Description: I know the flag is in this file! I just cannot open it for some reason...


We're given a text file.

In it the only recognizable string is VimCrypt~03!

This File has been encrypted with Vim!

Since the mode was ~03 (VimCrypt~03), the most secure mode at this point, I didn't find any exploits to cheese the encryption.

So I resulted to good old bruteforce.

I found this github repo with a nice bruteforce script.

Using it with rockyou.txt as the dictionary yields us the flag in seconds.
