OWASP Juice Shop
Probably the most modern and sophisticated insecure web application
OWASP Juice Shop is probably the most modern and sophisticated insecure web application! It can be used in security trainings, awareness demos, CTFs and as a guinea pig for security tools! Juice Shop encompasses vulnerabilities from the entire OWASP Top Ten along with many other security flaws found in real-world applications! Juice Shop is written in Node.js, Express and Angular. It was the first application written entirely in JavaScript listed in the OWASP VWA Directory. The application contains a vast number of hacking challenges of varying difficulty where the user is supposed to exploit the underlying vulnerabilities. The hacking progress is tracked on a score board. Finding this score board is actually one of the (easy) challenges! Apart from the hacker and awareness training use case, pentesting proxies or security scanners can use Juice Shop as a "guinea pig"-application to check how well their tools cope with JavaScript-heavy application frontends and REST APIs.">

The sandbox libraries (libsandbox & pysandbox) are an open-source suite of software components for C/C++ and Python developers to create automated profiling tools and watchdog programs. The API's are designed for executing and instrumenting simple (single process) tasks, featuring policy-based behavioral auditing, resource quota, and statistics collecting. The sandbox libraries were originally designed and utilized as the core security module of a full-fledged online judge system for ACM/ICPC training. They have since then evolved into a general-purpose tool for binary program testing, profiling, and security restriction. The sandbox libraries are currently maintained by the OpenJudge Alliance (http://openjudge.net/) as a standalone, open-source project to facilitate various assignment grading solutions for IT/CS education. See project page at https://github.com/openjudge/sandbox for details.

GameOver
Training and educating about the web security
About GameOver: Project GameOver was started with the objective of training and educating newbies about the basics of web security and educate them about the common web attacks and help them understand how they work. GameOver has been broken down into two sections. Section 1 consists of special web applications that are designed especially to teach the basics of Web Security. This seciton will cover XSS CSRF RFI & LFI BruteForce Authentication Directory/Path traversal Command execution SQL injection Section 2 is a collection of dileberately insecure Web applications. This section provides a legal platform to test your skills and to try and exploit the vulnerabilities and sharpen your skills before you pentest live sites. We would advice newbies to try and exploit these web applications. These applications provide real life environments and will boost their confidence. -

Ray Tracing in One Weekend Book Series
The Ray Tracing in One Weekend series of books
The Ray Tracing in One Weekend series of books are now available to the public for free online. They are now released under the CC0 license. This means that they are as close to public domain as we can get. (While that also frees you from the requirement of providing attribution, it would help the overall project if you could point back to this web site as a service to other users.) These books are formatted for printing directly from your browser, where you can also (on most browsers) save them as PDF. In Ray Tracing in One Weekend, you will build a simple brute-force path tracer. Continuing with Ray Tracing: The Next Week, you will add textures, volumes (like fog), rectangles, instances, lights, and support for lots of objects using a bounding volume hierarchy (BVH). Finally, with Ray Tracing: The Rest Of Your Life, we'll dive into the math of creating a very serious ray tracer. -

Netviz
Netviz is a Python app designed to monitor devices on the user's LAN.
Netviz (short for NETwork VIsualiZer) is a Python program I cobbled together for a user to monitor devices on the user's LAN or a small section of the Internet. Essentially, it's a pretty interface for information on the MAC addresses and IPs of those devices. The range to search can be set either by the boundaries of the user's LAN using the "Find Range" button or through user-typed IPs. Also, there is a list of tracked MACs. If any of these tracked MACs appears on the LAN, the program shows the IP of this MAC. -

SteghideGUI
Steghide GUI is perfect C++/Qt app for embedding and extracting data
Steghide is a steganography program that is able to hide data in various kinds of image- and audio-files. The color- respectivly sample-frequencies are not changed thus making the embedding resistant against first-order statistical tests. SteghideGUI is Qt GUI with various features. It supports steganography capacity counter (also supports UTF8 and compression). It serves like a educational demonstration of embedding process. You can also view cover and stegogram in custom image viewer. -

ISC - The ISAAC Stream Cipher
ISC lets you encrypt & decrypt text and files of any type up to 4GB
ISAAC is a cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It was developed by Bob Jenkins from 1993-1996 and placed in the Public Domain. ISAAC is fast - especially when optimised - and portable to most architectures in nearly all programming and scripting languages. After more than 20 years of existence ISAAC has not been broken, and the little program you have here allows you to use it to encrypt and decrypt text of arbitrary length, files of any type, on a key-phrase of any complexity. ISC is a symmetric key encryption system, which means that both the sender and recipient of a message must possess the key. -
