LongHorn ACS

     

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.

[!IMPORTANT] Public distribution and transparency repository. Scanner source, detection databases, server code, credentials and player reports are not published here. This repository is not an open-source release of the scanner.

🧭 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.

Detected	Review

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.
