Binance Investigates $6.3 Billion Security Breach

Binance, the world's largest cryptocurrency exchange, reported a security incident with an estimated financial impact of approximately $6.3 billion on Thursday.

The company stated it is actively investigating the event, with founder Changpeng Zhao describing the situation as appearing to be a hack. Binance has temporarily suspended all deposits and withdrawals to conduct security checks and freeze funds while working with law enforcement agencies.

A Binance spokesperson said in a statement that user funds remain completely safe. The company noted that its teams are working around the clock to resolve the issue and will provide verified updates through official channels.

Initial findings suggest the breach involved a compromised laptop belonging to a DevOps engineer. This allowed an attacker to access a service container and submit unauthorized withdrawal transactions. Binance added that it found no evidence of a wallet private key leak.

The exchange has collaborated with blockchain partners to freeze affected assets. Roughly $3 billion in value has been frozen on-chain so far. Binance indicated it will share further technical details once the investigation is complete and facts are fully verified.

Major stablecoin providers responded quickly to the incident. Tether CEO Paolo Ardoino announced on social media that the company froze the equivalent of more than $1.5 billion in currency related to the potential Binance exchange hack. Circle co-founder and CEO Jeremy Allaire stated that his firm froze over $800 million in associated currency in coordination with law enforcement.

Market reaction was immediate, with the price of bitcoin dropping 3.2 percent on Thursday evening to fall below the $79,000 mark.

Zhao, who stepped down as CEO in 2023 after pleading guilty to a felony regarding the platform's failure to prevent money laundering, posted on X that user funds are safe. Although he no longer manages the company, he said that as a shareholder he expects all user funds to be fully covered.

Zhao was released from prison last year after serving a sentence for violating the Bank Secrecy Act. He was the first person sentenced to prison time for violations of that law, which mandates that U.S. financial institutions monitor transactions and report suspicious activity. President Donald Trump pardoned Zhao in 2025.

Zhao and Binance have been key supporters of several cryptocurrency ventures associated with the Trump family.
