A blockchain is where encrypted data can be supposedly transferred securely, making it nearly impossible to duplicate or counterfeit.

The site said the hackers have taken thousands of digital tokens such as Ether.

“The amount of money you hacked is the biggest one in the defi history,” Poly Network said in a tweeted message to the thieves, using a reference to decentralised finance involving cryptocurrency.

The platform added that the money as stolen from “tens of thousands of crypto community members”.

Poly Network threatened police involvement, but also pleaded with the hackers to “work out a solution”.

The site said an initial probe investigation found a hacker exploited a “vulnerability between contract calls”.

About $267m of Ether currency has been taken, $252m of Binance coins and roughly $85 million in USDC tokens.

Once the hackers stole the money, they began to send it to various other cryptocurrency addresses, CNBC reports.

Researchers at security company SlowMist said a total of more than $610 million worth of cryptocurrency was transferred to three different addresses.

SlowMist said that their researchers had “grasped the attacker’s mailbox, IP, and device fingerprints” and are “tracking possible identity clues related to the Poly Network attacker”.

The researchers concluded that the theft was “likely to be a long-planned, organized and prepared attack”.


The site urged cryptocurrency exchanges to “blacklist tokens” coming from the addresses that were linked to the hackers.

Cryptocurrency systems have been were developed independently, so have struggled to work in conjunction with each other.
