January 2025. Phemex wakes up to a nightmare.

$73 MILLION gone.

Not from one wallet. Not from one chain.

From hot wallets across 16 different blockchains.

Ethereum. Solana. Bitcoin. All of them.

This wasn't a hack. This was a heist.

So... North Korea just casually stole $73M from Phemex.

And the way they did it? Chef's kiss. 👨‍🍳

Let me tell you a story about hot wallets, 16 blockchains, and why your exchange might be next.

4/ Key Lesson:

Never trust the interface alone.

@StoryProtocol 6/ Lessons for protocols:

✅ Use hardware wallets for ALL signers
✅ Implement time-locks on upgrades (24-48hr minimum)
✅ Require multiple independent verifications
✅ Monitor governance actions 24/7
✅ Use cold storage for critical operations

@StoryProtocol 5/ Multisig Vulnerabilities:

⚠️ Phishing attacks on signers
⚠️ Social engineering
⚠️ Compromised private keys
⚠️ Insider threats
⚠️ Insufficient signer verification

One compromised signer = protocol at risk.
