A leading crypto-coin exchange has halted trade after declaring that hackers had stolen some of the digital currencies it stored.
Seoul-based Bithumb said that 35bn won (£24m; $31.6m) worth of cyber-cash had been “seized” overnight, adding that it would fully compensate affected customers.
The values of Bitcoin, Ethereum and Ripple all fell on the news.
It is the second time in less than a year that Bithumb has been breached.
South Korea’s spy agency later accused North Korea of being responsible after the stolen information was used to carry out scams.
Bithumb notified a local regulator – the Korea Internet and Security Agency – of the latest attack, shortly before alerting the public via social media.
