The OSTIF collaborated with Quarkslab to conduct a security audit of Paramiko, a pure-Python implementation of SSHv2 that provides both client- and server-side functionality. Given the sensitivity and importance of the target, the review focused not only on Paramiko itself but also on its dependencies. The assessment covered its interaction with rust-openssl bindings, the use of secure entropy sources, adherence to constant-time requirements, as well as code quality, testing practices, and the CI/CD pipeline, with the goal of identifying opportunities for further hardening.

This blog post explores Entra ID applications, the complexities of auditing application permissions in Microsoft Entra ID, highlighting hidden risks and pitfalls. It introduces Quarkslab's QAZPT tool, designed to compute and visualize effective permissions in an Entra ID tenant, providing insights into the full picture of permissions and inheritance paths.

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

Since its initial released in December 2023, many people have used and built tools around the BSIM feature of Ghidra but up to this date its internals were unknown. This post brings some light on how BSIM works, theoretically and in it's C++ implementation.

From hardware analysis to OSINT: how we retrieved information about a BYD car crash by analyzing the TCU embedded memory.

Exploitation of an arbitrary directory deletion via symlink following in the antivirus Intego.

In this blog post we present SightHouse, an open-source tool designed to assist reverse engineers by retrieving information and metadata from programs and identifying similar functions already known from other libraries, binaries or any other source codes that can be found online.

In this blog, we present how QBDI and TritonDSE can be used to attack a complex C++ binary implementing a VM.

Deep dive into Web Application Firewall (WAF) bypasses, from misconfiguration exploitation to crafting obfuscated payloads. We show the impact of the parsing discrepancy between how a WAF reads a request and how a backend executes it. It is not a bug, it is a feature.

This blog post dives into the most common classes of macOS Local Privilege Escalation vulnerabilities, from insecure XPC communications and time-of-check to time-of-use (TOCTOU) Race Conditions to a range of implementation and configuration oversights. We will explore how attackers can exploit these weaknesses to escalate privileges, and highlight real-world examples to illustrate recurring patterns. This post ends the series on Intego products on macOS by revealing vulnerabilities that can lead to Local Privilege Escalation, as well as a surprise bonus.
