LLM Poisoning [1/3] - Lire les pensées d'un Transformer

08/10/2025 Votre LLM local peut vous hacker. Cette série en trois volets révèle comment de minuscules modifications de poids peuvent implanter des portes dérobées furtives restant dormantes au quotidien, puis se déclenchant sur des entrées spécifiques, transformant un modèle "sûr" et même hors-ligne en attaquant. Cet article montre comment les transformers encodent les concepts dans leurs activations internes et comment les détecter.

appledb_rs, un outil d'aide à la recherche sur plateformes Apple

25/09/2025 Au fil des années, la recherche sur les plateformes Apple s’est considérablement complexifiée, en grande partie à cause des nombreuses contre-mesures déployées au fil du temps par la marque à la pomme. Pour répondre à ce défi durant nos missions sur ces plateformes, nous avons développé appledb_rs: un outil open‑source (https://github.com/synacktiv/appledb_rs) qui extrait les données des fichiers IPSW (archive contenant le firmware Apple) et les organise de manière structurée, facilitant ainsi leur exploration et leur analyse.

Diving into ADB protocol internals (2/2)

16/12/2024 Our previous article laid the groundwork for understanding the ADB protocol and its usage scenarios. It primarily focused on the TCP/IP communication between the ADB Client and the ADB Server. However, this still required at this point an intermediate server to bridge our client and the Android device. In this article, we'll dive into the message protocol between ADB Server and adbd, with the goal of improving our Rust client library with capacity to fully interact with a device, eliminating the need for system dependency installatio...

Automated Network Security with Rust: Detecting and Blocking Port Scanners

06/12/2024 Did you ever wonder how IDS/IPS like Snort or Suricata were able to interact with the network stack of the Linux kernel ? Do you also happen to like Rust ? Well dear reader, this article is for you !

Diving into ADB protocol internals (1/2)

12/09/2024 For those having experience working on Android devices, you may already be familiar with a useful tool called adb. This tool is invaluable for debugging, offering a unified way to execute shell commands, transfer files, install APKs, and much more. In this first blogpost, we will explore its underlying protocol between client and server and introduce a Rust crate called adb_client implementing it.

Battle of the parsers: PEG vs combinators

25/07/2024 In this article we will compare two parsing strategies : PEG based and combinators based, from a developer's perspective, to parse Strace output for the SHH (Systemd Hardening Helper) Rust project.

systemd hardening made easy with SHH

07/11/2023 Introducing SHH, Systemd Hardening Helper, a tool written in Rust to automatically build a set of hardening options for a service using runtime profiling.

Building a io_uring based network scanner in Rust

20/01/2023 Using the recent io_uring Linux kernel API to build a fast and modular network scanner in the Rust language
