Exploring Flash Loan Vulnerabilities: Crafting Unique Exploits from Scratch
<p>In this article, our focus shifts to comprehending a flash loan attack through the process of independently re-crafting its Proof of Concept (PoC) test case, employing the Foundry project [1]. We strongly advise perusing the preceding article before delving into the technical intricacies outlined here.</p>

<p>We are trying to re-write the test case for <a href="https://github.com/SunWeb3Sec/DeFiHackLabs#20230512-lw---flashloan-price-manipulation" rel="noopener ugc nofollow" target="_blank">LW — FlashLoan Price Manipulation</a> attack without looking into the source code.</p>
<h2>Step 1: Structure</h2>
<p>In the DeFiHackLabs repository, create a new file under the name <strong>myexp </strong>(<code>src/test/myexp.sol</code>). Proceed by outlining the attack template’s structure within this newly created file.</p>
