Ethereum may be vulnerable to the vantage point according to Dan Robinson, a research partner at the crypto-active investment firm Paradigm.

Robinson said in a blog post, the design of the Bitcoin Era mempool, or a set of unconfirmed transactions, is where the vulnerability lies. He said that arbitration bots monitor pending transactions in the Ethereum mempool and try to take advantage of beneficial opportunities created by them.

Arbitration bots generally look for specific types of transactions in the mempool (such as a transaction in a DEX or an update to an Oracle) and try to exploit them according to a predetermined algorithm. Advantage seekers look for any transaction that they can profit from to copy and replace the addresses with their own. They can even execute the transaction and copy profitable internal transactions generated by their execution trail.

The rescue plan
Robinson explained that he devised a plan to extract the money in cooperation with a team of smart contract engineers and another team of security engineers at Ethereum. The plan was to confuse the transaction so that the bots could not detect that there was a connection to the Uniswap pair.

But despite the efforts made, the plan was not successful and the money was taken by the profiteers.

He concluded his publication by stating the lessons he learned from this experience and also by warning the miners of a similar fate if they do not pay much attention.
