Crypto exchanges call for quick moves to bolster defenses after Binance heist

Crypto exchanges are taking quick action to bolster their defenses and urging greater industry-wide information-sharing after a record $6.3 billion hack of Binance exposed their vulnerability just as they become more embedded in mainstream finance.

Coinbase said it made adjustments to its systems that store cryptocurrency keys offline “solely out of an abundance of caution,” while Kraken said it was monitoring industry incidents for lessons it could apply to its defenses.
