Ethereum-based non-custodial lending protocol Eurler finance faced a flash loan attack on March 13, with the attacker managing to steal millions in DAI, USDC, staked Ether (StETH) and wrapped Bitcoin (WBTC).

According to on-chain data, the exploiter carried out multiple transactions stealing nearly $196 million as per the last update. On-chain data analytic firm Certik data indicates the exploiter has stolen nearly 43 million in decentralized stablecoin DAI and nearly 93,800 in wrapped Ether (wETH). The ongoing attack has already become the largest hack of 2023. 

The breakdown of stolen funds are as follows:

According to another crypto analytic firm Meta Seluth, the attacker is correlated with the deflation attack that occurred one month ago. The attacker use the Multichain bridge to transfer the funds from BSC to Ethereum and launched the attack today!

Euler Finance raised $32 million in a funding round last year that saw participation from the likes of FTX, Coinbase, Jump, Jane Street and Uniswap.

Euler Finance became quite popular for offering liquid staking derivatives (LSDs) services. LSDs are a relatively new type of token that enables stakers to augment potential returns by unlocking liquidity for their staked cryptocurrency, such as ETH. Currently, LSDs make upto 20% of total value locked in centralized finance protocols.

This is a developing story, and further information will be added as it becomes available.
