- Performed security assessments of satellite user terminals and link protocols (Starlink, Thales Mission Link, Iridium sat-mobile, Inmarsat sat-mobile), capturing and analyzing RF traffic to identify protocol weaknesses and anomalous behaviors. - Built and operated an SDR lab (DragonOS) using HackRF One and USRP 321 / 410x platforms to demodulate, decode, and visualize satcom waveforms; integrated GNU Radio flows and custom scripts to streamline signal processing workflows.

• Researching end-to-end 5G network security, including core (5GC), RAN and edge components. • Investigating vulnerabilities across the 5G architecture and proposing strategies for threat detection and mitigation. • Emulated 5G networks (srsRAN + Open5GS) to simulate adversarial activity and monitor detection effectiveness.

- Completed foundational training in CTI methodologies (MITRE ATT&CK, cyber kill chain, diamond model frame- works). – Produced analytical RFI reports on state-sponsored APTs, ransomware groups, and evolving zero-day vulnerabilities. – Collaborated within the Cohort to refine threat reports and present Intelligence on high-profile cyber conflicts and geopolitical threats.

• Assisted in configuring ACLs, NAT, and subnetting to simulate secure network environments. •Maintained documentation for physical and virtual lab infrastructure.
