Binance Hack Explained: $6.3 Billion Stolen, How Users Are Covered and What Happens Next

The Binance hack is the largest crypto theft on record. Attackers took about $6.3 billion from Binance wallets on 29 October 2026. Binance says it will cover user losses with its SAFU fund and company money, and it reopened withdrawals on 1 November. The exchange now says about 95 percent of the stolen assets have been replaced.

Binance is one of the largest crypto exchanges in the world, and a security breach on this scale has shaken traders, investors and regulators. In this report, we explain what happened, what Binance has said, how the market has reacted and what everyday users should do now.

What Happened in the Binance Hack?

Late on Thursday 29 October 2026, attackers drained about $6.3 billion in crypto from Binance wallets. Blockchain analytics firm TRM Labs said most of the theft took place in roughly 20 minutes, with funds moved across 10 different blockchains.

Binance confirmed the scale of the incident the next day. According to CNBC, the exchange said about $6.3 billion in client assets was affected, and around $3 billion had been frozen on chain. CNBC described it as the largest crypto hack on record, far above the roughly $1.5 billion stolen from Bybit in February 2025.

Binance temporarily suspended deposits and withdrawals while it checked its systems and replaced the wallets involved. For a platform of this size, that pause alone was a major event for traders worldwide.

Importantly, the money taken came from Binance’s own hot wallets, which are the internet connected wallets used for day to day withdrawals. Binance says it is covering the loss with its own funds, so customers are not being asked to absorb it.

Timeline of Key Dates

• 29 October 2026: attackers drain about $6.3 billion from Binance hot wallets in a short burst.
• 30 October: Binance confirms the incident, says around $3 billion has been frozen and sets aside more than $6.3 billion of company money to cover losses, according to reports.
• 31 October: Binance moves 7,499 BTC out of its SAFU emergency reserve to help cover the loss.
• 1 November: Binance restarts withdrawals in phases, beginning with the Bitcoin network, then Ethereum and BNB Smart Chain.
• 3 November: Binance chief executive Richard Teng says about 95 percent of the stolen assets have been replaced, according to Reuters.

How Did the Hackers Get In?

Binance’s early findings point to a breach of its withdrawal systems rather than a theft of private keys. CNBC reported that the company found no evidence that the keys controlling its wallets had leaked, and that attackers were able to make unauthorized transfers after gaining access to internal systems.

Binance has also said the attack resembled earlier North Korea linked heists, including the Bybit theft and the KelpDAO incident in April 2026. It described patterns such as small test withdrawals through Tornado Cash to fund an operator wallet, preparation that began well before the theft, and approvals gathered in advance and then used in one burst.

The exchange says it revoked the affected address authorizations and is overhauling its withdrawal security. The full technical story is still emerging, so treat early details with care and watch for updates from Binance and independent investigators.

This type of attack is a reminder that even strong cryptography can be undone by weak points in everyday systems, such as staff devices, internal tools and approval processes.

Is Your Money Safe on Binance?

This is the question most readers want answered. Based on what Binance and the media have reported, user balances are being backed by company funds, but the situation is still developing.

What Binance says it is doing

Binance says it is using its SAFU emergency fund, part of its futures insurance fund and corporate money to replace what was stolen. Binance chief executive Richard Teng told Hong Kong Fintech Week on 3 November, according to Reuters, that about 95 percent of the stolen assets have been replenished. The remaining 5 percent are less liquid tokens that are being replaced through over the counter providers.

Did customers leave?

Some did. Teng said customers withdrew a net $4.72 billion by Monday, which is around 3 percent of the platform’s assets. Other trackers reported early net outflows of about $3.64 billion in the first hours after withdrawals reopened. Figures differ by source, but in both cases the exchange kept processing requests.

What this does not tell you

Statements from a company are not the same as independent audits. Binance has published proof of reserves data after the incident, but readers should look for further confirmation from auditors and regulators over time. Nothing here is a guarantee, and anyone holding money on any exchange carries counterparty risk.

Who Is Blamed for the Attack?

The FBI has blamed North Korea linked hackers, known in security circles as TraderTraitor, according to reports from Reuters and other outlets. North Korea has rejected the claim. As is common in cyber incidents, final attribution can take months, and different agencies may reach different levels of confidence.

North Korean groups have been linked to several large crypto thefts in recent years, including the 2025 Bybit hack. Security researchers say these attackers often rely on social engineering, patient planning and fast laundering through mixers and bridges.

