Performing Deception Technology Deployment

When to Use

Use this skill when:

• SOC teams need high-fidelity detection of post-compromise lateral movement with near-zero false positives
• Existing detection tools miss advanced attackers who avoid triggering threshold-based alerts
• The organization wants to detect credential abuse by planting fake credentials as honeytokens
• Network segmentation gaps need compensating detection controls

Do not use as a replacement for fundamental security controls (patching, EDR, network segmentation) — deception is a detection layer, not a prevention mechanism.

Prerequisites

• Network segments identified for honeypot/decoy deployment (server VLANs, DMZ, OT networks)
• Deception platform (Thinkst Canary, Attivo/SentinelOne Hologram, or open-source alternatives)
• SIEM integration for deception alerts (any interaction with deception assets is suspicious)
• Active Directory access for honeytoken account and credential creation
• Network team coordination for IP allocation and traffic routing

Workflow

Step 1: Map Attack Surface for Deception Placement

Identify high-value network segments where attackers would traverse:

DECEPTION DEPLOYMENT MAP
━━━━━━━━━━━━━━━━━━━━━━━━
Segment              Decoy Type          Rationale
Server VLAN          Fake file server    Attackers enumerate SMB shares during recon
Database VLAN        Fake DB server      SQL scanning detected in past incidents
AD/DC Segment        Honeytoken account  Credential theft detection
Executive Subnet     Fake workstation    Targeted attacks pivot through exec systems
DMZ                  Honeypot web app    External attacker detection
OT Network           Fake PLC/HMI        Industrial threat detection
Cloud (AWS VPC)      Canary EC2 + S3     Cloud lateral movement detection

Step 2: Deploy Thinkst Canary Devices

Configure Canary devices mimicking real infrastructure:

Windows File Server Canary:

{
  "device_name": "FILESERVER-BK04",
  "personality": "windows-server-2019",
  "services": {
    "smb": {
      "enabled": true,
      "shares": ["Finance_Backup", "HR_Archive", "IT_Docs"],
      "files": [
        {"name": "Q4_Revenue_2024.xlsx", "alert_on": "read"},
        {"name": "employee_ssn_export.csv", "alert_on": "read"},
        {"name": "admin_passwords.kdbx", "alert_on": "read"}
      ]
    },
    "rdp": {"enabled": true},
    "http": {"enabled": false}
  },
  "network": {
    "ip": "10.0.5.200",
    "hostname": "FILESERVER-BK04",
    "domain": "company.local"
  },
  "alert_webhook": "https://soar.company.com/api/webhook/canary"
}

Database Server Canary:

{
  "device_name": "DB-ARCHIVE-02",
  "personality": "linux-mysql",
  "services": {
    "mysql": {
      "enabled": true,
      "port": 3306,
      "databases": ["customer_pii", "payment_archive"],
      "alert_on_login_attempt": true
    },
    "ssh": {
      "enabled": true,
      "port": 22,
      "alert_on_login_attempt": true
    }
  },
  "network": {
    "ip": "10.0.10.50",
    "hostname": "db-archive-02"
  }
}

Step 3: Deploy Honeytokens in Active Directory

Create fake privileged accounts that should never be used:

# Create honeytoken service account
New-ADUser -Name "svc_sql_backup" `
    -SamAccountName "svc_sql_backup" `
    -UserPrincipalName "svc_sql_backup@company.local" `
    -Description "SQL Backup Service Account - DO NOT DELETE" `
    -AccountPassword (ConvertTo-SecureString "FakeP@ssw0rd2024!" -AsPlainText -Force) `
    -Enabled $true `
    -PasswordNeverExpires $true `
    -CannotChangePassword $true

# Add to a group that looks attractive (but monitor for any use)
Add-ADGroupMember -Identity "Domain Admins" -Members "svc_sql_backup"

# Place cached credentials on decoy workstation
# (Mimikatz/credential dumping will find these)
cmdkey /add:fileserver-bk04.company.local /user:company\svc_sql_backup /pass:FakeP@ssw0rd2024!

