Join us in our journey into modern Android's Data Encryption at rest, in which we study how it works and assess how resistant it is against attackers having access to a range of high end software vulnerabilities.

This article is about greybox fuzzing of userland targets that can be encountered in Android using AFL++ and its Frida mode. We also discuss how to target JNI functions, to test the native features invoked by Java code.

Following our presentation at Black Hat USA, in this blog post we provide some details on CVE-2022-20233, the latest vulnerability we found on Titan M, and how we exploited it to obtain code execution on the chip.

In this blog post, we present a new vulnerability dataset composed of thousands of vulnerabilities aimed at helping security practitioners to develop, test and enhance their tools. Unlike others, this dataset contains both the vulnerable and fixed states with source data.

When analyzing an Android application, we often end up playing with the Smali intermediate representation... Way more human readable than the binary DEX code itself, but still not that user friendly. This blog post gives some guidelines on how to read Smali, and start writing you own Smali code!

A quick introduction to Android Emuroot, a Python script that allows to get root privileges on the fly on an Android Virtual Device (AVD). It explains the reverse engineering steps needed for the script to work with recent AVDs and provides a preview of specific Linux kernel structures in memory.

This blog post introduces the release 0.8.0 of QBDI.

This blog post dives into how to get a better understanding of an Android native function by taking full advantage of both Frida and QBDI.

This third article from the Samsung's TrustZone series details some vulnerabilities that were found and how they were exploited to obtain code execution in EL3.

In March 2020, Google patched a critical vulnerability affecting many MediaTek based devices. This vulnerability had been known by MediaTek since April 2019, and later exploited in the wild! In this post, we give some details about this vulnerability and see how we can use it to achieve kernel memory reads and writes.
