What happened
Sandwich attack exploiting SushiMaker's fee-conversion vulnerability in the DIGG/WBTC Sushiswap pool. When Sushiswap added DIGG/WBTC to Onsen but failed to set up a bridge in SushiMaker, the attacker routed protocol fees through an illiquid pool, capturing 81 ETH in excessive slippage fees intended for xSUSHI holders.
