Cold wallets aren’t invincible—human error still opens the door to millions.

💥The Myth of the "Safe" USB: South Korea’s State Custody Crisis 🇰🇷📉

It’s becoming a pattern. For the second time in months, South Korean authorities have proven that holding the physical device is only half the battle. 22 $BTC (~$1.5M) was just drained from a cold wallet held by Seoul’s Gangnam Police since 2021 - without the USB even leaving the evidence locker.

💡The Failure Points:

◾ The "Invisible" Drain: The physical USB remained intact, yet the digital assets were siphoned. This points to a massive breach in either private key management or an inside job.

◾ The Domino Effect: This comes right after the Gwangju District Prosecutors lost 320 BTC to a simple phishing site during a routine inspection.

◾ The Hard Truth: Cold storage isn't a magic shield; it’s a tool. If the human operating it clicks a malicious link or leaks a key, the "cold" status is irrelevant. At a state level, the lack of multi-sig protocols and audited governance is no longer just a lapse—it’s a systemic risk.

Bottom Line: Self-custody is about sovereignty, but without rigorous operational security (OpSec), it’s just a high-stakes waiting game for hackers.
