Network reconnaissance
Related work and learning, in one place.
Network discovery and service inspection. Nmap, Zenmap, and Scapy appear in the supporting work where used.
Projects
Self-Hosted Infrastructure & Email Deliverability
I run a Debian homelab and web/mail infrastructure serving more than a dozen domains. I corrected DKIM, SPF, DMARC, and reverse DNS after outbound mail failed authentication at Gmail and Microsoft, restoring authentication and delivery across the hosted domains.
Network and audio experiments
Python experiments with scapy and nmap for network reconnaissance and packet inspection, plus audio-based information hiding and signal processing. I also used Kali Linux and analyzed public password-breach datasets in educational work on owned systems or with consent.
Embedded-device investigation
An independent 2023 investigation used Nmap/Zenmap for service discovery and Telnet for embedded Linux inspection. I imaged SD media and used Disk Drill to inspect recovered files and export a deleted thumbnail.
