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

Crypto exchanges are taking swift action to tighten security and encourage greater industry-wide information sharing following a massive $6.3 billion hack of Binance, a major crypto exchange. Coinbase made changes to its systems to store cryptocurrency keys offline "out of an abundance of caution," while Kraken stated it was monitoring industry incidents for lessons to improve its defenses.

However, the industry needs to act urgently as U.S. President Donald Trump's regulators push for deeper integration of digital assets into the financial system, raising the stakes for an industry with a history of significant hacks. Chris Perkins, head of crypto at Franklin Templeton, emphasized the need for immediate action to bolster security.

Binance halted withdrawals after the attack, which analysts suspected was orchestrated by North Korea, and pledged to use company funds to cover the losses. The company discovered additional breaches, and the hack complicated investigative efforts. Rival exchanges swiftly fortified their systems, reassuring customers that their tokens remained secure.

Despite the largest cryptocurrency heist ever recorded, executives expressed confidence that Binance could cover the losses without broader financial repercussions. Bitcoin and ether, the second-largest cryptocurrency, experienced sharp declines on Thursday but recovered some ground on Friday. Analysts noted that social engineering, a tactic where hackers trick victims into disclosing sensitive information or gaining system access, may have played a role in the Binance hack.

Companies are implementing more employee training to combat such attacks. Tether and Circle froze billions linked to Binance, but stablecoins, which lack a central authority, cannot be frozen. Chainalysis reported that the hackers employed advanced laundering techniques, a first for them. Some crypto exchange executives now advocate for a coordinated hack detection system that enables immediate information sharing, rapid response, and temporary freezing of suspected stolen funds.
