Mostlylucid.BotDetection.ApiHolodeck 1.0.0

Mostlylucid.BotDetection.ApiHolodeck

👁 NuGet

A honeypot extension for that creates a fake API "holodeck" for detected bots.

What It Does

Instead of simply blocking detected bots, ApiHolodeck redirects them to fake API endpoints that return realistic-looking but useless data. This:

• Wastes bot resources - They scrape fake data instead of your real content
• Studies bot behavior - You learn what they're looking for
• Contributes to threat intelligence - Reports malicious IPs to Project Honeypot

Quick Start

# Install the package
dotnet add package Mostlylucid.BotDetection.ApiHolodeck

// Program.cs
builder.Services.AddBotDetection();
builder.Services.AddApiHolodeck(options =>
{
 options.MockApiBaseUrl = "http://localhost:5116/api/mock";
 options.Mode = HolodeckMode.RealisticButUseless;
});

app.UseBotDetection();

Requirements

• Mostlylucid.BotDetection - Core bot detection (installed automatically)
• MockLLMApi server - For generating fake responses (requires Ollama)

Setting Up MockLLMApi

1. Install Ollama: https://ollama.ai/
2. Pull a model: ollama pull gemma3:4b
3. Run MockLLMApi (Docker or NuGet package)

# Docker
docker run -p 5116:5116 -e OLLAMA_URL=http://host.docker.internal:11434 scottgal/mockllmapi

# Or add to your app
dotnet add package mostlylucid.mockllmapi

// Add MockLLMApi to your app
builder.Services.AddLLMockApi(config =>
{
 config.OllamaUrl = "http://localhost:11434";
 config.DefaultModel = "gemma3:4b";
});
app.MapLLMockApi("/api/mock");

Components

1. HolodeckActionPolicy

Redirects detected bots to MockLLMApi instead of your real backend.

{
 "BotDetection": {
 "ActionPolicies": {
 "holodeck": {
 "Type": "Holodeck",
 "MockApiBaseUrl": "http://localhost:5116/api/mock",
 "Mode": "realistic-but-useless",
 "MaxStudyRequests": 50
 }
 },
 "DetectionPolicies": {
 "default": {
 "Transitions": [
 { "WhenRiskExceeds": 0.6, "ActionPolicyName": "holodeck" },
 { "WhenRiskExceeds": 0.9, "ActionPolicyName": "block" }
 ]
 }
 }
 }
}

2. HoneypotLinkContributor

Detects when bots access trap paths that real users would never visit.

Built-in honeypot paths include:

• /wp-login.php, /wp-admin - WordPress probes
• /.env, /config.php - Config file access
• /.git/config - Version control exposure
• /phpmyadmin, /adminer.php - Database admin
• /backup.sql, /dump.sql - Database dumps

Any access to these paths = instant high-confidence bot detection.

3. HoneypotReporter

Reports malicious IPs to threat intelligence services (Project Honeypot, AbuseIPDB).

{
 "BotDetection": {
 "Holodeck": {
 "ReportToProjectHoneypot": true,
 "ProjectHoneypotAccessKey": "your-key",
 "MinRiskToReport": 0.85
 }
 }
}

Holodeck Modes

Configuration

{
 "BotDetection": {
 "Holodeck": {
 "MockApiBaseUrl": "http://localhost:5116/api/mock",
 "Mode": "RealisticButUseless",
 "ContextSource": "Fingerprint",
 "MaxStudyRequests": 50,
 "MockApiTimeoutMs": 5000,

 "EnableHoneypotLinkDetection": true,
 "HoneypotPaths": [
 "/admin-secret",
 "/wp-login.php",
 "/.env"
 ],

 "ReportToProjectHoneypot": false,
 "ProjectHoneypotAccessKey": "",
 "MinRiskToReport": 0.85,
 "MaxReportsPerHour": 100
 }
 }
}

How It Works

Request -> BotDetection
 |
 +-- Low Risk -> Real Backend
 |
 +-- High Risk -> HolodeckActionPolicy
 |
 +-- Build context key (fingerprint/IP)
 |
 +-- Forward to MockLLMApi
 | +-- /api/mock/{original-path}?context={key}
 |
 +-- Return LLM-generated fake response
 +-- Bot thinks it's real data!

Each bot gets a consistent fake world based on their fingerprint. If they make 10 requests, they get coherent (but fake) responses. This makes it harder to detect they're being sandboxed.

Context Keys

The ContextSource setting determines how bots are identified:

Study Cutoff

After MaxStudyRequests, the bot is hard-blocked. This prevents infinite resource consumption while still gathering useful intelligence about their scraping patterns.

Example: API Protection

// Protect your API with a holodeck fallback
builder.Services.AddBotDetection(options =>
{
 options.BotThreshold = 0.6; // Lower threshold for holodeck
 options.BlockDetectedBots = false; // Don't block, redirect to holodeck
});

builder.Services.AddApiHolodeck(options =>
{
 options.Mode = HolodeckMode.Adversarial;
 options.MaxStudyRequests = 100;
});

Legitimate users get your real API. Bots get a fake one that wastes their time.
