質問 # 240
John, a professional hacker, performs a network attack on a renowned organization and gains unauthorized access to the target network. He remains in the network without being detected for a long time and obtains sensitive information without sabotaging the organization. Which of the following attack techniques is used by John?
正解：B
解説：
An advanced persistent threat (APT) may be a broad term wont to describe AN attack campaign within which an intruder, or team of intruders, establishes a bootleg, long presence on a network so as to mine sensitive knowledge.
The targets of those assaults, that square measure terribly fastidiously chosen and researched, usually embrace massive enterprises or governmental networks. the implications of such intrusions square measure huge, and include:
Intellectual property thieving (e.g., trade secrets or patents)
Compromised sensitive info (e.g., worker and user personal data)
The sabotaging of essential structure infrastructures (e.g., information deletion) Total website takeovers Executing an APT assault needs additional resources than a regular internet application attack. The perpetrators square measure typically groups of intimate cybercriminals having substantial resource. Some APT attacks square measure government-funded and used as cyber warfare weapons.
APT attacks dissent from ancient internet application threats, in that:
They're considerably additional advanced.
They're not hit and run attacks-once a network is infiltrated, the culprit remains so as to realize the maximum amount info as potential.
They're manually dead (not automated) against a selected mark and indiscriminately launched against an outsized pool of targets.
They typically aim to infiltrate a complete network, as opposition one specific half.
More common attacks, like remote file inclusion (RFI), SQL injection and cross-site scripting (XSS), square measure oftentimes employed by perpetrators to ascertain a footing in a very targeted network. Next, Trojans and backdoor shells square measure typically wont to expand that foothold and make a persistent presence inside the targeted perimeter.
質問 # 241
A Java app uses outdated libraries with known CVEs. What risk does this create?
正解：D
解説：
Using outdated libraries with known vulnerabilities introduces supply chain risk because attackers can exploit publicly known CVEs in third-party components integrated into the application.
質問 # 242
A large company intends to use BlackBerry for corporate mobile phones and a security analyst is assigned to evaluate the possible threats. The analyst will use the Blackjacking attack method to demonstrate how an attacker could circumvent perimeter defenses and gain access to the corporate network. What tool should the analyst use to perform a Blackjacking attack?
正解：D
解説：
The Blackjacking attack involves leveraging a compromised BlackBerry device and its connection through the BlackBerry Enterprise Server (BES) to tunnel back into the internal corporate network, bypassing perimeter firewalls. The tool used in this method is BBProxy.
BBProxy is installed on the BlackBerry device and establishes a covert tunnel via BES, allowing attackers to pivot into the internal LAN from outside the perimeter.
Reference - CEH v13 Official Study Guide:
Module 17: Hacking Mobile Platforms
Quote:
"Blackjacking is a technique in which attackers use BBProxy to exploit a trusted path from a BlackBerry device to the corporate LAN through BES." Incorrect Options Explained:
A). Paros Proxy is a web proxy used for intercepting HTTP/S traffic.
C). Blooover is used for Bluetooth security auditing.
D). BBCrack is used for password recovery on BlackBerry devices, not for tunneling.
質問 # 243
A Certified Ethical Hacker (CEH) is given the task to perform an LDAP enumeration on a target system. The system is secured and accepts connections only on secure LDAP. The CEH uses Python for the enumeration process. After successfully installing LDAP and establishing a connection with the target, he attempts to fetch details like the domain name and naming context but is unable to receive the expected response. Considering the circumstances, which of the following is the most plausible reason for this situation?
正解：A
解説：
The most plausible reason for the situation is that the secure LDAP connection was not properly initialized due to a lack of 'use_ssl = True' in the server object creation. To use secure LDAP (LDAPS), the CEH needs to specify the use_ssl parameter as True when creating the server object with the ldap3 library in Python. This parameter tells the library to use SSL/TLS encryption for the LDAP communication. If the parameter is omitted or set to False, the library will use plain LDAP, which may not be accepted by the target system that only allows secure LDAP connections12. For example, the CEH can use the following code to create a secure LDAP server object:
from ldap3 import Server, Connection, ALL
server = Server('ldaps://<target_ip>', use_ssl=True, get_info=ALL)
connection = Connection(server, user='<username>', password='<password>') connection.bind() The other options are not as plausible as option B for the following reasons:
* A. The Python version installed on the CEH's machine is incompatible with the ldap3 library: This option is unlikely because the ldap3 library supports Python versions from 2.6 to 3.9, which covers most of the commonly used Python versions3. Moreover, if the Python version was incompatible, the CEH would not be able to install the library or import it in the code, and would encounter errors before establishing the connection.
* C. The enumeration process was blocked by the target system's intrusion detection system: This option is possible but not very plausible because the CEH was able to establish a connection with the target, which means the intrusion detection system did not block the initial handshake. Moreover, the enumeration process would not affect the response of the target system, but rather the visibility of the results. If the intrusion detection system detected and blocked the enumeration, the CEH would receive an error message or a blank response, not an unexpected response.
* D. The system failed to establish a connection due to an incorrect port number: This option is incorrect because the CEH was able to establish a connection with the target, which means the port number was correct. If the port number was incorrect, the CEH would not be able to connect to the target system at all, and would receive a connection refused error.
