South Korean authorities have confirmed that 22 bitcoin, worth about $1.5 million, vanished from a cold wallet held by the Seoul Gangnam Police Station in a 2021 financial crime case.
Another Crypto Custody Failure Hits South Korean Authorities
According to local reporting, the bitcoin had been voluntarily surrendered in November 2021 during a virtual asset investigation and stored offline in a USB-type hardware wallet as court evidence. The device itself remains intact, but a nationwide audit in January 2026 revealed the funds had been transferred to an external blockchain address without any reported physical breach.
Blockchain analysis confirmed the outflow, stunning officials who believed cold storage would prevent remote access. The loss went undetected for more than four years, raising sharp questions about monitoring procedures for seized digital assets. At current market prices, the missing 22 BTC are valued at roughly $1.5 million.
The discovery follows a separate incident in August 2025, when the Gwangju District Prosecutor’s Office lost 320 BTC in what officials later described as a phishing-related breach. In that case, credentials were compromised during an asset handover, allowing funds to be drained while the hardware wallet remained untouched.
The Gyeonggi Bukbu Provincial Police Agency has launched an internal investigation into the Gangnam case, reviewing access logs, personnel handling, and possible technical vulnerabilities. Authorities are examining whether phishing, improper key management, or insider involvement played a role. No recovery of the funds has been reported.
The back-to-back incidents have intensified scrutiny of how South Korean law enforcement manages seized cryptocurrency. Cold wallets are designed to keep private keys offline, but they still depend on human procedures, audits, and secure key handling. When those fail, even “offline” assets can disappear.
With two high-profile losses now public, pressure is building for tighter custody protocols, multi-signature controls, and more frequent audits. For a country known for strict crypto enforcement, the message is clear: securing digital evidence requires more than locking a USB drive in a drawer.
