Definition ∞ Cross-chain phishing is a deceptive attack where malicious actors attempt to acquire sensitive information, such as private keys or seed phrases, by targeting users across different blockchain networks. Attackers create fraudulent messages or websites that imitate legitimate platforms on one chain, intending to compromise assets held on another. This tactic exploits user trust and the interconnectedness of the wider digital asset ecosystem.
Context ∞ Cross-chain phishing represents an evolving security threat as interoperability between blockchains increases. Users interacting with multiple networks must maintain heightened awareness against sophisticated social engineering schemes. Security advisories frequently warn about these attacks, stressing the importance of verifying URLs and transaction details before approving any actions.
