💡 WHAT THIS TEACHES: EMAIL HYGIENE, TYPOSQUATTING & ATTACK VECTORS

Over 90% of organizational breaches originate via phishing. Attackers employ Typosquatting (e.g. m1crosoft.com or paypa1.com), Display Name Spoofing (setting a trusted label with an untrusted email), Double Extensions (e.g. invoice.pdf.exe), and high-urgency psychological triggers to induce panic clicks. Examining raw headers, link target URIs, and attachment hashes is fundamental for SOC Tier-1 triage.
