Really Secure Apparently

Apparently this encryption is "really secure" and I don't need to worry about sharing the ciphertext, or even these values..

About the Challenge

We were given a n, e, and also a file called ciphertext (You can download the file [here])

How to Solve?

We can decrypt the ciphertext using the Wiener attack because the e value is so large. In this case, I'm using this website and then inputting the values of n, e, and c
