About ThickAC
ThickAC is a lightweight anti-cheat solution designed to protect game servers without interfering with normal gameplay.
It focuses on effective cheat detection while keeping system usage low and avoiding unnecessary client-side complexity.

Unlike many anti-cheat systems, ThickAC does not require client-side code virtualization or deep rewrites, since protection and obfuscation are already implemented within the anti-cheat module itself.
Installation and removal are straightforward.

Real Usage & Testing
Quote:
ThickAC was actively used on a live server a few months ago. During this period, detections were monitored for testing and observation purposes only, and no server-side actions or punishments were applied to players.
This phase provided practical insight into system behavior in a live environment.

Does It Actually Work?
This is the most common and fair question.

ThickAC was developed by someone with extensive hands-on experience working against existing protection systems, including:
- Anti-cheat solutions commonly used on Turkish servers
- Various foreign protection systems
- Large-scale servers such as Aeldra
- Practical knowledge gained from actively breaking, testing, and bypassing these protections to understand their real weaknesses

Because of this background, ThickAC focuses on detection methods that are difficult to bypass and hard to silence.
Its detection logic does not rely on fragile tricks or noisy methods, but on practical techniques used in real cheat environments.

The system is built to:
- Detect advanced cheats, including Python-based tools
- Identify automation and farm bots
- Remain stable under bypass attempts
- Continue logging even when cheats attempt to interfere with detection

The goal is not to claim “perfect protection”, but to provide a system that reliably detects cheats without disrupting legitimate players.

Privacy & Player Respect
ThickAC does NOT:
- Capture in-game screenshots
- Log window contents
- Inspect unrelated applications unnecessarily

Instead, it uses:
- Targeted memory checks for advanced and scripted cheats
- Handle- and behavior-based checks for simpler cheats and automation

Detection is focused on cheats — not on invading player privacy.

Server Owner Control
All decisions remain fully under server owner control:
- Choose whether detections are logged or acted upon
- Decide between manual review or automated responses
- Ban or unban machines at your own discretion

ThickAC enforces rules — it does not create them.

Streamer & Software Compatibility
ThickAC does not block:
- Virtual machines
- OBS
- Screen recording or streaming software

Players are free to stream, record, and use common tools without restrictions caused by the anti-cheat.

Technical Highlights
- Rule-based detection system with flexible configuration
- Very low CPU usage
- Signed module (helps reduce antivirus false positives)
- Simple and fast installation
- Tested on Windows 8 through Windows 11
- Supports both x86 and x64 modules (current tests performed on x86 clients)

Important Notes
- Attack speed and movement speed exploits are NOT handled client-side
These must be prevented on the server side

Final Notes
ThickAC is built to run reliably during real gameplay.
It prioritizes reliable detection and long-term maintainability over aggressive or intrusive measures.
