The South Korea police has begun to extensively investigate Bithumb's $12.6 million crypto hack, which the major cryptocurrency exchange previously described as a possible inside job. On March 30, the Bithumb team said in an official statement that it suspects the breach to have been conducted by insiders within the company. "As a result of the internal inspection, it is judged that the incident is an “accident involving insiders," Bithumb said. This week, the South Korea police has started to investigate potential external servers and IP addresses that may be associated with the security breach, opening the possibility that the breach involved outsiders. A Bithumb spokesperson told MoneyToday, a local publication, that no customer funds were stolen during the incident and that only corporate funds were stolen. Customer funds stored in cold wallets remain safe.
