Recalling the basics of Metasploit, we are all set to perform our first penetration test with Metasploit. We will test an IP address here and try to find relevant information about the target IP and will try to break deeper into the network as much as we can. We will follow all the required phases of a penetration test here, which we discussed in the earlier part of this chapter.
Considering a black box penetration test on an unknown network, we can assume that we are done with the preinteractions phase. We are going to test a single IP address in the scope of the test, with zero knowledge of the technologies running on the target. We are performing the test with Kali Linux, a popular security-based Linux distribution, which comes with tons of preinstalled security tools.
As discussed earlier, the gathering intelligence phase revolves around gathering as much information as possible, about the target. Active and passive scans, which include port scanning, banner grabbing, and various other scans, depends upon the type of target that is under test. The target under the current scenario is a single IP address. So here, we can skip gathering passive information and can continue with the active information-gathering methodology.
Let's start with the internal footprinting phase, which includes port scanning, banner grabbing, ping scans to check whether the system is live or not, and service detection scans.
To conduct internal footprinting, NMAP proves as one of the finest available tools. Reports generated by NMAP can be easily imported into Metasploit. Metasploit has inbuilt database functionalities, which can be used to perform NMAP scans from within the Metasploit framework console and store the results in the database.
