South Korea’s NTS Blunder Triggers $480 Million Crypto Theft After Shocking Photo Leak
A Massive Security Fail Shakes South Korea
In a shocking event, South Korea’s National Tax Service (NTS) lost control of crypto worth $480 million. This happened because of a simple mistake in a press release. The agency shared photos of seized cold wallets, but the images showed the secret recovery codes. Thieves used these codes to steal the assets fast.

What Led to the $480 Million Crypto Theft?
On February 26, 2026, the NTS put out a press release. They wanted to brag about seizing assets from a tax dodger. The release had clear photos of four USB cold wallets. These are offline devices that keep crypto safe from hackers.
But here’s the problem: the high-res photos showed the mnemonic codes on the wallets. A mnemonic code is a 12-24 word phrase. It’s like the master password for your crypto wallet. Anyone with it can access your funds from anywhere, without the USB.
Just one day later, thieves drained the wallets. They took 4 million PRTG coins, worth about 69 billion KRW or $480 million USD. The money went to unknown accounts. It was a quick and clean heist.
Quick Response from Authorities
The NTS acted fast. On February 27, they asked police to investigate. By February 28, the National Police Agency’s cyber team started work. They are tracking the stolen coins on the blockchain.
Police focus on who saw the press photos. Thieves might face charges for hacking and fraud under Korean laws. Blockchain tools help trace the funds through exchanges and wallets.
Understanding Cold Wallets and Mnemonic Codes
Cold wallets are popular for safety. They stay offline, away from internet hacks. But the mnemonic seed phrase is the weak spot. It lets you recover the wallet on any device.
- Seed Phrase Basics: 12-24 random words.
- Power: Full control over private keys.
- Risk: If leaked, funds are gone forever.
The NTS photos made this private info public. It was like leaving your house keys on the street.
Not the First Time for South Korea Agencies
This isn’t new. Last month, Gwangju prosecutors lost seized Bitcoin but got it back. Gangnam Police lost 2.1 billion KRW in Bitcoin from custody. The suspect was caught, but it shows a pattern.
Government teams lack crypto know-how. They treat digital assets like cash, but crypto needs special care.
Why Did This Happen?
The NTS wanted to show success. They seized USBs and luxury bags from a tax evader and their spouse. But no one checked the photos for leaks.
Questions remain: Was there no review? Did staff not know about mnemonic risks? This cost them dearly.
Big Lessons for Crypto Security
This theft highlights key risks:
- Never Share Seeds: Even in photos, blur them out.
- Train Staff: Governments need crypto experts.
- Use Multi-Sig: Wallets with multiple approvals are safer.
- Third-Party Help: Let pros manage seized assets.
Blockchain is traceable, but thieves mix coins to hide tracks. Recovery is hard.
What Should Governments Do Next?
Experts call for change:
- Dedicated crypto teams in agencies.
- Regular audits and training.
- Secure storage like hardware wallets in vaults.
- Laws for virtual asset handling.
South Korea leads in crypto rules. This could push better standards.
Tips to Protect Your Own Crypto
Don’t let this scare you off crypto. Follow these steps:
| Do This | Avoid This |
|---|---|
| Use hardware wallets | Share seed phrases |
| Store seeds offline | Take photos of seeds |
| Use multi-sig for big amounts | Keep all eggs in one wallet |
| Check for updates | Click unknown links |
Public trust in government crypto handling is low now. But fixes can rebuild it.
Ongoing Investigation and Future Outlook
Police use blockchain analytics to follow the PRTG coins. They hope to catch the thief despite crypto’s privacy features.

The $480 million crypto theft shows crypto’s double edge: huge value, huge risks. Stay safe out there.
