Haipo Yang, Founder of CoinEx, stated that the recent Binance security breach exposed at least three critical mistakes that were entirely avoidable, underscoring a failure of operational discipline rather than a lack of sophisticated technology. First, development and operations environments lacked strict isolation; production access should be restricted to dedicated hardware free of third-party software, separating daily communication and browsing onto independent devices.

Second, the operations stack lacked meaningful two-factor authentication (2FA), enabling full production compromise via a single leaked credential rather than enforcing hardware-bound MFA through tools like AWS Session Manager. Third, the MPC multi-signature setup existed in name only, as signers failed to conduct substantive independent verifications, causing the entire scheme to collapse upon a single node breach; Yang emphasized that multisig mechanisms are only effective when signers maintain mutual distrust and independently validate each raw transaction rather than blind-signing upstream requests.
