Hydra cracked RDP login

1 description

Before using hydra8.1, I couldn't crack windows2003's RDP login password, but later it was verified that it was caused by a lower version, so I upgraded to the latest version of hydra 8.3 to solve the problem.

2 install the latest version of hydra (v8.3) 2.1 Uninstall hydra v8.1

Kali 2.0 has installed hydra software by default, but the software version uses v8.1 version, so when cracking RDP, it often appears that it cannot be cracked or needs to be cracked many times before it will be cracked successfully, so it is suspected that the version is too old, so upgrade to the latest version (hydra v8.3), after upgrading to v8.3 version, the success rate is indeed very high. Final verification is indeed the reason for the low version of the software.

Uninstall the hydrav8.1 version method of the default installation of kali 2.0, using the following command:

Root@kali:/usr#apt-get autoremove hydra

2.2 download the latest version of hydra v8.3

Hydar download address: https://www.thc.org/thc-hydra/

Open the above URL with a browser and download hydra v8.3

2.3 install hydra v8.3

# tar-zxvf hydra-8.3.tar.gz

# cd hydra-8.3

#. / configure

# make & & make install

After installation, run the rdp or ssh cracking command and find that there is no openssl or LIBSSH compilation support, so find a variety of ways to try online, and finally find a solution, that is, install ssl through the apt-get install cmake libssl-dev command.

Root@kali:~/ Desktop / hydra-8.3#. / hydra- l administrator-p lixiong 192.168.1.110 rdp

A problem occurred during the installation process, that is, the libssl-dev could not be found. Later, it was confirmed that it was caused by the software source included in kali, so it was replaced by other domestic Ali software sources of kali, and the installation was successful, as follows:

Root@kali:~/ Desktop / hydra-8.3/libssh-0.4.8/build#apt-get install cmake libssl-dev

Installation failed because there is a problem with the source of kali

Therefore, the software source of kali is changed to Ali's software source, and the installation is successful.

Note: the software source is in the / etc/apt/souce.list file.

After installation, run the rdp cracking command directly, and it is found that it is still unsuccessful. That is because the previous installation failed, so you need to re-use the make clean command, and then reinstall the general.

Make clean

Reinstall command:

# cd hydra-8.3

#. / configure

# make & & make install

Compile

Installation

Successfully cracked
