Ethereum PoW Suffers First Smart Contract Hack

The Ethereum PoW fork is off to a rocky start — one of the network’s smart contracts has endured a hack, triggering collapsing prices

Cybersecurity researchers warn similar attacks could occur on other ETHW smart contracts

ETHPoW (ETHW), the fledgling proof-of-work (PoW) Ethereum fork, has seen its first significant smart contract hack since the network split late last week.

Blockchain security infrastructure firm BlockSec first alerted users of a so-called ‘replay attack’ on Sunday, which leveraged legitimate transactions on the proof-of-stake (PoS) Ethereum blockchain alongside DeFi application Gnosis and multi-token extension OmniBridge.
