February 17, 2020 bZx loses $620,000 of equity in hack.

Over the weekend, an attacker managed to exploit a “logic bug” in the non-custodial margin lending protocol’s coding, generating $350,000 in profit for the hacker and causing a loss nearly double that for the protocol. The attack involved a complex DeFi transaction routed through Compound, dYdX, Kyber, Uniswap and bZx’s Fulcrum. Third-party bots were then able to claim a large portion of the profit from an imbalance in Uniswap, unrealized by the hacker.
