[Wu Blockchain News] Binance Details $6.34B Hack: Fake Job Interviews Used to Plant Malware, Internal...

Binance disclosed that its October 29 hack, which affected $6.34 billion in assets, began with fake job interviews that planted malware on an engineer's device in September. Attackers then exploited an internal AI tool to reach wallet engineers, used stolen credentials to compromise a wallet signing service, and abused Ethereum's EIP-7702 authorization mechanism; Binance said withdrawal suspensions alone could not stop the malicious on-chain authorizations, which required a separate revocation process. Approximately $2.85 billion of the affected assets has been frozen or intercepted, and Binance said 98% of affected token assets had been replenished as of October 31, with sufficient funds set aside to cover all losses. The incident matters because it exposed how social-engineering and AI-tool access can bypass wallet-signing controls at the largest exchange, and because EIP-7702 authorizations required a distinct revocation step beyond halting withdrawals. The investigation remains ongoing, with attention on recovery of the remaining frozen and intercepted funds and on whether Binance tightens access controls around internal AI tools and signing infrastructure.
