ShareThe Binance Hack: How to Protect Your Crypto When an Exchange Is Breached
You wake up to news that your crypto exchange has been hacked. You open the app and your balance is still there, but withdrawals are paused. Then a text arrives claiming to be from support, telling you to move your funds to a “safe wallet.” Which information should you trust, and can you still get your crypto out?
The October 2026 Binance hack, which affected approximately $6.34 billion in crypto assets, made those questions real for exchange users. Here’s what happened, what you can do when withdrawals are open or paused, and how to move crypto to a wallet you control.
What Happened in the $6.34 Billion Binance Hack?
The attack began at approximately 20:05 UTC on October 29, 2026, shortly after midnight on October 30 in Georgia. According to Binance’s preliminary findings, attackers used compromised employee computers and stolen internal credentials to reach a service that authorized transactions from the exchange’s hot wallets. These are internet-connected wallets the exchange uses to move crypto. Within four minutes, five Binance wallets sent a combined 233.46 million XRP to an address controlled by the attacker. Unauthorized transfers also affected other assets, including Bitcoin and Solana.
Binance temporarily paused withdrawals and said it would cover the losses through its Secure Asset Fund for Users (SAFU) and company funds. Withdrawals began reopening in phases on November 1, with Bitcoin, Ether, and some stablecoins among the first assets available. In its November 3 report, Binance said approximately $2.85 billion in affected assets had been frozen or intercepted. That figure describes assets the response teams were able to block or intercept. Binance’s commitment to cover losses was a separate part of its response.
An exchange balance shows what the platform credits to your account. To send that crypto to an external wallet, the exchange still needs to process and authorize a withdrawal. That’s why your balance can be visible while transfers are paused. A platform-wide pause calls for checking the exchange’s status. An unfamiliar withdrawal or login on your own account calls for contacting official support and securing your account promptly.
What Should You Do During a Crypto Exchange Hack?
First, Verify the News and Check Your Account
Open the exchange through its official app or a bookmark and look for an incident notice. Check your recent logins, trades, and withdrawals. If something looks unfamiliar, contact support through the app or official website. Use the account lock feature if the exchange offers one, and secure your linked email from a trusted device.
Be especially careful with messages that seem to know what’s happening. A text might say, “Your account was affected. Transfer your crypto to this secure wallet within 30 minutes.” Treat the message as a reason to check the exchange directly. Keep your passwords, verification codes, and wallet recovery phrase private, and use a receiving address generated by your own wallet.
If Withdrawals Are Open, Check Before You Transfer
Check withdrawal availability for both the asset and the network you plan to use. An exchange can reopen Bitcoin withdrawals while other assets or networks are still paused. If you decide to transfer funds, open your receiving wallet, verify the address and network, and send a small test amount where the fees and withdrawal minimum make it practical. Wait until it arrives before sending more. Meanwhile, read more about Cryptal’s withdrawal guide
If Withdrawals Are Paused, Follow Official Updates
If the exchange has paused withdrawals for your asset and network, you’ll have to wait for it to reopen that route before you can initiate an on-chain transfer. Save your account records, including any pending withdrawal references, timestamps, and transaction IDs if available. If you spot unauthorized activity, share those details through official support. Avoid anyone asking for an upfront fee to unlock withdrawals or recover funds.
How to Move Crypto From an Exchange to Your Own Wallet
Understand Who Controls the Keys
A private key is what lets someone authorize a transaction from a crypto wallet. The main difference between an exchange wallet and a self-custody wallet is who manages those keys.
| Wallet type | Who controls the keys? | What to consider |
|---|---|---|
| Exchange wallet | The exchange | Convenient for trading. Withdrawals depend on the exchange’s systems and availability. |
| Self-custody software wallet | You | Accessible on a phone or computer. You’re responsible for the device and wallet backup. |
| Hardware wallet | You | A dedicated device can keep private keys offline. You still need a secure backup to restore access if the device is lost or damaged. |
Walk Through a First Bitcoin Withdrawal
Suppose you want to move BTC from an exchange to your own Bitcoin Wallet. Here’s what the transfer looks like.
- Set up your Bitcoin Wallet and back it up. Follow the wallet’s setup instructions and secure its recovery backup before transferring funds.
- Generate a receiving address. Open your Bitcoin Wallet, select Receive, and copy the Bitcoin address it shows.
- Choose BTC and the Bitcoin network on the exchange. Paste the receiving address into the withdrawal form. Compare the pasted address with the one in your wallet, and verify that both sides use the Bitcoin network.
- Review the fee and withdrawal minimum. Send a small test amount if practical, and wait for the wallet to show it as received.
- Send the remaining amount you intend to move. Check the address and network again before approving the withdrawal.
The exact menu labels vary by exchange. If you’re withdrawing from Cryptal, the support guide explains where to find the withdrawal form and which details to review.
Protect the Recovery Phrase
Many self-custody wallets give you a recovery phrase, a series of words that can restore access to the wallet. Anyone who gets those words can potentially take control of the funds. Keep your backup offline in a secure place. Avoid storing it in screenshots, email, or chat, and never share it with someone claiming to be support. If you need to restore a wallet, use the official recovery process for your wallet software or device.
How to Prepare Before the Next Exchange Breach
- Decide how much crypto you need on the exchange. Consider what you use for trading or conversion and what you plan to hold longer. That gives you time to decide which assets you’re comfortable managing in self-custody.
- Set up and test your wallet in advance. Practise receiving a small amount so you know where to find the address, how to check the network, and what a completed transfer looks like.
- Secure the accounts you use. Set up a passkey where available, protect your linked email with strong two-factor authentication, and use a withdrawal address allowlist if your exchange offers one. These settings help protect your account from unauthorized access and withdrawals.
Frequently Asked Questions
Can I Move My Crypto if the Exchange Has Paused Withdrawals?
You’ll need to wait until the exchange reopens withdrawals for your chosen asset and network. Availability can vary by asset and network, so check the official withdrawal status before initiating a transfer.
Can an Exchange Hack Affect Crypto Already Held in My Own Wallet?
If the transfer has already confirmed and you control the receiving wallet’s keys, the exchange has no authority to move those funds. The wallet’s security then depends on how you protect your keys and recovery backup and what transactions you approve.
What Happens if I Send Crypto to the Wrong Address or Network?
A confirmed transfer generally can’t be reversed. With a wrong-network transfer, recovery depends on the networks involved and who controls the receiving address. Save the transaction ID and contact the receiving platform through official support if its address was involved.
What Happens if I Lose My Hardware Wallet?
You can typically restore access on a compatible wallet using your recovery backup. If you lose both the device and the backup and have no other way to access the keys, the funds may be permanently inaccessible.
Summary
If you hear that a crypto exchange has been hacked, verify the alert through the exchange, check your account activity, and confirm whether withdrawals are open for your asset and network. If you decide to move funds, use a wallet you control and confirm a small test transfer where practical. Setting up that wallet and securing its backup ahead of time gives you room to make each check without the pressure of a security incident.
