Binance hack, three operational controls pointed out by Yang Haipo

Binance disclosed that its October 29 security incident affected roughly $6.34 billion in crypto assets, with about $2.85 billion frozen or otherwise restricted as of its initial investigation report published November 3. Haipo Yang, founder and CEO of CoinEx and ViaBTC, attributed the breach to operational discipline failures rather than sophisticated technology, citing three control gaps: separation of development and production environments, two-factor authentication for operational privileges, and independent verification by transaction signers. His proposals target the devices and permissions that touch production systems and the procedures for approving transactions. The scale of exposed funds makes the incident a test of how exchanges segment access and enforce approval checks. What to watch next is whether Binance and peers adopt stricter environment isolation and dual-approval signing, and how much of the remaining affected balance is recovered.
