The popular blockchain game Axie Infinity is an online game where you can earn cryptocurrency while playing. Its operator SKY MARVIS recently confirmed that hackers compromised the Ronin Network, which provides sidechain services for games, and stole around $600 million US dollar worth of ethereum.
Ronin Network stated that the hacker obtained the signature file through the backdoor program, and at the same time successfully manipulated 5 of the 9 verification transaction nodes, and forged the transaction request on March 23, and finally successfully stole the assets.
At present, the operator has contacted law enforcement and Chainalysis to study how to retrieve or reimburse the stolen cryptocurrency, and has revoked the authorization of the relevant backdoor program. The operator also stressed that existing cryptocurrencies owned by other users are still safe.
