## Latency-Based Oracle Attacks

Latency-based oracle attacks occur when an adversary exploits the time delay between when a price change happens on a reference exchange and when that price is updated on a decentralized finance protocol. Because many protocols rely on external price feeds or oracles to trigger liquidations or determine collateral value, a malicious actor can observe a price movement on a fast exchange and execute a transaction on the protocol before the oracle updates.

By manipulating this window of opportunity, the attacker can liquidate undercollateralized positions or trade against stale prices for profit. This vulnerability stems from the fundamental challenge of synchronizing off-chain market data with on-chain smart contract execution.

These attacks are particularly prevalent in decentralized derivatives markets where speed is critical for maintaining solvency. The gap between real-world market reality and on-chain state creates a race condition that sophisticated traders exploit to drain liquidity.

Effective mitigation requires minimizing latency or implementing robust deviation thresholds within the oracle mechanism.
