone de confort. Cette particularité a créé des situations où même les participants expérimentés comme Mickael se sont retrouvés en difficulté, ayant oublié les spécificités des outils compatibles IPv6 après deux ans d'absence. L'IA comme solution aux lacunes techniques Face à ces défis techniques, l'IA s'est révélée être un allié précieux. Les participants ont pu interroger ChatGPT sur les outils compatibles IPv6, obtenir des explications sur des concepts complexes et recevoir des suggestions d'approches qu'ils n'auraient pas nécessairement envisagées seuls. Cette assistance a considérablement réduit le temps habituellement consacré à la consultation de documentation technique. L'impact sur l'analyse et le reverse engineering Analyse de fichiers simplifiée L'une des révolutions les plus marquantes concerne l'analyse de fichiers et le reverse engineering. Mickael décrit comment il était possible de simplement télécharger un fichier dans un outil alimenté par l'IA et obtenir instantanément une analyse détaillée. Cette capacité a particulièrement impressionné l'équipe, permettant d'extraire des métadonnées, d'identifier des méthodes de chiffrement et de décompiler des fichiers Linux sans avoir besoin de l'environnement technique traditionnel. Génération d'hypothèses L'IA excelle dans la génération d'hypothèses créatives. Plutôt que de remplacer l'expertise humaine, elle complète la réflexion en proposant des pistes que les participants n'auraient pas forcément explorées. Cette collaboration homme-machine s'est révélée particulièrement efficace pour débloquer des situations complexes et accélérer la résolution de défis. Les outils et plateformes émergentes Évolution des outils en ligne Mickael observe une prolifération d'outils en ligne intégrant l'IA, permettant d'effectuer des tâches complexes directement dans un navigateur. Cette évolution est particulièrement avantageuse pour les utilisateurs de MacBook, traditionnellement désavantagés dans les CTF par rapport aux environnements Linux. La possibilité de dropper simplement un fichier et d'obtenir une analyse automatique représente un changement de paradigme majeur. Les MCP (Model Context Protocol) Bien que Mickael n'ait pas eu l'opportunité d'utiliser pleinement les MCP pendant le CTF, il exprime un vif intérêt pour cette technologie. Il envisage de développer des chaînes MCP spécifiquement configurées pour les besoins du NorthSec, notamment pour automatiser les phases de reconnaissance et l'analyse IPv6. Impact social et collaboratif Démocratisation de la participation L'un des effets les plus remarquables de l'intégration de l'IA concerne l'aspect social des CTF. Mickael rapporte que cette édition a été la plus collaborative qu'il ait jamais vécue. L'IA a permis de niveler les compétences, permettant à des participants moins expérimentés de contribuer efficacement et de rester engagés tout au long de l'événement. Fin de l'isolement technique Traditionnellement, les CTF pouvaient créer des situations où certains participants se retrouvaient isolés, incapables de suivre le rythme ou de contribuer aux discussions techniques. L'IA a brisé ces barrières en permettant à chacun d'obtenir rapidement les informations nécessaires pour participer aux échanges et proposer des solutions. Maintien de l'engagement Pour la première fois de son expérience, Mickael observe que tous les membres de l'équipe sont restés motivés et impliqués jusqu'à la fin de l'événement. Cette constance dans l'engagement contraste fortement avec les éditions précédentes où certains participants décrochaient face à la complexité des défis. Défis et limitations Limites des garde-fous Malgré les avancages considérables, l'IA présente encore des limitations. Les garde-fous intégrés dans les systèmes peuvent parfois empêcher certaines opérations légitimes dans le contexte d'un CTF. Mickael envisage d'utiliser des instances locales ou des environnements cloud dédiés pour contourner ces restrictions. Risque de sur-dépendance Bien que non explicitement mentionné, la discussion suggère la nécessité de maintenir un équilibre entre l'utilisation de l'IA et le développement des compétences fondamentales. L'IA accélère l'apprentissage mais ne remplace pas la compréhension profonde des concepts sécuritaires. Perspectives d'avenir Préparation pour 2025 Mickael exprime son désir de mieux se préparer pour la prochaine édition en développant des outils MCP spécialisés et en explorant davantage les plateformes en ligne émergentes. Il envisage également de s'entraîner sur des CTF en ligne pour perfectionner ses techniques d'intégration de l'IA. Évolution technologique rapide Les intervenants soulignent la rapidité d'évolution du domaine. Ce qui semblait impossible il y a quelques années devient routine, et ils anticipent des changements encore plus drastiques d'ici la prochaine édition du NorthSec. Conclusion Cette expérience du NorthSec 2024 illustre une transformation fondamentale dans l'approche des compétitions de cybersécurité. L'IA ne remplace pas l'expertise humaine mais la démultiplie, rendant les CTF plus accessibles, plus collaboratifs et paradoxalement plus éducatifs. Cette évolution pourrait attirer de nouveaux participants et revitaliser l'intérêt pour ces événements, tout en maintenant leur caractère technique et challengeant. L'enthousiasme de Mickael pour cette nouvelle approche est palpable, et sa suggestion d'enregistrer en direct lors du prochain CTF témoigne de la dimension sociale renforcée de ces événements. L'IA semble avoir réussi le pari de rendre les CTF à la fois plus techniques et plus humains, une contradiction apparente qui pourrait bien définir l'avenir de la cybersécurité collaborative.

