Security firm: FOOMCASH suffers copycat attack with losses of approximately $2.26 million

PANews reported on February 26 that blockchain security firm BlockSec detected that the Base and Ethereum networks' FOOMCASH contracts suffered copycat attacks. The attack method was identical to the previous Veil Cash vulnerability, where attackers exploited a verification key misconfiguration to forge zkSNARK proofs, resulting in a total contract loss of approximately $2.26 million. Among them, a single attack transaction on Base caused a loss of about $427,000, while a related transaction on Ethereum involving approximately $1.83 million is suspected to be a white-hat rescue operation.
