## Solution


For this challenge we get an image of `Margaret Hamilton`. We can use `binwalk` to check if some files are embedded.

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

DECIMAL HEXADECIMAL DESCRIPTION
--------------------------------------------------------------------------------
0 0x0 JPEG image data, JFIF standard 1.01
98309 0x18005 Zip archive data, at least v2.0 to extract, compressed size: 923047, uncompressed size: 932086, name: margaret_flag.png
1021518 0xF964E End of Zip archive, footer length: 22
```

Another image was extracted. Opening the image gives the flag:

Flag `chctf{i_wr1t3_code_by_h4nd}`
