Binance wallets moved about $2.77 billion in crypto: what is known about the possible hack

Blockchain trackers have flagged large transfers from Binance-linked wallets across five networks, but the available data does not confirm theft. For high-risk PSPs, the distinction matters: big internal movements can look like an incident long before anyone can prove whether funds actually left the exchange’s control.

1. According to Bitcoin Sistemi, the total value of the transfers was about $2.77 billion, based on on-chain data across five blockchain networks. That figure is an estimate of the moved assets, not a confirmed loss amount.
2. BeInCrypto reported that an address labeled Binance 14 sent roughly 167,500 ETH and dozens of other tokens, including about 1.6 billion USDT. Later, the Binance 16 wallet sent another roughly 28,000 ETH to the same address. After that, the recipient moved about 195,500 ETH onward to another address, which is what drew attention from blockchain researchers.
3. The thing is, large transfers by themselves do not prove a hack. Exchanges often move assets between their own wallets for liquidity management and custody purposes. To establish theft, someone would need to show that the assets ended up under the control of an outside party.
4. The $2.77 billion figure should be treated as the number from Bitcoin Sistemi’s report, not as the final total of all related activity. When comparing estimates, the details matter: which networks were included, which addresses were tracked, and whether the same assets were counted again after being moved to a new wallet.
5. Binance founder Changpeng Zhao (CZ) separately posted a cybersecurity warning, as reported by Gate News. He urged people not to click links in emails or download attachments, even if the message appears to come from someone they know. Zhao said the sender’s computer may be infected with malware without the sender’s knowledge, but that warning is not confirmation of a Binance breach.

For PSPs, acquirers, and banks that work with crypto flows, this is a familiar pattern: on-chain movement can trigger headlines fast, while the factual question remains open until the control of the funds is established. At the time of writing, the available reports do not allow a final conclusion on why the transfers happened or whether users suffered losses.
