Inside the largest crypto hack on record: How attackers breached Binance for $6.3 billion
深入史上最大加密货币黑客事件：攻击者如何从币安盗走63亿美元
Binance's $6.3 billion breach traced to hot-wallet signing controls, so readers should weigh whether exchange key management or investigator attribution matters more for their own custody decisions.
Judgment
Custody and exchange security leads must now decide whether to re-verify hot-wallet signing controls — signer isolation, approval thresholds, key custody — before independent attribution confirms the North Korea link, accepting slower withdrawals as the price of removing a single signing point of failure.
Basis
The Block, citing investigators, ties the $6.3 billion Binance breach — stated elsewhere in the same source as $6B — to North Korea, and places the mechanism in hot-wallet signing infrastructure: that signing layer was compromised, and funds then moved. The chain is attribution plus a specific technical locus, not a general phishing story, which is why the reader's own key-management choices sit on the same facts as the investigator's attribution claim. The excerpt carries only the loss figure and the mechanism; it gives no timeline, no share of reserves, no split between traced and unrecovered funds, and no detail on which signer or approval policy failed.
Unclear The source does not say which signing component was breached, how keys or approval quorums were obtained, or what evidence substantiates the North Korea attribution.
