Ethereum study flags 65,340 risky addresses tied to $574.8M

A USENIX Security ’26 study highlights major security risks on Ethereum and BNB Smart Chain, identifying 65,340 high-risk address instances tied to estimated native-token losses of 126,982.94 ETH and 17,726.7 BNB, valued at more than $574.8 million using reference prices. The research breaks misuse into contract-address confusion and exposed-private-key EOAs, with most EOA losses linked to GitHub-exposed keys. It also describes two newer attack vectors: deterministic contract-address exploitation and EIP-7702 delegation abuse, together accounting for roughly $15.7 million in losses. The findings reinforce ongoing concerns about wallet security, cross-chain address mistakes, and malicious delegation mechanisms, adding pressure for stronger warnings, secret management, and clearer network labeling across crypto infrastructure.
