[Connection Test] What to Check When You Receive a Suspicious Text Link
This is a test article for verifying the connected drafting, validation, and publishing workflow. It summarizes basic actions for handling suspicious text-message links using official guidance.
This article is a test of the connected web publishing workflow.
Before opening a link
Do not immediately open a URL in an unexpected message. Even if the sender claims to be a government agency or financial institution, verify the request through the organization’s official website or published phone number rather than the contact details in the message.
- Compare the message URL with the organization’s official domain
- Watch for requests for passwords, verification codes, or payment details
- Stop if you are asked to install a remote-control or unfamiliar app
How to report a suspicious message
KISA provides guidance through its 118 hotline, device spam-reporting functions, and the Smishing and Phishing Check service in the BohoNara KakaoTalk channel. If money may have been lost, promptly contact the relevant financial and law-enforcement reporting channels.
If you opened the link or entered information
- Stop entering information and do not install additional apps.
- Change affected account passwords from a trusted device and review multi-factor authentication.
- If an app may have been installed, run a mobile security check or visit an authorized service center.
- Review payments and transfers and file the appropriate reports if loss is suspected.
Opening a link alone does not prove that malware was installed. However, installing an app or entering personal or financial information warrants immediate review and protective action.
