Reports: Up to 5 technical reports + executive summary.

What You Will Do

• Conduct white-box penetration testing of network-connected medical/aesthetic devices with embedded software.

• Assess current-generation devices (MILEO, LISA) built on a shared Windows 10 IoT Enterprise platform.

• Assess legacy devices (UPA, Stellar) on an earlier Windows IoT platform.

• Review software architecture, design documentation, REST APIs, and system credentials.

• Identify vulnerabilities, assess risks, and provide remediation recommendations.

• Deliver comprehensive technical reports (platform-level + product-specific) and an executive summary.
