So... North Korea just casually stole $73M from Phemex.
And the way they did it? Chef's kiss. ๐จโ๐ณ
Let me tell you a story about hot wallets, 16 blockchains, and why your exchange might be next.

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.

4/ Key Lesson:
Even multisig cold wallets can be compromised through UI manipulation.
Verify EVERYTHING at the blockchain level.
Never trust the interface alone.

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

5/ Multisig Vulnerabilities:
โ ๏ธ Phishing attacks on signers

โ ๏ธ Compromised private keys
โ ๏ธ Insider threats
โ ๏ธ Insufficient signer verification
One compromised signer = protocol at risk.
