We discovered several vulnerabilities impacting the boot chain of several Samsung devices. Chained together, they allow us to execute code in the bootloader, get root access on Android with persistency, and finally leak anything from the Secure World's memory including the Android Keystore keys.

This is a writeup of a heap pwn challenge at HitconCTF Qualifiers 2024, which explains some glibc malloc internals and some heap exploitation tricks that can be used for getting a shell!

In this blog post, we present a new vulnerability on the Gecko Bootloader from Silicon Labs more precisely inside the OTA parser.

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 blog post presents a post-exploitation approach to inject code into KeePass without process injection. It is performed by abusing the cache resulting from the compilation of PLGX plugin.

This article introduces a kind of eBPF program that may be used to monitor userspace programs. It first introduces you to eBPF and uprobes and then explores the flaws that we found in uprobes.

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.

This blog post analyzes the vulnerability known as "Bad Neighbor" or CVE-2020-16898, a stack-based buffer overflow in the IPv6 stack of Windows, which can be remotely triggered by means of a malformed Router Advertisement packet.

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.
