The Federal Bureau of Investigation published a statement on the investigation results associated with the $600 M hack of the Ronin Network. Ronin is an Ethereum sidechain built for the play-to-earn game, Axie Infinity.
According to the statement, the FBI was able to confirm that the hackers behind the attack were Lazarus Group and APT38 from North Korea, officially the Democratic People's Republic of Korea (DPRK). FBI added that it cooperates with the Treasury and other U.S. government agencies to prevent illicit activities from North Korea, including cyberattacks and cryptocurrency thefts.
The US Treasury Department announced sanctioning the address that received the stolen funds. On April 15, the Treasury announced that it added the address to The Specially Designated Nationals and Blocked Persons List (SDN list).
Ronin published a blog post saying the team is in the process of making the network more secure before redeploying the Ronin Bridge to prevent future risks.
The redeployment is likely to take place by the end of this month. However, the date isn't certain and can be changed.
