Binance traces $6.34B hack to fake job interview and details attack timeline
Binance disclosed that a months‑long hack costing about $6.34 billion began when a recruiter on a legitimate job site approached an engineer in September, leading to a fake CEO interview that prompted the download of malicious code. The malware spread to wallet engineers, and on Oct 20 attackers used an internal AI tool to access two engineers. On Oct 29 they exploited a signing service via an EIP‑7702 delegation to empty a hot wallet. Binance halted the delegation at 8:10 p.m. ET, froze roughly $2.85 billion, and is rebuilding its wallet system. The report notes no cyber insurance and that the attack involved trusted personnel and tools rather than cryptographic breaks.
