身に覚えのないリンク（URL）を開かないようにしよう | 国民のためのサイバーセキュリティサイト

This page explains the importance of not opening unfamiliar links in emails and SMS messages. Phishing scams and malware infections increasingly occur through links in electronic mail and SMS, with sophisticated attacks impersonating financial institutions and delivery companies. Users should remain vigilant even with messages from acquaintances or business partners. Macro viruses embedded in Office files also pose risks, as security software may not detect them. Users should never enable suspicious macros. It is essential to exercise extreme caution when opening links in emails and attachments.
