A user: Binance account 5 unauthorized flash trades occurred within 97 seconds

A user stated that on November 8, 2026, while exchanging small cryptocurrencies for USDC on Binance, their account experienced 5 unauthorized flash exchanges within 97 seconds. The transactions they listed included 2.331 BTC exchanged for USDC, as well as two rounds of back-and-forth exchanges totaling approximately 260,000 USDC and EUR, which collectively reduced about 10,044 USDC, with each round close to 2%.

A user claimed that Binance customer service insisted that the related transactions originated from their commonly used iPhone but did not provide sufficient records to prove that the user actually authorized them, nor did they adequately explain the exchange rate differences. They publicly raised three questions, including who initiated the transactions, why the price difference was significant, and who benefited economically, and published the complaint number CC10319344, requesting intervention from He Yi, CZ, and the Binance security team. They added that there were a total of 6 transactions in the screenshots, and only the EDEN exchange for USDC at 02:21:13 was operated by them, while the other 1 BTC exchange and 4 USDC and EUR exchanges were neither initiated nor authorized by them, with the EDEN exchange they operated occurring between the aforementioned 5 transactions.
