Security researcher Andrey Sergeenkov links recent Ethereum activity spike to cheaper address poisoning attacks enabled by Fusaka upgrade’s 60% fee reduction, causing $740,000 in user losses.
Security researcher Andrey Sergeenkov reported a surge in Ethereum transactions and active addresses tied to large-scale address poisoning attacks exploiting lower gas fees after December’s Fusaka upgrade. Fees dropped by over 60%, making dust attacks cheaper. More than 116,000 victims collectively lost over $740,000. The spike coincides with heightened spam activity, mirroring January’s 2.7 million new addresses and over 2.5 million daily transactions reported earlier.
