In the context of the Nmap command nmap -sV -sC 10.10.119.162, -sV and -sC are options that modify the scan’s behavior:
-
-sV(Version Detection): This option tells Nmap to perform version detection on the open ports it finds. Instead of just reporting that a port is open, Nmap will attempt to identify the specific service and version number running on that port. This is crucial for identifying specific vulnerabilities, as different versions of a service often have different weaknesses. -
-sC(Script Scanning): This option tells Nmap to run its default set of scripts against the target. Nmap includes a large number of scripts (the NSE – Nmap Scripting Engine) that perform various tasks, including:- Vulnerability detection: Checking for known vulnerabilities in services running on the target.
- Service and OS fingerprinting: Gathering more detailed information about the services and operating system.
- Network and system information gathering: Collecting data such as the target’s network configuration.
By combining -sV and -sC, the Nmap scan provides more comprehensive information about the target, including the versions of running services and the results of default script scans, increasing the chances of identifying exploitable vulnerabilities. It’s a good starting point for reconnaissance before attempting an exploit like EternalBlue.
