In November 2025, Czzsmn02p07c349d developed a cross-platform security testing payload suite for the hak5/usbrubberducky-payloads repository, focusing on exfiltration of SSH keys and certificates across Windows, macOS, and Linux. Leveraging skills in scripting, payload development, and cybersecurity, they implemented a proof-of-concept that automates data exfiltration scenarios for penetration testing and training simulations. The work included creating payload generation scaffolding and delivering a payload.txt artifact using DuckyScript and Shell scripting. While the contribution was limited to a single feature over one month, it established a technical foundation for future automated security assessments and cross-OS data-exfiltration simulations.
Month: 2025-11 — hak5/usbrubberducky-payloads delivered a new cross-platform security testing payload suite and PoC, focused on exfiltration of SSH keys and certificates across multiple operating systems. The work enhances cross-OS testing capabilities, demonstrates secure payload generation, and provides a foundation for security assessments and training simulations.
