South Korea's $4.8M OpSec Catastrophe: How the National Tax Service Photographed Its Own Seed Phrase and Got Robbed Twice in 48 Hours
Imagine raiding a tax evader's apartment, seizing four hardware wallets, and then publishing a triumphant press release showing the recovered evidence — with the wallet's seed phrase clearly visible in the photo. Now imagine a thief drains the wallet within hours, returns the tokens as a warning, and a second thief steals them again before your agency can react.
That is not a crypto Twitter thought experiment. That is exactly what happened to South Korea's National Tax Service (NTS) in late February 2026 — a blunder that cost the government roughly $4.8 million in seized Pre-Retogeum (PRTG) tokens and exposed how unprepared most state agencies are to hold digital assets they increasingly confiscate.
