A Price Feed Attack is a malicious exploit targeting the external data sources, or oracles, that provide real-world price information to smart contracts on a blockchain. Attackers manipulate these price feeds to cause a decentralized finance protocol to misprice assets, leading to unfair liquidations, arbitrage opportunities, or the draining of funds. This type of attack undermines the reliability of protocols dependent on accurate external market data. It exploits the trust placed in data providers.
Context
Price feed attacks represent a significant and ongoing security threat to decentralized finance protocols, with numerous incidents reported in crypto news. The discussion centers on strengthening oracle security, including implementing decentralized oracle networks, using multiple data sources, and incorporating time-weighted average prices. A critical future development involves developing more robust and resilient oracle solutions that are resistant to manipulation and censorship.
