An attacker successfully manipulated an oracle to drain around 10% of the liquidity pool for the Levana Protocol, an Osmosis-based perpetual futures project. This amounted to $1.146 million.
The attack was unusual in that it lasted almost two weeks, going unnoticed because it was draining pools slowly enough that the Levana team assumed it was organic activity. However, when the network became congested, the attack suddenly became more profitable — and more noticeable.
