Hi, I’m Valentine 👋

Cybersecurity • Systems • IoT • Building in Public

I’m a cybersecurity-focused technologist documenting hands-on labs in IoT security, headless Linux systems, networking, and defensive research.

My work emphasizes:

• Understanding how systems actually behave
• Validating security assumptions at the network and OS level
• Learning by building, breaking, fixing, and documenting — publicly

---

🧠 What I’m Focused On

• 🛡️ Defensive security & blue-team fundamentals
• 🌐 Networking, USB gadget modes, RNDIS, SSH, and systemd
• 🖥️ Headless IoT devices & Linux internals
• 📡 Honeypots, logging, telemetry, and observability
• 📓 Clear documentation for reproducible security labs

---

🧪 Active Labs & Projects

🔹 Headless IoT Security Node

Repo: https://github.com/TheMarketfoxx/headless-iot-security-node

A foundational lab exploring:

• Headless Linux provisioning
• Network interfaces & device identity
• Logging, telemetry, and safe honeypot concepts
• Security tooling from a defensive mindset

Key skills: Linux, networking, logs, system validation

---

🔹 Pwnagotchi (Pi Zero 2 W) — USB RNDIS Lab (In Progress)

Repo: https://github.com/TheMarketfoxx/pwnagotchi-zero2w-usb-rndis-lab

A deep dive into:

• USB Ethernet (RNDIS) networking
• Headless provisioning and SSH onboarding
• systemd service management
• Real-world troubleshooting (drivers, IP conflicts, auth issues)

This project documents challenges, failures, and fixes step-by-step.

---

🔹 Honeypots & Security Tools

• Simple vulnerable honeypot experiments (controlled & authorized)
• Security log exporter tooling
• Focus on observation, not exploitation

---

🧰 Technical Skills (Applied)

• Operating Systems: Linux (headless), Windows
• Networking: TCP/IP, ARP, ICMP, USB Ethernet (RNDIS), SSH
• Security Concepts: Honeypots, logging, monitoring, threat awareness
• Languages: Python, JavaScript (ES6+), Bash
• Tooling: systemd, OpenSSH, PowerShell, Git, GitHub

---

📖 Building in Public

I intentionally document:

• What didn’t work
• Why it didn’t work
• How I proved the fix
• The security implications of each decision

This helps others learn how to think, not just what to copy.
