Honeypots are a high-confidence supplementary layer, not a replacement for EDR, network monitoring, and backup protection.\n\n## Prerequisites\n\n- File server or NAS infrastructure where canary files can be deployed\n- Windows File Server Resource Manager (FSRM) or equivalent file activity monitoring\n- Thinkst Canary or similar deception platform (optional, for advanced deployment)\n- SIEM platform for centralizing honeypot alerts\n- Administrative access to deploy canary files across file shares\n- Network segment for honeypot systems (if deploying full honeypot servers)\n\n## Workflow\n\n### Step 1: Deploy Canary Files on File Shares\n\nPlace canary files in strategic locations that ransomware will encounter during encryption:\n\n```powershell\n# Deploy canary files across all file shares\n# Files are named to appear early in alphabetical and directory order\n# Ransomware typically encrypts alphabetically or by directory traversal\n\n$shares = @(\"\\\\fileserver01\\finance\", \"\\\\fileserver01\\hr\", \"\\\\fileserver01\\engineering\")\n$canaryNames = @(\n    \"!_IMPORTANT_DO_NOT_DELETE.docx\",\n    \"000_Budget_2026_FINAL.xlsx\",\n    \"_Confidential_Employee_Records.pdf\",\n    \"AAAA_Quarterly_Report.docx\"\n)\n\nforeach ($share in $shares) {\n    foreach ($name in $canaryNames) {\n        $targetPath = Join-Path $share $name\n        # Create a legitimate-looking file with canary content\n        # The file contains a unique token that triggers on access\n        $content = \"This document contains confidential financial data.`n\"\n        $content += \"Q4 2025 Revenue: $42.3M | Q1 2026 Forecast: $45.1M`n\"\n        $content += \"Prepared by: Finance Department`n\"\n        Set-Content -Path $targetPath -Value $content\n        # Set file as hidden system to avoid user interaction\n        $file = Get-Item $targetPath\n        $file.Attributes = [System.IO.FileAttributes]::Hidden\n    }\n}\n\n# Also deploy in subdirectories (ransomware traverses recursively)\n$subDirs = Get-ChildItem -Path \"\\\\fileserver01\\finance\" -Directory -Recurse | Select-Object -First 20\nforeach ($dir in $subDirs) {\n    $canaryPath = Join-Path $dir.FullName \"!_Budget_Summary.xlsx\"\n    Set-Content -Path $canaryPath -Value \"Canary file for ransomware detection\"\n    (Get-Item $canaryPath).Attributes = [System.IO.FileAttributes]::Hidden\n}\n```\n\n### Step 2: Configure File Integrity Monitoring on Canary Files\n\n**Windows FSRM approach:**\n\n```powershell\n# Configure FSRM to monitor for ransomware file extensions\n# and canary file modifications\n\nInstall-WindowsFeature -Name FS-Resource-Manager -IncludeManagementTools\n\n# Create file screen for known ransomware extensions\n$ransomExtensions = @(\n    \"*.encrypted\", \"*.locked\", \"*.crypto\", \"*.crypt\",\n    \"*.locky\", \"*.cerber\", \"*.zepto\", \"*.thor\",\n    \"*.aesir\", \"*.zzzzz\", \"*.wallet\", \"*.onion\",\n    \"*.wncry\", \"*.wcry\", \"*.lockbit\", \"*.BlackCat\",\n    \"*.ALPHV\", \"*.rhysida\", \"*.play\"\n)\n\n# Create file group for ransomware extensions\nNew-FsrmFileGroup -Name \"Ransomware_Extensions\" -IncludePattern $ransomExtensions\n\n# Create file screen template\nNew-FsrmFileScreenTemplate -Name \"Ransomware_Screen\" `\n    -IncludeGroup \"Ransomware_Extensions\" `\n    -Active:$false  # Passive mode: alert without blocking\n\n# Apply to all monitored shares\n$monitoredPaths = @(\"D:\\Shares\\Finance\", \"D:\\Shares\\HR\", \"D:\\Shares\\Engineering\")\nforeach ($path in $monitoredPaths) {\n    New-FsrmFileScreen -Path $path -Template \"Ransomware_Screen\"\n}\n```\n\n**Canary file modification monitoring with PowerShell FileSystemWatcher:**\n\n```powershell\n# Real-time canary file monitoring service\n$canaryPaths = @(\n    \"D:\\Shares\\Finance\\!_IMPORTANT_DO_NOT_DELETE.docx\",\n    \"D:\\Shares\\HR\\000_Budget_2026_FINAL.xlsx\",\n    \"D:\\Shares\\Engineering\\_Confidential_Employee_Records.pdf\"\n)\n\n$watcher = New-Object System.IO.FileSystemWatcher\n$watcher.Path = \"D:\\Shares\"\n$watcher.Filter = \"*\"\n$watcher.IncludeSubdirectories = $true\n$watcher.EnableRaisingEvents = $true\n\n$action = {\n    $path = $Event.SourceEventArgs.FullPath\n    $changeType = $Event.SourceEventArgs.ChangeType\n    $timestamp = $Event.TimeGenerated\n\n    # Check if modified file is a canary\n    $isCanary = $false\n    foreach ($canary in $canaryPaths) {\n        if ($path -eq $canary) { $isCanary = $true; break }\n    }\n\n    if ($isCanary -or $changeType -eq \"Renamed\") {\n        $alertMsg = \"RANSOMWARE ALERT: Canary file modified!

