SEOUL - South Korea's spy agency said North Korean hackers were behind attacks on cryptocurrency exchanges this year in which some 7.6 billion won ($6.99 million) worth of cryptocurrencies were stolen, a newspaper reported on Saturday.
The cyber attacks attributed to North Korean hackers also included the leaking of personal information from 36,000 accounts from the world's busiest cryptocurrency exchange Bitthumb in June, South Korea's Chosun Ilbo reported, citing the country's National Intelligence Service (NIS).
Attacks also included the theft of cryptocurrencies from accounts at exchanges Yapizon, now called Youbit, and Coinis in April and September, it said.
