Overview

HVNC PoC (Hidden Virtual Network Computing) is a Rust-based proof-of-concept demonstrating how to create a hidden Windows desktop, launch Google Chrome within it, and capture screenshots of the hidden browser window—all without displaying Chrome to the main user session.

Features

• 🖥️ Hidden Desktop: Creates a hidden Windows desktop using native Win32 APIs
• 🌐 Chrome Automation: Launches Google Chrome in the hidden desktop
• 🪟 Window Enumeration: Detects and enumerates Chrome windows
• 📸 Screenshot Capture: Captures and saves screenshots of Chrome windows

---

How It Works

1. Hidden Desktop Creation: Uses Win32 APIs to create and switch to a hidden desktop.
2. Chrome Launch: Starts a new Chrome process in the hidden desktop.
3. Window Enumeration: Finds Chrome windows and checks their visibility.
4. Screenshot Capture: Captures the window content and saves it as a PNG file.

---

Requirements

• Windows 10/11 (x64)
• Rust toolchain (1.70 or newer recommended)
• Google Chrome (default path: C:\Program Files\Google\Chrome\Application\chrome.exe)
• Rust dependencies (managed by Cargo):
• image
• anyhow
• chrono
• windows

---

Installation

1. Clone the repository: sh git clone <this-repo-url> cd hidden-vnc
2. Edit the Chrome path if needed: Open src/main.rs and update the chrome_path variable if your Chrome is installed elsewhere.
3. Build the project: sh cargo build --release

---

Usage

Run the PoC from the project root:

cargo run --release

• Screenshots will be saved in the screenshots/ directory.
• The program will print status messages to the console, including the location of saved screenshots and any errors encountered.
