South Korea's NTS leaks wallet mnemonic and loses about $4.8M in seized PRTG tokens
South Korea's National Tax Service lost nearly $4.8 million in seized Pre-Retogeum tokens after an unredacted wallet recovery phrase appeared in a February 26 press release. Hackers allegedly funded the exposed wallet with ETH for gas fees and withdrew 4 million PRTG, marking the third major crypto custody lapse by South Korean authorities since January 2026.
