How Hackers Manipulated DeFi Systems to Drain Millions

[tradelikepro]

The Drift exploit wasn’t just a hack—it was a multi-stage manipulation of decentralized finance infrastructure. Attackers introduced a fake asset (CVT), artificially boosted its trading activity, and tricked the protocol’s oracles into recognizing it as legitimate collateral.

Once trusted, they used pre-approved permissions to withdraw real assets like USDC, draining funds in minutes. Blockchain analysis linked early activity to Tornado Cash, a tool often used to obscure fund origins. The sophistication of this attack shows how DeFi vulnerabilities increasingly stem from social engineering and system design flaws—not just code bugs.

at this point the biggest vulnerability is just humans being humans

this wasn’t just a smart contract issue, it was a full system-level failure across trust, oracles, and permissions
