Binance Hack Explained: What Happened, Is Your Money Safe and What to Do Now

On Thursday, October 29, 2026, Binance, the world's largest crypto exchange, was hit by what looks like the biggest crypto hack in history. Binance estimates the total impact at about $6.3 billion, roughly four times the $1.5 billion Bybit hack of February 2025, which held the record until now.

If you have money on Binance, you probably have three questions: What happened? Is my money safe? What should I do right now? This guide answers all three in plain English. We'll keep it updated as Binance publishes more.

Short answer: Binance says user funds are safe and that it will cover all losses from its emergency fund (SAFU) and its own money. Deposits and withdrawals are paused while it investigates. There is nothing you need to do in your Binance account right now, but this is exactly when scammers strike, so read the safety section below.

What Happened, in Simple Terms

Think of an exchange like a bank with two kinds of safes:

• A cold wallet is the vault in the basement. It's offline, hard to open, and holds most of the money.
• A hot wallet is the cash drawer at the counter. It's online so withdrawals can be paid out quickly, which also makes it the most exposed.

On Thursday afternoon (US time), an attacker took control of some of Binance's hot wallets and emptied them in minutes. Here's the timeline, based on Binance's statements and on-chain data reported by CoinDesk, Bitcoin.com and blockchain security firms (times are US Eastern):

• About 4:20 p.m.: A special transaction is sent from a Binance hot wallet labelled "Binance 14". It hands control of the wallet over to code written by the attacker.
• About 4:24 p.m.: Funds start pouring out. A single transaction moved about 167,000 ETH and 1.6 billion USDT. A second Binance wallet sent another 28,000 ETH about 15 minutes later.
• Within about 40 minutes: One attacker address had collected around $3.5 billion in crypto. Bitcoin and Tron wallets also saw large outflows.
• Evening: Binance pauses withdrawals, then deposits too. Co-CEO Yi He says: "User funds are safe" and "Binance will cover all hacking losses."
• Late evening: Binance publishes its first findings and puts the total impact at about $6.3 billion, with about $3 billion already frozen.

How Did the Hackers Get In?

Binance's first investigation points to one employee's laptop. In its words, the incident "may involve a compromised DevOps engineer's laptop", which let the attacker reach an internal system and "submit unauthorized withdrawal transactions."

In everyday terms: the attacker didn't break the blockchain or "crack" Bitcoin. They got into a computer belonging to someone with access to Binance's internal tools, and used that access to send the money out as if it were a normal withdrawal.

Binance also says: "We have found no evidence of any wallet private key leak." Private keys are the master passwords that control crypto wallets. If they had leaked, every wallet using them would be at risk.

Security researchers think the attacker used a newer Ethereum feature called EIP-7702. It lets a normal wallet temporarily run a piece of code. The attacker appears to have used it to point the hot wallet at a "sweep" program that emptied it in a single transaction. This is still an analysts' reconstruction; Binance has promised a full technical report once the investigation is finished.

Who did it? Nobody has officially said. Blockchain investigator ZachXBT and researchers at TRM Labs say it looks like the work of North Korea's Lazarus Group, the same group the FBI blamed for the Bybit hack. Binance, governments and law enforcement have not confirmed this yet.

How Much Was Stolen, and How Much Is Frozen?

You'll see many different numbers this week. Here's why:

• About $6.3 billion: Binance's own estimate of the total impact.
• About $5.3–5.9 billion: estimates from on-chain analytics firms such as Glassnode and Chainalysis, based on prices at the time.
• About $3 billion frozen: Binance says partners have frozen roughly this much so far.

The freezes are possible because some coins are issued by companies that can lock them:

• Tether froze about 1.57 billion USDT.
• Circle froze about 800 million USDC.
• Ripple reportedly froze about $200 million, and World Liberty Financial about $27 million of USD1.
• The Arbitrum network's security council froze about 74.5 million tokens sitting in a hacker wallet.

