BlockBeats news on May 9th: Scam Sniffer, a Web3 anti-fraud platform, revealed that through analyzing on-chain data, approximately 300 victims had their assets worth $690,000 stolen by a malicious signature based on Permit2. Such phishing cases have rapidly increased in the past two weeks. Since Uniswap launched Permit2, there have been 669,000 addresses authorized with Permit2 on the Ethereum mainnet. As the authorization is internal to the Permit2 contract, there are currently no visual tools available on the market to revoke such authorization.
