Only seven out of the 21 cryptocurrency exchanges have passed the government’s security test. They are Doonamu, Bithumb, Gopax, Korbit, Coinone, Hanbitco, and Huobi.

The Ministry of Science and ICT and the Korea Internet Security Agency announced the test result Thursday after surveying 21 major exchanges from September through December.

Each of the 14 ‘failed’ exchanges has yet to improve 51 out of the 85 security codes. The seven of them could not undergo the test because they suspended business and their testing result was based on the survey made from January through March last year.

The seven ‘successful’ exchanges passed all of the 85 security codes. In the January-March inspection, each of them failed to pass the 39 codes on average.

The ministry and the KISA would continue to monitor the security safety of the exchanges to protect investors from hackers.

In the meantime, the ministry and the KISA said the four exchanges, including Doonamu, Bithumb, Korbit, and Coinone, have successfully passed through the Internet Security Management System (ISMS).

Gopax also got the MSMS certificate while the other unnamed exchanges are undergoing inspection for the certification.

The ministry and the KISA advised investors to be alert against the exchanges, except for the seven certified ones.

The ‘failed’ exchanges might be the target of hackers, which would deal financial damage to investors, they said.

Even the seven ‘certified’ exchanges should continue to upgrade security against hackers, they added.
