Meter, a blockchain infrastructure company, said $4.4 million was taken during a cyberattack on the network on Saturday morning at about 9 a.m. ET. The cyberattack impacted the Meter and Moonriver networks.
During the event, 1391 ETH and 2.74 BTC were stolen. Meter halted all bridge transactions after finding a vulnerability in its code that allowed the hacker to impersonate BNB and ETH transfers by “calling the underlying ERC20 deposit function.”
Wormhole, a popular decentralized cross-chain message passing mechanism, was used to steal $324 million. Researchers discovered proof of an 80,000 ETH transfer from Wormhole, as well as a hacker selling 40,000 ETH on Solana. Users who held WETH and BNB have reportedly had compensation schemes in place.
The firms have offered the hacker $10 million in exchange for the money, as well as the same sum to anyone who can provide information “leading to the arrest and conviction of individuals responsible for the breach.”
