Anti-AI

🛡️ Anti-AI is a Windows console app built for teamwork as the final exam project for Object-Oriented Programming at ITSTEP (IT SCHOOL). The tool blocks access to popular AI services by combining Windows Filtering Platform (WFP) rules with hosts file overrides.

🧭 Overview

• Resolves a curated list of AI-related domains.
• Blocks outbound connections to the resolved IPs via WFP filters.
• Adds hosts file entries to prevent DNS-based bypass.
• Cleans up on exit or when run with --uninstall.

🧱 Project Architecture

• Main.cpp — app entry point, DNS resolution, WFP filter setup, lifecycle management.
• Config.(h/cpp) — provider/sublayer GUIDs, domain blocklist, hosts path.
• WfpManager.(h/cpp) — WFP provider/sublayer registration and IP filter creation.
• HostsManager.(h/cpp) — patching and cleanup of the Windows hosts file.

Flow: Resolve domains → add WFP block filters → patch hosts file → keep session alive until exit.

✨ Features

• 🔒 Blocks major AI providers (OpenAI, Anthropic, Google, xAI, etc.).
• 🧠 DNS resolution with unique IP de-duplication.
• 🧰 WFP dynamic session (auto-removes filters on close).
• 🧹 Hosts file cleanup and DNS cache flush.
• 🛠️ --uninstall mode to restore access quickly.

🧰 Technologies Used

• C++20
• Windows API (WFP, WinSock, DNS)
• Visual Studio / MSVC (toolset configured in the project)

▶️ How to run this project?

⚠️ Administrator privileges required (WFP + hosts file edits).

1. Open Anti-AI.slnx in Visual Studio 2022.
2. Build Release | x64.
3. Run the generated .exe as Administrator.
4. Keep the window open to keep blocking active.
5. To uninstall/cleanup:

   Anti-AI.exe --uninstall
