South Korean prosecutors (specifically the Gwangju District Prosecutors’ Office) discovered that a large amount of Bitcoin that had been seized as criminal assets is now missing. Authorities believe this occurred due to a phishing attack during a routine security check, which led to the theft of the private keys controlling the Bitcoin wallets.
Local media and internal sources estimate the missing Bitcoin’s value at about 70 billion Korean won, roughly $47–$49 million USD.
Internal audit showed the coins were likely lost via a phishing attack during official storage, according to local media reports.
