How did they drain $6.3 billion?
The state-sponsored US designated APT (Advanced Persistent Threat) group executed the heist through an intricate, rapid and precise breach. The attack focused on the Binance infrastructure that specializes in transaction signing. It was a persistent multifold attack on ten different blockchain networks for nearly twenty minutes.

-
The Execution Part of the Operation
The attackers triggered the automated sweep calls as they were able to leverage EIP-7702 features, particularly when it comes to Ethereum. The sweep calls led to temporary execution of smart contract code for the standard accounts, while dispatching the signed batch transactions to Binance hot wallets on other chains.
-
Evading Security Checks
The hackers issued unauthorized withdrawal instructions which standard approval controls bypassed along with the risk flags. For a brief period of time, automated sweeps concurrently happened during the breach, following which the assets were transferred directly into compromised hot wallets. The attackers were quick to siphon off those assets from there.
