🎣 Advent of Cyber 2025 — Day 2 Write-Up
🧩 Social Engineering & Phishing
—
🧠 Social Engineering — Quick Overview
Social engineering is human hacking — manipulating people into making security mistakes like:
- Giving passwords
- Clicking malicious links
- Opening infected attachments
- Approving fake payments
- Sharing sensitive info
Attackers exploit urgency, fear, curiosity, authority, and carelessness.
It has nothing to do with hacking computers — it’s about hacking people.
🎯 Phishing
Phishing = social engineering through messages (email, SMS, QR codes, phone calls, DMs).
Goal:
👉 Make the victim click, open, or reply, so the attacker can steal credentials, money, or access.
🧠 Anti-Phishing Mnemonic: S.T.O.P.
1️⃣ First S.T.O.P. — Ask Yourself
- Suspicious?
- Telling me to click?
- Offering amazing deal?
- Pushing urgency?
2️⃣ Second S.T.O.P. — Do This
- Slow down
- Type the URL manually
- Open nothing unexpected
- Prove the sender
If you just follow this, you avoid 90% of phishing attacks.
