<p>The incident, flagged on Sept. 18, shows how attackers are exploiting Ethereum’s convenience features to strike with little warning.</p>
<h2 id="a-gas-free-trap">A Gas-Free Trap</h2>
<p>The target lost both staked Ethereum (stETH) and Aave-wrapped Bitcoin (aEthWBTC) after approving a series of wallet prompts that looked routine. Because the signatures required no gas fees, the transaction raised no immediate suspicion. Within minutes, the assets were transferred out.</p>
<p>SlowMist founder Yu Xian noted that the victim likely believed he was just confirming harmless requests. “It felt like a couple of clicks — no cost involved — and suddenly millions were gone,” he said.</p>
<p>The attackers abused Ethereum’s Permit function, a tool created to simplify token transfers by letting users sign off-chain approvals. When combined with the TransferFrom function, that authorization allows funds to be drained directly once executed on-chain. By the time the approval shows up in a wallet interface, it’s already too late.</p>
<h2 id="bigger-trend-of-phishing-losses">Bigger Trend of Phishing Losses</h2>
<p>This whale isn’t alone. Scam Sniffer data shows August was one of the worst months on record for phishing, with over $12 million stolen from more than 15,000 addresses. Just three wallets made up nearly half of the losses, one of them losing more than $3 million in a single attack.</p>

<p>Researchers point to the rise of batch-signature schemes and malicious smart contracts as driving forces behind the surge. Attackers are increasingly relying on social engineering and deceptive approvals rather than complex exploits or costly gas wars.</p>
<h2 id="staying-safe-in-a-hostile-environment">Staying Safe in a Hostile Environment</h2>
<p>Experts are urging users to treat wallet requests with extreme caution. Unlimited approvals, in particular, remain a common entry point for theft. Even experienced investors with deep pockets are falling victim, highlighting how fragile security can be when convenience tools are abused.</p>
<p>The $6 million theft serves as another warning that in decentralized finance, the weakest link isn’t always the code — sometimes it’s the human behind the screen.</p>
