NMAP is a network probe and discovery application.
This means disabling any default accounts that might be built into network devices and making sure that any SSH ports that are not needed are closed. Using SSH is a much better bet, but you need to keep your login credentials safe to prevent unauthorized access. This means that you need to use encrypted SSH sessions whenever possible if you are going to avoid giving away important login details for sensitive appliances and devices. The data that is passed through Telnet is in plaintext, as we discussed in our article link above.

Once connected to a system via SSH or Telnet, the attacker can begin performing actions that compromise the system, or interconnected series of systems such as a LAN or WAN. By leveraging the information that is gathered through packet sniffing, shoulder-surfing or dumpster-diving, an attacker could potentially find out just enough information to connect to a system without gaining authorization to do so. PuTTY is not malicious in its own right, as it is merely a conduit for attackers to pass their commands through. IT allows users to remotely log in and administer devices such as hardware appliances and applications that host SSH or Telnet sessions. PuTTY is a versatile SSH and Telnet client that can be downloaded for most operating systems. POST data is usually generated when a login request is sent to a web page, so if you have any unsecured web applications on your network, then this data can be captured with Wireshark. If the attacker had to do a simple packet capture in the hopes of capturing http traffic that is unencrypted, this could easily be done by filtering POST data. Encryption is important, as it hides identifiable information that the user is entering.
This is not always easy because in order to sniff traffic, the attacker usually needs to have physical access to the network.Īssuming the person performing the attack is present within the network, there is a lot of information that can be discerned from analyzing packets. Perhaps one of the most publicized hacking activities that are performed with Wireshark is packet interception. In fact, we looked at how we can find login details for Telnet by using Wireshark in this article here. Wireshark is the default packet analyzer for many network professionals, so it should come as no surprise that this powerful freeware tool can also be used for malicious purposes. Most Intrusion Detection/Prevention Systems (NIDS/NIPS) are able to find network scanning activity when it is present on the network, so if it is an unsanctioned activity, it can be quickly identified and stopped.Ī copy of Angry IP Scanner can be downloaded here.

Angry IP Scanner can also find fetchers that relate to each target machine such as TTL, open ports, filtered ports, web detect, HTTP sender, comments, NetBIOS information, MAC address, MAC vendor and even packet loss. Angry IP Scanner is able to identify targets so that other tools can be used to further the attack. Mapping the network and the devices that are present is one of the quickest and easiest ways to find potential targets. The most obvious one is reconnaissance work by a potential attacker. However, these same features can also be used for malicious purposes. This is very useful with the many different IoT devices that use ethernet and Wi-Fi to connect to modern networks.
This is especially helpful where there are newly configured devices that haven’t yet been documented, or as a troubleshooting step when trying to diagnose connectivity issues.Īngry IP Scanner is able to scan multiple broadcast domains and find out network host information such as the network name, IP address and MAC address. IP scanners are legitimate tools that can help users to discover devices they weren’t aware of on the network.
