(Reuters) – Blockchain project Ronin said on Tuesday that hackers were now stealing nearly $ 615 million worth of cryptocurrencies from its system, in what would be one of the largest cryptocurrency robberies ever.
The project said that on March 23, unidentified hackers stole approximately 173,600 ether tokens and $ 25.5 million coin tokens. At current exchange rates, the stolen funds are worth $ 615 million, but they were worth about $ 540 million at the time of the attack.
This makes it the second largest cryptocurrency theft ever, according to blockchain analytics firm Elliptic.
Ronin is used to run the popular online game Axie Infinity, which uses non-fungible tokens and is the largest NFT collection of all time sales volume, according to NFT market tracker CryptoSlam.
Ronin said in a blog post that the hacker had used stolen private keys ̵1; the passwords needed to access cryptocurrencies – to make ends meet.
It said it had discovered the hack on Tuesday. “We work directly with various government agencies to ensure that criminals are brought to justice,” it said, adding that it was discussing with Axie Infinity how to ensure that no users’ money was lost.
