    pty

    pty

    PTY interface for Go

    Pty is a Go package for using unix pseudo-terminals. Note that the examples are for demonstration purpose only, to showcase how to use the library. They are not meant to be used in any kind of production environment. Start assigns a pseudo-terminal tty os.File to c.Stdin, c.Stdout, and c.Stderr, calls c.Start, and returns the File of the tty's corresponding pty. InheritSize applies the terminal size of pty to tty. This should be run in a signal handler for syscall.SIGWINCH to automatically resize the tty when the pty receives a window size change notification.

    picocli

    picocli

    Framework for building GraalVM-enabled command line apps

    Picocli is a one-file framework for creating Java command-line applications with almost zero code. It supports a variety of command-line syntax styles including POSIX, GNU, MS-DOS and more. It generates highly customizable usage help messages that use ANSI colors and styles to contrast important elements and reduce the cognitive load on the user. Picocli-based applications can have command line TAB completion showing available options, option parameters, and subcommands, for any level of nested subcommands. Picocli-based applications can be ahead-of-time compiled to a GraalVM native image, with extremely fast startup time and lower memory requirements, which can be distributed as a single executable file. Picocli generates beautiful documentation for your application (HTML, PDF and Unix man pages). Another distinguishing feature of picocli is how it aims to let users run picocli-based applications without requiring picocli as an external dependency.

    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.
