Securing U.S. Critical Infrastructure: Lessons from Stuxnet and the Ukraine Power Grid Attacks
Published in arXiv preprint, 2024
Analyzes the and incidents to reveal persistent vulnerabilities in U.S. critical infrastructure and proposes zero-trust and network segmentation strategies to improve resilience against future cyber threats.
Power Grid Cybersecurity: Policy Analysis White Paper
Published in arXiv preprint, 2024
Identifies systemic cybersecurity weaknesses in the U.S. power grid and proposes a dual strategy of enhanced information sharing and standardized cyber hygiene, alongside a unified national framework and standards to strengthen long-term resilience.
Silent Subversion: Sensor Spoofing Attacks via Supply Chain Implants in Satellite Systems
Published in AeroConf 2026 IEEE Aerospace Conference, 2025
Presents a NOS3-based simulation of supply chain–implanted malware, where a compromised satellite generates falsified telemetry that appears legitimate to ground control while retaining the ability to disable the targeted device.
SpyChain: Multi-Vector Supply Chain Attacks on Small Satellite Systems
Published in arXiv preprint, 2025
Demonstrates the first end-to-end simulation of multi-vector supply chain malware in NASA’s NOS3 environment, revealing how colluding satellite components can exfiltrate data and evade detection.
