Answers

1 D. The information gathering and vulnerability identification phase uses tools to discover systems, services running on those systems, and vulnerabilities that exist on those systems. See Chapter 1.

2 C. Customers should have penetration testers sign a non-disclosure agreement (NDA) before starting the penetration test. See Chapter 2.

3 B, E. Recon-ng and Maltego are examples of OSINT tools used to discover public information about a customer. See Chapter 3.

4 A. You can use the -Pn parameter on Nmap to disable ping operations when performing a port scan. See Chapter 3.

5 A, B. OpenVAS and Nessus are examples of vulnerability scanners that can be used to discover vulnerabilities on a system. See Chapter 4.

6 C. arpspoof is an example of a tool that can be used during a MiTM attack. arpspoof is used to poison the ARP cache of systems so that the attacker can place themselves in the middle of the communication. See Chapter 5.

7 B. Aireplay-ng is a tool used to generate different types of wireless traffic, including a deauthentication packet that is used to instruct clients to disconnect. See Chapter 6.

8 C. Reaver is a command-line tool in Kali Linux that allows you to perform a brute force attack on the WPS pin. See Chapter 6.

9 D. When looking at the URL that is used in the attack, you want to identify what is being injected. Choice D is injecting the cat command from the operating system so it is considered a command injection attack. See Chapter 7.

10 A. The hashdump command is used during post-exploitation to retrieve a list of password hashes that can then be used in other attacks such as password cracking or a pass-the-hash attack. See Chapter 8.

11 C. Nikto is an example of a web application vulnerability scanner. See Chapter 9.

12 D. Hashcat is a command-line tool in Kali Linux that can be used to crack the password hash. See Chapter 9.

13 C. Hydra is a tool used to crack passwords and can be used to crack passwords of a remote system using protocols such as RDP. See Chapter 9.

14 B. You can tell that the script was created in Python because of the comparison operator being used (==). PowerShell and Bash use -eq as the comparison operator. Also notice the use of the print statement (instead of echo) and the fact variables do not use $ in front of them. See Chapter 10.

15 D. If you notice evidence that a system has been hacked into already, you should halt the penetration test and discuss the finding with the stakeholders right away. See Chapter 11.
