When an attacker interacts with a canary token, it immediately triggers an alert\nwith near-zero false positives. Unlike signature-based detection, canary tokens detect\nattackers by their behavior (accessing bait resources) rather than matching known patterns.\n\n### Token Types for Network Intrusion Detection\n\n| Token Type | Trigger Mechanism | Best Placement | Detection Scenario |\n|------------|-------------------|----------------|-------------------|\n| DNS Token | DNS resolution of FQDN | Config files, scripts, internal docs | Attacker reads configs during recon |\n| HTTP Token | HTTP GET to unique URL | Internal wikis, bookmark files, HTML | Attacker browses internal resources |\n| AWS API Key | AWS API call with fake creds | `.aws/credentials`, env files, repos | Attacker tests found credentials |\n| Cloned Site | Visit to cloned page | Internal portals, admin panels | Attacker accesses cloned services |\n| SVN Token | SVN checkout | Repository configs | Attacker clones repositories |\n| SQL Server | Database login attempt | Connection strings, config files | Attacker attempts DB access |\n\n### Alert Flow Architecture\n\n```\n[Attacker Action] --> [Token Triggered] --> [Canarytokens Server]\n                                                    |\n                                            [Webhook POST]\n                                                    |\n                          +-------------------------+-------------------------+\n                          |                         |                         |\n                    [Slack Alert]           [Email Alert]             [SIEM Ingestion]\n                          |                         |                         |\n                    [SOC Analyst]           [On-Call Page]           [Correlation Rule]\n```\n\n## Instructions\n\n### Step 1: Generate DNS Canary Tokens\n\nDNS tokens are the most versatile -- they trigger on any DNS resolution, even from\nair-gapped networks with only DNS egress. The token is an FQDN that, when resolved,\nalerts the token owner.\n\n```python\nimport requests\n\n# Create DNS canary token via Canarytokens.org\nresponse = requests.post(\"https://canarytokens.org/generate\", data={\n    \"type\": \"dns\",\n    \"email\": \"soc@company.com\",\n    \"memo\": \"Production database server - /etc/app/db.conf\",\n    \"webhook_url\": \"https://hooks.slack.com/services/T.../B.../xxx\"\n}, timeout=15)\n\ntoken_data = response.json()\ndns_hostname = token_data[\"hostname\"]\n# Example: abc123def456.canarytokens.com\n```\n\nPlant DNS tokens in locations attackers commonly inspect:\n- `/etc/hosts` entries pointing to the canary FQDN\n- Application configuration files (`database_host`, `backup_server`)\n- SSH config files (`~/.ssh/config`) with canary hostnames\n- Internal DNS zone files as decoy A records\n- CI/CD pipeline environment variables\n\n### Step 2: Deploy HTTP Canary Tokens\n\nHTTP tokens generate a unique URL that triggers on any HTTP request. They reveal the\nsource IP, User-Agent, and other HTTP headers of the requester.\n\n```python\n# Create HTTP token\nresponse = requests.post(\"https://canarytokens.org/generate\", data={\n    \"type\": \"http\",\n    \"email\": \"soc@company.com\",\n    \"memo\": \"Internal wiki - IT admin passwords page\",\n    \"webhook_url\": \"https://hooks.slack.com/services/T.../B.../xxx\"\n}, timeout=15)\n\nhttp_url = response.json()[\"url\"]\n# Embed in internal HTML pages, documents, or bookmark files\n```\n\nPlacement strategies for HTTP tokens:\n- Hidden `<img>` tags in internal wiki pages with sensitive titles\n- URL shortener redirects in shared bookmark collections\n- Links in internal documentation labeled \"admin credentials\" or \"VPN configs\"\n- `.url` or `.webloc` shortcut files in network shares\n- Browser bookmark exports in user profile backups\n\n### Step 3: Create AWS API Key Tokens\n\nAWS key tokens are among the highest-fidelity canary tokens. They generate real-looking\nAWS access keys that trigger an alert whenever anyone attempts to use them against any\nAWS API endpoint.\n\n```python\n# Create AWS API key canary token\nresponse = requests.post(\"https://canarytokens.org/generate\", data={\n    \"type\": \"aws_keys\",\n    \"email\": \"soc@company.com\",\n    \"memo\": \"DevOps jump box - /home/deploy/.aws/credentials\",\n    \"webhook_url\": \"https://hooks.slack.com/services/T.../B.../xxx\"\n}, timeout=15)\n\naws_token = response.json()\naccess_key_id = aws_token[\"access_key_id\"]\nsecret_access_key = aws_token[\"secret_access_key\"]\n```\n\nDeploy the fake credentials:\n```ini\n# Place in ~/.aws/credentials on honeypot or jump servers\n[default]\naws_access_key_id = AKIAIOSFODNN7EXAMPLE\naws_secret_access_key = wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY\nregion = us-east-1\n\n# Also plant in:\n# - .env files in code repositories\n# - Docker environment configurations\n# - Terraform state files (decoy)\n# - Jenkins/CI credential stores\n```\n\n### Step 4: Configure Webhook Alert Integration\n\nSet up real-time alerting to your SOC through multiple channels:\n\n```python\n# Slack webhook integration\ndef send_slack_alert(webhook_url, alert_data):\n    \"\"\"Forward canary token alert to Slack channel.