In one of the largest cryptocurrency thefts so far, a threat actor has ostensibly exploited a vulnerability to steal $600 million from a blockchain finance platform.
The creators of Poly Network, a “DeFi” or decentralized finance platform that works across blockchains, said on Tuesday that a hacker made off with about $600 million in cryptocurrencies.
The Poly Network team said: “The amount of money you hacked is the biggest one in defi history. Law enforcement in any country will regard this as a major economic crime and you will be pursed. It is very unwise for you to do any further transactions. The money stole is from tens of thousands of crypto community members, hence the people. You should talk to us to work out a solution.”
Poly Network listed three addresses the assets were moved to.
The team pleaded that they urge miners of affected blockchain and crypto exchanges to ban token coming from the above addresses.
And it seems that at least a small amount of the funds have been returned. Poly Network posted on Twitter “you are moving things to the right direction” and said that it had received more than $1m back.
A little later, it posted again saying: “So far, we have received a total value of $4,772,297.675 assets returned by the hacker. ETH address: $2,654,946.051 BSC address: $1,107,870.815 Polygon address: $1,009,480.809.”
According to Poly Network, “the hacker exploited a vulnerability between contract calls, exploit was not caused by the single keeper as rumored.”
