How to Detect Phishing Sites: Red Flags and Verification Tools

"Your account has been compromised. Change your password immediately."

That link in the message — is it real? Over a 21-month period, 113,471 phishing URLs impersonating Naver (Korea's dominant portal) were detected. Phishing sites have become so sophisticated that even security-aware users can be fooled.

5 Red Flags of Phishing Sites

1. Check the URL Carefully

The most basic but most effective method.

Real Fake (examples)
google.com google-login.com
paypal.com paypal.com.verify-account.net
amazon.com arnazon.com (rn looks like m)
bankofamerica.com bankofamerica-secure.com

Key rule: The actual domain is what comes right before the TLD (.com, .org). Everything before that is a subdomain that anyone can create.

2. HTTPS Lock Icon

Having HTTPS doesn't guarantee safety — phishing sites can get SSL certificates too. But if a site asks for personal information without HTTPS, that's an immediate red flag.

3. Beware of Search Ads

Phishing through search engine ads is increasing. Scammers buy ads for terms like "bank login" to place their fake sites above legitimate results.

4. Urgency Tactics

"Your account will be deleted in 24 hours if you don't verify" — almost always phishing.

5. Excessive Data Requests

If a login page asks for your social security number, full credit card details, or CVV in addition to username and password, it's phishing.

Verification Tools

Korea-Specific: 보호나라 (Boho.or.kr)

KISA (Korea Internet & Security Agency) operates the 보호나라 service for URL verification:
