Bithumb hacked through employee system as South Korean financial firms face cyberattacks

Bithumb, South Korea's second-largest crypto exchange, disclosed a breach of its internal employee mobile system on Wednesday; no crypto funds were lost as the breached system runs separately from the trading platform. Personal information was taken in the attack; the exchange is analyzing the scope of the breach and whether member data was involved. This is Bithumb's second major incident this year after a February error that mistakenly credited customers with 620,000 BTC worth over $40 billion; South Korean financial firms faced multiple cyberattacks this week.
