Etherscan: Ethereum Address Poisoning Attack Scale Surges After Fusaka Upgrade

Techub News reports that poisoning attacks on addresses on Ethereum are intensifying, especially after the Fusaka upgrade lowered transaction costs, leading to a significant increase in high-frequency attack activities. A study covering July 2022 to June 2024 shows approximately 17 million poisoning attempts on Ethereum, affecting about 1.3 million users, with confirmed losses of at least $79.3 million. The Fusaka upgrade activated on December 3, 2025, not only reduced transaction fees but also greatly lowered the cost of attacks. Within 90 days after the upgrade, the volume of scattered USDT transfers (less than $0.01) surged from 4.2 million to 29.9 million, a 612% increase; USDC scattered transfers increased from 2.6 million to 14.9 million, a 473% increase. ETH scattered transfers (less than 0.00001 ETH) grew from 104.5 million to 169.7 million, a 62% increase. Etherscan states that the success rate of a single poisoning attack is about 0.01%, but attackers can still achieve significant profits through large-scale batch sending.

Address poisoning attacks involve sending small counterfeit address transfers to target wallets, embedding fake addresses into users’ transaction histories, and tricking users into copying the wrong address during their next transfer.
