## Solution

* Running `strings` on the image we see there is a `margaret_flag.png` after the IEND chunk.
* Using `binwalk` we can extract the file.

```
$ binwalk -e Apollo-Mystery.jpg
```

* We get a png file with the flag at the bottom of the image. ![flag](https://1613628666-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FKkuxWaWwvkRd57ql1rtY%2Fuploads%2Fgit-blob-6c2bfef51c5c5f283b1a66b288a7881c948a7246%2Fflag.png?alt=media)
