South Korea tax agency posts seized wallet phrase and $5 million is stolen

Mar 3rd 2026

Images in an official press release revealed a seized wallet recovery phrase, enabling a thief to drain roughly $5 million and prompting an internal review and promises of tighter controls.

  • National Tax Service mistakenly published images showing a seized wallet recovery phrase in a press release, according to reports.
  • About $5 million in cryptocurrency was drained from the wallet within hours after the images circulated online.
  • Authorities have no clear suspects and recovering funds on the blockchain is difficult without the thief using a regulated exchange, experts say.
  • Police say they will strengthen internal controls and staff training after the leak was disclosed.
  • The incident follows other reported custody failures by South Korean law enforcement earlier this year involving missing seized bitcoin.
