Venus Protocol's $3.7M Heist: How a Nine-Month Plot Exploited a Known Vulnerability on BNB Chain
A security audit flagged the exact attack vector months earlier. The team dismissed it. On Sunday, an attacker walked away with $3.7 million.
Venus Protocol, the dominant lending platform on BNB Chain with roughly $1.47 billion in total value locked, suffered a devastating price manipulation exploit on March 15, 2026. The attacker targeted THE — the native token of decentralized exchange Thena — inflating its price from $0.27 to nearly $5 through a carefully orchestrated loop of deposits, borrows, and purchases. The result: over $3.7 million drained in BTC, CAKE, USDC, and BNB, with approximately $2.15 million persisting as unrecoverable bad debt.
What makes this attack remarkable is not just its scale, but the patience behind it — and the fact that the vulnerability was hiding in plain sight.
