Worked on enhancing the advanced captive portal in the airgeddon repository by integrating Zyxel MAC vendor information and implementing color-coded device identification. Focused on improving the user interface for network administrators, the update added Zyxel MAC prefixes to the cp_router_colors array within the airgeddon.sh script, enabling immediate visual differentiation of Zyxel routers in portal data. Leveraged skills in network security, scripting, and captive portal technologies, ensuring compatibility with existing data flows and maintaining display integrity. The work was delivered as a single, traceable feature commit, reflecting a targeted and maintainable approach to feature development within a complex shell scripting environment.
