## Description

## Attached files
- None

## Summary
This was a beginner challenge, and the solution is found by inspecting the wasm file that is ran on the website.

## Flag

## Detailed solution
When connecting to the website, you are prompted with a screen as below.

Pressing **CTRL+SHIFT+i** brings up the developer console in chrome.

On this screen, selecting the **Sources** tab, we can see there is a file called “index.wasm”.


In this index page, I just did a seach of “CTF” and found the solution towards the bottom.


Flag found is uiuctf{welcome_to_wasm_e3c3bdd1}.

## Another solution
There is likely another solution involving the developer console tab / trying to get that part of wasm to execute so the flag shows up under “hello, world”. This was the simplest solution for me.
