The attacker obtained  24,830 ETH -- an amount worth roughly $75.8 million as of press time. The remainder of the exploited funds were in the form of drained liquidity connected to the protocol's governance token.

As for how the exploit was carried out, signs indicate that the exploiter used an accumulation of governance tokens -- obtained through a flash loan --  to create a fake protocol improvement proposal to gift funds held in Beanstalk to an address used to raise donations for the government of Ukraine. 

Update: This article has been amended to clarify that the hack amount was $182 million based on the latest findings.
