We get a zip file named flag.zip from the link, unzip needs a passcode so a quick fcrackzip with the rockyou.txt wordlist

`fcrackzip -v -D -u -p /usr/share/wordlists/rockyou.txt flag.zip`

`PASSWORD FOUND!!!!: pw == !!!0mc3t`

unzips to give the file flag.txt file which has a hex encoded string in side.

`652076206c207a207b207320302075206e2064205f20302066205f206d2075203520692063207d206320742066`

decoding that we get the flag
