Earlier in July, unknown attackers targeted the Poly Network and issued tokens worth tens of billions of dollars across several blockchains.

According to PeckShield, at one point the hackers’ wallet held assets totaling $42.8 billion.

According to experts, the hackers managed to compromise three of the four private keys of the multisignature addresses used to control the smart contract.
