## DeFi Oracle Manipulation

DeFi oracle manipulation occurs when an attacker influences the price data provided to a decentralized finance protocol to trigger unintended outcomes. Oracles are the bridges that bring real-world price data onto the blockchain.

If a protocol relies on a single exchange for its price feed, an attacker can execute large trades on that exchange to artificially move the price, thereby tricking the protocol's smart contracts. This can be used to drain funds through fraudulent liquidations or by borrowing assets against overvalued collateral.

Preventing this requires using decentralized, multi-source oracle networks that aggregate data from many exchanges to ensure accuracy and resilience. It is a fundamental aspect of smart contract security and risk management in the DeFi ecosystem.

Protocols that fail to implement robust oracle solutions are highly vulnerable to these types of exploits, which have historically resulted in significant losses for liquidity providers and users.
