Binance Investigates Potential Multibillion-Dollar Security Breach
Binance is investigating a potential multibillion-dollar security breach involving one of its Ethereum wallets. This investigation was prompted by suspicious transfers that led stablecoin issuers Tether and Circle to freeze nearly $2.36 billion in assets. A spokesperson for Binance stated that the exchange is looking into reports of a possible security issue but has not confirmed any impact on user funds. The security teams are currently reviewing the activity and will provide updates as more information becomes available.
Concerns about the situation were initially raised by blockchain researcher Spreek, who reported on X that assets from a Binance-linked Ethereum wallet had been transferred to a newly created address through a contract call allegedly funded by Tornado Cash. Following this, Spreek noted that wallets associated with these transfers began selling Tether (USDT) on decentralized exchanges.
Blockchain analytics platform Arkham Intelligence later identified a collection of wallets labeled "binance-hacker-1029" that reportedly hold approximately $5.84 billion in digital assets. This figure reflects the wallets' reported holdings and does not confirm the amount of stolen funds.
Binance's Response to the Alleged Hack
Binance co-founder Changpeng Zhao indicated that the activity appears to be a hack. He mentioned that Tether and Circle had frozen approximately $971 million and $823 million, respectively, in response to the incident. Zhao expressed confidence that all user funds would be fully covered.
Approved for Dissemination
Blockchain security firm Blockaid also reported identifying around $3.3 billion in suspicious transfers involving Binance-linked wallets across Ethereum, Arbitrum, and Avalanche. Shortly after these findings, Tether and Circle announced on X that they had frozen a combined total of $2.36 billion in tokens related to the suspected breach.
Circle CEO Jeremy Allaire confirmed that the company had frozen more than $800 million in USDC in coordination with law enforcement and pledged ongoing support for the investigation. Tether CEO Paolo Ardoino also announced that over $1.567 billion in USDT linked to the potential exploit had been frozen, emphasizing that protecting the industry and partners is their main priority.