Why Crypto Exchange Hacks Keep Happening

Crypto exchanges hold enormous sums in one place, so they are rich targets. The collapse of Mt. Gox in 2014, the Ronin bridge theft of about $600 million in 2022 and the Bybit hack of about $1.5 billion in 2025 all show that large pools of digital assets attract skilled attackers.

Exchanges also face a balancing act. They need hot wallets, which are connected to the internet, so customers can withdraw quickly. They also use cold storage, which is kept offline and safer but slower to use. The more money kept hot, the bigger the risk.

Attackers do not always target the blockchain itself. They often go after people and processes, such as staff laptops, cloud tools or approval workflows. Once inside, they can move fast and spread funds across many chains to make recovery harder.

How the Binance Hack Hit Bitcoin and the Wider Crypto Market

Bitcoin fell more than 4 percent to about $78,000 on Friday 30 October as the news broke, according to CNBC. By Tuesday 3 November it had slipped below $77,000, around $76,600, according to CoinGecko data cited by Blockchain Reporter.

It would be wrong to blame the hack alone. Blockchain Reporter noted that Tuesday’s drop also followed a sell off in US chip stocks and traders waiting for the first results of the US midterm elections. Bitcoin has behaved like a risk asset this year, moving with wider markets.

Ethereum was trading near $2,250 to $2,300, according to FXStreet. US spot Ethereum ETFs recorded record monthly outflows of about $1.61 billion in October, which shows institutional demand was already cooling before the hack.

Interest rates also matter for risk assets. Our report on the Fed decision to hold rates at 3.75 percent to 4 percent explains how borrowing costs can shape markets.

What Is the SAFU Fund and Why Does It Matter?

SAFU stands for Secure Asset Fund for Users. Binance created it in 2018 as an emergency reserve to compensate users in the event of a hack. The fund was about $1 billion and was converted into Bitcoin earlier this year, according to crypto news reports.

After the attack, Binance moved 7,499 BTC out of the fund, leaving about 7,500 BTC, worth roughly $580 million at recent prices. Binance says it plans to refill SAFU to about $1 billion but has not published a timeline.

SAFU is helpful, but it was never designed for a loss this large. That is why Binance also drew on its futures insurance fund and corporate treasury.

Other Exchange Problems This Week

The Binance incident was not the only security story. CoinDesk reported that Brazil’s Mercado Bitcoin halted withdrawals after about $40 million was drained across 10 chains, and that the exchange promised to cover user losses. Different companies, different details, but the same lesson: exchanges are attractive targets.

What the Binance Hack Means for Everyday Crypto Users

Exchange risk is real

When you keep coins on an exchange, you trust the company to secure them and to stay solvent. In this case Binance appears able to absorb a very large loss, which is reassuring. Many smaller exchanges could not do the same.

Self custody is not a magic fix

Moving coins to your own wallet removes exchange risk but adds personal risk. You become responsible for backups, device security and scams. Lose your recovery phrase and no company can restore your funds. The right balance depends on how much you hold and how confident you are with technology.

Beware of follow up scams

After any big hack, scammers send fake emails, texts and social posts pretending to be support teams or compensation programs. They may link to fake sites or ask for your recovery phrase. Real exchanges and wallets never need your recovery phrase. Our guide to AI voice cloning scams shows how criminals use urgency and impersonation, and the same rules apply here.

How to Protect Your Crypto: 10 Practical Steps

No method is perfect, but these habits reduce your risk a lot.

1. Use a unique, strong password for every exchange account, stored in a password manager.
2. Turn on two factor authentication with an authenticator app or a hardware key, not text messages.
3. Enable withdrawal address whitelisting so funds can only go to approved wallets.
4. Add an anti phishing code if your exchange offers one, so real emails show your code.
5. Never share your recovery phrase with anyone, including support staff.
6. Keep only what you need for trading on an exchange, and move long term holdings to a hardware wallet if you are comfortable doing so.
7. Bookmark the official exchange website and never click sign in links from messages.
8. Keep your phone and computer updated, and avoid public WiFi for sensitive logins.
9. Review account activity and switch on login alerts.
10. If you hold a large amount, spread it across more than one platform or wallet.

Final Thoughts

The Binance hack is a record breaking event, but the response so far shows how important reserves, quick action and transparency are in crypto.

Stay calm, use strong security settings and rely on official sources. Be cautious about anyone who contacts you about compensation.
