Production Solution & Architecture

Phishing is a broad, untargeted attack where malicious actors send mass emails (e.g., "Your PayPal account is locked") to millions of random people simultaneously. The goal is sheer volume, hoping a small fraction of recipients will mistakenly click the malicious link and enter their credentials. Spear Phishing is a highly targeted attack directed at a specific individual or organization. Attackers conduct deep reconnaissance (LinkedIn, social media) to craft a highly convincing, personalized message (e.g., an email appearing to come from the CEO to the CFO requesting an urgent wire transfer to a specific vendor). It is much harder to detect and is often the entry point for major corporate breaches.
