According to South Korea's "Maeil Economy", South Korea's National Tax Service mistakenly disclosed the mnemonic phrase of the hardware wallet in full in the news photo when releasing the results of the seizure of crypto assets. Blockchain data shows that approximately 4 million PRTG tokens within the relevant wallets were subsequently transferred, valued at approximately $4.8 million. Experts pointed out that the leakage of the mnemonic phrase is equivalent to handing over control of the wallet, which is a serious security management mistake.
