The world’s largest cryptocurrency exchange, Binance, confirmed on October 29, 2026, that it had been hit by a record $6.3 billion (£4.7bn) hack, described as the biggest heist in history. The exchange immediately pledged to cover all customer losses, freezing $3 billion of the affected assets and setting aside an additional $6 billion from its $167 billion balance sheet to shore up further losses.
$6.3 Billion Heist: North Korea Blamed
Analysts and researchers identified North Korea as the likely culprit behind the unprecedented attack. The Federal Bureau of Investigation (FBI) named the Democratic People’s Republic of Korea as responsible for the incident. TRM, a crypto analysis firm, attributed the attack with high confidence
to TraderTraitor, North Korea’s elite hacking unit, a conclusion shared by Elliptic and Chainalysis.
Engineers Infected with Tampered Installer
Binance detailed the multi-month infiltration used by the attackers in a November 3 disclosure. The campaign involved three engineers across several months. In June 2026, an engineer on Binance’s wallet development and operations team downloaded a tampered Homebrew installer while trying to install a popular AI coding tool. The company’s security team detected the anomaly. They replaced the affected device and changed related credentials. But the attack had already exposed the engineer’s role and colleagues working on the wallet infrastructure.

In September, the attackers posed as recruiters. They ran a series of fake job interviews with another engineer. This led to a coding exercise that contained hidden malware designed to evade security. The attackers spent months building their way in. On October 20, they used the compromised computer and an internal AI tool to access other employees. This included one with a container deployment permission token.
Replenishing Stolen Customer Assets
Following the attack, Binance suspended withdrawals and began an immediate recovery effort. As of November 1, the exchange had replenished approximately 98% of the $6.34 billion in affected assets, according to an update from Binance. The company said it had set aside more than 100 per cent of the funds required to cover the stolen assets from its own resources. This ensured customers would not bear the financial impact.

By November 4, Binance announced it had replenished approximately 98 per cent of the impacted token assets, up from the 95 per cent disclosed in a previous update. The remaining two per cent consists of less liquid tokens that require more time to acquire in the required quantities. Premium Times Nigeria reported that Binance had already frozen or intercepted about $2.85 billion in assets through a coordinated effort with partners like Tether, Circle, and Ripple.
The hack sent ripples through the crypto markets. Within hours of the news breaking in early Asian trading on Friday, The Guardian reported that bitcoin had fallen 5% from its level before the hack broke. It dropped to $77,380, its lowest level in six weeks. Binance co-founder CZ Zhao posted to X to say user funds are safe. But he added the incident appears to be a hack.

Moving Stolen Funds Through Wallets
The stolen funds are being moved through complex and automated laundering operations. According to blockchain analytics firm Elliptic, in the first three and a half days after the hack, the attackers used about 12,000 wallets across 11 blockchains. They made a new wallet roughly every 25 seconds. As of November 5, about $3.35 billion remains in addresses linked to the theft, mostly as ETH and BTC. Elliptic estimates that only a negligible amount has likely been cashed out.
The FBI’s investigation prompted a response from the crypto industry and regulators. The bureau published 628 crypto addresses linked to the theft and called on crypto services companies to block transactions with them. The alert did not name banks. According to American Banker, little of the stolen money appears to have come near a traditional bank.

Rebuilding Wallet System After Breach
In the wake of the breach, Binance has undertaken a comprehensive security overhaul. The exchange has rebuilt the affected wallet system in a new environment. It rebuilt its internal AI tool and access controls. The exchange replaced compromised devices and decommissioned credentials and tokens associated with the affected employees. Premium Times Nigeria reported that Binance security had detected and prevented 57 suspected North Korea-linked cyber threat cases throughout 2026.
Binance co-CEO Richard Teng told CNBC that the company is getting an independent expert to review its security measures. He said it will continue to strengthen its defenses as the investigation continues. The exchange has also pledged to publish a comprehensive post-incident report after completing its investigation. This will promise further details about the breach and the measures taken to prevent a recurrence.
