Actual exam question from ECCouncil's 312-50v12
Question #: 59
Topic #: 1
[All 312-50v12 Questions]

Jim, a professional hacker, targeted an organization that is operating critical industrial infrastructure. Jim used Nmap to scan open ports and running services on systems connected to the organization’s OT network. He used an Nmap command to identify Ethernet/IP devices connected to the Internet and further gathered information such as the vendor name, product code and name, device name, and IP address.
Which of the following Nmap commands helped Jim retrieve the required information?

  • A. nmap -Pn -sT --scan-delay 1s --max-parallelism 1 -p < Port List > < Target IP >
  • B. nmap -Pn -sU -p 44818 --script enip-info < Target IP >
  • C. nmap -Pn -sT -p 46824 < Target IP >
  • D. nmap -Pn -sT -p 102 --script s7-info < Target IP >

Selected Answer: B
B. nmap -Pn -sU -p 44818 --script enip-info < Target IP > Explanation: The Ethernet/IP protocol is commonly used in industrial control systems (ICS) and critical infrastructure. Jim targeted an organization that is operating critical industrial infrastructure, and he used Nmap to scan open ports and running services on systems connected to the organization's OT network. To identify Ethernet/IP devices connected to the Internet and gather information such as the vendor name, product code and name, device name, and IP address, Jim used the Nmap script "enip-info". This script is designed to scan for Ethernet/IP devices and gather information about them.

The port 44818 should be the TCP (explicit) and port 2222 is the UDP (implicit). I'm curious why the answer is "B. nmap -Pn -sU -p 44818 --script enip-info < Target IP >`", but not "B. nmap -Pn -sT -p 44818 --script enip-info < Target IP >`"?

This is probably because the option "-sU" specifies just an UDP scan for open port, but the option "--script enip-info" specifies to also scan for TCP port 44818. See the nmap documentation: https://nmap.org/nsedoc/scripts/enip-info.html This NSE script is used to send a EtherNet/IP packet to a remote device that has TCP 44818 open. The script will send a Request Identity Packet and once a response is received, it validates that it was a proper response to the command that was sent, and then will parse out the data. Information that is parsed includes Device Type, Vendor ID, Product name, Serial Number, Product code, Revision Number, status, state, as well as the Device IP.

He wants to identify Ethernet/IP devices, therefore he can use --script enip-info. And this script uses TCP 44818.

Scanning Ethernet/IP Devices (OT) nmap -Pn -sU -p 44818 --script enip-info <Target IP> Ethernet/IP is a popular protocol implemented by many industrial networks. Ethernet/IP uses Ethernet as a transport layer protocol, and CIP is used to provide services for industrial applications. This protocol operates on UDP port number 44818. Using the above command, attackers can gather information such as the name of the vendor, product code and name, device name, IP address, etc. CEH V12 page 2981
