Binance Hack: $6.3 Billion Stolen in Largest Crypto Heist Ever

The Binance hack that emptied the world’s largest cryptocurrency exchange of roughly six point three billion dollars in a single evening did not unfold slowly, like a leak that anyone might have spotted and plugged, because the money poured out of Binance’s hot wallets in a torrent that lasted only about twenty minutes, crossing ten different blockchains before most of the industry even understood what was happening, and by the time the outflow stopped, the theft had already doubled the scale of anything crypto had suffered before.

What makes the Binance hack so unsettling for ordinary holders is not only its size but the ordinariness of the doorway the attackers are believed to have used, since Binance’s own first account of the incident pointed to a laptop belonging to a DevOps engineer that had somehow been compromised, a machine that opened a path into a service container where unauthorised withdrawal requests could then be submitted as if they were legitimate, and although the exchange said on Friday that its investigators had since found additional points of breach, the picture that emerges is of a fortress entered through a side door rather than smashed through its front wall.

How the Binance Hack Unfolded in Twenty Minutes

Late on Thursday, October 29, the wallets began to drain, and blockchain trackers watched in something close to disbelief as the stolen pile grew, with analytics firm Arkham Intelligence recording that wallets believed to belong to the attackers held more than five point seven billion dollars at one point, including eighteen thousand two hundred and seventy bitcoin worth around one point four seven billion dollars, roughly nine hundred million dollars of ether, and vast quantities of the stablecoins tether and USD Coin that usually sit quietly at the heart of crypto trading.

The speed of the Binance hack is part of what separates it from every earlier theft, because the previous record, the roughly one point five billion dollars taken from the Bybit exchange in February 2025, now looks almost modest beside a haul more than four times larger, and TRM Labs calculated that about six point three six billion dollars left Binance wallets across ten blockchains, with most of it gone inside that single twenty-minute window.

Who Investigators Blame for the Binance Hack

Two of the most respected blockchain intelligence firms, TRM Labs and Chainalysis, have linked the Binance hack with high confidence to TraderTraitor, a North Korean hacking unit tied to the Lazarus Group, pointing to the sophistication and velocity of the operation as hallmarks of a crew that has spent years perfecting exactly this kind of raid, and the attribution carries an uncomfortable echo of the Bybit theft, which the FBI also blamed on Pyongyang, although North Korea routinely denies involvement in such attacks and Binance itself has so far named no culprit.

The market’s reaction to the Binance hack was swift and unforgiving, with bitcoin sliding about five percent in the early hours to a six-week low of seventy-six thousand three hundred and sixty-eight dollars, after trading near eighty thousand dollars before the news broke, while ether fell more than three percent to around two thousand one hundred and seventy-eight dollars, a reminder that even traders who never held a coin on Binance can feel a shock that begins inside one exchange’s walls.

Binance Freezes $3 Billion and Promises to Cover Losses

Binance moved quickly to reassure its users after the Binance hack, with co-chief executive Richard Teng posting that the bottom line was simple, that customers’ money was safe and that the company would cover every loss, while fellow co-chief executive Yi He made the same pledge in her own message, and the exchange said it had set aside more than six point three four billion dollars in company resources to restore customer balances, with five billion dollars already held in the exact token assets that were affected.

Partners across the industry froze around three billion dollars of the stolen funds, including two point three billion dollars in tether and USD Coin, a salvage effort that still leaves roughly three point three billion dollars unaccounted for, and Binance kept deposits open while pausing withdrawals as it rebuilt its withdrawal system, telling users it expected to reopen them within about forty-eight hours.

It is worth remembering that Binance held roughly one hundred and forty-four billion dollars of assets on its platform before the Binance hack, according to DefiLlama data, and that its emergency reserve created in 2018 holds about one billion dollars, which means this theft is more than six times the size of the safety net and the rest of the bill must come from company funds.

What the Binance Hack Means for Crypto Security

The wider context makes the Binance hack harder to dismiss as a one-off disaster, because DefiLlama has already recorded three hundred and twenty-two confirmed incidents in 2026 with losses above eight point seven billion dollars, and TRM Labs notes that this theft alone is more than double the two point nine billion dollars stolen in nearly one hundred and fifty attacks across all of last year.

Our own reading of the Binance hack is that it marks a turning point for how seriously exchanges, regulators and ordinary users treat the plumbing of crypto, because a theft of this size, executed in minutes and attributed to a state-linked crew, will inevitably sharpen calls for stronger withdrawal safeguards, slower settlement for large transfers, and coordinated industry responses, and the uncomfortable question now is not whether another exchange will be tested, but whether the lessons of this week will be applied before the next test arrives.
