## What is the Attack of Flash Loan Attack?

A flash loan attack is a type of economic exploit where an attacker borrows a large amount of capital without collateral, manipulates the price of an asset in a decentralized exchange, and repays the loan within the same blockchain transaction. This attack vector leverages the atomic nature of blockchain transactions to execute complex arbitrage or manipulation strategies that would be impossible in traditional finance. The attacker profits from the price discrepancy created during the manipulation phase.

## What is the Mechanism of Flash Loan Attack?

The mechanism relies on a flash loan, which is an uncollateralized loan that must be repaid before the transaction concludes. The attacker uses the borrowed funds to execute a series of actions, such as buying a large amount of an asset on one exchange to inflate its price, then selling it on another exchange at the manipulated price. The entire sequence must occur within a single block, ensuring the loan is repaid before the transaction finalizes.

## What is the Vulnerability of Flash Loan Attack?

The primary vulnerability exploited by flash loan attacks often lies in the reliance of DeFi protocols on single-source price oracles or low-liquidity automated market makers. By manipulating the price feed, the attacker can trigger liquidations or exploit pricing logic in other protocols. Robust protocols mitigate this risk by using time-weighted average prices (TWAPs) or multiple oracle sources to prevent sudden price manipulation.