\"\"\"\n    payload = {\n        \"text\": f\":rotating_light: *Canary Token Triggered*\",\n        \"attachments\": [{\n            \"color\": \"#FF0000\",\n            \"fields\": [\n                {\"title\": \"Token Memo\", \"value\": alert_data.get(\"memo\", \"Unknown\"), \"short\": True},\n                {\"title\": \"Source IP\", \"value\": alert_data.get(\"src_ip\", \"Unknown\"), \"short\": True},\n                {\"title\": \"Token Type\", \"value\": alert_data.get(\"channel\", \"Unknown\"), \"short\": True},\n                {\"title\": \"Triggered At\", \"value\": alert_data.get(\"time\", \"Unknown\"), \"short\": True},\n            ],\n            \"footer\": \"Canarytokens Alert System\",\n        }]\n    }\n    requests.post(webhook_url, json=payload, timeout=10)\n```\n\n```python\n# Generic webhook receiver (Flask) for SIEM ingestion\nfrom flask import Flask, request, jsonify\nimport json, logging\n\napp = Flask(__name__)\nlogging.basicConfig(filename=\"/var/log/canary_alerts.json\", level=logging.INFO)\n\n@app.route(\"/canary-webhook\", methods=[\"POST\"])\ndef receive_alert():\n    alert = request.json or request.form.to_dict()\n    logging.info(json.dumps({\n        \"event_type\": \"canarytoken_triggered\",\n        \"memo\": alert.get(\"memo\"),\n        \"src_ip\": alert.get(\"src_ip\"),\n        \"token_type\": alert.get(\"channel\"),\n        \"time\": alert.get(\"time\"),\n        \"manage_url\": alert.get(\"manage_url\"),\n        \"additional_data\": alert.get(\"additional_data\", {}),\n    }))\n    return jsonify({\"status\": \"received\"}), 200\n```\n\n### Step 5: Enterprise Deployment with Thinkst Canary API\n\nFor organizations using Thinkst Canary, leverage the API for mass deployment and\ncentralized management:\n\n```python\nimport canarytools\n\n# Connect to Thinkst Canary console\nconsole = canarytools.Console(\n    domain=\"yourcompany\",\n    api_key=YOUR_KEY\n)\n\n# Create tokens programmatically at scale\ntoken_types = {\n    \"dns\": \"DNS beacon in config files\",\n    \"aws-id\": \"AWS credentials on jump servers\",\n    \"http\": \"Web bug in internal documentation\",\n    \"doc-msword\": \"Word document in finance share\",\n    \"slack-api\": \"Fake Slack bot token in source code\",\n}\n\nfor kind, memo in token_types.items():\n    result = console.tokens.create(memo=memo, kind=kind)\n    print(f\"[+] Created {kind} token: {result}\")\n\n# Monitor for triggered alerts\nalerts = console.tokens.alerts()\nfor alert in alerts:\n    print(f\"[ALERT] {alert.memo} triggered from {alert.src_ip}\")\n```\n\n### Step 6: Token Placement Strategy by Network Zone\n\n**DMZ / Public-Facing:**\n- HTTP tokens in admin panel login pages (hidden image tag)\n- DNS tokens in web server configuration files\n- AWS keys in `.env` files on staging servers\n\n**Internal Network / Corporate:**\n- DNS tokens in Active Directory Group Policy scripts\n- AWS keys in developer workstation backup directories\n- HTTP tokens in internal SharePoint/Confluence pages titled \"Emergency Credentials\"\n- Word document tokens in network shares (`\\\\fileserver\\IT\\passwords.docx`)\n\n**Production / Data Center:**\n- DNS tokens in database configuration files\n- AWS keys in CI/CD environment variables\n- SQL Server tokens in connection strings on application servers\n- SVN/Git tokens in repository configuration files\n\n**Cloud Infrastructure:**\n- AWS key tokens in S3 bucket policies (decoy)\n- DNS tokens in CloudFormation/Terraform templates\n- HTTP tokens in Lambda function environment variables\n- Cloned-site tokens mimicking cloud admin consoles\n\n## Examples\n\n### Full Deployment Script\n\n```python\n# Deploy a comprehensive canary token network\npython scripts/agent.py --action full_deploy \\\n    --email soc@company.com \\\n    --webhook https://hooks.slack.com/services/T.../B.../xxx \\\n    --output deployment_report.json\n```\n\n### Monitor Triggered Tokens\n\n```python\n# Check for triggered alerts\npython scripts/agent.py --action monitor \\\n    --console-domain yourcompany \\\n    --api-key YOUR_AUTH_TOKEN\n```\n\n### Generate Token Inventory\n\n```python\n# Create inventory of all deployed tokens\npython scripts/agent.py --action inventory \\\n    --output token_inventory.json\n```\n\n## Validation Checklist\n\n- [ ] DNS tokens resolve correctly and generate alerts within 60 seconds\n- [ ] HTTP tokens return a valid response and log source IP\n- [ ] AWS key tokens trigger alerts when used with `aws sts get-caller-identity`\n- [ ] Webhook alerts arrive in Slack/Teams/SIEM within acceptable latency\n- [ ] Token memo fields contain sufficient context for SOC triage\n- [ ] Deployment locations are documented in token inventory\n- [ ] Alert escalation procedures are defined and tested\n- [ ] Tokens do not interfere with legitimate operations\n- [ ] Self-hosted Canarytokens instance (if used) is hardened and monitored\n- [ ] Token rotation schedule is established (quarterly recommended)\n\n## References\n\n- Canarytokens Documentation: https://docs.canarytokens.org/guide/\n- Thinkst Canary Platform: https://canary.tools/\n- Thinkst Canary API:
