Etherscan: Ethereum Fusaka upgrade leads to a surge in poisoning attacks due to reduced transaction costs Odaily Planet Daily News: According to Etherscan research, there has been a significant increase in address poisoning attacks on the Ethereum network recently. Attackers insert wallet addresses with highly similar characters before and after the real address into user transaction records by sending counterfeit address transactions, thereby inducing users to mistakenly copy the wrong address during subsequent transfers. Research shows that between July 2022 and June 2024, there were approximately 17 million address poisoning attempts on the Ethereum network, targeting around 1.3 million user addresses, with confirmed losses of at least $79.3 million. Attacks are usually carried out through methods such as zero amount transfers, fake token transfers, or dust transfers, and are automatically initiated within minutes after the user completes a real transaction. Although the success rate of a single attack is only about 0.01% (about 1/10000), attackers rely on a "quantity advantage" to gain profits by sending large-scale poisoning transactions through automated systems. The study also found that different attack groups often compete for the same target address, attempting to write counterfeit addresses into transaction history first. In addition, the Fusaka upgrade activated on December 3, 2025 reduces Ethereum transaction costs, allowing attackers to send large amounts of poisoning transactions at a lower cost. Within 90 days after the upgrade, the daily average transaction volume of Ethereum increased by about 30% compared to the previous 90 days, and the number of new addresses added per day also increased by about 78%. At the same time, there was a significant increase in small-scale dust transfer activities. Etherscan reminds users to carefully check the target address before transferring funds. Real addresses can be distinguished by address labels, ENS domain names, wallet address books, or address highlighting functions to reduce the risk of erroneous transfers. Due to the irreversibility of blockchain transactions, once funds are sent to the wrong address, they are often difficult to recover.
