Detecting and Preventing Phishing Attacks
Identify phishing attempts across email, SMS, and web, with practical prevention strategies.
Key Takeaways
- Phishing remains the number one attack vector for security breaches.
- Check the sender's actual email address (not just display name) — hover over it to see the real domain.
- Smishing (SMS phishing) uses urgency to bypass your usual caution — "Package delivery failed, click here." Vishing (voice phishing) impersonates banks, government agencies, or tech support.
- Phishing sites can look identical to legitimate sites.
- Enable MFA on all accounts — even if credentials are phished, attackers can't access your account without the second factor.

The Phishing Landscape
Phishing remains the number one attack vector for security breaches. Modern phishing goes beyond obvious spam — sophisticated attacks use AI-generated content, cloned websites, and social engineering to trick even security-aware users. Understanding current techniques is your best defense.
Email Phishing Red Flags
Check the sender's actual email address (not just display name) — hover over it to see the real domain. Look for urgency language ("Your account will be suspended in 24 hours"). Hover over links before clicking to verify the destination domain. Watch for subtle domain misspellings (paypa1.com vs paypal.com). Be suspicious of unexpected attachments, especially .exe, .zip, and Office files with macros.
SMS and Voice Phishing
Smishing (SMS phishing) uses urgency to bypass your usual caution — "Package delivery failed, click here." Vishing (voice phishing) impersonates banks, government agencies, or tech support. Never click links in unexpected text messages. If a caller claims to be from your bank, hang up and call the number on your card directly.
Website Clone Detection
Phishing sites can look identical to legitimate sites. Always check the URL in the address bar — look for the correct domain with valid HTTPS. Use a password manager — it won't autofill credentials on a cloned domain. Check the SSL certificate details for suspicious issuers. Be wary of sites reached through email or SMS links rather than direct navigation.
Prevention Strategy
Enable MFA on all accounts — even if credentials are phished, attackers can't access your account without the second factor. Use a password manager that only autofills on legitimate domains. Keep browsers and email clients updated for the latest phishing detection. Report phishing emails to your IT department and email provider. Consider DNS-level protection services that block known phishing domains.