Forecast = Cloudy with a chance of zero-days-watch for Spellbinder storms and scattered Git leaks! ‍ On this episode of Storm⚡️Watch, the crew dives into the fast-moving world of vulnerability tracking and threat intelligence, spotlighting how defenders are moving beyond the traditional CVE system to keep pace with real-world attacks. The show kicks off with a look at the latest listener poll, always a source of lively debate, before jumping into some of the most pressing cybersecurity stories of the week. A major focus of this episode is the recent revelation that a China-aligned APT group, dubbed TheWizards, is using a tool called Spellbinder to abuse IPv6 SLAAC for adversary-in-the-middle attacks. This technique lets attackers move laterally through networks by hijacking software update mechanisms-specifically targeting popular Chinese applications like Sogou Pinyin and Tencent QQ-to deliver malicious payloads such as the modular WizardNet backdoor. The crew unpacks how this approach leverages IPv6's stateless address autoconfiguration to intercept and redirect legitimate traffic, underscoring the evolving sophistication of lateral movement techniques in targeted campaigns. The episode then turns to Google's 2024 zero-day exploitation analysis, which reports a drop in the total number of zero-days exploited compared to last year but highlights a worrying shift: attackers are increasingly targeting enterprise products and infrastructure. Microsoft, Ivanti, Palo Alto Networks, and Cisco are among the most targeted vendors, with nearly half of all zero-day exploits now aimed at enterprise systems and network appliances. The discussion covers how attackers are chaining vulnerabilities for more impactful breaches and why defenders need to be vigilant as threat actors pivot to harder-to-monitor enterprise environments. Censys is in the spotlight for its recent research and tooling, including a new Ports & Protocols Dashboard that gives organizations granular visibility into their attack surface across all ports and protocols. This helps teams quickly spot risky exposures and misconfigurations, making it easier to prioritize remediation efforts and automate alerting for high-risk assets. The crew also highlights Censys's collaborative work on botnet hunting and their ongoing push to retire stale threat indicators, all of which are reshaping proactive defense strategies. runZero's latest insights emphasize the importance of prioritizing risks at the asset stack level, not just by CVE. The crew explains how misconfigurations, outdated software, and weak network segmentation can create stacked risks that traditional scanners might miss, urging listeners to adopt a more holistic approach to asset management and vulnerability prioritization. Rounding out the episode, GreyNoise shares new research on a dramatic spike in scanning for Ivanti Connect Secure VPNs and a surge in crawling activity targeting Git configuration files. These trends highlight the persistent risk of codebase exposure and the critical need to secure developer infrastructure, as exposed Git configs can lead to the leak of sensitive credentials and even entire codebases. As always, the show wraps up with some final thoughts and goodbyes, leaving listeners with actionable insights and a reminder to stay vigilant in the face of rapidly evolving cyber threats. If you have questions or want to hear more about any of these topics, let us know-what's on your mind this week? Storm Watch Homepage >> Learn more about GreyNoise >>

When most people think of segment routing (SR), they think of SRv6--using IPv6 addresses as segment IDs, and breaking the least significant /64 to create microsids for service differentiation. This is not, however, the only way to implement and deploy SR. The alternative is SR using MPLS labels, or SR/MPLS. Hemant Sharma joins Tom Ammon and Russ White to discuss SR/MPLS, why operators might choose MPLS over IPv6 SIDs, and other topics related to SR/MPLS. You can find Hermant's recent book on SR/MPLS here.

How do you know what is happening within your network, especially when something isn't working? Network monitoring is the answer. On today's show, we'll start with the basics of network monitoring.

Send us a textThe story of cloud networking rarely gets told from the perspective of those building it inside unicorn startups, but that's exactly what this episode delivers. Richard Olson, cloud networking expert at Canva, takes us behind the scenes of building network infrastructure for one of the world's fastest-growing SaaS platforms.Richard's fascinating career journey began with literally throwing rocks with phone lines into trees during his military service, progressing through network operations centers and pre-sales engineering before landing at AWS and eventually Canva. His unique perspective bridges traditional networking expertise with cloud-native development approaches.Unlike enterprises migrating from legacy environments, Canva started entirely in the cloud with minimal networking considerations. Richard explains how this trajectory created different challenges - starting with overlapping 10.0.0.0/16 addresses across development environments and evolving to hundreds of VPCs requiring sophisticated connectivity solutions. By mid-2022, these networking challenges had grown complex enough to warrant forming a dedicated cloud networking team, which Richard helped establish.The conversation takes a deep technical turn exploring Kubernetes networking challenges that even experienced network engineers might not anticipate. Richard explains why "Kubernetes eats IP addresses for breakfast" in cloud environments, detailing the complex interaction between VPC CIDR allocations, prefix delegations, and worker node configurations that can quickly exhaust even large IP spaces. This pressure is finally creating compelling business cases for IPv6 adoption after decades of slow uptake.Whether you're managing cloud infrastructure today or planning your organization's network strategy for tomorrow, this episode offers invaluable insights into the evolution and challenges of cloud networking at unicorn scale. Listen now to understand why companies are increasingly forming dedicated cloud networking teams and the unique skill sets they require.Connect with Richard:https://www.linkedin.com/in/richard-olson-auCheck out the Fortnightly Cloud Networking Newshttps://docs.google.com/document/d/1fkBWCGwXDUX9OfZ9_MvSVup8tJJzJeqrauaE6VPT2b0/Visit our website and subscribe: https://www.cables2clouds.com/Follow us on Twitter: https://twitter.com/cables2cloudsFollow us on YouTube: https://www.youtube.com/@cables2clouds/Follow us on TikTok: https://www.tiktok.com/@cables2cloudsMerch Store: https://store.cables2clouds.com/Join the Discord Study group: https://artofneteng.com/iaatj