Important: frozen is not the same as recovered. Frozen coins can't be moved by the hacker, but getting them back to Binance takes legal steps and time. Coins like ETH and BTC can't be frozen by anyone, so whatever the attacker moved in those coins is much harder to get back.

Is Your Money on Binance Safe?

Here's what Binance has committed to publicly:

1. It will cover all losses. Binance says it will pay from SAFU (its emergency insurance fund, about $1 billion held in Bitcoin) plus company funds. Users should not lose their balances.
2. Your account balance stays the same. The stolen coins came from Binance's own hot wallets, not from individual user accounts.
3. It will publish an updated proof of reserves (a public list of the wallets and assets that back customer balances) and a full post-mortem.

There is a precedent. In 2019 hackers stole 7,000 BTC from Binance; the exchange covered the loss from SAFU and customers didn't lose money. Bybit did the same after its $1.5 billion hack in 2025 and kept processing withdrawals.

The honest caveat: today, "your money is safe" rests on Binance's own balance sheet and promise. CoinDesk estimates the stolen ETH alone was about 5.6% of Binance's ETH reserves, so its ETH backing dropped from 100% to roughly 94% until it tops it back up. The next proof-of-reserves snapshot, due around November 1, should show whether the gap has been filled. That's the number to watch.

Can I Withdraw My Crypto?

Not right now. As of October 30, deposits and withdrawals are paused. Binance says they will resume "as soon as the security issue is fully resolved" and hasn't given a date. After the 2019 hack, withdrawals came back in about a week, but every incident is different.

What this means for you:

• Don't send new crypto to Binance until deposits officially reopen. Depending on the network, a transfer sent now could be delayed.
• When withdrawals reopen, expect queues and slower processing for a while.

What Happened to Prices?

The news hit the whole market on Thursday evening:

• Bitcoin fell about 5%, to under $78,000.
• Ethereum fell almost 6%, to about $2,230.
• BNB, Binance's own coin, fell about 8–10%.
• XRP and Solana dropped around 7%.

Some lending platforms, such as Aave, temporarily paused certain markets as a precaution, even though their own systems weren't hacked. Crypto was already under pressure from the macro backdrop this month (see our post on why crypto is down in October 2026), so the hack hit an already nervous market.

What Happens Next?

Here's what to expect over the coming days and weeks:

1. The investigation and post-mortem. Binance will explain exactly how the attacker got in and what it changed. This is the key document for trust.
2. Proof of reserves (around November 1). It should show whether Binance has replaced the missing assets.
3. Withdrawals reopening, probably network by network.
4. Chasing the money. Investigators and law enforcement will follow the stolen funds. Expect more freezes, but also attempts to launder the rest through mixers and other chains.
5. Rules and industry changes. Expect regulators to ask tougher questions about how big exchanges protect hot wallets, and more exchanges to add extra approval steps and time delays on large withdrawals.

What Should You Do Right Now?

Do:

• Stay calm. Panic and urgency are the scammers' best friends.
• Check news only from official sources. That means the Binance app, the Binance announcements page, and verified accounts such as @binance on X.
• Turn on strong security on every exchange account: an authenticator app or passkey for 2FA (not SMS if you can avoid it), a withdrawal address whitelist, and Binance's anti-phishing code, which adds a secret word to every real email Binance sends you.
• Take screenshots of your balances and open orders, just for your own records.

Don't:

• Don't click "refund", "compensation" or "claim your funds" links. Binance does not need you to fill in a form to get covered. Any message asking you to do this is a scam.
• Don't give out your password, 2FA codes or seed phrase. No real support agent will ever ask for them, by phone, email, Telegram or anywhere else.
• Don't trust "Binance support" calls. Binance has warned before about scammers who fake its phone number to sound official.
• Don't move your money to a "safe wallet" someone sends you. That is the most common scam after every hack.
• Don't make big trading decisions in a panic. If you trade, use small position sizes and a stop-loss. Volatility is high right now.

