Binance Confirms Security Breach Tied to Wallet-Signing Service

Binance confirmed a significant security breach involving its wallet-signing service, bringing the exchange’s transaction-authorization controls into focus. The account @SolanaFloor said an engineer inadvertently downloaded a malicious file on a work computer, helping attackers reach sensitive systems. The claim links the alleged intrusion to an employee’s device. A wallet-signing service is used to authorize digital-asset transactions. The breach therefore centers on part of exchange infrastructure that can affect how transactions are approved and how users assess platform security. Binance operates a large cryptocurrency exchange that offers trading in multiple digital assets.
