Binance, one of the world's largest cryptocurrency exchanges and blockchain ecosystems, has estimated the financial impact of a security breach at $6.3 billion and pledged to reimburse affected users.
In a statement, Binance said its preliminary investigation suggests the incident may have involved a compromised laptop belonging to a DevOps engineer. This allegedly allowed an attacker to access a service container and submit unauthorised withdrawal transactions.
The company said it had found no evidence that wallet private keys were leaked.
“We will share a detailed technical post-mortem once the investigation is complete and the facts are fully verified.
“The estimated total impact sits at around $6.3 billion. We have worked with blockchain partners to freeze affected assets, with approximately $3 billion frozen on-chain so far,” a Binance spokesperson said.
The exchange said it would cover all losses through its Secure Asset Fund for Users and company funds, adding that user funds remained safe.
Binance also said it would publish an updated Proof of Reserves once remediation work was complete.
As an immediate precaution, the company temporarily suspended deposits and withdrawals while it reviewed the security of its withdrawal service and related addresses.
It also revoked authorisation for the affected address and engaged law enforcement agencies and blockchain intelligence partners to trace and recover the funds.
“Our teams are working around the clock to resolve this issue safely and thoroughly. We are working closely with our law enforcement partners to confirm the identity of these criminals and bring them to justice,” the spokesperson said.
The incident comes as Binance continues to expand its presence across Africa, where cryptocurrency adoption and regulatory scrutiny are increasing.
In August 2024, Binance introduced mobile money-based cryptocurrency trading in Ghana, Tanzania, Uganda and Zambia through its One Click Buy and Sell feature.
In October 2025, the exchange said it had expanded direct fiat channels and peer-to-peer trading to more than 30 African countries, supporting local currencies and payment methods.
However, its continental expansion has taken place against a backdrop of regulatory challenges, particularly in Nigeria.
In June 2023, Nigeria's Securities and Exchange Commission ordered Binance Nigeria Limited to stop soliciting local investors, saying the company was neither registered nor regulated by the commission.
In March 2026, Binance and Nigerian authorities were reportedly exploring an out-of-court settlement in a multi-billion dollar tax dispute.
The latest security incident adds another challenge for the cryptocurrency exchange as it seeks to maintain user confidence and strengthen its position in global and African digital asset markets.
