Introduction

In healthcare cybersecurity, we often focus on perimeter defense, endpoint protection, and threat detection, but operational availability remains one of the most critical pillars of healthcare security. The recent case of Archbold Medical Center illustrates how medication inventory technology helped them avoid more than 500 stockouts, demonstrating the profound connection between operational visibility and security resilience.

For defenders, this isn't just about inventory management—it's about eliminating potential disruption vectors. When attackers target healthcare organizations, they exploit operational chaos. Medication shortages create exactly this chaos—diverting clinical staff, stressing IT resources, and creating environments where phishing and social engineering attacks thrive. As Andrea Jarzyniecki, executive director of pharmacy at Archbold, stated: "You can't fix what you can't see, and you can't effectively strategize if you don't have access to the necessary baseline information."

Technical Analysis

Affected Systems and Architecture

Medication inventory management systems in healthcare typically consist of:

• Automated dispensing cabinets (ADCs) running Windows-based embedded systems
• Inventory management applications connecting to ERP systems
• Mobile/scanning devices communicating via Wi-Fi
• Cloud-based analytics platforms

While this case doesn't involve a specific CVE or vulnerability, the broader threat landscape for healthcare inventory systems includes:

• Unpatched ADC systems (common CVEs in embedded Windows)
• Insecure APIs between inventory and ERP systems
• Weak authentication on mobile inventory devices
• Unencrypted data transmission between supply chain systems

Attack Scenarios Targeting Inventory Systems

Attackers could exploit inventory visibility gaps in several ways:

• Ransomware actors targeting pharmacy systems during critical shortages
• Nation-state threats exploiting supply chain chaos to deploy secondary payloads
• Insider threats leveraging inventory gaps for drug diversion

The risk is real: healthcare organizations with poor inventory visibility struggle to recover from attacks because they cannot prioritize restoration of critical medication workflows.

Executive Takeaways

1. Implement End-to-End Inventory Visibility: Deploy automated tracking systems across all medication touchpoints—pharmacy, ADCs, nursing units, and satellite locations. This visibility eliminates operational blind spots that attackers exploit during crisis events.

2. Secure Inventory Management Infrastructure: Treat ADCs, inventory scanners, and related systems with the same rigor as EHR and clinical systems. Implement application whitelisting, regular patching, and network segmentation for all inventory management devices.

3. Integrate Inventory Systems into Security Operations: Include inventory system anomalies in your SOC playbooks. Unusual inventory depletion patterns can indicate potential insider threats or supply chain attacks that may precede or accompany cybersecurity incidents.

4. Develop Business Continuity Plans Based on Inventory Data: Use real-time inventory intelligence to create data-driven response plans. When security incidents occur, prioritize protection of systems supporting medications with the lowest inventory buffers or highest clinical criticality.

5. Establish Cross-Functional Response Teams: Include pharmacy leadership in your incident response structure. The operational insights from professionals like Andrea Jarzyniecki are invaluable for triaging the business impact of security events and ensuring that remediation efforts align with clinical priorities.

Remediation

Securing Medication Inventory Systems

1. Conduct an Inventory System Risk Assessment: Map all medication inventory systems, identify data flows, and assess security controls. Pay special attention to:

   • ADC endpoints (typically Windows-based)
   • Inventory management servers and databases
   • API endpoints connecting to ERP/EHR systems
   • Mobile devices used for inventory management

2. Patch Management for Inventory Systems:

   • Establish a regular patching cadence for ADC systems (quarterly minimum)
   • Prioritize critical/CVSS 9.0+ vulnerabilities on inventory systems
   • Test inventory system patches in a non-production environment first

3. Network Segmentation:

   • Place inventory management systems in isolated VLANs
   • Implement strict firewall rules limiting ADC connectivity to only necessary inventory servers
   • Require VPN or zero-trust access for remote inventory management

4. Authentication and Access Controls:

   • Enforce MFA for all inventory management system access
   • Implement least-privilege access for pharmacy and nursing staff
   • Conduct quarterly access reviews for inventory systems

5. Monitoring and Detection: powershell

   Sample script to audit ADC system security posture

   Adapt to your specific ADC vendor and environment

   Check for critical services status on ADC systems

   $adcSystems = Get-Content -Path "ADCSystems.txt" foreach ($system in $adcSystems) {

       Write-Host "Checking security posture for $system" -ForegroundColor Cyan

   # Test connectivity
   if (Test-Connection -ComputerName $system -Count 1 -Quiet) {
       # Get service status (adapt service names to your ADC vendor)

           Get-Service -ComputerName $system | 
               Where-Object {$_.DisplayName -like '* McAfee *' -or 

                          $_.DisplayName -like '*CrowdStrike*' -or 
                          $_.DisplayName -like '*Windows Update*'} | 

               Select-Object MachineName, DisplayName, Status, StartType | 
               Format-Table

       # Check for critical Windows updates

           Invoke-Command -ComputerName $system -ScriptBlock {
               Get-HotFix | Where-Object {$_.InstalledOn -gt (Get-Date).AddDays(-30)} | 

               Sort-Object InstalledOn -Descending | 

                   Select-Object -First 5

       }
   } else {

           Write-Host "$system is unreachable - possible security issue" -ForegroundColor Red

   }

}

Vendor and Supply Chain Security

1. Conduct Third-Party Risk Assessments for all inventory management vendors, evaluating:

   • Security certifications (SOC 2, ISO 27001)
   • Breach history and disclosure practices
   • Data encryption standards
   • API security posture

2. Establish Service Level Agreements that include:

   • 24/7 security incident response
   • Defined notification timelines for security events
   • Patch SLAs aligned with industry benchmarks

3. Regular Penetration Testing of inventory management systems:

   • External penetration testing annually
   • Internal testing targeting ADC and inventory systems
   • API security testing for inventory-ERP integrations
