Main intelligence Directorate of the South Korea suspects that North Korean hackers are behind the attacks on the most popular bitcoin exchange in the country.
According to the BBC this week, the national intelligence service (NIS) officially handed over the evidence to the prosecutors, who confirmed that the attack on the employee’s computer Bithumb since February, was carried out by North Korean hackers.
The incident was kidnapped crypto-currencies in the amount equivalent to 7.6 billion won (of 6.99 million U.S. dollars), as well as personal data of about 30,000 people.
The BBC reports that hackers demanded a ransom in the amount of 6 billion won ($5.5 million) in exchange for the destruction of the stolen information.
This is not the only case. In October, the staff of the National police Agency of South Korea confirmed that 25 employees from four different cryptocurrency exchanges have become targets for phishing attacks by hackers.
NIS also suspected that North Korea was involved in the attack on South Korean other cryptocurrency exchanger, Coinis, in September, and believes that both incidents may be part of a coordinated effort.
