CompTIA PT0-002 Based on Real Exam Environment

Email phishing involves sending fraudulent emails that appear legitimate to trick the recipient into providing sensitive information. This question describes a generic phishing attempt, as it targets a broad audience with urgent claims. This relates to CompTIA Pentest+ objectives under social engineering and phishing techniques.

Nmap is widely used for network scanning and enumeration. It identifies open ports, services, and vulnerabilities on a network. This directly relates to CompTIA Pentest+ objectives on scanning and enumeration methodologies.

The socket.gaierror: [Errno -2] Name or service not known is an error that occurs when the socket module cannot resolve the hostname or IP address given as an argument. In this case, the script is using sys.argv[0] as the argument for socket.gethostbyname, which is the name of the script itself, not the target IP address. The target IP address should be the first command-line argument after the script name, which is sys.argv1. Therefore, changing the script to use sys.argv1 as the argument for socket.gethostbyname will fix the error and allow the script to scan the ports of the target IP address. References:
