Red Flags to Watch For

URL Red Flags

❌ Suspicious Domain Names

Look for:

✅ amazon.com                 ← Legitimate
❌ amazon-security.com        ← Fake
❌ amazon.co.secure-login.com ← Suspicious
❌ amzn-customer-help.net     ← Imposter

Technique: Attackers add trusted names to malicious domains

❌ Strange Top-Level Domains (TLDs)

High-Risk TLDs:

Note: Not all are malicious, but be extra careful

❌ Excessive Subdomains

❌ secure.login.verify.paypal.malicious.com
         ↑                         ↑
    Looks legit              Actually this domain

Rule: The domain is what’s RIGHT BEFORE the final .com/.org/.net

❌ IP Addresses Instead of Domains

❌ http://192.168.1.1/login
❌ http://103.224.56.78/verify

Legitimate sites use domain names, not raw IPs

❌ Misspellings

❌ gooogle.com (extra 'o')
❌ micros0ft.com (zero instead of 'o')
❌ linkedln.com ('ln' instead of 'in')

Content Red Flags

🚨 Urgent Language

❌ "IMMEDIATE ACTION REQUIRED"
❌ "Account will be closed in 24 hours"
❌ "Unusual activity detected - verify NOW"
❌ "Limited time offer - expires TODAY"

Legitimate companies rarely use extreme urgency

🚨 Grammar and Spelling Errors

❌ "Dear valued costumer"
❌ "Your account have been suspended"
❌ "Click here for imediate access"

Professional companies proofread their communications

🚨 Generic Greetings

❌ "Dear Customer"
❌ "Dear User"
❌ "Dear Member"

✅ "Dear John Smith"
✅ "Hello Sarah"

Your bank knows your name

🚨 Requests for Sensitive Information

Legitimate companies NEVER ask via email/link for:
