How Was Binance Hacked? FBI Confirms North Korean Unit Stole $6.3 Billion

The Binance hack has become one of the biggest security incidents in cryptocurrency history. More than $6.3 billion in digital assets were reportedly stolen from the world's largest crypto exchange in an attack that took place around October 29, 2026.

On October 31, the Federal Bureau of Investigation (FBI) publicly attributed the attack to a North Korean cybercrime unit known as TraderTraitor. The incident triggered a temporary suspension of transactions, followed by significant customer withdrawals when Binance began restoring services.

By November 1, customers had withdrawn a net $3.64 billion from the exchange. Binance, meanwhile, said it had replaced approximately 95% of the stolen assets and remained committed to covering the full financial impact.

So, how was Binance hacked, what role did North Korea play, and are customer funds safe?

Key Takeaways

• The FBI blamed North Korea: The agency attributed the $6.3 billion theft to TraderTraitor, a North Korean state-linked cyber unit.

• Binance replaced around 95% of stolen assets: The exchange used corporate funds, its Futures Insurance Fund, and SAFU resources to cover the losses.

• Withdrawals have resumed in phases: Binance reported $3.64 billion in net customer withdrawals on November 1 as services returned.

How Was Binance Hacked?

The attack reportedly occurred on or around October 29, 2026, affecting Binance's global centralized exchange, Binance.com. Binance's US-facing platform said it was not affected.

According to the exchange's preliminary investigation, the incident may have started with a compromised laptop belonging to an engineer. The suspected breach allowed attackers to gain access that could be used to initiate unauthorized transactions.

However, Binance has not publicly provided a complete technical breakdown of the attack. That means the exact entry point, security weakness, and full sequence of events remain subject to further investigation.

This distinction matters because several discussions have attempted to connect the incident to an EIP 7702 exploit or an Ethereum upgrade vulnerability. There is currently no verified evidence in the available reports establishing either as the cause of the Binance hack.

The incident should therefore be understood as a reported compromise involving Binance's internal security environment, rather than a confirmed vulnerability in Ethereum itself.

FBI Confirms North Korea Is Responsible for the $6.3 Billion Binance Crypto Hack

On October 31, the FBI released an official cyber alert stating that North Korea was responsible for stealing more than $6 billion in virtual assets from Binance.

The agency identified the operation as TraderTraitor, a name associated with North Korean cyber activities targeting cryptocurrency platforms.

The FBI also reported that the attackers had been converting stolen assets primarily into Ethereum (ETH). It warned that the funds could undergo further laundering through decentralized finance (DeFi) platforms and instant swap services.

The agency published wallet addresses connected to the operation and urged cryptocurrency exchanges, blockchain infrastructure providers, and other industry participants to block transactions involving those addresses.

TraderTraitor has also been associated with the Lazarus Group, a name frequently linked to North Korean cryptocurrency thefts. The group's previous high-profile activity included the 2025 Bybit incident, in which approximately $1.5 billion was stolen.

The connection between the North Korea Binance hack and these earlier incidents highlights the continuing threat posed by state-linked cyber operations against the digital asset industry.

Binance Withdrawal Status: Why Did Customers Withdraw $3.6 Billion?

Binance temporarily suspended transactions following the attack while it investigated the incident and conducted security checks.

The exchange subsequently reopened withdrawals in phases, beginning with major cryptocurrencies such as Bitcoin and Ethereum. Additional assets and services were expected to return as their respective checks were completed.

According to Binance, between 06:00 and 15:30 GMT on November 1, the exchange processed:

• $4.649 billion in withdrawals.

• $1.01 billion in deposits.

• Approximately $3.64 billion in net outflows.

Binance said the initial withdrawal spike later declined and began stabilizing. The net outflow represented just over 2% of its reported $171 billion in assets under management.

These figures help explain the market's reaction, but they should not be confused with the $6.3 billion stolen in the attack. The former measures customer activity after services resumed; the latter refers to the reported value of assets taken during the breach.

For users searching for the Binance withdrawal status, the practical point is that withdrawals have resumed in phases, rather than all services returning simultaneously. Customers should check the exchange's official announcements for asset-specific availability.

Binance Compensation Plan: Where Will the Money Come From?

One of the biggest concerns after the incident was whether Binance could replace the stolen funds.

The exchange said it had already covered approximately 95% of the affected assets. It also reiterated its commitment to covering the full financial impact of the incident.

Binance reportedly used several sources to replenish customer assets:

• Its corporate treasury.

• The Futures Insurance Fund.

• The Secure Asset Fund for Users (SAFU).

The SAFU fund Binance maintains is designed as an emergency reserve to protect users under certain circumstances. Binance said it had reserved more than $6.3 billion to address the incident and planned to replenish SAFU toward its previous $1 billion level.

Binance and industry partners also worked to identify and freeze affected assets. Reports indicated that around $3 billion in assets had been located, with efforts continuing to restrict their movement.

However, stolen crypto frozen does not automatically mean all affected assets have been recovered. Identifying wallet addresses, freezing assets, and returning funds to their rightful owners are separate stages.

Is Binance Safe After the Hack?

The incident raises legitimate questions about Binance user fund safety, even after the exchange pledged to replace the stolen assets.

The exchange's reported compensation provides reassurance that customers are not being asked to absorb the full financial loss. Nevertheless, the attack demonstrates that even major centralized platforms remain exposed to sophisticated cybersecurity threats.

For users, several precautions remain relevant:

• Enable two-factor authentication and withdrawal security controls.

• Avoid clicking suspicious links or responding to unsolicited messages.

• Verify wallet addresses and withdrawal details before confirming transactions.

• Consider keeping long-term holdings in a wallet where you control the private keys.

• Follow official exchange announcements when services are suspended or restored.

The incident also puts public attention on Binance leadership, including CEO Richard Teng. Searches for Richard Teng Binance hack reflect interest in the exchange's response and accountability, although the available reports do not provide a detailed personal statement from him about the technical cause.

The broader crypto market reaction has also drawn attention. Discussions around a possible crypto market crash November 2026 should be treated carefully: the reported withdrawal spike and market pressure do not, by themselves, establish that a market-wide crash has occurred.

Conclusion

The $6.3 billion Binance hack represents a major test for the cryptocurrency industry's security and crisis response. The FBI has attributed the attack to North Korea's TraderTraitor unit, while Binance says it has replaced approximately 95% of the stolen assets and remains committed to covering the rest.

Although withdrawals have resumed and customer outflows have begun stabilizing, questions remain about the full technical details of the breach and the recovery of affected assets. For the wider crypto market, the incident is another reminder that exchange security and independent asset custody deserve serious attention.
