Initiation à la classification de malware FR Ce workshop propose une découverte de la classification de malware, en partant des bases pour construire un système scalable de recherche et de classification. On commencera par explorer l’intérêt de chercher des similarités entre binaires. J'aborderai les méthodes classiques de diffing binaire (BinDiff, Diaphora), avant de passer à une approche plus globale pour mesurer la similarité à grande échelle, à partir de features extraites des binaires. Les participants découvriront comment appliquer des méthodes de comparaison efficaces pour classifier de grands volumes de binaires, tout en gardant une durée de traitement réaliste. Nous évaluerons les performances des modèles à l’aide d'outils classiques de machine learning, puis visualiserons les résultats avec des graphes (neo4j) qui donnent des résultats plus visuels. L'objectif final est de créer un outil simple de classification et de recherche de similarité basé sur Python et Docker

Breaking into Hades' realm: an advanced Kerberos exploitation EN Originally developed by MIT, Kerberos is widely used in Microsoft Active Directory environments. Therefore, this protocol is a prime target for exploitation, allowing privilege escalation as well as establishing persistence. This workshop is designed for cybersecurity professionals who seek to deepen their understanding of Kerberos vulnerabilities and the sophisticated techniques used to exploit them. Participants will embark on a comprehensive journey on Kerberos exploitation, starting with the fundamentals of the protocol and moving swiftly into advanced attack strategies. The workshop will primarily cover: - Abusing delegations - Forging tickets (especially Diamond and Sapphire tickets) - *-roasting (well-known variants as well as their newer versions, such as Kerberoasting without pre-authentication) Throughout the workshop, participants will engage in hands-on labs to reinforce their learning. By the end of the session, attendees will possess a deep understanding of Kerberos exploitation techniques and practical knowledge to effectively conduct these attacks. Join us to master the art of Kerberos exploitation and fortify your skills to always be Domain Admin on the first day of your pentest engagement Requirements: - Basic knowledge of Active Directory and Kerberos protocol - A laptop with Exegol (https://exegol.readthedocs.io) pre-installed, with the latest nightly image already downloaded

Playing the game of tag with modern day AV and EDRs: A guide to evading the watchdogs. FR The perpetual race to safeguard and secure our infrastructures have given birth to robust defensive mechanisms, such as antiviruses (AV), Endpoint Detection and Response (EDRs), and Extended detection and response (XDR) just to name a few. Over the years the detection methodologies employed by them have evolved. From the very basic string and hash matching techniques, defensive mechanisms have enhanced their capabilities by employing machine learning, in memory scanning and other sophisticated techniques. From the perspective of a malware developer, developing malware is considerably easier as compared to evading it. In this talk we will discuss various techniques employed by malware developers to circumvent detection measures implemented by modern day AVs and EDRs. This talk will solely focus on the Windows ecosystem. We will discuss the nitty gritties of the Windows OS, followed by various detection techniques implemented by AVs and EDRs. After understanding the detection methods we will shift our focus on various techniques that can be implemented to bypass aforementioned detection techniques. Some techniques included are Unhooking, BlockDLL, Repatching, API Hashing, ETW and AMSI patching etc. In order to better understand the concepts discussed, we present real life PoCs. These PoCs will showcase the discussed evasion techniques on a popular red teaming tool (Juicy Potato). The implemented techniques will be tested against ‘Windows Defender’, a popular and widely used inbuilt AV solution by Microsoft. Furthermore these PoCs will showcase the exact detection methods and how we were able to bypass them to gain access.

Active Directory pwnage with NetExec FR In this workshop, we will show you how to take advantage of NetExec to efficiently and easily compromise an Active Directory domain during an internal pentest. A lab will be provided to each student, and the goal will be to become a domain administrator using various paths—only with NetExec! The first one to gain domain admin will be covered in glory for eternity! In this workshop, you will learn which features to use depending on the attack you need to perform, which commands to run first, what to do when you grab credentials, etc.—all by actually doing it live. No slides, only NXC as your best friend! This workshop is for students who have already played a little with Active Directory or for people who want to learn more about the tool and how to use it properly during an internal pentest!

Network protocol abuse: driving ICS equipent mad. FR Ce Workshop s'articulera sur les explications et l'utilisations de plusieurs librairies qui permette de s'interfacez avec de PLC (microcontrôleur programmable destiné au contrôle industriel). Une 1ʳᵉ partie sera dédiée aux explications techniques du fonctionnement des PLC et des différents protocoles réseaux associé. La deuxième partie sera sur "l'exploitation" et l'explication des libraires qui permette de s'interfacer avec les PLC. Protocoles utilisés dans le workshop : - MODBUS - s7comm (siemens) - OPC UA L'objectif de ce workshop et de démontrer la faciliter avec laquelle, on peut prendre le contrôle d'un PLC si aucune mesure de sécurité n'est appliqué, ou que des mauvaises configurations sont mises en place. Le support du workshop sont des équipements physiques qui sont contenus dans un Lab réseaux portables. Les participants pourront se connecter au LAB via RJ45 (limiter à 5 personnes) ou par wifi (20 personnes).

Integrating secure coding to DevSecOps cycle FR This workshop aims to overcome the drawbacks of the current approach of teaching application security by blindly attacking applications to analyze vulnerabilities. This results in engineers being unable to figure out the proper fix for the vulnerabilities and hence allowing attackers to exploit the same. The labs will help security enthusiasts, developers and students to identify the root cause of the vulnerability in the code, patch it, re-deploy the application, and finally verify the fix. As an attendee, you will learn to find vulnerabilities with both an attacker and a defenders point of view which would help in a swift SDLC of fixing and moving forward instead of traditional pentesting procedures of fixing the issues at the end of the cycle. The demonstration will be done using a vulnerable e-cart application with microservice architecture which is deployed using docker where the vulnerable code is attacked and replaced with secure code snippets, compiled, deployed and pentested again to demonstrate how fixing a vulnerability at the root saves engineers time and efforts.

I also provide occasional training in ethical hacking and cybersecurity awareness.
Insecure time-based secret in web applications and Sandwich attack exploitation FR The goal of this workshop is to put ourselves in the shoes of a bug bounty researcher wishing to automate an attack scenario to the maximum of its possibilities. The scenario studied will be that of a password reset token based on a time-based secret that is not cryptographically secure. We will look at how to construct the attack scenario and script a detection and exploitation procedure. We will then look at how to use the open source tool "Reset tolkien" to detect and exploit this type of web vulnerability.
