Binance Lost $6.3 Billion in About 20 Minutes. The Attack Started With One Laptop
On 29 October 2026 attackers drained roughly $6.3 billion from Binance hot wallets in about 20 minutes, 4 times the size of the previous record. The way in was a compromised engineer’s laptop, and the clever part was a new Ethereum feature called EIP-7702 that let them turn a hot wallet into an automatic sweeper. I went through how it happened, how much got frozen, and why this did not break crypto the way it would have a few years ago.
