Prototype pollution is a vulnerability in JavaScript applications that can have varying impacts depending on the complexity and nature of the affected app. It exploits the prototype inheritance feature of JavaScript, which allows objects to inherit properties and methods. By manipulating the prototype chain of an object, an attacker can introduce malicious properties, leading to […]

DOM XSS continues to be the most critical threat to web security. Our current best defense against DOM XSS is Trusted Types, a browser-based runtime feature to limit the uses of DOM APIs (and limit the possibility of DOM injection). We will discuss our approach to using Trusted Types to protect billions of our users, […]

De nos jours les antivirus, pour détecter les malware, reposent principalement sur l'analyse dynamique. Pour analyser le comportement d'un malware, il est nécessaire que les solutions d'antivirus aient le moyen d'intercepter ses actions. Pour cela, Microsoft a ajouté au sein de l'OS Windows ce que l'on appelle des kernel callbacks. Ces kernels callbacks sont en […]

Lors de missions de type intrusion physique, les auditeurs se retrouvent face à différents blocages physiques. Le but de cette présentation a pour objectif de démontrer que nombreux de ces dispositifs de blocage peuvent être contournés facilement et sans entraînement. En effet, qui ne s’est jamais retrouvé face à un Digicode en métal ? Une […]

Souvent utilisé pour stocker les secrets critiques du système d'information, KeePass est une cible de choix pour les attaquants. Parmi ses nombreuses fonctionnalités, le logiciel propose un système d’événement-action-condition permettant l'automatisation de tâches complexes. Ce dernier fut rapidement détourné afin d'extraire les mots de passe par simple modification d'un fichier de configuration. Particulièrement discrète, cette […]

Cricut made a pretty bad move in March 2021 when they decided to limit the use of their crafting machines to users who did not subscribe to a paid account. The community rebelled and Cricut stepped back, while their PR department tried to extinguish the bad buzz. But something has started. People are more and […]

Les serveurs et applications web reposent sur des technologies qui peuvent dans certains cas être détournées et utilisées à des fins non-prévues. Il est ainsi possible de parasiter un serveur ou une application en y stockant des données sans que ces derniers ne s'en rendent compte tout en permettant leur récupération dans un délai plus […]

Parmi les serrures mécaniques, les systèmes magnétiques sont considérés (en général à juste titre) comme les plus sécurisés. Par design, ces sûretés sont protégées contre les méthodes de bumpkeys, pickgun, ou encore l'impressioning. Ces serrures sont également plus difficiles à crocheter, et leurs clés sont plus difficiles à copier. Mais surtout, ces systèmes sont trop […]
