![]() In this case, it’s the FTP service (other services are HTTP-get and so on) Finally, specify the service whose port is open.Specify the IP address of the target being attacked, which in this case is the IP address - 192.168.1.1.The -v flag is optional for verbose mode.Specify the password wordlist using the -P flag of the command.However, if that’s not the case, use the -L flag in the command instead, and specify a wordlist consisting of commonly used usernames when the only option is to guess the username. In this case, the username admin is used, one of the default usernames commonly used across servers and network appliances. The -l flag is used for specifying the login user name.Run the Hydra command to brute force the credentials of this FTP server - Hydra -l admin -P password.txt -v -f 192.168.1.1 FTP.In this case, the FTP service (port) is open. After the Nmap scan is complete, note the open ports and services running on the host.Use the Nmap command - Nmap 192.168.1.1, replacing the given IP address with the target’s (FTP server) IP address. Launch the terminal for entering the commands.First, scan the ports of the target network using a port scanner like Masscan, which has better performance and is faster if the target infrastructure is large, or Nmap.Tip: To get an overview of all the commands, options, and flags that can be used with this tool, use the man hydra command to read the man page of Hydra. Often, default passwords change, so it’s a good idea to keep them updated from resources like the SecLists repository. It’s worth noting here that having a good wordlist is a must for successfully brute-forcing the password. Hydra is used to crack FTP server passwords in this tutorial, but one can crack passwords of network routers and various network appliances using a similar process. This is a bad practice, making Hydra very useful in finding such vulnerabilities during pentests. Steps to crack the password with THC HydraĬracking passwords is made much easier with such a large number of network appliances on the internet and across corporate networks being configured with default usernames and passwords or with weak credentials just for the sake of convenience. With the help of suitable wordlists, Hydra can crack the passwords of a wide range of network routers and devices. ![]() ![]() Hydra can be used to brute-force the password of network routers and other services. Pw-inspector - Reads passwords in and prints those that meet requirements.Hydra - The fast network log-on cracker.There are two tools included in the Hydra package. This post will demonstrate the usage of Hydra and which commands need to be used to do this. When it comes to credential brute-force attacks, Hydra is one of the most widely used tools. ![]() These functions make it a handy tool for network penetration testing. THC Hydra is a password-cracking tool that supports a wide range of network protocols like FTP, LDAP, most HTTP methods like GET and POST, databases like MySQL, and much more. ![]()
