The US found the culprit of the Axie Infinity hack
The US Treasury Department believes that Lazarus hacker group from North Korea is the ones who stole more than 600 million USD from the Ronin Network bridge.
On the morning of April 15, the US Department of Finance updated the list of wallets and accounts related to embargoed organizations. In it, a wallet related to the Axie Infinity hack was listed with a note related to Lazarus, the North Korean hacker group.
Currently, the address on the group’s Ethereum network, which was marked as a “Ronin bridge intruder” after the hack, contains about 148,000 ETH, or $445 million. This wallet address sent a lot of ETH to the Tornado Cash mixer to find a way to disperse.
In a post on the official website, Ronin’s development team said that the US Treasury Department and the FBI identified Lazarus as the perpetrator of the attack after the investigation process.
“We are still in the process of adding security measures so that we can re-establish the Ronin bridge in the least risky way in the future,” said a representative of the Ronin network.
According to blockchain analysis firm Chainanalysis, Lazarus is a unit of the North Korean intelligence force, and in 2021 alone has caused seven attacks. Lazarus was also the group that attacked Sony Pictures in 2014 in connection with the movie The Interview. This group also used trojans to steal millions of dollars from ATMs in Asia and Africa in 2018.
This is the first time the US Department of Finance has put a Lazarus electronic wallet on the sanctions list, according to CoinDesk.
“Wallet verification is a clear message to attackers that when making transactions, they can be detected by the US embargo network. This also shows the commitment of the Ministry of Finance to use all possible means to stop attack groups and cybercriminals.” CoinDesk quoted a spokesman for the US Treasury Department.
The vulnerability on the Ronin bridge has been exploited by hackers since March 23, but was discovered on March 29. Hackers took away about 625 million USD worth of cryptocurrency, becoming the largest crypto hack in history if converted to USD.
Earlier, Sky Mavis, the company that developed the game Axie Infinity, has pledged to refund the amount of money that players have suffered. However, the company COO revealed to Bloomberg This process can take up to 2 years.
