Bithumb and Coinbase face security concerns – What did attackers actually access?

South Korea’s second-largest cryptocurrency exchange, Bithumb, is making headlines, but not for the right reasons. On the 28th of October, an outsider allegedly broke into Bithumb’s internal mobile groupware system, which employees use for communication and work-related activities, according to Yonhap News. Personal information was reportedly taken, although the exchange is still investigating whether customer data was included. However, Bithumb emphasized that the compromised system operates separately from its trading platform, meaning the breach did not provide direct access to customers’ crypto assets. At the same time, there were no cryptocurrency losses that had been reported so far. Other companies compromised in the past 12 hours This comes as asset manager Mirae Asset Global Investments and brokerage firm Daishin Securities were also among the affected companies.
