Android and the mysteries of dial Codes Extracting dial codes by apk reversing Dial Codes, also called USSD or HMI (Human Machine Interface) codes, are typically used by OEM and carrier to implement some menu. While making baseband researches, those hidden menus was very useful. Today, in this small blogpost, I will described the way…
Ai-assisted Android application reversing Benchmarking Android APK Deobfuscation using Small Local LLMs Tool Overview – Deobfuscate-android-app Android applications are commonly obfuscated before release, especially when they handle sensitive logic such as authentication, license verification, or cryptographic routines. Obfuscation tools like ProGuard and R8 rename classes and methods, remove debug information, and flatten control flows to…
Chatgpt GPT-4 for Bug Bounty, Audit & Pentesting?? He actually found some 0-days I gave some snippets of code (where I already found bugs) to OpenAI GPT-4 and I ask him to find vulnerabilities for me. It’s mind-blowing, it even found some 0 days. You will get access of the complete tutorial with source code, cheat…
🤯 Mind-Blowing examples of OpenAI ChatGPT for Security, Infosec & Hacking It’s just mind-blowing! it’s so impressive that this AI is able to answer such complex subjects as exploitation, reversing, decompilation, etc. The is a huge potential for us in the future to go even faster into learning IT security and hacking by being helped…

Reversing Ewasm smart contracts 101 – EthCC 2020 I just gave a talk/workshop today (03/2020) at EthCC 2020 (Paris – France), about reversing Ewasm (Ethereum flavored WebAssembly) smart contract. In this talk, I briefly introduce WebAssembly concepts , Ewasm ethereum specificity and opcodes/instructions. Secondly, I show how to create Ewasm smart contracts and expose different techniques/tools…
Analysis of Google Keep WebAssembly module Last month, i was at REcon Montreal to give my training about WebAssembly Security and after some discussion people always ask me this question: Is WebAssembly already used in the wild? The answer is of course YES and some WebAssembly modules are potentially running right now in your browser…
