Techub News reports that, according to PeckShield monitoring, Matcha Meta has reported a security vulnerability in SwapNet. Users who have not enabled the "one-time authorization" feature are at risk. To date, approximately $16.8 million worth of encrypted assets have been stolen; among them, on the Base chain, attackers have exchanged about 10,500,000 USDC for approximately 3,655 Ethereum and have begun transferring funds cross-chain to the Ethereum mainnet. Relevant risk mitigation suggestions are subject to future announcements from the project team and aggregators. Users may consider checking and revoking permissions outside of the "one-time authorization" contracts.
