Kevin Mitnick - le hacker le plus recherché du FBI

Cet article fait partie de ma série de l’été spécial hackers. Bonne lecture !

Imaginez un mec capable de lancer une guerre nucléaire en sifflant dans un téléphone public ? Non, je ne vous parle pas d’un super-vilain de James Bond, mais bien de Kevin Mitnick selon… le FBI américain. Bienvenue dans les années 90, où les juges prenaient au sérieux l’idée qu’un hacker puisse pirater le NORAD à coups de sifflets. Du délire j’vous dis ! Et pourtant, cette absurdité n’est qu’un aperçu de la légende urbaine qu’est devenu Kevin David Mitnick, probablement le hacker le plus fascinant et mal compris de l’histoire de l’informatique.

SHADE-Arena - Quand les IA apprennent à nous saborder en douce

J’étais tranquillement en train de lire le dernier papier d’Anthropic avec mon café quand mon chat (Percy) m’a regardé avec son regard de psychopathe, semblant me demander pourquoi j’avais l’air de quelqu’un qui venait de voir un fantôme. La vraie raison, c’est que je viens de découvrir qu’Anthropic testait maintenant comment les IA pouvaient nous mentir en pleine face au travers de leur projet SHADE-Arena. Derrière ce nom un peu barbare se cache en réalité un laboratoire secret pour mesurer les capacités de sabotage de nos assistants virtuels préférés.

DecompAI - L'IA qui révolutionne le reverse engineering

Si vous aimez faire un peu de reverse engineering, et que souvent, vous galérez à déchiffrer du code assembleur qui ressemble à des hiéroglyphes, alors voici un outil qui devrait vous plaire. Développé par les frenchies Louis Gauthier et Clément Florval, DecompAI transforme vos sessions d’analyse de binaires en conversations parfaitement naturelles pour décortiquer vos binaires.

Avec DecompAI, c’est terminé le jonglage permanent entre différents outils tels que Ghidra pour décompiler, GDB pour débugger, objdump pour désassembler, ou radare2 pour analyser. Cette fragmentation vous oblige à maintenir mentalement le contexte entre les applications, ça ralentit votre workflow et ça multiplie les risques d’erreur. Du coup, cette approche conversationnelle a son intérêt car au lieu de mémoriser des dizaines de commandes cryptiques, vous décrivez simplement vos besoins en langage naturel du genre : “Décompile-moi la fonction main”, “Montre-moi les strings intéressantes” ou “Analyse cette fonction suspecte”. L’agent DecompAI orchestre alors automatiquement les bons outils avec les paramètres appropriés.

SpellRing is an AI-enabled smart ring that converts American Sign Language into phone text

People who are deaf or cannot speak, or both – have long been aided by the American Sign Language (ASL) in communicating with people. Although the accuracy of the communication solely depends on the understanding of people on both ends, that can be a problem if one or more conversants are not that fluent in ASL. Researchers at Cornell University have recognized this problem and want to leverage the goodness of wearable technologies to make it smoother for people who are differently abled to communicate with the world as they intend to.

The experts at the university have employed the smart ring platform to develop a wearable that tracks the American Sign Language gestures of the wearer to accurately transcribe them into understandable text or audio to a computer or a smartphone. They call it the SpellRing, and it can be worn on the thumb to get the desired input for the translated data. The wearable comes with embedded sensors including a mini-gyroscope to measure the angular data from hand movement. The on-board speakers and mic detect the inaudible sound waves from the movement. All these components are housed inside a 3D-printed housing that’s no more than the size of a quarter.

Designer: Cornell University

The smart AI ring can detect all 26 letters in the English language with micro-sonar technology to precisely track the fingerspelling of the wearer. For more accuracy sonar images are also fed into the system. The data that is received from all the sensors and hardware is then processed by a deep-learning algorithm. All of this is done in a split second time to predict the ASL fingerspelled by the wearer. To make possible an in-depth and unbiased view of the wearable for further development, the researchers from Carnegie Mellon University and Stony Brook University, along with the researchers from Cornell University have tested the wearable thoroughly.

In the conducted tests, 20 amateur and experienced ASL signers were asked to spell more than 20,000 words to see the accuracy of the AI-assisted wearable ring. The 3D-printed wearable passed with a combined accuracy of around 90 percent with both signed words, as well as, sentences. It was even tested to perform actions such as web search, map navigation, or typing in notes with the input. According to Hyunchul Lim, lead author of SpellRing’s papered documentation, “ASL is a very complicated, complex visual language,” and the focus is right now on tuning the algorithm to make the AI ring understand words and phrases with maximum accuracy.

The SpellRing is currently in the prototype stage and there is no word on the availability of the ring yet. The team is confident that even in the current stage, ASL fingertyping will be significantly faster than typing on your smartphone’s keyboard. Researchers want this ring to be a tool for fast and accessible text entry with a niche set of benefits targeted toward a set of users. The prospects of this AI ring graduating to the wearable market are very high since it costs just $30 to make the current prototype AI ring. When it will be mass produced that cost can be further trimmed down.

Teenage Engineering-inspired flashlight concept breaks the mold with a boxy design

In the course of using some everyday products, we probably seldom stop to question why things are designed the way they are. Why are appliances like speakers and air purifiers traditionally rectangular and boxy while flashlights and lamps are cylindrical? Sometimes, the answers lie in history and practicality, but other times it’s just a matter of convention and the lack of motivation to think outside the box.

This flashlight design concept, however, isn’t afraid to dare to be different, perhaps even to the point of sacrificing some ergonomics. Embracing a trending design aesthetic, it isn’t just breaking the mold by throwing out most conventions. It is also challenging those conventions to see what’s possible if we’re not afraid to ask “What if?”

Designer: Nikhil Kapoor

Industrial design aesthetics has carried a rather negative connotation of being cold and impersonal, but recent trends have cast a more positive light on modern renditions of the design language. Teenage Engineering’s products, in particular, have presented a certain flavor of minimalism that embraced the cold surface of metal, the angular and sharp edges of boxes, and an intentionally limited color palette.

The FL-1 flashlight concept embraces these design elements to shock and confound. Instead of the conventional barrel form, it comes in a box that will admittedly be cumbersome to hold for long periods of time, at least depending on the size. It could easily fit in the palm of your hand, as many EDC flashlights do these days, but the sharp edges could bite into your skin over time.

The design does have a few interesting features beyond its industrial aesthetic. The rectangular shape gives it enough room to fit two LED lights, which can be turned on individually or together with a simple sliding switch mechanism. There’s also a display to show the remaining battery charge so you’re never caught unaware. The flashlight is charged via USB-C, which is the only reference to the correct scale of the object.

Like Teenage Engineering’s designs, the FL-1 practically uses only two colors, or three if you count the contrasting shade of gray. A vibrant orange backside increases its visibility, but only if it’s upside down, while there’s no method for seeing the flashlight in the dark if it’s right side up. The concept definitely has its flaws, but it is still a worthwhile thought experiment on how we can challenge the status quo and come up with designs that aren’t just different but also even better.
