Cybersecurity analysts will learn how to modify scripts for reconnaissance and enumeration purposes. They will also understand which tools to use for these stages, essential for gathering crucial information before performing deeper penetration tests.
主題 2
  • Attacks and Exploits: This extensive topic trains cybersecurity analysts to analyze data and prioritize attacks. Analysts will learn how to conduct network, authentication, host-based, web application, cloud, wireless, and social engineering attacks using appropriate tools. Understanding specialized systems and automating attacks with scripting will also be emphasized.
主題 3
  • Engagement Management: In this topic, cybersecurity analysts learn about pre-engagement activities, collaboration, and communication in a penetration testing environment. The topic covers testing frameworks, methodologies, and penetration test reports. It also explains how to analyze findings and recommend remediation effectively within reports, crucial for real-world testing scenarios.
主題 4
  • Vulnerability Discovery and Analysis: In this section, cybersecurity analysts will learn various techniques to discover vulnerabilities. Analysts will also analyze data from reconnaissance, scanning, and enumeration phases to identify threats. Additionally, it covers physical security concepts, enabling analysts to understand security gaps beyond just the digital landscape.
主題 5
  • Post-exploitation and Lateral Movement: Cybersecurity analysts will gain skills in establishing and maintaining persistence within a system. This topic also covers lateral movement within an environment and introduces concepts of staging and exfiltration. Lastly, it highlights cleanup and restoration activities, ensuring analysts understand the post-exploitation phase’s responsibilities.

最新的 CompTIA PenTest+ PT0-003 免費考試真題 (Q109-Q114):

問題 #109
During an engagement, a penetration tester discovers a web application vulnerability that affects multiple devices. The tester creates and runs the following script:
#!/bin/sh
for addr in $(cat targets)
do
curl
http://$addr//atod.php?execf=echo%20%22ssh-ed25519%20AAAC3NzaC1lZDI1NTE5AAAA...%22%20%
3E%3E%20/root/authorized_users
done
Which of the following best describes what the tester is attempting to do?

答案：D

解題說明：
The script iterates through a list of target hosts and sends an HTTP request to a vulnerable endpoint (atod.php) with a parameter (execf=) that appears to trigger remote command execution on each device. The command being issued is echo " ssh-ed25519 ... " followed by an append redirection operator ( > > ) into a file under
/root/authorized_users. The ssh-ed25519 string is the format of an SSH public key, and appending a public key into an "authorized users/keys" style file is a common persistence technique that allows the tester (or an attacker) to authenticate via SSH without knowing a password.
In PenTest+ terms, this is establishing persistence/backdoor access after exploitation by planting an authentication mechanism that can be reused later. It is not creating a bind shell (no listener is set up), not changing a root password (no passwd or hash modification is shown), and not generating keys for decryption (the key material is being written to an authorization file for access). The loop indicates the intent is to apply this across multiple affected devices.


問題 #110
A penetration tester cannot find information on the target company's systems using common OSINT methods. The tester's attempts to do reconnaissance against internet-facing resources have been blocked by the company's WAF. Which of the following is the best way to avoid the WAF and gather information about the target company's systems?

答案：C

解題說明：
When traditional reconnaissance methods are blocked, scanning code repositories is an effective method to gather information. Here's why:
Code Repository Scanning:
Leaked Information: Code repositories (e.g., GitHub, GitLab) often contain sensitive information, including API keys, configuration files, and even credentials that developers might inadvertently commit.
Accessible: These repositories can often be accessed publicly, bypassing traditional defenses like WAFs.
Comparison with Other Methods:
HTML Scraping: Limited to the data present on web pages and can still be blocked by WAF.
Directory Enumeration: Likely to be blocked by WAF as well and might not yield significant internal information.
Port Scanning: Also likely to be blocked or trigger alerts on WAF or IDS/IPS systems.
Scanning code repositories allows gathering a wide range of information that can be critical for further penetration testing effort


問題 #111
Given the following Nmap scan command:
[root@kali ~]# nmap 192.168.0 .* -- exclude 192.168.0.101

Which of the following is the total number of servers that Nmap will attempt to scan?

答案：A

解題說明：
The Nmap scan command given will scan all the hosts in the 192.168.0.0/24 subnet, except for the one with the IP address 192.168.0.101. The subnet has 256 possible hosts, but one of them is excluded, so the total number of servers that Nmap will attempt to scan is 255. References:
Nmap Commands - 17 Basic Commands for Linux Network, Section: Scan Multiple Hosts, Subsection: Excluding Hosts from Search Nmap Cheat Sheet 2023: All the Commands and More, Section: Target Specification, Subsection:
-exclude


問題 #112
During an assessment, a penetration tester found a suspicious script that could indicate a prior compromise.
While reading the script, the penetration tester noticed the following lines of code:

Which of the following was the script author trying to do?

答案：A

解題說明：
The script author was trying to spawn a local shell by using the os.system() function, which executes a command in a subshell. The command being executed is "/bin/bash", which is the path to the bash shell, a common shell program on Linux systems. The script author may have wanted to spawn a local shell to gain more control or access over the compromised system, or to execute other commands that are not possible in the original shell. The other options are not plausible explanations for what the script author was trying to do.


問題 #113
SIMULATION
A penetration tester performs several Nmap scans against the web application for a client.
INSTRUCTIONS
Click on the WAF and servers to review the results of the Nmap scans. Then click on each tab to select the appropriate vulnerability and remediation options.
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.




答案：

解題說明：
See the explanation part for detailed solution
Explanation:


Most likely vulnerability: Perform a SSRF attack against App01.example.com from CDN.example.com.
Two best remediation options:
Restrict direct communications to App01.example.com to only approved components.
Require an additional authentication header value between CDN.example.com and App01.example.com.
Restrict direct communications to App01.example.com to only approved components: This limits the exposure of the application server by ensuring that only specified, trusted entities can communicate with it.
Require an additional authentication header value between CDN.example.com and App01.example.com: Adding an authentication layer between the CDN and the app server helps ensure that requests are legitimate and originate from trusted sources, mitigating SSRF and other indirect attack vectors.
Nmap Scan Observations:
CDN/WAF shows open ports for HTTP and HTTPS but filtered for MySQL, indicating it acts as a filtering layer.
App Server has open ports for HTTP, HTTPS, and filtered for MySQL.
DB Server has all ports filtered, typical for a database server that should not be directly accessible.
These findings align with the SSRF vulnerability and the appropriate remediation steps to enhance the security of internal communications.
