Overview
- Police are investigating after the National Tax Service’s Feb. 26 press photo exposed a wallet recovery phrase, enabling the transfer of 4 million PRTG tokens worth about 6.9 billion won ($4.8 million).
- Blockchain analysis by Hansung University’s Cho Jae-woo shows the tokens moved to a single wallet between 7:43 p.m. and 8:13 p.m. that day and were moved again the next day.
- The NTS apologized, requested a police probe, and said it has updated its seizure and storage manual and will train staff to prevent credential exposure.
- The National Police Agency’s cyber unit received an online report from a person claiming they accessed the funds after seeing the code and returned them, a claim investigators will verify against transaction records.
- Authorities outlined tighter custody controls including two designated officials, split recovery‑phrase and password control, monthly balance checks, and plans to entrust seized crypto to specialized custodians, following earlier scrutiny over a 22 BTC loss in the Gangnam case.
