Those who are dreaming for a steady rise in the value of virtual money investment, as well as the bitcoin, which is worth over 20 million won per coin, prices of virtual money such as etherium, light coin and dash are skyrocketing. Actually, as of 11:00 am on the 19th, the price per liter of the etherium is KRW 900,000, which is 8000% higher than last year. It is worrisome that phishing and hacking techniques that mislead the public with social engineering techniques are becoming polarized because of such a surge of virtual money.

According to the security industry on December 19, spam e-mails related to the recruitment of a branch manager for a virtual money exchange targeting an unspecified number of people are pouring. Mail recruited branch managers across the nation who will lead new innovations in virtual currency and bitcoin based on "the three largest exchanges in Japan and the largest exchange in China". When users access a site linked to the bottom of the mail, you will be directed to a site where you can write your name, phone number, email address, and location. The spam e-mails are estimated to be a multi-level fraud scheme, similar to fraudulent organizations such as the "virtual" currency investment agency "Ether Trade", which police arrested in July. These methods are said to give profits by virtual money, to investors, and to give a certain percentage of the investment when bringing new members in pyramid fashion. An official of the cyber security department of the police said, "I cannot conduct a criminal investigation based on the contents of the e-mail only through the contents of the e-mail, but there seems to be a problem from the collection of personal information.

According to the Korea Internet & Security Agency (KISA), hackers will be more likely to attack hacking, which is relatively easy to attack, profitable virtual currency exchanges or users` bit coin purses, rather than attacking the block chain itself, which is a bit coin authentication system. Malicious code that steals a virtual wallet in a user`s PC has already been circulated on the Web, and techniques for deceiving a specific organization or a person and aiming for virtual money have been mobilized.

A site is followed up by this, and exchanges such as Bitcoin, Coin and Won are suffering after a phishing site that purports personal information and virtual money by pretending to be Kobit in Korea`s first virtual currency exchange in August. Therefore, Korbit is taking measures to prevent money withdrawal from the virtual address on the 14th. It is also popular to steal virtual money after stealing an investor`s authorization number by impersonating an exchange call center. Even on the 14th, "Spear phishing (specific target) hacking" e-mails, which purported to be KISA, were circulated to officials of the virtual currency exchanges. "The virtual money market needs to introduce a security system similar to that of the banking system in accordance with the size of the transaction with the rapidly increasing number of users," said Kwon Hwang-seong, vice president of the KISA Infringement Response. "Individual users should pay attention to personal information management such as account ID and password." said.
