Web3 Antivirus: Single Signature Drains 316K USDC
The drainer did not exploit a contract bug — it exploited user signing habits. The reminder list is unsexy, which is exactly why it keeps working.
USDC is a fully collateralized US dollar stablecoin designed to maintain a 1:1 peg with the U.S. dollar. Issued by Circle and originally developed through the CENTRE consortium, it serves as a bridge between traditional fiat currency and digital asset markets, allowing users to move dollar-equivalent value across blockchain networks and cryptocurrency exchanges. The token operates across a broad multi-chain footprint, with native issuance and support on ecosystems including Ethereum, Solana, Base, Polygon, Arbitrum, Optimism, Avalanche, Aptos, Sui, Stellar, XRP Ledger, Hedera, NEAR, Tron, Celo, zkSync, StarkNet, and many others, making it one of the most widely deployed stablecoins in the industry. It is categorized as a fiat-backed stablecoin, with reserves held in cash and short-dated U.S. Treasuries and subject to regular third-party attestations. USDC is also recognized as MiCA-compliant, aligning it with the European Union's regulatory framework for crypto-asset markets, and is issued by a U.S.-based company. Its primary use case is providing a stable, dollar-denominated on-chain asset for trading, payments, lending, remittances, and decentralized finance applications.
