A penetration tester completes a scan and sees the following output on a host:bashCopy codeNmap...

The ms17_010_eternalblue exploit is the most appropriate choice based on the scenario.

Why MS17-010 EternalBlue?

EternalBlue is a critical vulnerability in SMBv1 (port 445) affecting older versions of Windows, including Windows 7.

The exploit can be used to execute arbitrary code remotely, providing shell access to the target system.

Other Options:

A (psexec): This exploit is a post-exploitation tool that requires valid credentials to execute commands remotely.

B (ms08_067_netapi): A vulnerability targeting older Windows systems (e.g., Windows XP). It is unlikely to work on Windows 7.

D (snmp_login): This is an auxiliary module for enumerating SNMP, not gaining shell access.
