    TurboVNC

    TurboVNC

    High-speed, 3D-friendly, TightVNC-compatible remote desktop software

    TurboVNC is a high-performance, enterprise-quality version of VNC based on TightVNC, TigerVNC, and X.org. It contains a variant of Tight encoding that is tuned for maximum performance and compression with 3D applications (VirtualGL), video, and other image-intensive workloads. TurboVNC, in combination with VirtualGL, provides a complete solution for remotely displaying 3D applications with interactive performance. TurboVNC's high-speed encoding methods have been adopted by TigerVNC and libvncserver, and TurboVNC is also compatible with any other TightVNC derivative. TurboVNC forked from TightVNC in 2004 and still covers all of the TightVNC 1.3.x features, but TurboVNC contains numerous feature enhancements and bug fixes relative to TightVNC, and it compresses 3D and video workloads much better than TightVNC while using generally only 5-20% of the CPU time of the latter. Using non-default settings, TurboVNC can also be made to compress 2D workloads as "tightly" as TightVNC.

    VirtualBox

    VirtualBox

    Virtualization software for x86_64 hardware

    VirtualBox is a powerful open-source full virtualization software that allows a user to run one or more “guest” operating systems simultaneously inside “virtual machines” on a single physical “host” machine. It supports a wide variety of host platforms (Linux, Windows, macOS, Solaris, etc.) and guest OSes, enabling, for example, running Linux on a Windows PC, running Windows Server on a Linux host, or even legacy OSes in a controlled environment. This flexibility makes VirtualBox ideal for developers, testers, sysadmins, or hobbyists who need different OS environments, want to test software across systems, or need isolation for development, sandboxing, or security experiments. VirtualBox offers both a user-friendly GUI as well as a command-line interface and headless mode, making it useful for desktop usage as well as server or automated environments.

    bWAPP

    an extremely buggy web app !

    bWAPP, or a buggy web application, is a free and open source deliberately insecure web application. bWAPP helps security enthusiasts, developers and students to discover and to prevent web vulnerabilities. bWAPP prepares one to conduct successful penetration testing and ethical hacking projects. What makes bWAPP so unique? Well, it has over 100 web bugs! It covers all major known web vulnerabilities, including all risks from the OWASP Top 10 project. The focus is not just on one specific issue... bWAPP is covering a wide range of vulnerabilities! bWAPP is a PHP application that uses a MySQL database. It can be hosted on Linux/Windows with Apache/IIS and MySQL. It is supported on WAMP or XAMPP. Another possibility is to download bee-box, a custom VM pre-installed with bWAPP. This project is part of the ITSEC GAMES project. You can find more about the ITSEC GAMES and bWAPP projects on our blog. For security-testing and educational purposes only! Cheers Malik Mesellem

    Easy GPU PV

    Easy GPU PV

    A Project dedicated to making GPU Partitioning on Windows easier

    Easy-GPU-PV is an open-source project that automates the relatively complex steps required to set up GPU Paravirtualization (GPU-PV) on Windows Hyper-V, letting you partition a physical GPU and assign slices to virtual machines for low-latency remote use. It creates and installs a Windows VM, copies the necessary GPU-PV driver files into the VM, and helps install Parsec (an ultra-low-latency remote-desktop client) so you can connect to the VM at high framerates. The repo is practical and script-driven: the author provides PowerShell scripts (PreChecks.ps1, CopyFilesToVM.ps1, Update-VMGpuPartitionDriver.ps1, etc.) plus configuration values and an unattended install template to minimize manual steps. The README documents hardware and OS prerequisites (Windows 10 20H1+/Windows 11 Pro/Enterprise/Education, matched host/VM versions, virtualization and Hyper-V enabled, recent GPU drivers, and supported GPUs.

    WireMock

    WireMock

    A tool for mocking HTTP services

    HTTP response stubbing, matchable on URL, header and body content patterns. Request verification, runs in unit tests, as a standalone process or as a WAR app. Configurable via a fluent Java API, JSON files and JSON over HTTP. Record/playback of stubs, fault injection, per-request conditional proxying, browser proxying for request inspection and replacement. Stateful behavior simulation and configurable response delays. Mock your APIs for fast, robust and comprehensive testing. WireMock is a simulator for HTTP-based APIs. Some might consider it a service virtualization tool or a mock server. It enables you to stay productive when an API you depend on doesn't exist or isn't complete. It supports testing of edge cases and failure modes that the real API won't reliably produce. And because it's fast it can reduce your build time from hours down to minutes.

    Instructions: After starting this VM, enable the Play Store app, by clicking the Settings -> Apps -> Play Store -> Enable. Then, Launch Play Store App, by clicking the 3 vertical dots icon, at the bottom of desktop. Then download whatever app is needed from the Play Store. Quickly, Cancel any automatic downloads of Play Store app ( itself ), from the notification drawer, as this will prevent it from its future working. Disable the Play Store app, after your other app installs are completed. Increase CPU Count and Memory in VM's Settings, as required, for better performance. If you are very new to virtual machines, then please refer the Wiki Page for its setup instructions, for all major operating systems.
