After downloading a picture of a beautiful butterfly, we need to find the flag inside the picture. The file is available [here](https://raw.githubusercontent.com/d0tslashpwn/ctf-files/master/Sunshine-CTF-2016/forensics/butterfly-effect/butterfly.png). We use the application [Steganabara](https://www.wechall.net/downloads/by/user_name/ASC/page-1).

```
% java -jar steganabara-1.1.1.jar
```

We modify a bit the color as shown below.

We finally find the flag; `sun{READY_THE_4CID_M4GNET!}`.
