A series of at least seven address poisoning attacks have targeted Ethereum, exploiting low gas fees to poison 300-500 wallet addresses per transaction at a cost of just $0.1 to $0.5. These attacks involve two main strategies: poisoning with real tokens like USDT or USDC, and using fake tokens. The latter can be effective due to some wallets' inadequate defenses against such attacks. The responsibility largely falls on wallet holders to ensure their security, as wallets with robust address poisoning detection and defense mechanisms are highly advantageous. Users are advised to utilize wallet address whitelisting features to protect against these attacks, emphasizing the importance of personal vigilance as the final line of defense in the cryptocurrency space.
