LiquidHaskell
Liquid Types For Haskell
This is the development site of the LiquidHaskell formal verification tool. If you're a LiquidHaskell user (or just curious), you probably want to go to the documentation website instead. LiquidHaskell (LH) refines Haskell's types with logical predicates that let you enforce important properties at compile time. LH warns you that head is not total as it is missing the case for [] and checks that it is total on NonEmpty lists. The input contract propagates to uses of head which are verified by ensuring the arguments are NonEmpty. LH lets you avoid off-by-one errors that can lead to crashes or buffer overflows. Dependent contracts let you specify, e.g. that dotProduct requires equal-sized vectors. LH checks that functions terminate and so warns about the infinite recursion due to the missing case in fib. -

Notary
Have trust over arbitrary collections of data
Notary is a project that aims to make the internet more secure by simplifying how people publish and verify content. The Notary project is made up of a server and a client made to run and interact with trusted collections. Instead of relying on TLS to secure communications with a web server that's susceptible to malicious content, publishers can sign their content offline using secure keys with Notary. Once ready to make the content available, publishers can then push their signed trusted collection to a Notary Server. Consumers can then communicate with any Notary server or (insecure) mirror through the publisher's public key acquired through a secure channel. This key will be what determines the validity and integrity of the received content. -

Ockam
Orchestrate end-to-end encryption, mutual authentication
Ockam is a suite of open source tools, programming libraries, and managed cloud services to orchestrate end-to-end encryption, mutual authentication, key management, credential management, and authorization policy enforcement – at massive scale. Modern applications are distributed and have an unwieldy number of interconnections that must trustfully exchange data. To build trust for data-in-motion, applications need end-to-end guarantees of data authenticity, integrity, and confidentiality. To be private and secure by-design, applications must have granular control over every trust and access decision. Ockam allows you to add these controls and guarantees to any application. We are passionate about making powerful cryptographic and messaging protocols simple and safe to use for millions of builders. Create a mutually authenticated and end-to-end encrypted secure channel between two Ockam nodes. -

Offensive Web Testing Framework
Offensive Web Testing Framework (OWTF), is a framework
OWASP OWTF is a project focused on penetration testing efficiency and alignment of security tests to security standards like the OWASP Testing Guide (v3 and v4), the OWASP Top 10, PTES and NIST so that pentesters will have more time to see the big picture and think out of the box. More efficiently find, verify and combine vulnerabilities. Have time to investigate complex vulnerabilities like business logic/architectural flaws or virtual hosting sessions. Perform more tactical/targeted fuzzing on seemingly risky areas. Demonstrate true impact despite the short timeframes we are typically given to test. The tool is highly configurable and anybody can trivially create simple plugins or add new tests in the configuration files without having any development experience. OWTF is developed on KaliLinux and macOS but it is made for Kali Linux (or other Debian derivatives). -

The first all-round open source Web security protection system, more protection than others. OpenWAF is the first fully open source Web application protection system (WAF), based on nginx_lua API analysis of HTTP request information. OpenWAF is composed of two functional engines: behavior analysis engine and rule engine. The rule engine mainly analyzes the individual requests, and the behavior analysis engine is mainly responsible for the tracking of the request information. Rule engine inspired by modsecurity and freewaf(lua-resty-waf), the ModSecurity rules will be implemented using lua. The rule engine can be based on the protocol specification, automatic tools, injection attacks, cross site attacks, information leaks and other security exception request, adding support for dynamic rules, timely repair vulnerabilities. -

Oso
Oso is a batteries-included framework for building authorization
The Oso Library is a batteries-included framework for building authorization in your application. With Oso, you can. Model: Set up common permissions patterns like RBAC and relationships using Oso’s built-in primitives. Extend them however you need with Oso’s declarative policy language, Polar. Filter: Go beyond yes/no authorization questions. Implement authorization over collections too - e.g., “Show me only the records that Juno can see.” Test: Write unit tests over your authorization logic now that you have a single interface for it. Use the debugger or tracing to track down unexpected behavior. Oso lets you write policies to control who can do what in your app. Select different policies below to see how they change the permissions in the sample app on the right. Oso's language libraries can be developed without touching the Rust core, but you will still need the Rust stable toolchain installed in order to build the core. -

