Unusually large withdrawals were made from Stake to an account with no previous activity, including $3.9 million in Tether and $9.8 million in Ether.
Crypto gambling site Stake has experienced $16 million in withdrawals on Sept. 4 in what security platform Cyvers Alerts is calling “suspicious transactions.” The withdrawing account has been labeled “Stake.com Hacker” by Etherscan, implying that the drained funds may be the result of a stolen private key.

Blockchain data shows very large withdrawals from Stake.com contracts into the alleged attacker’s account. The first transaction occurred at 12:48 p.m., transferring approximately $3.9 million worth of Tether (USDT) stablecoin from Stake to the attacker’s account. The next two transactions removed 6,001 Ether (ETH), worth approximately $9.8 million at the current price. The attacker continued to remove tokens over the next few minutes, including approximately $1 million USD Coin (USDC), $900,000 worth of Dai (DAI) stablecoin, and 333 Stake Classic (STAKE) ($75.48). Cyvers has estimated the total value of crypto drained at $16 million.
After draining the funds, the alleged attacker distributed them to multiple accounts. At the time of publication, Stake has not made an announcement regarding the suspicious withdrawals.
