Invoke-PSImage
Encodes a PowerShell script in the pixels of a PNG file
Invoke-PSImage is a PowerShell utility that hides, extracts, and optionally executes PowerShell payloads inside image files using simple steganography techniques. It can embed a script or binary blob into an image (commonly PNG or JPEG) and later recover that payload without leaving a separate file on disk, enabling in-memory execution workflows. The tool offers options for compression and encryption so the embedded content is both smaller and protected by a passphrase when required. It includes helpers to encode a payload into an image, decode an embedded payload back to readable form, and run the extracted content directly from memory to avoid touching disk. Designed as a compact, single-file PowerShell script, it relies on .NET imaging APIs to manipulate pixel data or metadata and to store the payload in a way that survives ordinary file transfers. -

Invoke-TheHash
PowerShell Pass The Hash Utils
Invoke-TheHash is a PowerShell module providing utilities to perform “Pass-the-Hash” style remote operations over WMI and SMB by supplying NTLM hashes instead of plaintext passwords. The project includes multiple scripts/modules (Invoke-WMIExec, Invoke-SMBExec, Invoke-SMBEnum, Invoke-SMBClient, and a wrapper Invoke-TheHash) so operators can choose enumeration, file access, or command execution modes. It uses .NET’s TcpClient for direct SMB/WMI connections and performs authentication by inserting an NTLM hash into the NTLMv2 protocol flow. The module supports both local accounts and domain accounts (via domain parameter), and it accepts either LM:NTLM or pure NTLM format hashes. For command execution, it can create services on remote hosts (SMBExec style) or use WMI class methods. Since it works over network protocols rather than relying on built-in Windows clients, it can bypass some limitations or restrictions in constrained environments. -

Islands Dark
VSCode theme based off the easemate IDE and Jetbrains islands theme
Islands Dark is a custom theme and UI enhancement project for Visual Studio Code that reimagines the editor’s look and feel with a dark, modern aesthetic inspired by JetBrains’ Islands Dark theme, bringing refined visual flair to the development experience. Rather than just changing colors, it introduces visual enhancements such as floating glass-like panels with subtle shadows, rounded corners on UI elements, and smoothly animated transitions that make the editor feel more polished and immersive. The theme pairs deeply dark canvas backgrounds with warm, balanced syntax highlighting for many popular languages, and integrates well with recommended fonts like IBM Plex Mono and FiraCode Nerd Font Mono to improve readability and overall UI harmony. Because it leverages extensions like Custom UI Style and requires some font setup, VSCode Dark Islands aims at users who want a tailored, distinctive editor environment rather than the standard static color scheme. -

ML.NET Samples
Samples for ML.NET, an open source and cross-platform machine learning
ML.NET is a cross-platform open-source machine learning framework that makes machine learning accessible to .NET developers. In this GitHub repo, we provide samples that will help you get started with ML.NET and how to infuse ML into existing and new .NET apps. We're working on simplifying ML.NET usage with additional technologies that automate the creation of the model for you so you don't need to write the code by yourself to train a model, you simply need to provide your datasets. The "best" model and the code for running it will be generated for you. The ML.NET CLI (command-line interface) is a tool you can run on any command prompt (Windows, Mac or Linux) for generating good quality ML.NET models based on training datasets you provide. In addition, it also generates sample C# code to run/score that model plus the C# code that was used to create/train it so you can research what algorithm and settings it is using. -

PowerSharpPack
Offensive CSharp Projects wraped into Powershell for easy usage
PowerSharpPack is a consolidated offensive-security toolkit that wraps many standalone C# projects into an easy-to-use PowerShell loader. The author compiles, gzip-compresses and base64-encodes each C# binary, then dynamically loads the assemblies into the PowerShell process so operators can invoke powerful .NET tools without dropping executables on disk. The bundle exposes a single entry script (PowerSharpPack.ps1) with switches to select which embedded tool to run and an optional -Command argument to pass tool-specific parameters. Included projects cover a broad range of post-exploitation and reconnaissance needs: Kerberos tooling, host survey utilities, credential and browser data extractors, AD enumeration, privilege escalation helpers, persistence frameworks, and file/handle utilities. For convenience the repo also ships per-binary PowerShell loaders when users prefer to avoid loading the entire pack, plus helper binaries used for compression/encoding. -

