South Korea Crypto Leak Highlights Institutional Security Gaps

A critical security lapse by South Korea's National Tax Service has exposed systemic vulnerabilities in government handling of digital assets. Officials inadvertently leaked a hardware wallet's recovery phrase in a public press release on February 27, resulting in the theft of $4.8 million in Pre-Retogeum (PRTG) tokens.

The breach occurred when investigators photographed a seized Ledger wallet alongside a notebook clearly displaying its 12- or 24-word recovery phrase—effectively publishing the cryptographic keys to the kingdom. Within hours, unidentified actors drained the wallet through multiple Ethereum address transfers tracked by Arkham Intelligence.

This incident marks the latest in a series of institutional crypto security failures, underscoring the urgent need for standardized custody protocols. While no major exchanges were directly involved, the case reinforces market demands for regulated custody solutions as digital asset adoption grows.
