Silent Subversion Completed!
Published:
The second major milestone in my small-satellite cybersecurity work is complete — Silent Subversion, now submitted to the 2026 IEEE Aerospace Conference.
This project builds directly on SpyChain but focuses on an even subtler problem: when a satellite’s own sensors can no longer be trusted.
Finished SpyChain!
Published:
After nearly a year of design, implementation, and refinement, the SpyChain project is complete.
SpyChain represents the first full simulation of coordinated, multi-component supply-chain malware within a small-satellite environment, implemented entirely inside NASA’s NOS3 framework.

Silent Subversion: Sensor Spoofing Attacks via Supply Chain Implants in Satellite Systems
Published in In Progress, 2025
Presents a NOS3-based spoofing simulation where a compromised satellite component generates false telemetry accepted as legitimate by ground control.
SpyChain: Multi-Vector Supply Chain Attacks on Small Satellite Systems
Published in arXiv preprint arXiv:2510.06535, 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.
