The hackers behind the March 23 theft of roughly $625 million worth of cryptocurrency from the Ronin blockchain are based in North Korea, according to a new announcement from the FBI. The federal law enforcement agency claims the Lazarus Group, North Korea’s most notorious hacker gangis laundering the money for Kim Jong Un’s regime and the US Treasury is working to stop the flow of funds however it can.

“The FBI continues to combat malicious cyber activity including the threat posed by the Democratic People’s Republic of Korea to the US and our private sector partners. Through our investigation we were able to confirm Lazarus Group and APT38, cyber actors associated with the DPRK, are responsible for the theft of $620 million in Ethereum reported on March 29th,” the FBI said in a statement late Thursday

“The FBI, in coordination with Treasury and other US government partners, will continue to expose and combat the DPRK’s use of illicit activities – including cybercrime and cryptocurrency theft – to generate revenue for the regime,” the FBI statement continued.

The hackers made off with about 173,600 etheraccording to the Ronin Network, and 25.5 million USDC, a stablecoin pegged to the US dollar. Lazarus Group has allegedly been behind the theft of over $1 billion in crypto and cash over the years, becoming a successful source of revenue for North Korea’s heavily sanctioned economy.

The US Treasury has sanctioned the address that received the stolen crypto, but it’s currently being laundered through Tornado Cash, a service that allows people to obfuscate where crypto has come from. The hackers who stole $34 million from Crypto.com back in January also used Tornado Cash and it’s not clear whether federal authorities are trying to get it shut down.

The theft, believed to be the largest in crypto history, exploited a vulnerability in the Ronin network, which runs the incredibly popular NFT game Axie InfinitySomehow, the hack wasn’t noticed by the folks at Ronin until six days later

The Axie Infinity game is a so-called play-to-earn model where players must first buy NFTs of cartoon characters which they can then use to earn crypto by playing games for hours on end. The game is incredibly popular in the Philippines where it became a stream of income for people during covid-19 pandemic lockdown.

We are still in the process of adding additional security measures before redeploying the Ronin Bridge to mitigate future risk,” Ronin Network said in a statement on Thursday

Expect the bridge to be deployed by end of month. Security comes first. The timeline is subject to change based on the implementation time of several security measures,” the statement continued.
