    Rocketry

    Rocketry

    Modern scheduling library for Python

    Scheduler to power your Python apps. Rocketry is a modern statement-based scheduling framework for Python. It is simple, clean and extensive. It is suitable for small and big projects. Unlike the alternatives, Rocketry's scheduler is statement-based. Rocketry natively supports the same scheduling strategies as the other options, including cron and task pipelining, but it can also be arbitrarily extended using custom scheduling statements. Rocketry is suitable for quick automation projects and for larger-scale applications. It does not make assumptions of your project structure. In addition, Rocketry is very easy to use. It does not require complex setup but it can be used for bigger applications. It has a lot of options to fine-tune and a lot of features to support various needs. Rocketry is designed to be modified and it suits well as the engine for autonomous applications. It is the automation back-end that sets your applications alive.

    SILENTTRINITY

    SILENTTRINITY

    An asynchronous, collaborative post-exploitation agent

    SILENTTRINITY is a modern post-exploitation framework built around asynchronous, collaborative, and multi-server workflows for authorized security operations. It is powered by Python 3 and .NET’s Dynamic Language Runtime, using the author’s Bring Your Own Interpreter concept to dynamically evaluate tasks through embedded .NET scripting languages. The framework was designed to bring back some of the flexibility associated with PowerShell-style operations without directly relying on PowerShell. Its architecture supports multiple users, multiple teamservers, real-time communication, and a modern command-line interface. It also includes modular listeners, modules, stagers, and communication channels, allowing operators to adapt the framework to different lab or assessment needs. Because it is a C2 and post-exploitation framework, it is appropriate only for authorized red-team, training, and research environments.

    SSRFmap

    SSRFmap

    Automatic SSRF fuzzer and exploitation tool

    SSRFmap is a specialized security tool designed to automate the detection and exploitation of Server Side Request Forgery (SSRF) vulnerabilities. It takes as input a Burp request file and a user-specified parameter to fuzz, enabling you to fast-track the identification of SSRF attack surfaces. It includes multiple exploitation “modules” for common SSRF-based attacks or pivoting techniques, such as DNS zone transfers, MySQL/Postgres command execution, Docker API info leaks, and network scans. Because SSRF often leads to lateral movement or internal network access, SSRFmap is especially useful for red-teamers and pentesters who want to explore chains rather than just the vulnerability surface. The repository also demonstrates a pragmatic mindset; rather than just “find SSRF”, it tries to “exploit SSRF” for impact, helping security testers build full end-to-end workflows.

    SeleniumBase

    SeleniumBase

    A framework for browser automation and testing with Selenium

    SeleniumBase automatically handles common WebDriver actions such as launching web browsers before tests, saving screenshots during failures, and closing web browsers after tests. SeleniumBase lets you customize test runs from the command line. SeleniumBase uses simple syntax for commands. pytest includes automatic test discovery. If you don't specify a specific file or folder to run, pytest will automatically search through all subdirectories for tests to run. No More Flaky Tests! SeleniumBase methods automatically wait for page elements to finish loading before interacting with them (up to a timeout limit). This means you no longer need random time.sleep() statements in your scripts. SeleniumBase includes an automated/manual hybrid solution called MasterQA, which speeds up manual testing by having automation perform all the browser actions while the manual tester handles validation.

    SharPyShell

    SharPyShell

    Tiny and obfuscated ASP.NET webshell for C# web applications

    SharPyShell is a tiny and obfuscated ASP.NET web shell that executes commands received by an encrypted channel compiling them in memory at runtime. SharPyShell supports only C# web applications that run on .NET Framework >= 2.0. SharPyShell is a post-exploitation framework written in Python. The main aim of this framework is to provide the penetration tester with a series of tools to ease the post-exploitation phase once exploitation has been successful against an IIS webserver. This tool is not intended as a replacement for the frameworks for C2 Server (i.e. Meterpreter, Empire, etc..) but this should be used when you land on a fully restricted server where inbound and outbound connections are very limited. In this framework, you will have all the tools needed to privesc, net discovery, and lateral movement as you are typing behind the cmd of the target server.
