**Challenge**
Here's a picture of my favorite vegetable. I hope it doesn't make you cry.

**Solution**
After a lot of experimenting, we find out we can uncover a hidden message from the image using steghide:
```bash$ steghide extract -sf rabbithole.jpgEnter passphrase: <onion>wrote extracted data to "address.txt".```whoo! contents of the file `address.txt` is:
```wsqxiyhn23zdi6ia```
might be an `.onion` link? Opening `http://wsqxiyhn23zdi6ia.onion` with a tor browser (or via https://onion.link/) gives:

We find nothing in the images, but after some hints we find that the chinese characters are [base65536](https://github.com/Parkayun/base65536)
```python# pip install base65536
import base65536
with open('rabbithole_characters.txt','r') as f:    ct = f.readline().rstrip().replace(' ','')
with open('rabbithole_out','wb') as f2:    f2.write(base65536.decode(ct))```
which turns out to be an epub on cell phone hacking. Searching the contents for the flag gives it to us
