Oracle manipulation remains one of the highest-impact attack vectors in decentralized finance. When an oracle reports false prices, the damage propagates through every protocol that depends on those prices for collateral valuation, liquidation thresholds, and yield calculations. This article examines how low-liquidity pools enable price manipulation, why external dependencies create systemic risk, and how time-weighted average price models serve as a critical defense mechanism against flash loan attacks and coordinated price movements. How Oracles Become Attack Surfaces An oracle is fundamentally a mechanism that brings off-chain data into a blockchain environment where smart contracts can read it. The oracle problem itself is not new: how do you ensure that data reported to an immutable ledger has not been tampered with, delayed, or misrepresented by the entity reporting it?…
