Jump Crypto, a Web3 infrastructure company, and Oasis.app, a decentralized finance (DeFi) platform, teamed up to perform a "counter exploit" against the Wormhole protocol hacker. As a result of their efforts, they were able to recover $225 million worth of digital assets and transfer them to a secure wallet.

  According to the report from Blockworks,  Jump Crypto and Oasis were able to recover 120.69k wstETH and 3.21k rETH, which amounted to $225M of assets lost in the notorious Wormhole Exploit that happened a year ago. The team performed a "counter exploit" by securing the stolen funds through an upgradable proxy contract on the Oasis protocol, and then transferring them to a new wallet.

Oasis confirmed in a blog post on February 24th that a "counter exploit" had been conducted. The post stated that they first became aware of the possibility to assist in the retrieval of the assets after a Whitehat group reached out to the team on the evening of Thursday 16th February 2023. 

"What occurred on 21st February 2023 was only possible due to a previously unknown vulnerability in the design of the admin multisig access. We stress that this access was there with the sole intention to protect user assets in the event of any potential attack, and would have allowed us to move quickly to patch any vulnerability disclosed to us." Oasis said in the post,  "It should be noted that at no point, in the past or present, have user assets been at risk of being accessed by any unauthorised party."
