A Certified Ethical Hacker is attempting to gather information about a target organization's network structure through network footprinting. During the operation, they encounter ICMP blocking by the target system's firewall. The hacker wants to ascertain the path that packets take to the host system from a source, using an alternative protocol. Which of the following actions should the hacker consider next?

  • A. Use UDP Traceroute in the Linux operating system by executing the 'traceroute' command with the destination IP or domain name.
  • B. Use the ICMP Traceroute on the Windows operating system as it is the default utility.

Selected Answer: A
The traceroute utility in Linux, by default, sends UDP packets to high-numbered ports (starting at 33434) and listens for ICMP "port unreachable" messages from the destination. This method can bypass ICMP blocking since it doesn't rely on ICMP echo requests for its operation. By executing traceroute [destination IP/domain], you can trace the route packets take to the target system.

Selected Answer: A
A. Use UDP Traceroute in the Linux operating system by executing the 'traceroute' command with the destination IP or domain name. When ICMP is blocked by a firewall, you can use alternative protocols like UDP for tracerouting. In Linux, the 'traceroute' command allows you to specify the UDP protocol using the '-U' option.
