South Korean karaoke service, SOMESING, was targeted in a hacking incident during the weekend that resulted in the loss of hundreds of millions of SSX tokens.
As a result, crypto exchanges across South Korea have issued alerts to users and implemented provisional measures to reduce the risks to investors.
The aftermath of the attack has refocused attention on digital security risks in crypto exchanges.
Some have highlighted the Ethereum Foundation's possible legal scrutiny following its involvement in the Gatecoin hack.
The situation continues to develop as security reviews and investigations are ongoing.
