I use a lot of equipment called'multi-function devices' in my office.

There are print and copy/fax functions, but this multifunction device can also be hacked as long as it is connected to the Internet.

Recently, there have been cases where international phone bills have been bombed for this.



This is Park Ha-jung.

Guk-gyu, who runs a bookstore in Suwon, Gyeonggi-do, discovered that an international call fee of 1.5 million won was levied on his phone bill in July.



They made international calls 621 to Austria, 14 to Congo, and once to Uganda for 7 days.



Mr. Sun is surprised that he is charged a large amount of money even though he has never had anything.



When I checked the multifunction device, there was a record of sending a fax to a foreign country.

When I complained to the



telecommunications company

that I had

never sent a fax abroad, the telecommunications company assumed that there was a real trace of faxing, and that it was a hack.

line

When more cases similar to Sun's were received, the mobile phone company hacked more than 21,000 fax users last month. He warned of danger and went out.



Internet Security Agency has updated the security program of the multifunction device manufacturer, but it cannot guarantee complete security.

security experts have already damage cases reported Internet telephony as well In addition, he advises that multi-function devices can be hacked any number of times, and that if you use a router instead of connecting directly to the Internet, it will create an additional security wall and make hacking difficult.
