Once there I simply grabbed the users.txt file that contained the following users:

# username:password
alice:BYNdCesZqW
bob:jw2ueICLvT
charlie:G5vCxkVV3m
natas3:sJIJNW6ucpu6HPZ1ZAchaDtwd7oGrD14
eve:zo4mJWyNj2
mallory:9urtcpzBmH

We are obviously looking for the password to natas3: sJIJNW6ucpu6HPZ1ZAchaDtwd7oGrD14
