Binance Reports $6.3 Billion Security Breach Involving Compromised Laptop

Binance declared a security incident affecting approximately $6.3 billion in assets late Thursday.

The world's largest cryptocurrency exchange stated that its teams are working around the clock to resolve the issue. The company noted that the estimated total impact could rank among the largest security incidents recorded in the industry.

Binance initially reported the potential security issue without explicitly confirming that funds had been stolen. A spokesperson said user funds remained completely safe while security teams reviewed relevant information with urgency. The company promised updates through official channels once the facts were fully verified.

Technical details released on the company's X account suggested the breach originated from a compromised DevOps engineer's laptop. This allowed an attacker to access a service container and submit unauthorized withdrawal transactions. Binance stated it found no evidence of any wallet private key leak.

The exchange worked with blockchain partners to freeze affected assets. Roughly $3 billion in assets were frozen on-chain at the time of the report. Binance also suspended all deposits and withdrawals temporarily to conduct security checks and cooperate with law enforcement.

Stablecoin providers moved quickly to secure their own positions. Jeremy Allaire, co-founder and CEO of Circle, wrote that the company froze more than $800 million in currency associated with the incident. This action was taken in coordination with law enforcement. Paolo Ardoino, CEO of Tether, announced the freezing of more than $1.5 billion in currency related to the potential hack.

Market reactions followed the news. The price of bitcoin dropped 3.2% on Thursday evening, falling below the $79,000 mark. Changpeng Zhao, the platform's founder, posted on X that user funds were safe. He described the incident as looking like a hack on Binance. Zhao added that, as a shareholder, he expected all user funds to be fully covered.

Zhao founded Binance in 2017. He pleaded guilty to a felony in 2023 for failing to prevent money laundering and stepped down as CEO. President Donald Trump pardoned him in 2025. Zhao was released from prison last year after sentencing for violating the Bank Secrecy Act. He was the first individual sentenced to prison time for violations of that law. Prosecutors noted that no one had previously violated the regulations to the extent Zhao did. Zhao and Binance have supported certain Trump family crypto enterprises.
