A delegation attack exploits vulnerabilities in how permissions are granted or managed within a system, particularly in delegated proof-of-stake blockchains or smart contract environments. Attackers seek to gain unauthorized control over delegated voting power or asset management rights. This can involve tricking users into delegating to malicious actors or exploiting flaws in the delegation contract itself. Such attacks can compromise network security or user funds.
Context
News reports on delegation attacks highlight the importance of secure delegation practices and robust smart contract auditing in decentralized governance and staking protocols. These incidents underscore the need for users to exercise caution when delegating their assets or voting power. Developers continuously work on improving delegation security mechanisms and educating participants about potential threats.
EIP-7702-style delegation is weaponized to bypass traditional `approve` checks, granting malicious contracts persistent, batch execution authority over user assets.
