ECCouncil Certified Ethical Hacker Exam Sample Questions (Q182-Q187):

NEW QUESTION # 182
In the field of cryptanalysis, what is meant by a "rubber-hose" attack?

  • A. A backdoor placed into a cryptographic algorithm by its creator.
  • B. Extraction of cryptographic secrets through coercion or torture.
  • C. Forcing the targeted keystream through a hardware-accelerated device such as an ASIC.
  • D. Attempting to decrypt ciphertext by making logical assumptions about the contents of the original plaintext.

Answer: B

Explanation:
A powerful and often the most effective cryptanalysis method in which the attack is directed at the most vulnerable link in the cryptosystem - the person. In this attack, the cryptanalyst uses blackmail, threats, torture, extortion, bribery, etc. This method's main advantage is the decryption time's fundamental independence from the volume of secret information, the length of the key, and the cipher's mathematical strength.
The method can reduce the time to guess a password, for example, for AES, to an acceptable level; however, it requires special authorization from the relevant regulatory authorities. Therefore, it is outside the scope of this course and is not considered in its practical part.


NEW QUESTION # 183
In a large organization, a network security analyst discovered a series of packet captures that seem unusual.
The network operates on a switched Ethernet environment. The security team suspects that an attacker might be using a sniffer tool. Which technique could the attacker be using to successfully carry out this attack, considering the switched nature of the network?

  • A. The attacker might be implementing MAC flooding to overwhelm the switch's memory
  • B. The attacker might be using passive sniffing, as it provides significant stealth advantages
  • C. The attacker might be compromising physical security to plug into the network directly
  • D. The attacker is probably using a Trojan horse with in-built sniffing capability

Answer: A

Explanation:
A sniffer tool is a software or hardware device that can capture and analyze network traffic. In a switched Ethernet environment, where each port on a switch is connected to a single device, a sniffer tool can only see the traffic that is destined for or originated from the device it is attached to. However, an attacker can use various techniques to overcome this limitation and sniff the traffic of other devices on the same network. One of these techniques is MAC flooding, which exploits the finite memory of the switch's MAC address table.
The attacker sends a large number of frames with different source MAC addresses to the switch, which fills up the MAC address table and causes the switch to enter a fail-open mode, where it broadcasts all incoming frames to all ports, regardless of the destination MAC address. This way, the attacker can see all the traffic on the network and capture it with a sniffer tool.
The other options are less likely or less effective techniques for sniffing a switched Ethernet network.
Compromising physical security to plug into the network directly may allow the attacker to sniff the traffic of the device they are connected to, but not the traffic of other devices on the network. Using a Trojan horse with in-built sniffing capability may allow the attacker to sniff the traffic of the infected device, but not the traffic of other devices on the network, unless the Trojan horse also performs MAC flooding or other techniques to bypass the switch. Using passive sniffing, which involves listening to the network traffic without sending any packets, may provide significant stealth advantages, but it does not help the attacker to see the traffic of other devices on the network, unless the switch is already in fail-open mode or the attacker uses other techniques to induce it.

NEW QUESTION # 184
Don, a student, came across a gaming app in a third-party app store and Installed it. Subsequently, all the legitimate apps in his smartphone were replaced by deceptive applications that appeared legitimate. He also received many advertisements on his smartphone after Installing the app. What is the attack performed on Don in the above scenario?

  • A. Clickjacking
  • B. SIM card attack
  • C. Agent Smith attack
  • D. SMS phishing attack

Answer: C

Explanation:
Agent Smith Attack
Agent Smith attacks are carried out by luring victims into downloading and installing malicious apps designed and published by attackers in the form of games, photo editors, or other attractive tools from third-party app stores such as 9Apps. Once the user has installed the app, the core malicious code inside the application infects or replaces the legitimate apps in the victim's mobile device C&C commands. The deceptive application replaces legitimate apps such as WhatsApp, SHAREit, and MX Player with similar infected versions. The application sometimes also appears to be an authentic Google product such as Google Updater or Themes. The attacker then produces a massive volume of irrelevant and fraudulent advertisements on the victim's device through the infected app for financial gain. Attackers exploit these apps to steal critical information such as personal information, credentials, and bank details, from the victim's mobile device through C&C commands.


NEW QUESTION # 185
Ron, a security professional, was pen testing web applications and SaaS platforms used by his company. While testing, he found a vulnerability that allows hackers to gain unauthorized access to API objects and perform actions such as view, update, and delete sensitive data of the company. What is the API vulnerability revealed in the above scenario?

  • A. Code injections
  • B. No ABAC validation
  • C. Improper use of CORS
  • D. Business logic flaws

Answer: B


NEW QUESTION # 186
Which of the following tools performs comprehensive tests against web servers, including dangerous files and CGIs?

  • A. Nikto
  • B. Dsniff
  • C. Snort
  • D. John the Ripper

Answer: A

Explanation:
https://en.wikipedia.org/wiki/Nikto_(vulnerability_scanner)
Nikto is a free software command-line vulnerability scanner that scans web servers for dangerous files/CGIs, outdated server software, and other problems. It performs generic and server types specific checks. It also captures and prints any cookies received. The Nikto code itself is free software, but the data files it uses to drive the program are not.
