Gobuster
Directory/File, DNS and VHost busting tool written in Go
Gobuster is a tool used to brute-force. This project is born out of the necessity to have something that didn't have a fat Java GUI (console FTW), something that did not do recursive brute force, something that allowed me to brute force folders and multiple extensions at once, something that compiled to native on multiple platforms, something that was faster than an interpreted script (such as Python), and something that didn't require a runtime. Provides several modes, like the classic directory brute-forcing mode, DNS subdomain brute-forcing mode, the mode that enumerates open S3 buckets and looks for existence and bucket listings, and the virtual host brute-forcing mode (not the same as DNS!). Since this tool is written in Go you need to install the Go language/compiler/etc. Full details of installation and set up can be found on the Go language website. Once installed you have two options. You need at least go 1.16.0 to compile gobuster. -

Tamper Dev
Extension that allows you to intercept and edit HTTP/HTTPS requests
If you are a developer, you can use Tamper Dev to debug your websites, or if you are a pentester, you can use it to search for security vulnerabilities by inspecting the HTTP traffic from your browser. Unlike most other extensions, Tamper Dev allows you to intercept, inspect and modify the requests before they are sent to the server. This extension provides functionality similar to Burp Proxy, MITM Proxy, OWASP ZAP, Tamper Data, and Postman Proxy, but without the need of additional software, with full support of HTTPS connections, and trivial to set-up (just install). -

It's the ideal tool for penetration testers and software developers, able to debug, test, and make privacy measurements. It can intercept, inspect, modify and replay web traffic, and can even prettify and decode a variety of message types. Its web-based interface mitmweb gives you a similar experience as Chrome's DevTools, with the addition of features like request interception and replay. Its command-line version mitmdump allows you to write powerful addons and script mitmproxy so it can automatically modify messages, redirect traffic, and perform many other custom commands. -

Retire.js
Scanner detecting the use of JavaScript libraries
There is a plethora of JavaScript libraries for use on the web and in node.js apps out there. This greatly simplifies, but we need to stay updated on security fixes. "Using Components with Known Vulnerabilities" is now a part of the OWASP Top 10 and insecure libraries can pose a huge risk for your web app. The goal of Retire.js is to help you detect the use of versions with known vulnerabilities. Scan a web app or node app for use of vulnerable JavaScript libraries and/or node modules. grunt-retire scans your grunt-enabled app for use of vulnerable JavaScript libraries and/or node modules. Scans visited sites for references to insecure libraries and puts warnings in the developer console. An icon on the address bar displays will also indicate if vulnerable libraries were loaded. Retire.js has been adapted as a plugin for the penetration testing tools Burp and OWASP ZAP. -

proxy.py
Utilize all available CPU cores for accepting new client connections
proxy.py is made with performance in mind. By default, proxy.py will try to utilize all available CPU cores to it for accepting new client connections. This is achieved by starting AcceptorPool which listens on configured server port. Then, AcceptorPool starts Acceptor processes (--num-acceptors) to accept incoming client connections. Alongside, if --threadless is enabled, ThreadlessPool is setup which starts Threadless processes (--num-workers) to handle the incoming client connections. Each Acceptor process delegates the accepted client connection to a threadless process via Work class. Currently, HttpProtocolHandler is the default work class. HttpProtocolHandler simply assumes that incoming clients will follow HTTP specification. Specific HTTP proxy and HTTP server implementations are written as plugins of HttpProtocolHandler. -

CloudBrute
Awesome cloud enumerator
A tool to find a company (target) infrastructure, files, and apps on the top cloud providers (Amazon, Google, Microsoft, DigitalOcean, Alibaba, Vultr, Linode). The outcome is useful for bug bounty hunters, red teamers, and penetration testers alike. While working on HunterSuite, and as part of the job, we are always thinking of something we can automate to make black-box security testing easier. We discussed this idea of creating a multiple platform cloud brute-force hunter.mainly to find open buckets, apps, and databases hosted on the clouds and possibly app behind proxy servers. Cloud detection (IPINFO API and Source Code) Supports all major providers. Black-Box (unauthenticated). Fast (concurrent), modular and easily customizable, cross Platform (windows, linux, mac), user-agent randomization, proxy randomization (HTTP, Socks5). -

BeEF
The browser exploitation framework project
BeEF is short for The Browser Exploitation Framework. It is a penetration testing tool that focuses on the web browser. Amid growing concerns about web-borne attacks against clients, including mobile clients, BeEF allows the professional penetration tester to assess the actual security posture of a target environment by using client-side attack vectors. Unlike other security frameworks, BeEF looks past the hardened network perimeter and client system, and examines exploitability within the context of the one open door: the web browser. BeEF will hook one or more web browsers and use them as beachheads for launching directed command modules and further attacks against the system from within the browser context. -
