🔒 How to Spot Phishing Emails
A comprehensive security guide to protect yourself from email-based cyber attacks
❌ The Threat is Real
Phishing attacks account for 90% of data breaches and cost organizations an average of $4.65 million per incident. Over 3.4 billion phishing emails are sent daily worldwide.
🎯 What is Phishing?
Phishing is a cyber attack where criminals impersonate trusted organizations to steal sensitive information like passwords, credit card numbers, or personal data. These attacks typically arrive via email, text message, or fake websites.
🚨 Critical Rule
When in doubt, don't click! It's always safer to verify independently than to risk a security breach. No legitimate organization will pressure you to act immediately via email.
🔍 Red Flags to Watch For
1. Suspicious Sender Information
| Red Flag | What to Look For | Example |
|---|---|---|
| Mismatched domains | Email claims to be from one company but domain doesn't match | Claims to be from "PayPal" but sent from noreply@payp4l.com |
| Generic addresses | Uses free email providers for official communication | support@gmail.com, billing@yahoo.com |
| Lookalike domains | Slight misspellings of legitimate domains | arnazon.com, microsooft.com, app1e.com |
| No display name | Only shows email address, no company name | Just x7k9m@suspiciousdomain.com |
2. Urgent or Threatening Language
⚠️ Common Pressure Tactics
- "Your account will be closed in 24 hours"
- "Immediate action required"
- "Verify your identity now or lose access"
- "Suspicious activity detected"
- "Click here to avoid account suspension"
3. Suspicious Links and Attachments
