Cross-chain protocol Poly Network said its services would remain temporarily suspended after a hacker exploited 57 crypto assets on ten blockchains, including Ethereum (ETH), BNB Chain, Polygon (MATIC), Avalanche (AVAX), Metis, Optimism (OP) and others on July 2.
Community debate extent of the Poly Network attack
DeFi security expert Arhat stated that a smart contract vulnerability on the Poly Network cross-chain bridge caused the attack.
Arhat explained that the hacker created a malicious parameter that contained a fake validator signature and block header. This allowed them to bypass the verification for the parameters and issue billions of tokens from the Poly Network Ethereum pool, which was transferred to their address.
Arhat said:
“At one point, the hacker’s wallet held over $42 billion worth of tokens (on paper) immediately following the hack. Impressively, despite the magnitude of this hack, the hacker was only able to convert a small portion of these tokens SHIB, COOK, RFu
