Options of Hydra Supported protocols

cisco

Module cisco is optionally taking the keyword ENTER, it then sends an initial ENTER when connecting to the service.

cisco-enable

Module cisco-enable is optionally taking the logon password for the cisco device

Note: if AAA authentication is used, use the -l option for the username and the optional parameter for the password of the user.

Examples:

123hydra -P pass.txt target cisco-enable  (direct console access)hydra -P pass.txt -m cisco target cisco-enable  (Logon password cisco)hydra -l foo -m bar -P pass.txt target cisco-enable  (AAA Login foo, password bar)

cvs

Module cvs is optionally taking the repository name to attack, default is "/root"

firebird

Module firebird is optionally taking the database path to attack, default is "C:\Program Files\Firebird\Firebird_1_5\security.fdb"

http-get, https-get, http-post, https-post

Module http-get requires the page to authenticate.

For example:  "/secret" or "http://bla.com/foo/bar" or "https://test.com:8080/members"

http-get-form, https-get-form, http-post-form, https-post-form

Module http-get-form requires the page and the parameters for the web form.

By default this module is configured to follow a maximum of 5 redirections in a row. It always gathers a new cookie from the same URL without variables The parameters take three ":" separated values, plus optional values. 

(Note: if you need a colon in the option string as value, escape it with "\:", but do not escape a "\" with "\\".)

Syntax:  

1<url>:<form parameters>:<condition string>[:<optional>[:<optional>]</optional></optional>
  • First is the page on the server to GET or POST to (URL).
  • Second is the POST/GET variables (taken from either the browser, proxy, etc. with usernames and passwords being replaced in the "^USER^" and "^PASS^" placeholders (FORM PARAMETERS)
  • Third is the string that it checks for an *invalid* login (by default). Invalid condition login check can be preceded by "F=", successful condition login check must be preceded by "S=". This is where most people get it wrong. You have to check the webapp what a failed string looks like and put it in this parameter!

The following parameters are optional:

C=/page/uri    

to define a different page to gather initial cookies from

(h|H)=My-Hdr\: foo  

to send a user defined HTTP header with each request

^USER^ and ^PASS^ can also be put into these headers!

Note: 'h' will add the user-defined header at the end regardless it's already being sent by Hydra or not. 

'H' will replace the value of that header if it exists, by the one supplied by the user, or add the header at the end.

Note that if you are going to put colons (:) in your headers you should escape them with a backslash (\). All colons that are not option separators should be escaped (see the examples above and below).

You can specify a header without escaping the colons, but that way you will not be able to put colons in the header value itself, as they will be interpreted by hydra as option separators.

Examples:

12345"/login.php:user=^USER^&pass=^PASS^:incorrect""/login.php:user=^USER^&pass=^PASS^&colon=colon\:escape:S=authlog=.*success""/login.php:user=^USER^&pass=^PASS^&mid=123:authlog=.*failed""/:user=^USER&pass=^PASS^:failed:H=Authorization\: Basic dT1w:H=Cookie\: sessid=aaaa:h=X-User\: ^USER^""/exchweb/bin/auth/owaauth.dll:destination=http%3A%2F%2F<target>%2Fexchange&flags=0&username=<domain>%5C^USER^&password=^PASS^&SubmitCreds=x&trusted=0:reason=:C=/exchweb"

http-proxy

Module http-proxy is optionally taking the page to authenticate at.

Default is http://www.microsoft.com/)

Basic, DIGEST-MD5 and NTLM are supported and negotiated automatically.

http-proxy-urlenum

Module http-proxy-urlenum only uses the -L option, not -x or -p/-P option. The -L loginfile must contain the URL list to try through the proxy. The proxy credentials cann be put as the optional parameter, e.g.

12hydra -L urllist.txt -s 3128 target.com http-proxy-urlenum user:passhydra -L urllist.txt http-proxy-urlenum://target.com:3128/user:pass

imap, imaps

Module imap is optionally taking one authentication type of: CLEAR or APOP (default), LOGIN, PLAIN, CRAM-MD5, CRAM-SHA1, CRAM-SHA256, DIGEST-MD5, NTLM

Additionally TLS encryption via STARTTLS can be enforced with the TLS option.

