On October 29, 2026, the crypto industry saw its biggest theft ever. Binance, the world's largest exchange, said hackers stole about $6.3 billion, far beyond the previous record. Here is what we know, what it means for the market, and what you can do to protect your own assets.
What happened
Blockchain analysis firms TRM Labs and Chainalysis say most of the theft unfolded over about 20 minutes, with the attacker moving roughly $6.36 billion out of Binance wallets across 10 blockchains. That dwarfs the $1.5 billion stolen from Bybit in February 2025.
Binance suspended deposits and withdrawals and said it would cover all losses, telling Al Jazeera that user funds were "safe." It also warned that the $6.3 billion figure may continue to rise as it traces more assets.
How the attack worked
Binance's first finding was that the breach went through an engineer's laptop, which let the attacker reach a service container and submit unauthorized withdrawal transactions. Co-CEO Richard Teng said it was not a "one-click" action but a complex process.
The picture has since widened. On Friday, Binance said further investigation had uncovered additional points of breach, though it still found no evidence that any wallet private key had leaked. Mark Karpeles, former head of the collapsed Mt Gox exchange, told Reuters he believes the attackers probably accessed keys for at least two Binance wallets. That disagreement is unresolved, so treat the technical details as preliminary.
The lesson is already clear: big breaches often start with people and devices, not with broken cryptography.
Who is blamed
TRM said it assessed "with high confidence" that the attack was carried out by TraderTraitor, a North Korean unit linked to the Lazarus Group. Chainalysis reached the same conclusion, and the FBI blamed the Bybit hack on the same unit. Pangolin Intelligence, a Singapore-based tracking firm, also believes a North Korean unit was responsible.
Binance is more cautious. Teng said the company's investigation has not attributed responsibility to any individual. North Korea has previously denied hacking allegations. This remains attribution by analysts, not an official finding.
Why it matters beyond crypto
North Korea's crypto theft has become a source of foreign currency that experts say helps prop up its economy and fund its sanctioned nuclear programme. TRM's Ari Redbord called it a global security issue, not just a crypto theft.
The race to freeze the money
Binance said about $3 billion has been frozen, including more than $2.3 billion by stablecoin issuers Tether and Circle, but it has not said what happened to the remaining $3.3 billion. The reason is that freezing works only for tokens whose issuer or governing body can block specific addresses. Stablecoins can be frozen, while many other assets cannot.
One analyst warned that the "cat and mouse game has barely begun," with North Korea likely to use money laundering networks to cash out. Funds not frozen early are rarely recovered.
Can Binance cover it?
The stolen amount is more than six times Binance's SAFU emergency fund, which was set up in 2018 and held in Bitcoin. Sources differ on its size: 21shares puts it at 15,000 BTC, about $1.18 billion. Either way, Binance has said company funds will cover the rest. Its proof of reserves as of October 1 showed net user balances of $134 billion against about $136 billion on-chain, a surplus near $2 billion. The company has said it will cover everyone, but the numbers show how much depends on its balance sheet.
Market reaction
Bitcoin hit a six-week low of $76,368 and Ether fell to a two-month low, while Coinbase shares fell 4.8%. Bitcoin's fall of just over 2% over 24 hours was far smaller than its 26% drawdown after FTX. The market treated this as a failure at one company, not a failure of Bitcoin. Analysts said crypto was already under pressure from higher US interest rates and weaker ETF demand.
DeFi saw only brief spillover. The attacker deposited 60 million stolen USDT into Aave and borrowed about $44.6 million in WETH within about three minutes. Aave froze its markets as a precaution and reported no bad debt.
The bigger lesson: centralized exchanges are giant targets
Sean Foley of Macquarie University said assets at a centralized exchange are only as safe as the exchange itself, and the larger its holdings, the bigger the target. Insurance won't save you either: most crime and cyber policies don't cover stolen cryptocurrency.
This is a pattern, not a one-off. TRM's 2026 report counted $2.87 billion stolen in nearly 150 attacks in 2025.
How to protect your crypto
You can't control an exchange's security, but you can control your exposure.
1. Don't keep everything on one platform. Keep only trading funds on exchanges. Move long-term holdings to a hardware wallet that you control.
2. Plan for a pause. Even when users are covered, withdrawals can be frozen for days. Keep an emergency reserve you can reach anytime.
3. Use phishing-resistant 2FA. Use a hardware security key or passkey instead of SMS codes, and turn on anti-phishing codes and withdrawal address whitelisting.
4. Treat your own device like a vault door. This attack began with an engineer's laptop. Keep your devices updated, avoid pirated software and unknown extensions, and don't do crypto on a machine you use for everything.
5. Split your funds. Use separate wallets for daily use, DeFi and long-term storage, so one failure can't take everything.
6. Clean up permissions. Delete unused API keys and revoke old smart contract approvals.
7. Watch for scams. After a big hack, fake "refund" and "compensation" links spread fast. Never share your seed phrase, and only trust official channels.
8. Back up offline. Store your seed phrase on paper or metal, never in screenshots, notes apps or cloud storage.
9. Don't panic-sell. The market's quick recovery shows that panic selling usually locks in losses.
What to watch next
Withdrawals. Binance said it was on track to resume withdrawals within 45 hours of Friday's update.
Recovery. Whether the remaining $3.3 billion is traced or laundered.
Cause. Whether the investigation confirms stolen keys or a different path.
Official attribution. Whether governments formally name North Korea.
Bottom line
No security setup is perfect, and the biggest names are not immune. The best defense is to make sure no single failure, whether yours or an exchange's, can wipe you out.
