The hack run lower
The hack was the effect of a spear phishing attack on the former Sky Mavis worker (developers of Axie Infinity). Unhealthy actor could leverage the employee’s credentials to access Sky Mavis’s four validator nodes from as many as nine within the Axie/Ronin ecosystem.
This alone wasn’t enough to complete any damage, but “the attacker found a backdoor through our gas-free RPC node, that they mistreated to obtain the signature for that Axie DAO validator.”
“This traces to November 2021 when Sky Mavis requested the aid of the Axie DAO to distribute free transactions because of an enormous user load. The Axie DAO allowlisted Sky Mavis to sign various transactions on its account. It was stopped in December 2021, however the allow list access wasn’t revoked,” the report reads.
Following a hack, big changes are now being implemented at both Sky Mavis and also the Ronin Network.

They is all about 80% through upgrading Ronin bridge smart contracts, they’ll be reworking the backend, moving all pending withdrawals and launching a validator dashboard that “allows for approving large transactions and adding/removing new validators.”
“The Ronin Network bridge is presently being redesigned and can open after we are confident that it may stand the ages. We initially expected so that you can deploy the upgrade through the finish of April, but this isn’t a procedure that money can buy to hurry.”
