Crypto exchanges tighten security after $6.3 billion Binance hack

Rival platforms are adjusting cold storage, studying the breach, and calling for faster threat-intelligence sharing across the industry Binance lost approximately $6.3 billion from its hot wallets in roughly 20 minutes on October 29, 2026. The rest of the crypto industry is now quietly checking its own locks. Exchanges are reinforcing their defenses and pushing for faster sharing of threat information. The timing is uncomfortable. Crypto platforms are becoming more embedded in mainstream finance just as the biggest name in the business showed how quickly a vault can be emptied. The attack began at approximately 20:05 UTC on October 29.
