South Korean exchange Coinrail reported that a June 2018 hacking incident led to the theft of several cryptocurrencies, including Pundi X, Aston, and NPER. The excerpt cites an estimated loss of about 40 billion Korean won and says Coinrail moved roughly 70% of its remaining holdings to cold wallets. Some stolen assets were reportedly frozen or subject to recovery-like measures through coordination with token issuers and other exchanges, including IDEX. KISA and police were investigating the cause, while the article notes Coinrail was a smaller exchange and had not obtained ISMS certification.
