"Don't you talk straight? If you're arrested, do you think you'll have to be investigated before you get arrested?

"Speech is not cheap. I do not feel real. Go to the detention center. It is fun."

"It may sound strange, but Korea is the rule of law, and all those who work in judicial institutions are like this."

Voice phishing, which attempts to rip money after impersonating a prosecutor, grasping financial information and details using high-pressure speech, is gaining momentum.

According to the police, along with the use of high-pressure speech, the "abduction kidnapping fraud" technique of "send your son's kidnap and send money" is a classic but still often used.

A police officer said, "I often refer to arrests or arrests to scare and embarrass the victims, and deliberately treat them with high pressure." I'm going to charge you.'

At first glance, it seems like a poor trick, but experts say that when you actually answer a voice phishing call, you are often deceived.

Kwak Geum-joo, a professor of psychology at Seoul National University, said, "I received a phone call for voice phishing that impersonated the prosecution a few years ago, and I believed in the moment when I was scolding a bank account." I feel like I can be deceived.”

Professor Kwak said, "Inside humans, reason and emotion coexist." After hearing the words that they are going to be constrained, emotions can be shaken by fear or anxiety, and momentary lack of rational judgment."

A police officer said, "As a third party, you may think,'Why do you suffer from voice phishing?' If you experience it yourself, it's easy to be deceived.' In fact, there are occasional cases of damages by professionals such as judges, prosecutors, and professors.”

It is difficult to arrest a voice phishing organization that uses a cannon phone based in a foreign country.

Recently, new techniques such as exploiting malicious applications have appeared, and the damage is increasing year by year.

According to the Financial Supervisory Service, domestic voice phishing damage increased steadily from 119 billion won in 2016 to 231.1 billion won in 2017 and 440 billion won in 2018, and the amount of damage last year was 720 billion won, the highest ever.

That's an average of 1.84 billion won per day.

It is safe to call a government or financial institution that asks for personal information and money, whether it is voice phishing or not, and then call the nearest police station for help.

A police officer said, "There is no question that an investigative agency meets at a third place other than the government building or asks for sensitive personal information and money over the wire." There are many cases of threats, but never being arrested for hanging up on the phone."

It is also helpful to experience real crime techniques in advance.

On the website of'Voice Phishing Guardian' operated by the Financial Supervisory Service (http://phishing-keeper.fss.or.kr), it is said to be'the voice of the gnome' and the actual voice phishing voice recording is released.

If you suspect that you have already been involved in a voice phishing crime, you should contact the National Police Agency (☎ 112), the Financial Supervisory Service (☎ 1332), or a financial company promptly for assistance.
