[42DAO Suffers $912,000 Loss Due to BTCB Oracle Price Anomaly] SlowMist issued a warning that 42DAO was attacked due to an abnormal BTCB oracle price, resulting in a loss of approximately $912,000. The attacker exploited the abnormally low BTCB price provided by the Median Oracle and executed the attack through the Spotter contract's poke mechanism and the Dog contract's bark mechanism. The Spotter module lacked checks for price deviation, maximum drawdown limits, and minimum price protection, which allowed the abnormal low price to be written into the Vat. The Dog module, without liquidation delays and oracle price verification, initiated instant liquidations on multiple BTCB vaults. The attack was carried out in a single transaction, with the attacker profiting from liquidation arbitrage.
