All of the AXS, RON, and SLP on Ronin are safe now.”
The team additional explained that the project uses 9 validator nodes to run Ronin, and so as to deposit or withdraw, 5 out of 9 ar required to method a dealings.
“The hacker managed to induce management over Sky Mavis’s four Ronin Validators and a third-party validator go past Axie DAO,” Sky song thrush aforementioned. “The validator key theme is ready up to be redistributed so it limits AN attack vector, almost like this one, however the wrongdoer found a backdoor through our gas-free RPC node, that they abused to induce the signature for the Axie DAO validator.”
What’s worse is that Sky song thrush notes that the wrongdoer got away with it as a result of a modification created back in Gregorian calendar month 2021, and that they discontinued the “Axie DAO allowlisted” theme the terribly next month.
However, the “allowlist access wasn’t revoked” the team aforementioned, and Sky song thrush extra that “once the wrongdoer got access to Sky song thrush systems they were able to get the signature from the Axie DAO validator by mistreatment the gas-free RPC.” Sky Mavis’s post mortem continued:
We have confirmed that the signature within the malicious withdrawals match up with the 5 suspected validators.

That specific attack against the hollow bridge saw the loss of $320 million, however the funds were replaced by Jump Crypto. Sky song thrush explained on weekday that the team is functioning with enforcement so as to “ensure the criminals get delivered to justice.”
Moreover, the team is within the method of discussing with stakeholders and talking regarding the way to confirm users ar remunerated. “Sky Mavis is here for the long run and can still build,” the team’s post mortem concludes.
