in conclusion

Event characterization

This was a meticulously planned attack targeting high-value NFT holders, suspected of using phishing to obtain private keys and then rapidly liquidating their holdings. The attackers demonstrated a deep understanding of CryptoPunks market mechanisms and liquidity, choosing a pricing strategy slightly below the floor price to ensure quick transactions and transferring assets via OTC wallets.

• Opportunity cost : If calculated at the floor price of 29 ETH, an additional loss of 12 ETH would be incurred.
• Further losses : Punk #9901 is suspected of being further stolen (120 ETH), bringing the total loss to approximately 340 ETH (about $1.37 million).

Safety Notice

1. Wallet segregation : High-value NFTs should use hardware wallets or multi-signature schemes.
2. Phishing Prevention : Beware of phishing websites, malicious signature requests, and social engineering attacks.
3. Asset monitoring : Use wallet monitoring tools to promptly detect abnormal transactions.
4. Community verification : Verify contract addresses and transaction parameters through official channels before major transactions.