PowerShellForGitHub
Microsoft PowerShell wrapper for GitHub API
PowerShellForGitHub is a PowerShell module that wraps the GitHub API, allowing administrators and developers to script common GitHub operations directly from the shell. It provides cmdlets for repository management, issue and pull request automation, organization and team administration, and policy tasks such as branch protection or collaborator invites. The module handles authentication flows, pagination, and rate-limit concerns transparently so scripts can focus on business logic like triage, bulk updates, or migration tasks. Because it returns structured objects, outputs are easy to pipe into other PowerShell commands for filtering, reporting, or storage. This makes it a natural fit for CI/CD orchestrations, scheduled housekeeping jobs, or bulk on-boarding workflows where manual web UI clicks would be tedious and error-prone. With commands that mirror everyday GitHub activities, the module helps integrate repository management into standard PowerShell automation estates. -

Scoop Main
The default bucket for Scoop
Scoop’s Main bucket is the primary, default repository (“bucket”) of application manifests for the Scoop package manager on Windows. It holds a curated set of portable or minimally invasive applications that adhere to Scoop’s standards (i.e. apps that don’t heavily depend on installer frameworks or registry tweaks). When a user installs Scoop, the Main bucket is automatically configured, so users can immediately install common command-line tools and utilities without adding extra buckets. The manifests in Main are JSON files that describe how to download, install, uninstall, and manage versions of apps (including dependencies, checksums, etc.). Because it’s the default bucket, maintainers apply stricter validation and review policies to keep Main reliable and safe compared to more experimental or niche buckets. Community contributions are encouraged via pull requests, and the bucket typically evolves with updates, new apps, and deprecations to reflect what users commonly need. -

19
Testimo
Testimo is a PowerShell module for running health checks for AD
Testimo is a PowerShell-based test automation framework that simplifies writing, running, and reporting tests for infrastructure and script libraries. It provides constructs to define test cases, assertions, setup/teardown sequences, and grouping so validation logic is clear and maintainable. Designed for operations and platform engineers, Testimo focuses on verifying infrastructure state (configuration settings, service availability, registry keys) rather than purely unit-level code, making it useful for smoke tests, image validations, and deployment gates. Test runs can emit structured reports, integrate with CI systems, and be scheduled as part of regular compliance checks to ensure environments remain in expected states. Because it’s built on PowerShell, Testimo reuses native cmdlets and objects directly in assertions, reducing the impedance mismatch between tests and target systems. -

Ultimate AppLocker Bypass List
The most common techniques to bypass AppLocker
UltimateAppLockerByPassList is a community-curated repository that collects known techniques, patterns, and candidate binaries that have been observed or proposed to bypass Microsoft AppLocker and similar executable control policies. The project functions as a living catalog: entries list binaries, script hosts, and patterns that researchers have tested or reported in the wild, along with notes about context, platform constraints, and mitigation ideas. It is aimed primarily at defenders, incident responders, and security researchers who need a consolidated reference to understand common bypass vectors and to validate detection logic. The repository emphasizes defensive use—helping blue teams craft allow-list policies, create detection rules, and test policy hardening in isolated lab environments—rather than offensive exploitation. -

Win Debloat Tools
Re-imagining Windows like a minimal OS install
Win Debloat Tools is an open-source PowerShell-based toolkit designed to strip away unnecessary components, preinstalled apps, and services from modern Windows installations to create a leaner, more responsive operating system. It aims to re-imagine Windows as if it were installed in a minimal state, removing bloatware and optional features with minimal impact on core functionality, though it warns users to proceed with caution since changes can be extensive. The project supports both graphical and CLI execution flows that let users individually select tweaks or apply a broad “Apply Tweaks” preset that automates many optimizations at once. It typically creates a system restore point before making changes, and also logs actions for transparency so you can review what was done. Beyond simple removal of apps, it can optimize services, cleanup temporary system files, remove residual Windows.old folders, and generally reduce resource overhead for better performance and battery life. -

Windows Update Disabler - SCRIPT
Enable/Disable Windows Update - 100% WORKING
Have you tried all tutorials how to disable windows update and eventually woke up in the morning finding out your overnight project is gone because windows restarted - again???! No binary files, no hustle, no bullshit. Just batch files. Just unzip anywhere and run setup.bat to install. It will install three tasks into windows scheduler and two shortcuts to start menu (enable_windows_update/disable_windows_update). First task run the script with elevated rights at the boot time. The two remaining tasks are for ENABLE/DISABLE windows update and are triggered "manually" (with shortcuts). If you want to install updates or use Windows store, just run enable_windows_update shortcut from start menu. Again, after installing from Windows store, you can disable WU with disable_windows_update shortcut. After reboot, it will automatically disable updates anyway. For more info - look at the wiki page.
