The Binance hack that drained an estimated $6.3 billion from the world’s largest crypto exchange may have started on a single employee’s computer. On October 30, 2026, Binance said its initial investigation points to a compromised laptop belonging to a DevOps engineer, which may have let an attacker reach a service container and submit unauthorized withdrawal transactions, Cointelegraph reported.
Why it matters
If the estimate holds, this is the largest exchange theft on record, roughly four times the $1.5 billion taken from Bybit in February 2025. Binance’s early findings also suggest that one breached work device may have been enough to move billions out of a major platform.
What we know about the Binance hack
Binance says it found no evidence that any wallet private key leaked. That detail matters. Read alongside the laptop finding, it suggests the weak point may have been the internal systems able to submit withdrawals rather than the keys themselves. According to Finance Magnates, the exchange put the estimated total impact at around $6.3 billion and promised a detailed technical post-mortem once the investigation is complete and the facts are verified.
Speed is what stands out. Ben-Natan of security firm Blockaid said at least $3.5 billion left Binance hot wallets on Ethereum, Arbitrum, Optimism and Avalanche in under an hour. Investigators also tracked 233.46 million XRP, worth nearly $296 million, leaving five Binance wallets before the Ethereum attack began, as cited by Bitbase.
Timeline of the withdrawal freeze
At about 00:30 GMT on Friday, Binance suspended all deposits and withdrawals while it ran security checks, froze funds and worked with law enforcement, Yahoo Finance reported. Later updates, as crypto.news noted, said deposits remained operational, while withdrawals stay paused as the exchange upgrades withdrawal systems and address controls. Binance expects withdrawals to resume within 48 hours. We have also covered crypto liquidations amid Binance hack fears.
Binance hack losses and frozen funds
Roughly $3 billion has been frozen on-chain with help from blockchain partners, FX News Group reported. Stablecoin issuers played a big part. Tether CEO Paolo Ardoino, Circle CEO Jeremy Allaire and Ripple’s Jack McDonald froze more than $2.3 billion in stablecoins, according to The Crypto Times.
Binance says it will cover all losses from its SAFU fund and company funds. Co-founder Yi He was quoted by The Week as saying: “Binance will cover all hacking losses.”
What is still unclear
Attribution so far comes from outside analytics firms. TRM Labs said it has “high confidence” the attack was orchestrated by TraderTraitor, citing “robust on and off-chain intelligence,” Yahoo Finance reported. Singapore-based Pangolin Intelligence also believes a North Korean hacking unit was behind it, CNN reported.
Several other questions remain open. It hasn’t been made public how the engineer’s laptop was compromised, how long the attacker had access, or how much of the remaining roughly $3.3 billion can still be recovered. Binance’s wording also stays cautious: the laptop “may” have allowed the access. The promised post-mortem should fill in those gaps.
How markets and analysts reacted
The news hit during early Asian trading. The Week reported Bitcoin fell 2.3% to $77,218 at that point. By 09:13 UTC, CoinGecko data showed broader 24-hour losses, with BNB, the token tied to the exchange, down the most of the assets below. Those moves reflect the whole 24-hour window, not only the hack.
| Asset | Price (Oct 30, 09:13 UTC) | 24h change | 24h low |
|---|---|---|---|
| Bitcoin (BTC) | $77,743 | -3.07% | $76,443 |
| Ethereum (ETH) | $2,222.96 | -4.30% | $2,178.62 |
| BNB | $703.54 | -6.49% | $682.36 |
| XRP | $1.26 | -2.67% | $1.20 |
| Solana (SOL) | $97.09 | -3.37% | $92.64 |
Sentiment is weak. The Crypto Fear & Greed Index read 30, or “Fear”, on October 30. For more on the price reaction, see our report on the Bitcoin price drop after the Binance hack and our coverage of Bitcoin long liquidations following the hack.
Changpeng Zhao, who co-founded Binance but stepped down as CEO, said he expects user funds to be safe. That’s a statement of expectation, not an audited figure.
What it means for investors
Binance’s pledge to cover losses is a company commitment, and how it plays out will depend on the final damage and recovery numbers. Holding assets on any centralized exchange carries custody risk: platforms can be hacked, freeze withdrawals without notice or face regulatory action. In a rare event like this one, access to funds can be blocked for days.
The attack vector is a reminder that the weak link can sit outside the core code, in the devices and access rights of staff. Scammers tend to exploit moments like this. Expect fake “refund” or “compensation” messages, and never share a seed phrase or login code with anyone claiming to represent an exchange. Volatility in BNB and the wider market may stay high until withdrawals resume and the post-mortem lands. None of this is investment advice.
Bottom line
Binance’s early findings point to a hijacked engineer’s laptop, and the exchange says it found no evidence of a private key leak. About $3 billion of the estimated $6.3 billion has been frozen so far. Whether withdrawals reopen within the expected 48 hours, and what the full post-mortem reveals, will show whether the exchange’s recovery plan holds up.
