# Inception

## Challenge Description

> My friend got inspired by Inception movie and sent this strange image. Can you discover what is this image about ?

## Attached files

* [leaff.jpg](https://github.com/HarshJolad/writeups-pvt/blob/master/YCTF%20Mini%202023/inception/leaff.jpg)

## Solution

* Running `strings`, `binwalk`, `exiftool` on `leaff.jpg` gives nothing useful.
* Using `stegseek` to extract data from `leaff.jpg` gives us a `wav` file.
* Opening it in audacity and viewing the spectogram gives us the flag
* To view the spectogram in audacity
* Open the file in audacity and on the left hand side of the screen, click on the dropdown menu and select spectogram. ![audacity](https://1613628666-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FKkuxWaWwvkRd57ql1rtY%2Fuploads%2Fgit-blob-3eae56687413760e30e5de2a34b1466f7554724e%2Fimage.png?alt=media)
