![]() ![]() So, we will test 9 combinations of names and passwords. Both files contain only the three words listed below.

In order to see details of running sign-in attempts, we can check the “Be verbose” and “Show attempts” checkboxes. We also define the SSH protocol and port 22 that corresponds to this protocol. If you want to attack multiple devices at a time, you need to enter a list in the “Target List”. Set the destination IP address in the “Single Target” field. Run it in the following way from the command line. Here’s how to set up this tool to get SSH access. ![]() This method can be implemented, for example, using Hydra, which is available for free at KALI linux. If an attacker wanted to gain access to the devices inside your network, he would have to get access into your network first. The requirement is the availability of the device on the network layer, so potentially all the devices that are available from the Internet. How to hack password with a dictionary attack In the ARP SPOOF ATTACK article, I describe how to do this. If you know who the admin is and he uses non-encrypted protocols for device management, TELNET, or HTTP, it is possible to capture his password using man in the middle attack. ![]() We may do a password recovery, but we probably will not get the device configuration. This method is rather difficult and has its limitations. There are several ways to access the device. Here’s how to hack password and username of network devices with dictionary attack. How do hackers know how to take control of your device, even if they are thousands of miles away? If you are careless and expose your devices to this threat, you may be sure that someone will try to do that.