Respect\Validation
The most awesome validation engine ever created for PHP
For certain types you can't make comparisons out of the box in PHP but Validation brings support to a few of them. You can also create and use your own rules. To do this, you will need to create a rule and an exception to go with the rule. Each rule must have an Exception to go with it. Exceptions should be named with the name of the rule followed by the word Exception. The process of creating an Exception is similar to creating a rule but there are no methods in the Exception class. On oldest versions of Respect\Validation all validators treat input as optional and accept an empty string input as valid. Even though a useful feature that caused a lot of troubles for our team and neither was an obvious behavior. Also there was some people who likes to accept null as optional value, not only an empty string. -

Slipstream
NAT Slipstreaming allows an attacker to remotely access any TCP/UDP
Slipstream (also referred to as “NAT Slipstreaming”) is a proof-of-concept exploit framework that allows an attacker to remotely access any TCP or UDP service running on a victim machine inside a NAT (behind a router/firewall) simply by tricking the target to visit a malicious website. It works by abusing the NAT’s Application Level Gateway (ALG) logic and connection tracking, combined with browser capabilities like WebRTC, precise packet fragmentation or boundary control, and packet injection techniques. The attack is able to bypass browser port restrictions by fragmenting or massaging packets so that the “exploit payload” lands in a packet boundary that gets parsed by the NAT/ALG as a legitimate protocol packet (e.g. SIP or H.323). Once successful, the NAT/firewall is deceived into opening a “hole” (port forwarding) back to the internal host, enabling the attacker to connect directly to internal services. -

Sudomy
Sudomy is a subdomain enumeration tool to collect subdomains
Sudomy is a subdomain enumeration tool to collect subdomains and analyze domains performing advanced automated reconnaissance (framework). This tool can also be used for OSINT (Open-source intelligence) activities. Easy, light, fast and powerful. Bash script (controller) is available by default in almost all Linux distributions. By using bash script multiprocessing feature, all processors will be utilized optimally. Subdomain enumeration process can be achieved by using active method or passive method. Sudomy utilize Gobuster tools because of its highspeed performance in carrying out DNS Subdomain Bruteforce attack (wildcard support). The wordlist that is used comes from combined SecList (Discover/DNS) lists which contains around 3 million entries. By evaluating and selecting the good third-party sites/resources, the enumeration process can be optimized. More results will be obtained with less time required. -

Supercookie
Browser fingerprinting via favicon!
Supercookie uses favicons to assign a unique identifier to website visitors. Unlike traditional tracking methods, this ID can be stored almost persistently and cannot be easily cleared by the user. The tracking method works even in the browser's incognito mode and is not cleared by flushing the cache, closing the browser or restarting the operating system, using a VPN or installing AdBlockers. The demo of "supercookie", as well as the publication of the source code of this repository, is intended to draw attention to the problem of tracking possibilities using favicons. Modern browsers offer a wide range of features to improve and simplify the user experience. One of these features are the so-called favicons: A favicon is a small (usually 16×16 or 32×32 pixels) logo used by web browsers to brand a website in a recognizable way. Favicons are usually shown by most browsers in the address bar and next to the page's name in a list of bookmarks. -

Wemake Django Template
Bleeding edge django template focused on code quality and security
What this project is all about? The main idea of this project is to provide a fully configured template for django projects, where code quality, testing, documentation, security, and scalability are number one priorities. This template is a result of implementing our processes, it should not be considered as an independent part. When developing this template we had several goals in mind. Development environment should be bootstrapped easily, so we use docker-compose for that. Development should be consistent, so we use strict quality and style checks. Development, testing, and production should have the same environment, so again we develop, test, and run our apps in docker containers. Documentation and codebase are the only sources of truth. This template is oriented on big projects, when there are multiple people working on it for a long period of time.