Monitor honeytoken usage in Splunk:

index=wineventlog sourcetype="WinEventLog:Security"
(EventCode=4624 OR EventCode=4625 OR EventCode=4648 OR EventCode=4768 OR EventCode=4769)
TargetUserName="svc_sql_backup"
| eval alert_severity = "CRITICAL"
| eval alert_message = "HONEYTOKEN ACCOUNT USED — Likely credential theft detected"
| table _time, EventCode, src_ip, ComputerName, TargetUserName, Logon_Type, alert_message

Step 4: Deploy Canary Files and Documents

Plant tracked documents that beacon when opened:

Canary Document (Word doc with tracking):

# Using Thinkst Canary API to create a canary token document
import requests

response = requests.post(
    "https://YOURCOMPANY.canary.tools/api/v1/canarytoken/create",
    data={
        "auth_token": "YOUR_API_TOKEN",
        "kind": "doc-msword",
        "memo": "Finance backup folder canary document",
        "flock_id": "flock:default"
    }
)
token = response.json()
download_url = token["canarytoken"]["canarytoken_url"]
print(f"Download canary doc: {download_url}")
# Place this document in honeypot SMB shares and sensitive directories

AWS Canary Token (S3 access key):

# Create AWS canary token — alerts when access key is used
response = requests.post(
    "https://YOURCOMPANY.canary.tools/api/v1/canarytoken/create",
    data={
        "auth_token": "YOUR_API_TOKEN",
        "kind": "aws-id",
        "memo": "Canary AWS key in developer laptop .aws/credentials"
    }
)
aws_keys = response.json()
print(f"Access Key: {aws_keys['canarytoken']['access_key_id']}")
print(f"Secret Key: {aws_keys['canarytoken']['secret_access_key']}")
# Plant in .aws/credentials on developer workstations

Step 5: Integrate Deception Alerts with SIEM/SOAR

All deception alerts are high-fidelity — any interaction is suspicious:

Splunk Alert for Canary Triggers:

index=canary sourcetype="canary:alerts"
| eval severity = "CRITICAL"
| eval confidence = "HIGH — Deception asset triggered, zero false positive expected"
| table _time, canary_name, alert_type, source_ip, service, details
| sendalert create_notable param.rule_title="Deception Alert — Canary Triggered"
  param.severity="critical" param.drilldown_search="index=canary source_ip=$source_ip$"

SOAR Automated Response:

def canary_triggered(container):
    """Auto-response for deception alerts — high confidence, no approval needed"""
    source_ip = container["artifacts"][0]["cef"]["sourceAddress"]

    # Immediately isolate the source
    phantom.act("quarantine device",
                parameters=[{"ip_hostname": source_ip}],
                assets=["crowdstrike_prod"],
                name="isolate_attacker_host")

    # Block at firewall
    phantom.act("block ip",
                parameters=[{"ip": source_ip, "direction": "both"}],
                assets=["palo_alto_prod"],
                name="block_attacker_ip")

    # Create high-priority incident
    phantom.act("create ticket",
                parameters=[{
                    "short_description": f"DECEPTION ALERT: Canary triggered from {source_ip}",
                    "urgency": "1",
                    "impact": "1"
                }],
                assets=["servicenow_prod"])

    phantom.set_severity(container, "critical")

Step 6: Maintain Deception Realism

Regularly update decoys to maintain believability:

• Rotate honeytoken passwords quarterly (update cached credentials on decoy workstations)
• Update canary file modification dates to appear recently accessed
• Add realistic network traffic to honeypots (scheduled SMB enumeration, DNS lookups)
• Register honeypot hostnames in DNS and Active Directory to appear in network scans
• Update canary document contents to match current business context

Key Concepts

Term	Definition
Honeypot	Decoy system mimicking real infrastructure to attract and detect attackers in the network
Honeytoken	Fake credential, file, or data record that triggers an alert when accessed or used
Canary	Lightweight deception device or token that alerts on any interaction (Thinkst Canary platform)
Breadcrumb	Planted artifact (cached credential, bookmark, config file) leading attackers to deception assets
High-Fidelity Alert	Detection signal with near-zero false positive rate because no legitimate user should interact with deception assets
Decoy Network	Set of interconnected honeypots simulating a realistic network segment to observe attacker TTPs

Tools & Systems

• Thinkst Canary: Commercial deception platform offering hardware/virtual canaries and canary tokens
• Canarytokens.org: Free honeytoken generation service (DNS, HTTP, AWS keys, Word docs, SQL queries)
• Attivo Networks (SentinelOne): Enterprise deception platform with AD decoys and endpoint breadcrumbs
• HoneyDB: Community honeypot data aggregation platform for threat intelligence sharing
• T-Pot: Open-source multi-honeypot platform combining 20+ honeypot types in a Docker deployment

Common Scenarios

• Lateral Movement Detection: Attacker enumerates SMB shares and accesses honeypot file server — immediate high-fidelity alert
• Credential Theft Discovery: Mimikatz dumps honeytoken cached credentials — usage of fake account triggers alert
• Cloud Key Compromise: Stolen AWS canary token used from external IP — detects supply chain or insider compromise
• Ransomware Early Warning: Ransomware encrypts canary files on honeypot shares — early detection before production systems affected
• Insider Threat Signal: Employee accesses honeypot "salary database" — indicates unauthorized data exploration
