##### Solution:

You are given a zip file with 5 images. Because the desciption says find a location and you are given images the best place to start is the exif data because it can contain location information. If you look at the exif data of the images using exiftool you will notice that there is GPS Positions in every image and also Creator notes.

```
┌──(kali㉿kali)-[~/CTFs/TexSAW2024/Lightning]
└─$ exiftool * | grep "Position"
GPS Position : 29 deg 11' 6.00" N, 81 deg 4' 13.00" W
GPS Position : 34 deg 54' 9.00" N, 110 deg 10' 7.00" W
GPS Position : 35 deg 22' 23.00" N, 138 deg 55' 36.00" E
GPS Position : 43 deg 21' 45.00" N, 71 deg 27' 38.00" W
GPS Position : 45 deg 37' 2.00" N, 9 deg 16' 53.00" E

└─$ exiftool * | grep "Creator"
Creator : Three Words
Creator : Two Words
Creator : Two Words
Creator : 4 Words
Creator : 1 Words

└─$ ls
alldiesel.jpg champ.jpg piston.jpg queen.jpg supercar.jpg

```

When you put the coordinates into google maps you get the following locations(if you are trying this yourself just copy and paste the coordinates and make sure to use the degree symbol):

| Image Names: | Coordinates(from exif data(change deg ->°)): | Location name: |
| -------- | -------- | -------- |
| alldiesel.jpg | 29°11' 6.00" N, 81°4' 13.00" W | Daytona International Speedway |
| champ.jpg | 34°54' 9.00" N, 110°10' 7.00" W | Wigwam - > Wigwam Motel |
| piston.jpg | 35°22' 23.00" N, 138°55' 36.00" E | Fuji Speedway |
| queen.jpg | 43°21' 45.00" N, 71°27' 38.00" W | New Hampshire Motor Speedway |
| supercar.jpg | 45°37' 2.00" N, 9°16' 53.00" E | Autodromo Nazionale Monza - > Monza |

The creator notes tell you how many words should be in each of the names. All of these match except "Wigwam" and the "Autodromo Nazionale Monza" have the correct number of words. "Wigwam" is the "Wigwam Motel" and "Autodromo Nazionale Monza" is just "Monza". The order to these is also important. The images can all be combined into one, a bit like a basic puzzle, when it is complete it shows an image of lightning mcqueen. The order of the image was "alldiesel.jpg" then "supercar.jpg" then "piston.jpg" then "queen.jpg" then "champ.jpg". Then you put the place from those images in that order. So it would go Daytona International Speedway then Monza etc.. You also then make everything lowercase, remove all the spacing, and add the texsaw{} to get a long flag(as said in the instructions).

The final flag is: `texsaw{daytonainternationalspeedwaymonzafujispeedwaynewhampshiremotorspeedwaywigwammotel}`
