FakeKitten

a simple script to upload whatever on Amazon Prime Photos

¯\(ツ)/¯

why:

Amazon Prime Photos allows you to upload everything as long as it's an image, giving you unlimited storage (I expect them to do facial recognitioning or other unholy things with your images).

so we can leverage this dynamic to upload any file to resemble an image, just by appending the original file at the end of a random image we are generating on the fly.

the images will be saved as a raw image file, .DNG extension, so the site won't touch it trying to re-compress the image to save files

I've tried to upload files and managed to get 3.5GB without issues

usage:

encoding:

./FakeKitten.sh yourfile.pdf encode

you will obtain a file named:

FakeKitten_143442_yourfile.pdf_3a1863591abdce897987971928512865db_random.DNG

where the file name is composed like this:

[constant]\_[image blocksize]\_[originale filename]\_[sha1sum of the original file]\_[decoy image filename]

at this point you can manually upload it on Amazon Prime Photos

decoding:

./FakeKitten.sh FakeKitten_143442_yourfile.pdf_3a1863591abdce897987971928512865db_random.DNG decode

you will obtain your original file:

yourfile.pdf

• file encryption
