Fears of a possible Binance security breach swept through crypto markets late Thursday, October 29, 2026, after blockchain researchers and social media accounts reported roughly $2.77 billion in outflows from wallets labeled as belonging to the exchange across five blockchains. Binance had not confirmed any hack at the time of writing, and analysts stressed the transfers could still represent an internal wallet reshuffle. The unverified reports nevertheless triggered a wave of forced liquidations and a sharp sell-off across major digital assets.
On-chain alerts focused on the receiving address 0x5227f603C1eE34CE3C06eFe6477003BDfCCB2f8c. Etherscan data showed two particularly large transfers: at 20:24 UTC, about 167,464.2 ETH and 63 ERC-20 token transfers, including roughly 1.6 billion USDT, moved to that address; at 20:41 UTC, another 780 million USDC left a wallet labeled Binance: Hot Wallet 34 for the same recipient. Researchers including Spreek and developer foobar described the activity as suspicious or consistent with a possible compromise, while noting that routine wallet maintenance could not be ruled out. A funding link through Tornado Cash was alleged but not independently verified.
The market reaction was immediate. Bitcoin fell below $78,500, Ethereum below $2,250, Solana below $96, and XRP below $1.25. BNB was hit hardest among top-ten coins, dropping 6.95% to $699.85, as traders associated the token with Binance and BNB Chain. By contrast, Hyperliquid’s HYPE rose 13.73% to $91.86, with short sellers bearing most of its liquidations.
CoinGlass data showed $620.41 million in forced liquidations in a single hour and $951.23 million over 24 hours, with longs accounting for approximately 97% of the one-hour total. The broader crypto market capitalization stood at $2.67 trillion, down 1.69%.
The rumor landed in an already fragile environment. Traders recalled the Drift Protocol exploit of $285 million on Solana, Bitget’s loss of up to $387.5 million in late September, and CoinDCX’s admitted $16 million breach. Meanwhile, two Federal Reserve policymakers had backed a quarter-point rate increase, and US technology stocks sold off, with Alphabet losing about 13% and Intel falling close to 20% after hours.
Binance had not posted a confirming statement on its main X timeline when checked for this report. The recipient’s controller, the authorization behind the transfers, and any final customer-loss figure remained unverified. The episode underscored how quickly unconfirmed wallet movements can cascade into market-wide deleveraging when leverage is stretched.
