Is LLM-assisted reverse engineering making obfuscation pointless? We spent a couple of weeks trying to find out, by handing sandboxed agents a series of progressively hardened AArch64 binaries and one prompt: recover the hidden strings inside. This post walks through what the agent actually did, three ways our experiment fell apart, and what those failures suggest about designing protections that hold against automated analysis.

This article describes the main software protection techniques used in Android applications, organized around a taxonomy covering environment checks, obfuscation, and program loading abuse. It presents the results of a large-scale analysis of nearly 2.5 million Android apps, studying how widely these protections are adopted across different markets, app categories, and malware samples.

How one Commit Broke Obfuscation: A blog post exploring the role of compilers and optimizations in the field of obfuscation and de-obfuscation.

In this article I describe Java bytecode obfuscation, using one of the challenges I did in 2023 as part of the interviews with Quarkslab for the position of Java compiler engineer in QShield.

This blog post demonstrates through an example how the Epona obfuscating compiler, from the Epona Application Protection Suite, achieves the challenge of facilitating the everyday experience of its users while enabling better obfuscation schemes trade-offs.

In this article I describe my two-months summer internship project at Quarkslab: obfuscating Java bytecode using the [Epona] Code Obfuscator. This article explains our approach, its advantages and limitations.

What happens if one builds up on the Spectre vulnerability to implement a convoluted version of memcpy? From an obfuscator point-of-view, it unleashes a wide range of opportunities, which turn a definite bug into a fun[nk]y feature.

Some experiments to mistreat the Triton concolic execution framework through simple forged C programs.
