A cyber hacking that overloads the server by sending a lot of data at once is called a DDoS attack.
It is simple yet so powerful that it is a cybercrime that even corporations suffer from.
However, recently, the number of cases of DDoS attacks like this in PC rooms in the metropolitan area is increasing.
Reporter Kang Min-kyung found out.

This is a PC room in Gunpo-si, Gyeonggi-do.
A female customer calls an employee to complain that the computer has stopped.
Soon following, the students on the other side shouted and looked around.
On the other side, middle-aged men leave their seats altogether.
Computers that have been attacked by DDoS are all shut down.
The president, who has been running this PC room for three years, complains that this is already the second time in a month.

There are not one or two PC rooms suffering from DDoS attacks.
This PC room in Suwon has also been constantly being attacked by DDoS since two months ago. The robbery was so severe that it had to be closed for a full month or so recently.

In the end, there have been cases where the company went bankrupt following taking a loss of hundreds of millions of won.
But there is no good solution.
This is because DDoS attacks are a method of inducing server overload by suddenly pouring large amounts of data, so there is no fundamental blocking method.
It is possible to change the IP address targeted by the Internet provider by requesting it, but it is useless if the worker visits the server and repairs the server one by one, and even hacking and attacking the changed IP address once more is useless.
However, it is difficult to expect government support or countermeasures.
Although the Korea Internet & Security Agency operates a system called ‘Cyber Shelter’ that blocks DDoS attacks by bypassing traffic for a certain period of time, PC rooms are not eligible for support.

In the end, the business owners who suffered the damage turned to the police cybercrime for help.
However, due to the nature of the investigation that traces back IP, it takes at least several months to catch the criminal.
In the meantime, the worries of the self-employed who have to roll their feet for a living are getting deeper and deeper.
