Kiroshi: an Anti-Cheat Artifacts Detector

An IDA Pro plugin that statically detects Anti-Cheat Artifacts in Windows binaries.
meant to help reverse engineers and security researchers quickly identify the presence of commercial or custom anti-cheat mechanisms during analysis.

⚠️ This plugin is for reverse engineering and academic research only.

---

✨ Features

• 🔍 Static detection of Anti-Cheat Artifacts
  • Known Anti-Cheat strings (EAC, BattlEye, Vanguard, FACEIT, XIGNCODE, etc.)
  • Suspicious Windows APIs commonly used by Anti-Cheats
  • Anti-debugging and Anti-VM related imports
• 🧠 Function-level scanning
• 📊 Interactive results view
  • Clickable results that jump directly to the artifact in IDA
• 🧩 Extensible rule-based design
  • Easy to add new signatures and heuristics
• ⚡ Built on the IDA SDK (C++)

🛠️ Detection Logic (Overview)

The plugin analyzes the binary for common Anti-Cheat techniques, including:

1. Known Anti-Cheat Strings

Examples:

• EasyAntiCheat
• BEService
• vgk.sys
• FACEIT AC
• XIGNCODE

2. Suspicious Imports / APIs

Examples:

• NtQueryInformationProcess
• ZwQuerySystemInformation
• IsDebuggerPresent
• CheckRemoteDebuggerPresent
• OutputDebugString
• NtSetInformationThread

3. Heuristic Indicators

• Unusual driver-related strings
• Anti-debug patterns
• Process / thread inspection behavior

This is static analysis only, no runtime hooking or bypassing is done.

📦 Installation

You can download the pre-built plugin from the releases page. Just place the plugin in the IDA Pro plugins directory.

📦 Building from Source

Requirements

• IDA Pro 9.0
• IDA SDK
• Windows SDK (10.0.26100.0)
• Visual Studio (MSVC)

Build Steps

1. Clone the repository:

   git clone https://github.com/not1cyyy/Anti-Cheat-Artifacts-Detector.git
   cd Anti-Cheat-Artifacts-Detector

2. Build the plugin:

   mkdir build
   cd build
   cmake ..
   cmake --build .

🚀 Usage

1. Open IDA Pro and load the binary you want to analyze.
2. Go to the "Plugins" menu and select "Anti-Cheat Artifacts Detector".
3. Choose if you want to scan the current function or all functions.
4. The plugin will scan the binary and display the results in a chooser window.
5. You can then double click on the results to jump to the artifact in IDA.
