CATS OMG I CAN'T BELIEVE HOW MANY CATS ARE IN THIS IMAGE I NEED TO VISIT CAN YOU FIGURE OUT THE NAME OF THIS CAT HEAVEN?

Answer is the domain of the website for this location. For example, if the answer was ucla, the flag would be lactf{ucla.edu}.


## Find the flag

**In this challenge, we can download a jpeg [file](https://github.com/siunam321/CTF-Writeups/blob/main/LA-CTF-2023/Misc/CATS!/CATS.jpeg):**
```shell
┌[siunam♥earth]-(~/ctf/LA-CTF-2023/Misc/CAT!)-[2023.02.11|12:15:00(HKT)]
└> file CATS.jpeg
CATS.jpeg: JPEG image data, Exif standard: [TIFF image data, big-endian, direntries=12, manufacturer=Apple, model=iPhone SE (2nd generation), orientation=upper-right, xresolution=192, yresolution=200, resolutionunit=2, software=15.5, datetime=2022:06:17 12:52:05, hostcomputer=iPhone SE (2nd generation), GPS-Data], baseline, precision 8, 4032x3024, components 3
```

**Now, we can use `exiftool` to view it's metadata:**
```shell
┌[siunam♥earth]-(~/ctf/LA-CTF-2023/Misc/CAT!)-[2023.02.11|12:15:35(HKT)]
└> exiftool CATS.jpeg

```

As you can see, we have lots of data.

In the `Location` field, we see: ***Lanai Cat Sanctuary***, which is the image's location!

**Let's google that:**


Right off the bat, we see [this website](https://lanaicatsanctuary.org/):


Hence, the flag is:

- **Flag: `lactf{lanaicatsanctuary.org}`**
