During an engagement, a penetration tester needs to break the key for the Wi-Fi network that uses WPA2 encryption. Which of the following attacks would accomplish this objective?
- A. KRACK
- B. Initialization vector
- C. ChopChop
- D. Replay
Answer: A
Explanation:
To break the key for a Wi-Fi network that uses WPA2 encryption, the penetration tester should use the KRACK (Key Reinstallation Attack) attack.
* KRACK (Key Reinstallation Attack):
* Definition: KRACK is a vulnerability in the WPA2 protocol that allows attackers to decrypt and potentially inject packets into a Wi-Fi network by manipulating and replaying cryptographic handshake messages.
* Impact: This attack exploits flaws in the WPA2 handshake process, allowing an attacker to break the encryption and gain access to the network.
* Other Attacks:
* ChopChop: Targets WEP encryption, not WPA2.
* Replay: Involves capturing and replaying packets to create effects such as duplicating transactions; it does not break WPA2 encryption.
* Initialization Vector (IV): Related to weaknesses in WEP, not WPA2.
Pentest References:
* Wireless Security: Understanding vulnerabilities in Wi-Fi encryption protocols, such as WPA2, and how they can be exploited.
* KRACK Attack: A significant vulnerability in WPA2 that requires specific techniques to exploit.
By using the KRACK attack, the penetration tester can break WPA2 encryption and gain unauthorized access to the Wi-Fi network.

- A. Encrypting the passwords with a stronger algorithm
- B. Setting the minimum password length to ten characters
- C. Implementing a blocklist of known bad passwords
- D. Requiring passwords to follow complexity rules
Answer: C
Explanation:
The penetration tester's discovery of passwords vulnerable to hash cracking suggests a lack of robust password policies within the organization. Among the options provided, implementing a blocklist of known bad passwords is the most effective immediate remediation. This measure would prevent users from setting passwords that are easily guessable or commonly used, which are susceptible to hash cracking tools like Hashcat.
Requiring passwords to follow complexity rules (Option A) can be helpful, but attackers can still crack complex passwords if they are common or have been exposed in previous breaches. Setting a minimum password length (Option C) is a good practice, but length alone does not ensure a password's strength against hash cracking techniques. Encrypting passwords with a stronger algorithm (Option D) is a valid long-term strategy but would not prevent users from choosing weak passwords that could be easily guessed before hash cracking is even necessary.
Therefore, a blocklist addresses the specific vulnerability exposed by the penetration tester-users setting weak passwords that can be easily cracked. It's also worth noting that the best practice is a combination of strong, enforced password policies, user education, and the use of multi-factor authentication to enhance security further.

NEW QUESTION # 91
A penetration tester needs to confirm the version number of a client's web application server. Which of the following techniques should the penetration tester use?
- A. Banner grabbing
- B. Directory brute forcing
- C. SSL certificate inspection
- D. URL spidering
Answer: A
Explanation:
Banner grabbing is a technique used to gather information about a service running on an open port, which often includes the version number of the application or server. Here's why banner grabbing is the correct answer:
* Banner Grabbing: It involves connecting to a service and reading the welcome banner or response, which typically includes version information. This is a direct method to identify the version number of a web application server.
* SSL Certificate Inspection: While it can provide information about the server, it is not reliable for identifying specific application versions.
* URL Spidering: This is used for discovering URLs and resources within a web application, not for version identification.
* Directory Brute Forcing: This is used to discover hidden directories and files, not for identifying version information.
References from Pentest:
* Luke HTB: Shows how banner grabbing can be used to identify the versions of services running on a server.
* Writeup HTB: Demonstrates the importance of gathering version information through techniques like banner grabbing during enumeration phases.
Conclusion:
Option C, banner grabbing, is the most appropriate technique for confirming the version number of a web application server.
