What is Krawl?

Krawl is a simple cloud native deception server that creates fake web applications with low hanging fruit and juicy fake random information.

It features:

• Spider Trap Pages: Infinite random links to waste crawler resources based on the spidertrap project
• Fake Login Pages: WordPress, phpMyAdmin, admin panels
• Honeypot Paths: Advertised in robots.txt to catch scanners
• Fake Credentials: Realistic-looking usernames, passwords, API keys
• Canary Token Integration: External alert triggering
• Real-time Dashboard: Monitor suspicious activity
• Customizable Wordlists: Easy JSON-based configuration
• Random Error Injection: Mimic real server behavior

🚀 Quick Start

Helm Chart

Install with default values

helm install krawl ./helm \
  --namespace krawl-system \
  --create-namespace

Install with custom values

helm install krawl ./helm \
  --namespace krawl-system \
  --create-namespace \
  --values values.yaml

Install with custom canary token

helm install krawl ./helm \
  --namespace krawl-system \
  --create-namespace \
  --set config.canaryTokenUrl="http://your-canary-token-url"

Uninstall with

helm uninstall krawl --namespace krawl-system

Kubernetes / Kustomize

Apply all manifests

kubectl apply -k manifests/

Retrieve dashboard path

kubectl get secret krawl-server -n krawl-system -o jsonpath='{.data.dashboard-path}' | base64 -d

Uninstall with

kubectl delete -k manifests/

Docker

docker run -d \
  -p 5000:5000 \
  -e CANARY_TOKEN_URL="http://your-canary-token-url" \
  --name krawl \
  ghcr.io/blessedrebus/krawl:latest

Docker Compose

docker-compose up -d

Python 3.11+

Clone the repository

git clone https://github.com/blessedrebus/krawl.git
cd krawl/src

Run the server

python3 server.py

Visit

http://localhost:5000

To access the dashboard

http://localhost:5000/dashboard-secret-path

Configuration via Environment Variables

To customize the deception server installation several environment variables can be specified.

Variable	Description	Default
PORT	Server listening port	5000
DELAY	Response delay in milliseconds	100
LINKS_MIN_LENGTH	Minimum random link length	5
LINKS_MAX_LENGTH	Maximum random link length	15
LINKS_MIN_PER_PAGE	Minimum links per page	10
LINKS_MAX_PER_PAGE	Maximum links per page	15
MAX_COUNTER	Initial counter value	10
CANARY_TOKEN_TRIES	Requests before showing canary token	10
CANARY_TOKEN_URL	External canary token URL	None
DASHBOARD_SECRET_PATH	Custom dashboard path	Auto-generated
PROBABILITY_ERROR_CODES	Error response probability (0-100%)	0

robots.txt

The actual (juicy) robots.txt configuration is the following

Disallow: /admin/
Disallow: /api/
Disallow: /backup/
Disallow: /config/
Disallow: /database/
Disallow: /private/
Disallow: /uploads/
Disallow: /wp-admin/
Disallow: /phpMyAdmin/
Disallow: /admin/login.php
Disallow: /api/v1/users
Disallow: /api/v2/secrets
Disallow: /.env
Disallow: /credentials.txt
Disallow: /passwords.txt
Disallow: /.git/
Disallow: /backup.sql
Disallow: /db_backup.sql

Wordlists Customization

Edit wordlists.json to customize fake data:

{
  "usernames": {
    "prefixes": ["admin", "root", "user"],
    "suffixes": ["_prod", "_dev", "123"]
  },
  "passwords": {
    "prefixes": ["P@ssw0rd", "Admin"],
    "simple": ["test", "password"]
  },
  "directory_listing": {
    "files": ["credentials.txt", "backup.sql"],
    "directories": ["admin/", "backup/"]
  }
}

or values.yaml in the case of helm chart installation

Dashboard

Access the dashboard at http://<server-ip>:<port>/<dashboard-path>

The attackers' triggered honeypot path and the suspicious activity (such as failed login attempts) are logged

The top IP Addresses is shown along with top paths and User Agents

The dashboard shows:

• Total and unique accesses
• Suspicious activity detection
• Honeypot triggers
• Top IPs, paths, and user-agents
• Real-time monitoring

Retrieving Dashboard Path

Check server startup logs

Python/Docker:

docker logs krawl | grep "Dashboard available"

Kubernetes:

kubectl get secret krawl-server -n krawl-system \
  -o jsonpath='{.data.dashboard-path}' | base64 -d && echo

Helm:

kubectl get secret krawl -n krawl-system \
  -o jsonpath='{.data.dashboard-path}' | base64 -d && echo

Deception Techniques

1. Robots.txt Honeypots

Advertises forbidden paths that legitimate crawlers avoid but scanners investigate:

• /admin/, /backup/, /config/
• /credentials.txt, /.env, /passwords.txt

2. Fake Services

Mimics real applications:

• WordPress (/wp-admin, /wp-login.php)
• phpMyAdmin (/phpmyadmin)
• Admin panels (/admin, /login)

3. Credential Traps

Generates realistic but fake:

• Usernames and passwords
• API keys and tokens
• Database connection strings
• AWS credentials

4. Spider Traps

Infinite random links to waste automated scanner time

5. Error Simulation

Random HTTP errors to appear more realistic

Custom Canary Token

Generate a canary token at canarytokens.org and configure:

export CANARY_TOKEN_URL="http://canarytokens.com/..."
python3 src/server.py
