implementing-honeytokens-for-breach-detection	Deploys canary tokens and honeytokens (fake AWS credentials, DNS canaries, document beacons, database records) that trigger alerts when accessed by attackers. Uses the Canarytokens API and custom webhook integrations for breach detection. Use when building deception-based early warning systems for intrusion detection.	cybersecurity	security-operations	implementing honeytokens for breach	1.0	mahipal	MIT

Implementing Honeytokens for Breach Detection

Instructions

Deploy honeytokens across critical systems to detect unauthorized access. Each token type alerts via webhook when triggered by an attacker.

import requests

# Create a DNS canary token via Canarytokens
resp = requests.post("https://canarytokens.org/generate", data={
    "type": "dns",
    "email": "soc@company.com",
    "memo": "Production DB server honeytoken",
})
token = resp.json()
print(f"DNS token: {token['hostname']}")

Token types to deploy:

1. AWS credential files (~/.aws/credentials) with canary keys
2. DNS tokens embedded in configuration files
3. Document beacons (Word/PDF) in sensitive file shares
4. Database honeytoken records in user tables
5. Web bugs in internal wiki/documentation pages

Examples

# Generate a fake AWS credentials file with canary token
aws_creds = f"[default]\naws_access_key_id = {canary_key_id}\naws_secret_access_key = {canary_secret}\n"
with open("/opt/backup/.aws/credentials", "w") as f:
    f.write(aws_creds)
