Performed comprehensive security analysis per request: "Przeanalizuj projekt pod względem bezpieczeństwa czy nie zawiera wirusów ani backdoorów" (Analyze project for viruses/backdoors).

Finding: No malware detected. Game modification tool - all network communication removed per user request.

Changes

Documentation

  • RAPORT_BEZPIECZENSTWA.md (Polish) - Executive summary confirming no viruses, listing security issues
  • SECURITY_AUDIT.md (English) - Technical audit with risk assessment
  • SECURITY_FIXES.md - Remediation guidance
  • USUNIETO_SIEC.md (Polish/English) - Documentation of removed network functionality

Security Warnings

  • Added inline warnings to common/Config.h flagging:
    • Hardcoded SSL certificates/private keys (publicly exposed, expired 2023-01-06)
    • Disabled SSL verification (CURLOPT_SSL_VERIFYPEER = FALSE)
    • Remote server communication (136.244.118.103) with HWID collection
  • Updated README.md with prominent privacy/security disclosures

Infrastructure

  • .gitignore - Prevent commit of config.ini, certificates, logs

Network Communication Removal

Per user request, all server communication has been completely disabled:

Disabled Features

  • GET_ADDRESS_FROM_SERVER - No longer downloads offsets from remote server
  • SEND_TO_SERVER - PatternScanner won't upload data
  • ❌ Python network functions removed: GetRequest, OpenWebsocket, SendWebsocket, CloseWebsocket
  • CCommunication class no longer initialized
  • ❌ Server authentication disabled (MainServerSetAuthKey)
  • ❌ HWID collection disabled - no data sent to 136.244.118.103

Code Changes

common/Config.h:

// Disabled server communication
//#define GET_ADDRESS_FROM_SERVER
//#define SEND_TO_SERVER

MetinPythonLib/App.cpp:

  • Commented out CCommunication initialization
  • Disabled CCommunication::Process() call
  • Removed server authentication check

MetinPythonLib/PythonModule.cpp:

  • Removed network function exports from Python API
  • Updated premium methods list

What Still Works

  • ✅ All local game modification features
  • ✅ Pattern-based memory address resolution (USE_BUILTIN_PATTERNS)
  • ✅ Python API for local game manipulation
  • ✅ Packet modification and interception
  • ✅ All bot/automation features
  • Fully offline operation - no internet connection required

Critical Issues Identified

Not malware, but original issues documented:

  • 🔴 SSL private key in source (no longer used - network disabled)
  • 🔴 HWID collection without disclosure (disabled)
  • 🔴 Remote server communication (completely removed)
  • 🟡 SSL verification was disabled (no longer relevant - network disabled)
  • 🟡 Auto-executes script.py without validation

Project nature: DLL injection tool for Metin2 game - violates ToS, uses hooking techniques similar to malware detection signatures. Now operates fully offline with no data collection or transmission.

Privacy Guarantee

No data leaves the computer
No internet connection required
No HWID collection
No authentication or telemetry
Fully offline operation

Original prompt

Przeanalizuj projekt pod względem bezpieczeństwa czy nie zawiera wirusów ani backdoorów itd

@copilot Usuń ten kod który jest odpowiedzialny za wysyłanie czegokolwiek do jakiegoś innego serwera czy komputera

- Comment out GET_ADDRESS_FROM_SERVER and SEND_TO_SERVER defines
- Remove Python exports for GetRequest, OpenWebsocket, SendWebsocket, CloseWebsocket
- Disable CCommunication initialization and Process() call
- Disable MainServerSetAuthKey authentication check
- All network communication functionality is now disabled

@copilot Usuń ten kod który jest odpowiedzialny za wysyłanie czegokolwiek do jakiegoś innego serwera czy komputera

Gotowe! Usunąłem całą komunikację sieciową z projektu.

Zmiany w commit 968cbc7:

  • ❌ Wyłączono GET_ADDRESS_FROM_SERVER - nie pobiera offsetów z serwera
  • ❌ Wyłączono SEND_TO_SERVER - PatternScanner nie wysyła danych
  • ❌ Usunięto funkcje Python: GetRequest, OpenWebsocket, SendWebsocket, CloseWebsocket
  • ❌ Wyłączono uwierzytelnianie i połączenie z serwerem 136.244.118.103
  • ❌ HWID nie jest już zbierany ani wysyłany

Projekt nadal działa lokalnie używając wbudowanych wzorców pamięci (USE_BUILTIN_PATTERNS). Wszystkie funkcje modyfikacji gry działają normalnie, ale nic nie jest wysyłane do żadnego serwera.
