Luakit
Fast, small, webkit based browser framework extensible by Lua
Luakit is a highly configurable browser framework based on the WebKit web content engine and the GTK+ toolkit. It is very fast, extensible with Lua, and licensed under the GNU GPLv3 license. It is primarily targeted at power users, developers and anyone who wants to have fine-grained control over their web browser’s behavior and interface. While switching to the WebKit 2 API means a vastly improved security situation, not all distributions of Linux package the most up-to-date version of WebKitGTK+, and several package very outdated versions that have many known vulnerabilities. As of September 2019, Arch, Debian, Fedora, Gentoo, and Ubuntu all have the latest version of WebKitGTK+, but OpenSUSE ships an outdated and vulnerable version in their stable channel. If you use Luakit for browsing, it is your responsibility to ensure that your distribution packages an up-to-date version of WebKitGTK+! -

Privaxy
Privaxy is the next generation tracker and advertisement blocker
Next generation tracker and advertisement blocker. Privaxy is a MITM HTTP(s) proxy that sits in between HTTP(s) talking applications, such as a web browser and HTTP servers, such as those serving websites. By establishing a two-way tunnel between both ends, Privaxy is able to block network requests based on URL patterns and to inject scripts as well as styles into HTML documents. Operating at a lower level, Privaxy is both more efficient as well as more streamlined than browser add-on-based blockers. A single instance of Privaxy on a small virtual machine, server or even, on the same computer as the traffic is originating from, can filter thousands of requests per second while requiring a very small amount of memory. -

Shennina
Automating Host Exploitation with AI
Shennina is an automated host exploitation framework. The mission of the project is to fully automate the scanning, vulnerability scanning/analysis, and exploitation using Artificial Intelligence. Shennina is integrated with Metasploit and Nmap for performing the attacks, as well as being integrated with an in-house Command-and-Control Server for exfiltrating data from compromised machines automatically. Shennina scans a set of input targets for available network services, uses its AI engine to identify recommended exploits for the attacks, and then attempts to test and attack the targets. If the attack succeeds, Shennina proceeds with the post-exploitation phase. The AI engine is initially trained against live targets to learn reliable exploits against remote services. Shennina also supports a "Heuristics" mode for identfying recommended exploits. -

Tsunami
Network security scanner for detecting severity vulnerabilities
Tsunami is a general purpose network security scanner with an extensible plugin system for detecting high severity vulnerabilities with high confidence. When security vulnerabilities or misconfigurations are actively exploited by attackers, organizations need to react quickly in order to protect potentially vulnerable assets. As attackers increasingly invest in automation, the time window to react to a newly released, high severity vulnerability is usually measured in hours. This poses a significant challenge for large organizations with thousands or even millions of internet-connected systems. In such hyperscale environments, security vulnerabilities must be detected and ideally remediated in a fully automated fashion. To do so, information security teams need to have the ability to implement and roll out detectors for novel security issues at scale in a very short amount of time. Furthermore, it is important that the detection quality is consistently very high. -

UFW Docker
To fix the Docker and UFW security flaw without disabling iptables
UFW is a popular iptables front end on Ubuntu that makes it easy to manage firewall rules. But when Docker is installed, Docker bypasses the UFW rules and the published ports can be accessed from outside. Almost all of these solutions are similar. It requires disabling docker's iptables function first, but this also means that we give up docker's network management function. This causes containers will not be able to access the external network. It is also mentioned in some articles that you can manually add some rules in the UFW configuration file, such as -A POSTROUTING! -o docker0 -s 172.17.0.0/16 -j MASQUERADE. But this only allows containers that belong to network 172.17.0.0/16 can access outside. If we create a new docker network, we must manually add similar iptables rules for the new network. -

VX-API
Collection of various malicious functionality
VX-API is a research-oriented collection of Windows-focused code that demonstrates low-level techniques commonly studied in malware analysis and red-team development. It is organized as a Visual Studio solution so related functions and dependencies can be explored together. The repository covers areas such as anti-debugging, cryptographic helpers, fingerprinting, process creation, process injection, networking, library loading, and string handling. It also includes examples involving shellcode execution, privilege-related behavior, and Windows internals. Individual components can be examined separately rather than used as one monolithic program. Because the code can enable harmful behavior, it is best handled only in isolated, authorized security research environments. -

XRAY
XRay for recon, mapping and OSINT gathering from public networks
XRAY is a modular security toolset that helps developers and security professionals analyze, fuzz, and test web applications, protocols, and network services for vulnerabilities. It provides a framework for writing and executing inspection modules that can parse structured data (JSON, XML, HTML), traverse graphs of endpoints, and perform intelligent probing guided by discovered surface area. XRay is typically used as a reconnaissance and vulnerability discovery engine in red-team or app-security workflows: it leverages extensible plugins to adapt to different protocols, inject payloads, and detect common bug classes such as injection flaws, misconfigurations, and unsafe endpoints. The modular architecture means users can customize or extend the engine with new analyzers, fuzzers, or output formats tailored to specific testing environments. Rather than being a “one-size-fits-all” black box scanner, XRAY encourages interactive exploration and integrates with other tooling. -

25
gitGraber
Real-time GitHub monitor that detects leaked API keys and secrets
gitGraber is a Python-based security tool designed to monitor GitHub in real time to detect exposed sensitive information in publicly indexed repositories. It scans recently indexed files on GitHub and searches for patterns that may indicate leaked credentials, API keys, or other confidential data used by popular online services. Instead of analyzing the full history of repositories, the tool focuses on newly indexed content, allowing security researchers and bug bounty hunters to quickly identify fresh leaks as they appear. gitGraber uses carefully crafted regular expressions to detect tokens and secrets associated with platforms such as AWS, Google, PayPal, Twitter, Stripe, and many others. When a potential leak is discovered, the tool can notify users through messaging platforms or display results directly in the command line. This approach helps organizations and security professionals monitor potential exposures.
