South Korea’s Bithumb said it detected abnormal withdrawals of the company’s coins from its cryptocurrency exchange.
The incident was found through the company’s abnormal-trading monitoring system in Seoul, it said. The exchange then halted cryptocurrency deposits and withdrawals and moved investor assets to a so-called cold wallet, which is disconnected from the internet and less vulnerable to theft, and all clients’ coins were safe, according to the exchange.
Bithumb said the incident was most likely caused by an “accident involving insiders†because an external intrusion path hadn’t been revealed after an inspection. It was hacked in June and the equivalent of $30.8 million of cryptocurrency was stolen.
