Evidence-based anti-cheat for Counter-Strike 1.6.
A Windows scanner, a web report dashboard and a ReHLDS server engine —
built to collect strong evidence, explain it clearly, and leave every ban to a human.

🧭 What is ACS?
| |
|---|
| 🖥️ Desktop scanner | A Windows app that attaches to a running hl.exe, inventories the game, and checks it against a signature database and an artifact corpus before uploading a signed report. |
| 🌐 Report dashboard | The operator-side web service that stores reports, shows what was found, and separates confirmed detections from lower-confidence review items. |
| 🛡️ Server engine | An optional ReHLDS plugin that analyses how a player actually plays — aim, recoil, movement, timing — with no client cooperation. |
📸 The App
Every scan ends in a written disclosure: the signed report uploads automatically to your configured operator.
🔍 What the scanner checks
| |
|---|
| 🧩 Module integrity | Engine code compared byte-for-byte against the file on disk — inline hooks, detours, mid-function patches, IAT and EAT hooks. |
| 🧠 Memory evidence | Private executable regions that back no file on disk — the manual-map signature. |
| 👁️ External-cheat probes | Processes holding read/write handles on the game, foreign threads, overlay windows. |
| 📜 Database policy | Current server rules at each scan; exact filenames from the detection database, administrator overrides and verified content hashes. |
| 🗂️ Processes & drivers | Running executable hashes and OS-reported driver inventory with signature state. |
| 🎮 Client recognition | Steam, NextClient, GSClient, GoldClient, RevEmu/RevCrew, SmartSteamEmu, Goldberg — identified, not flagged. |
| 🗃️ Artifact corpus | Historical hash context for review; prevalence alone does not certify a file as clean. |
