Flash: Binance says its teams are "actively investigating" reports of a potential security issue, after more than $2 billion in ETH and tokens left Binance-branded hot wallets on Thursday. The exchange says it has not confirmed any impact on user funds and will update through official channels. It warns users to beware of scams and unofficial links. The funds went to a newly created address, and the transaction was activated by a Tornado Cash-funded wallet, according to Etherscan data. Total reports range from about $2 billion to $2.8 billion.