The Bigger Lesson: Not Your Keys, Not Your Coins

This hack is a reminder of one of crypto's oldest rules. When your coins sit on an exchange, the exchange holds the keys, and you rely on its security and its promise to pay you back.

That doesn't mean exchanges are useless. They're the easiest way to buy, sell and trade, and the biggest ones have strong safety nets. But for long-term savings you don't plan to trade, many people move coins to a self-custody wallet, ideally a hardware wallet, where only you hold the keys. If you do, write down your recovery phrase on paper, store it somewhere safe, and never type it into a website or share it with anyone.

Frequently Asked Questions

Was Binance really hacked?

Yes. Binance has confirmed a security incident in which an attacker sent unauthorized withdrawals from its hot wallets. Binance estimates the impact at about $6.3 billion, which would make it the largest crypto hack ever.

Will I lose my money?

Binance says no: it has promised to cover all losses with its SAFU fund and company funds, and says user funds are safe. The stolen coins came from Binance's own hot wallets, not from individual accounts. The next proof-of-reserves report, around November 1, will show whether the shortfall has been replaced.

Can I withdraw my crypto from Binance right now?

No. Deposits and withdrawals are temporarily paused while Binance runs security checks. Binance says they will resume once the security issue is resolved; it hasn't given a date yet.

Do I need to do anything in my Binance account?

No action is required to be covered. Turning on strong 2FA, a withdrawal whitelist and the anti-phishing code is a good idea anyway. Be very careful with any message telling you to "verify", "claim" or "move" your funds: those are scams.

What is SAFU?

SAFU stands for "Secure Asset Fund for Users." It's an emergency fund Binance created in 2018 to protect users in situations like this. It's currently worth about $1 billion and is held in Bitcoin. Binance says it will also use company funds on top of SAFU.

Who hacked Binance?

It's not officially known. Independent investigators, including ZachXBT and TRM Labs, suspect North Korea's Lazarus Group, which was behind the 2025 Bybit hack. Binance and law enforcement have not confirmed this.

Were my password or personal data stolen?

Binance hasn't reported any leak of user passwords or personal data. The attack targeted company wallets. Even so, it's a good moment to check that your password is unique and your 2FA is on.

Does this hack affect other exchanges or my wallet?

The hack hit Binance's own wallets. Other exchanges, such as Bybit, have said they aren't affected, and your self-custody wallet isn't affected either. Prices across the market did fall, though, and some DeFi platforms paused markets briefly as a precaution.

Why did Bitcoin fall if the hack was on Binance?

Because Binance is the biggest exchange in the world, a hack there shakes confidence across the whole market. People also worried that the attacker or Binance might sell coins. Bitcoin fell about 5% on the news.

Should I sell my crypto or move it off Binance?

We don't give personal financial advice. The decision depends on your situation. What we can say: right now you can't withdraw anyway, panic decisions often turn out badly, and when withdrawals reopen, coins you plan to hold for a long time are safer in a wallet where you control the keys.

How is CryptoSignalAPP affected?

CryptoSignalAPP doesn't hold your funds, so your app account and subscription aren't affected. Our signals are trade ideas you can follow on the exchange of your choice. If you were planning to act on a signal through Binance, keep in mind that deposits and withdrawals there are paused for now.

Where can I follow official updates?

The Binance app, the announcements page on binance.com, and Binance's verified accounts on X, such as @binance. Ignore screenshots and "insider" tips from unknown accounts.

The Bottom Line

Binance suffered what looks like the largest crypto hack ever, about $6.3 billion, apparently starting from a single compromised employee laptop. About half of it has been frozen. Binance says user funds are safe and that it will cover every loss, and it has done that before. Deposits and withdrawals are paused for now.

For you, the most important things this week are simple: stay calm, rely only on official Binance channels, ignore anyone offering "refunds" or asking for your codes, and watch the November 1 proof-of-reserves report.
