Binance reports $6.3 billion security breach traced to compromised engineer

Major cryptocurrency exchanges have historically relied on internal controls to secure digital assets, but a breach at the industry leader has exposed vulnerabilities in its operational infrastructure. On Thursday, Binance announced it was investigating a security incident that it estimated had an impact of approximately $6.3 billion.

The company stated that its initial investigation linked the incident to a compromised DevOps engineer's laptop. This breach allowed an attacker to access a service container and submit unauthorized withdrawal transactions. Binance noted that it found no evidence of wallet private key leaks, suggesting the attack targeted the administrative layer rather than the storage of user funds. The exchange reported that it had frozen roughly $3 billion in affected assets on-chain through cooperation with blockchain partners.

To contain the issue, Binance temporarily suspended all deposits and withdrawals. The company said its teams were working around the clock to resolve the matter and would release further technical details once facts were fully verified. A spokesperson emphasized that user funds were completely safe and that security teams were reviewing all relevant information with urgency. The company confirmed it was working with law enforcement, issuers, and blockchain intelligence firms to trace and freeze additional assets.

Stablecoin providers reacted quickly to the news. Circle co-founder and CEO Jeremy Allaire stated on X that his company froze more than $800 million in currency associated with the incident in coordination with law enforcement. Tether CEO Paolo Ardoino reported that his company froze more than $1.5 billion in currency related to what he described as a potential Binance exchange hack. These freezes represent a coordinated effort to prevent the movement of potentially stolen funds.

Changpeng Zhao, the founder of Binance, addressed the incident on social media. Although he stepped down as CEO in 2023 after pleading guilty to a felony related to money laundering failures, Zhao remained a shareholder. He posted that user funds were safe but acknowledged the incident looked like a hack. As a shareholder, he expressed the expectation that all user funds would be fully covered. Zhao had been pardoned by President Donald Trump in 2025 following his release from prison for violating the Bank Secrecy Act.

The market reacted to the news with volatility. Bitcoin prices dropped 3.2% on Thursday evening, falling below the $79,000 mark. The incident follows a period of increased regulatory scrutiny and personal legal challenges for the exchange's leadership. Binance has been a key supporter of certain Trump family crypto enterprises, adding a layer of political and economic interest to the resolution of the breach.
