toxy - Hackable HTTP proxy for resiliency testing and simulated network conditions

•    Javascript

---

Hackable HTTP proxy to simulate server failure scenarios, resiliency and unexpected network conditions, built for node.js.It was mainly designed for failure resistance testing, when toxy becomes particularly useful in order to cover fault tolerance and resiliency capabilities of a system, especially in disruption-tolerant networks and service-oriented architectures, where toxy may act as MitM proxy among services in order to inject failure.

DifferentialEquations.jl - Julia suite for high-performance solvers of differential equations

•    Julia

---

The well-optimized DifferentialEquations solvers benchmark as the some of the fastest implementations, using classic algorithms and ones from recent research which routinely outperform the "standard" C/Fortran methods, and include algorithms optimized for high-precision and HPC applications. At the same time, it wraps the classic C/Fortran methods, making it easy to switch over to them whenever necessary. It integrates with the Julia package sphere, for example using Juno's progress meter, automatic plotting, built-in interpolations, and wraps other differential equation solvers so that many different methods for solving the equations can be accessed by simply switching a keyword argument. It utilizes Julia's generality to be able to solve problems specified with arbitrary number types (types with units like Unitful, and arbitrary precision numbers like BigFloats and ArbFloats), arbitrary sized arrays (ODEs on matrices), and more. This gives a powerful mixture of speed and productivity features to help you solve and analyze your differential equations faster. For information on using the package, see the stable documentation. Use the latest documentation for the version of the documentation which contains the un-released features.

metta - An information security preparedness tool to do adversarial simulation.

•    Python

---

Metta is an information security preparedness tool. This project uses Redis/Celery, python, and vagrant with virtualbox to do adversarial simulation. This allows you to test (mostly) your host based instrumentation but may also allow you to test any network based detection and controls depending on how you set up your vagrants.

firmadyne - System for emulation and dynamic analysis of Linux-based firmware

•    Shell

---

We have also written the following three basic automated analyses using the FIRMADYNE system. In our 2016 Network and Distributed System Security Symposium (NDSS) paper, titled Towards Automated Dynamic Analysis for Linux-based Embedded Firmware, we evaluated the FIRMADYNE system over a dataset of 23,035 firmware images, of which we were able to extract 9,486. Using 60 exploits from the Metasploit Framework, and 14 previously-unknown vulnerabilities that we discovered, we showed that 846 out of 1,971 (43%) firmware images were vulnerable to at least one exploit, which we estimate to affect 89+ different products. For more details, refer to our paper linked above.
