Discuss CompTIA PT0-003 Exam Topic 2 Question 39

A penetration tester is enumerating a Linux system. The goal is to modify the following script to provide more comprehensive system information:

#!/bin/bash

ps aux >> linux_enum.txt

Which of the following lines would provide the most comprehensive enumeration of the system?

Acat /etc/passwd >> linux_enum.txt; netstat -tuln >> linux_enum.txt; cat /etc/bash.bashrc >> linux_enum.txt

Bwhoami >> linux_enum.txt; uname -a >> linux_enum.txt; ifconfig >> linux_enum.txt

Chostname >> linux_enum.txt; echo $USER >> linux_enum.txt; curl ifconfig.me >> linux_enum.txt

Dlsof -i >> linux_enum.txt; uname -a >> linux_enum.txt; ls /home/ >> linux_enum.txt

Suggested Answer: A

This command gathers:

/etc/passwd -- lists all local user accounts.

netstat -tuln -- lists listening ports and associated services.

/etc/bash.bashrc -- contains environment variables and configurations that could reveal system behaviors or hidden persistence mechanisms.

This provides a much broader and deeper enumeration compared to other options.

Option B is solid too. System info and user context are important.

I prefer option D. It gives process info and home directories.

I think option A is the best. It covers user info and network services.

Surprised that A isn't the obvious choice!

Colette 2 months ago

Wait, why would you use curl for local info?

Melda 2 months ago

D seems solid too, especially with lsof.

I think B is better for system details.

Amos 3 months ago

Option A gives a lot of user and network info.

I recall that uname -a is important for system info, but I’m not sure if it’s enough on its own. I guess I’d lean towards A for the most coverage.

Timmy 3 months ago

I’m a bit confused about the differences between these options. I feel like B has some good commands, but it might not be as comprehensive as A or D.

Sylvia 3 months ago

I think option D might be the best because it includes lsof, which shows open files and network connections. That could be really useful for enumeration.

I remember we practiced something similar in class, but I’m not sure which option gives the most info. Maybe A? It seems to cover a lot of system details.
