"Gyeongnam Ansim Link" is a mobile security app that automatically scans links encountered in daily life—such as those in text messages, KakaoTalk, Telegram, LINE, and web browsers—and immediately notifies you if they are suspected of being smishing or phishing.

To help you double-check before clicking a link, it prevents damage by displaying a warning window on the screen when a suspicious URL is detected.

▶ Why is it necessary?

Recently, smishing and phishing have been spreading through various channels, including text messages, messengers, shortened URLs, and fake delivery or financial notifications. Clicking on just one wrong link can lead to personal information leakage or financial damage.

Gyeongnam Ansim Link extracts links in the background and checks for risks while you continue using the apps you normally use. You can use it immediately after installation without separate registration.

▶ Key Features

① Automatic SMS Link Scanning

It searches for URLs in received and saved text messages to check for smishing. It does not upload the full content of the message to the server; it uses only the URLs necessary for the scan.

② Messenger Notification Link Scanning

Analyzes links included in messenger notifications from services such as KakaoTalk, Telegram, and LINE in real-time. The entire conversation is not collected or transmitted.

③ Real-time Browser Address Bar Scanning

Reads only the address bar of major browsers such as Chrome, Samsung Internet, Whale, and Firefox to check the URL of the page currently being visited. It does not read the web page body or input content.

④ Immediate Warning Notification

If a link is determined to be dangerous, a warning window (overlay) is displayed even while using other apps. It shows the source of the link (text message, messenger, web, etc.) along with a message preview.

⑤ Detection History (Timeline)

Only links suspected of being smishing are recorded on the device. Up to 200 records are stored locally for a maximum of 30 days, and can be viewed or deleted from the app at any time.

⑥ Trusted Domain Settings

You can reduce unnecessary warnings by registering frequently used legitimate sites (company intranet, banks, shopping malls, etc.).

⑦ Night/Silent Mode / Pause Protection

You can turn off vibration, sound, and alert windows during your desired time slots, or temporarily pause protection for 1 hour or for the entire day.
