[Video] Be careful with spam calls

Ringing for only 1-2 seconds and then hanging up. These seemingly harmless calls are making many people worried. What is behind it? A joke or bait for more sophisticated scams?

Be careful with spam calls.

According to authorities, scammers use call-in to verify active phone numbers , or collect the listener's voice . This data helps scammers classify by gender, age, and reaction - to create appropriate scam scenarios.

Some "bait calls" also trick users into calling back international numbers with high fees, causing losses of hundreds of thousands of dong.

Worse, the listener's voice can be recorded - to serve calls impersonating the police, banks or relatives.

The Cyber ​​Security Department and network operators advise: if you receive a spam call, ignore it and do not call back, especially from unknown numbers with a plus sign in front. If you are repeatedly bothered, block the number and report it to the hotline 5656.

A blink of the camera - seemingly harmless, but can be a lure for high-tech criminals.
Be alert, be conscious and protect yourself in the digital space.
