A Japanese cryptocurrency exchange Liquid has become the latest victim of a cyberattack that has seen hackers make off with an estimated amount of $97 million in stolen assets.

The funds include $45 million in Ethereum tokens, which the culprit is converting into Ether using decentralized exchanges to avoid them being frozen, according to Elliptic, a crypto tracking firm that is assisting Liquid in its investigation.

The incident is the second major crypto heist to take place this month. Earlier, a hacker stole — and quickly returned — about $611 million in in Ethereum, Shiba Inu and other digital currencies from the decentralized Poly Network finance platform.
