STClient

STClient is a highly obfuscated, performance-optimized Android native client written in C++ with JNI bindings. Designed for runtime enhancement of Unity-based games, it incorporates secure encrypted communication, ESP overlays, inventory manipulation, aimbotting, and advanced UI-interaction through a floating window interface.

This project is intended strictly for educational and research use only.

Key Capabilities

• ESP Overlay Rendering: Real-time drawing of hitboxes, health bars, nicknames, lines, and UI elements based on live positional data.
• Aimbot & Visuals: Auto-aim via circular crosshair, supported by configurable radius settings.
• Encrypted Command Protocol: XOR and AES-based encryption on UDP for integrity-verified messaging.
• Dynamic Feature Switching: In-app toggles and sliders via JNI interface to a Kotlin-based UI.
• Item Management: Skin and inventory changers with JSON-based dynamic injection.
• Cheat Modules: Fast knife, fire rate, no recoil, bunnyhop, wallshot, grenade nukes, and more.
• Self-Integrity & Anti-Tamper: Obfuscation, control flow annotations, recursion traps, and emulator checks.

Dependencies

• Android NDK (C++17)
• RapidJSON
• KittyMemory
• Custom AES and Base64 modules
• Unity-based game process
• JNI and libil2cpp presence

Build Instructions

# Ensure Android NDK environment is configured
Build with Android Studio (r24 NDK recommended)

Runtime Behavior

• UDP port 19132 is used for client-side command dispatch.
• UDP port 19133 is used for incoming ESP state rendering data.
• Secure handshake performed at initialization using AES key exchange and server timestamp validation.
• Obfuscated strings, logic branches, and conditional paths restrict reverse engineering attempts.

Security & Obfuscation

• Extensive use of OBFUSCATE() macros, fake branching (Bloat<N>), and recursive traps.
• JNI URL requests made with fake headers and string decoys.
• Library tamper-detection (frida, vmos, appcloner) and system property validation.
• All event data XOR-encrypted and hex-encoded over network.

Example Feature Set (UI)

• Skin Changer
• Weapon Modifier
• Aimbot
• Inventory Enhancer
• ESP Box/Line/Filled/Health/Nick
• Fast Knife, Bunnyhop, No Recoil
• Unlimited Grenades, Fast Bomb
• Chams & Visual Effects
