This challenge supplied an `evlz.pdf` PDF file, which was password protected.

I used [`pdfcrack`](https://github.com/robins/pdfcrack) to crack the password with `rockyou.txt`, the common dictionary/password list.

pdfcrack --wordlist=rockyou.txt evlz.pdf

It got the password as `*yellowtulip*`. I entered that as the password to open the PDF, and it worked! The PDF was empty other than just the flag text: __`evlz{always_use_password_managers}ctf`__
