CYBER ASSISTANT– Empowering You Against Cyber Threats

In the modern digital era, the rapid growth of internet-based services has significantly increased the risk of cyber threats, particularly phishing attacks and weak cybersecurity practices among users. This paper presents the design and development of an intelligent cybersecurity web application, Cyber Assistant, that assists users in identifying and mitigating potential online threats through an interactive and user-friendly platform. The application is built using a client-server architecture, where the frontend is developed using React with TypeScript and Tailwind CSS, and the backend is powered by serverless functions using Supabase. A key feature is the implementation of an offline domain reputation system that simulates trust scoring using heuristic analysis, ensuring functionality even without internet connectivity. An integrated AI chat assistant enhances user engagement by providing contextual explanations, cybersecurity tips, and real-time guidance. The platform also includes a phishing simulation training module that educates users through scenario-based questions. Overall, this project bridges the gap between technical cybersecurity tools and everyday users by delivering an accessible, educational, and intelligent security solution.
