Van Hauser and Ronald Kessler are the authors of Hydra. It is under the AGPL As you read, Hydra is parallelized and this feature is the reason for the speed of this password cracker tool. Depend on the protocol it could be very fast. Researchers and security teams use Hydra to observe how they can protect themselves against the attacks. In the following, you will learn more about Hydra.
Hydra is available in both command and graphical format. Hydra is pre-installed on Kali Linux and you will already have a version of Hydra installed. But if you wish to use other Debian based Linux Operating Systems, download from the repository by running the following command:.

Things might not work! If you want the ssh module, you have to setup libssh not libssh2! For all other Linux derivates and BSD based systems, use the system software installer and look for similarly named libraries like in the command above. In all other cases, you have to download all source libraries and compile them manually.
If you just enter hydra , you will see a short summary of the important options available. Generate them yourself. Via the command line options you specify which logins to try, which passwords, if SSL should be used, how many parallel tasks to use for attacking, etc. FIRST — select your target you have three options on how to specify the target you want to attack:.
