This decision was what allowed Jump Crypto to obtain a court order requiring the Oasis platform to "upgrade" a smart contract in such a way that Jump Crypto could remove stolen funds from where the hacker had placed them on the Oasis protocol. Oasis released a defensive statement, writing that their cooperation in the recovery was "only possible due to a previously unknown vulnerability in the design of the admin multisig access", and that "we will be making no further comment at this time". Oasis is a frontend for the MakerDAO project, which was originally started as part of MakerDAO but later spun into a separate entity, though it still appears to enjoy preferred status by MakerDAO.
The stolen funds in question were the proceeds of the February 2022 Wormhole bridge exploit, in which attackers stole 120,000 wETH (then ~$326 million; now $192 million). After the hack, Wormhole's parent company Jump Crypto plugged the hole left by the hack with their own funds. Since then, the attackers have been moving the funds throughout the cryptocurrency ecosystem, even taking out a highly-leveraged position on in Lido-staked Ether last month.
Ultimately, Jump was able to recover around $140 million via their "counter-exploit". While many celebrated the recovery, some were concerned about the precedent of a so-called defi platform changing a smart contract to remove funds from a wallet at the direction of a court. Some described the upgradability as a "backdoor". "If they'd do it for Jump, what does that say about possible coercion via state actors?" wrote one trader on Twitter.
