According to @EmberCN, a hacker stole about 117 million dollars from Balancer across Ethereum, Base, OP, Sonic, Polygon, and Berachain, with most of the haul being ETH liquid staking tokens. According to @EmberCN, the attacker has begun converting liquid staking tokens to ETH, including a swap of 10 osETH for 10.55 ETH roughly 20 minutes before the post. According to the ARKM entity page shared by @EmberCN at https://intel.arkm.com/explorer/entity/a1143094-5699-4e4a-a5ae-bca37094202c, a set of suspected attacker addresses is available for monitoring. According to @EmberCN, traders can track on-chain flows from the ARKM listed addresses to manage execution and liquidity risk on ETH LST pairs across the affected chains.