Example: imap://target/TLS:PLAIN

irc

Module irc is optionally taking the general server password, if the server is requiring one and none is passed the password from -p/-P will be used

ldap2, ldap2s, ldap3, ldap3s, ldap3-crammd5, ldap3-crammd5s, ldap3-digestmd5, ldap3-digestmd5s

Module ldap2 is optionally taking the DN (depending of the auth method choosed

Note: you can also specify the DN as login when Simple auth method is used).

The keyword "^USER^" is replaced with the login.

Special notes for Simple method has 3 operation modes: anonymous, (no user no pass), unauthenticated (user but no pass), user/pass authenticated (user and pass).

So don't forget to set empty string as user/pass to test all modes.

Hint: to authenticate to a windows active directy ldap, this is usually cn=^USER^,cn=users,dc=foo,dc=bar,dc=com for domain foo.bar.com

mysql

Module mysql is optionally taking the database to attack, default is "mysql"

nntp

Module nntp is optionally taking one authentication type of: USER (default), LOGIN, PLAIN, CRAM-MD5, DIGEST-MD5, NTLM

oracle-listener

Module oracle-listener / tns is optionally taking the mode the password is stored as, could be PLAIN (default) or CLEAR

pop3, pop3s

Module pop3 is optionally taking one authentication type of: CLEAR (default), LOGIN, PLAIN, CRAM-MD5, CRAM-SHA1, CRAM-SHA256, DIGEST-MD5, NTLM.

Additionally TLS encryption via STLS can be enforced with the TLS option.

Example: pop3://target/TLS:PLAIN

postgres

Module postgres is optionally taking the database to attack, default is "template1"

rdp

Module rdp is optionally taking the windows domain name.

For example:

1hydra rdp://192.168.0.1/firstdomainname -l john -p doe

s7-300

Module S7-300 is for a special Siemens PLC. It either requires only a password or no authentication, so just use the -p or -P option.

smb

Module smb default value is set to test both local and domain account, using a simple password with NTLM dialect.

Note: you can set the group type using LOCAL or DOMAIN keyword or other_domain:{value} to specify a trusted domain.

You can set the password type using HASH or MACHINE keyword (to use the Machine's NetBIOS name as the password).

You can set the dialect using NTLMV2, NTLM, LMV2, LM keyword.

Example: 

123hydra smb://microsoft.com  -l admin -p tooeasy -m "local lmv2"hydra smb://microsoft.com  -l admin -p D5731CFC6C2A069C21FD0D49CAEBC9EA:2126EE7712D37E265FD63F2C84D2B13D::: -m "local hash"hydra smb://microsoft.com  -l admin -p tooeasy -m "other_domain:SECONDDOMAIN"

smtp, smtps

Module smtp is optionally taking one authentication type of: LOGIN (default), PLAIN, CRAM-MD5, DIGEST-MD5, NTLM

12345678910111213READ  perform read requests (default)WRITE perform write requests1     use SNMP version 1 (default)2     use SNMP version 23     use SNMP version 3Note that SNMP version 3 usually uses both login and passwords!SNMP version 3 has the following optional sub parameters:MD5   use MD5 authentication (default)SHA   use SHA authenticationDES   use DES encryptionAES   use AES encryptionif no -p/-P parameter is given, SNMPv3 noauth is performed, whichonly requires a password (or username) not both.

To combine the options, use colons (":"), e.g.:

12hydra -L user.txt -P pass.txt -m 3:SHA:AES:READ target.com snmphydra -P pass.txt -m 2 target.com snmp

sshkey

Module sshkey does not provide additional options, although the semantic for options -p and -P is changed:

  • -p expects a path to an unencrypted private key in PEM format.
  • -P expects a filename containing a list of path to some unencrypted private keys in PEM format.

svn

Module svn is optionally taking the repository name to attack, default is "trunk"

Tools included in the hydra package

  • hydra – Very fast network logon cracker
  • pw-inspector – Reads passwords in and prints those which meet the requirements

Help pw-inspector

PW-Inspector reads passwords in and prints those which meet the requirements. The return code is the number of valid passwords found, 0 if none was found. Use for security: check passwords, if 0 is returned, reject password choice. 

Use for hacking: trim your dictionary file to the pw requirements of the target.
