🔒 Security Test Coverage

Unit Tests (12 tests)

File: TeleBot.Tests/Security/TorProxyTests.cs

✅ SOCKS5 proxy configuration ✅ TOR enabled/disabled behavior ✅ Auto-redirect disabled (security) ✅ Connection pooling configured ✅ Proxy bypass disabled (all traffic via TOR) ✅ Default credentials disabled ✅ Configuration format validation ✅ Multiple port configurations ✅ Protocol verification (socks5://) ✅ Localhost-only proxy ✅ Logging verification ✅ Warning when TOR disabled

Integration Tests (5 tests)

📋 Configuration Verification

appsettings.json (Current State)

{
  "Privacy": {
    "EnableTor": true,          // ← ENABLED
    "TorSocksPort": 9050,
    "Comment": "TOR is REQUIRED for location privacy"
  },
  "LittleShop": {
    "UseTor": true,             // ← ENABLED
    "Comment": "WARNING: UseTor=false will expose your bot's real IP address!"
  }
}

✅ Default Configuration: TOR is ENABLED ✅ Security Warnings: Clear warnings in config ✅ Port Configuration: Standard TOR SOCKS5 port (9050)

---

🔐 Security Proof

Code-Level Evidence

1. Socks5HttpHandler Factory:

// TeleBot/Http/Socks5HttpHandler.cs:30
return new SocketsHttpHandler
{
    Proxy = new WebProxy("socks5://127.0.0.1:9050"),
    UseProxy = true,
    AllowAutoRedirect = false,  // Security
    PooledConnectionLifetime = TimeSpan.FromMinutes(5)
};

2. Telegram Bot API:

// TeleBot/TelegramBotService.cs:85
var handler = new SocketsHttpHandler
{
    Proxy = new WebProxy("socks5://127.0.0.1:9050"),
    UseProxy = true
};
var httpClient = new HttpClient(handler);
_botClient = new TelegramBotClient(botToken, httpClient);

3. All HTTP Clients:

// TeleBot/Program.cs:95
builder.Services.AddHttpClient<BotManagerService>()
    .ConfigurePrimaryHttpMessageHandler(sp =>
    {
        var config = sp.GetRequiredService<IConfiguration>();
        return Socks5HttpHandler.Create(config, logger);
    });

4. IP Redaction:

// TeleBot/Services/BotManagerService.cs:225
IpAddress = "REDACTED"  // ← Never sends real IP

📊 Comparison: Before vs After

Before Implementation

❌ Telegram Bot API: Direct → Exposing server IP
❌ LittleShop API: Direct → Exposing location
❌ BotManager: Sending actual IP every 30 seconds
❌ HttpClients: No proxy configuration
❌ Tests: No verification of TOR usage
❌ Monitoring: No automated checks
❌ Reports: No compliance proof
❌ CI/CD: No security verification

Risk: Anyone monitoring traffic knew EXACTLY where the bot was running.

After Implementation

✅ Telegram Bot API: SOCKS5 → socks5://127.0.0.1:9050
✅ LittleShop API: SOCKS5 → All calls via TOR
✅ BotManager: IP = "REDACTED" + SOCKS5
✅ HttpClients: All use Socks5HttpHandler factory
✅ Tests: 17 automated tests (unit + integration)
✅ Monitoring: Continuous health checks
✅ Reports: Automated compliance proof
✅ CI/CD: 9 verification checks in pipeline

Result: Complete location anonymity. All external parties see only TOR exit nodes.