Forward honeypot alerts to SIEM and trigger containment\n\nimport json\nimport requests\nimport logging\nfrom datetime import datetime\n\nSIEM_WEBHOOK = \"https://siem.company.com/api/alerts\"\nNAC_API = \"https://nac.company.com/api/v1/quarantine\"\nEDR_API = \"https://edr.company.com/api/v1/isolate\"\n\ndef send_ransomware_alert(source_ip: str, canary_path: str, action: str):\n    \"\"\"Send high-priority alert to SIEM and trigger automated containment.\"\"\"\n    alert = {\n        \"timestamp\": datetime.utcnow().isoformat(),\n        \"severity\": \"CRITICAL\",\n        \"category\": \"Ransomware -

Windows Server role that monitors file operations and can screen for ransomware extensions |\n| **Deception Layer** | Security architecture layer using decoy assets to detect threats with near-zero false positive rates |\n| **File System Watcher** | System service that monitors real-time file system changes (creation, modification, deletion, rename) |\n\n## Tools & Systems\n\n- **Thinkst Canary**: Commercial deception platform providing canary appliances (emulate servers) and canary tokens (trackable documents)\n- **Canarytokens.org**: Free service from Thinkst for generating basic canary tokens (Word docs, PDFs, URLs, DNS)\n- **OpenCanary**: Open-source honeypot daemon that emulates common services (SMB, RDP, SSH) and logs access attempts\n- **FSRM (File Server Resource Manager)**: Windows Server built-in tool for file screening, quota management, and ransomware extension detection\n- **Elastic Endpoint**: Uses canary files internally for ransomware protection, triggering behavioral alerts on canary modification\n\n## Common Scenarios\n\n### Scenario: Early Detection of BlackByte Ransomware via Canary Files\n\n**Context**: A retail company deploys canary files across 200 file shares and 3 honeypot shares. At 3:00 AM on a Saturday, the canary monitoring system generates 47 alerts in rapid succession as canary files across 12 shares are modified within 90 seconds.\n\n**Approach**:\n1. Canary file alert triggers automated containment: source workstation (10.2.8.55) quarantined via NAC within 30 seconds\n2. SIEM correlation shows the source workstation had EDR alerts for PsExec execution 2 hours earlier (missed by overnight SOC)\n3. Additional canary alerts from 3 other workstations indicate the ransomware is spreading via scheduled tasks\n4. IR team isolates the affected VLAN, preventing encryption of the remaining 188 file shares\n5. The 12 affected shares are restored from immutable backups within 4 hours\n6. Estimated damage prevented: $2.3M in downtime and recovery costs based on the 95% of shares protected\n\n**Pitfalls**:\n- Placing canary files only in root directories where ransomware may skip them by targeting subdirectories first\n- Using obvious canary names that sophisticated ransomware may recognize and avoid\n- Not testing canary alerting end-to-end, discovering during an actual incident that alerts are not reaching the SOC\n- Generating excessive canary alerts during legitimate file migrations or antivirus scans, causing alert fatigue\n\n## Output Format\n\n```\n## Ransomware
