ECCouncil Certified Ethical Hacker Exam (CEHv13) Sample Questions:

1. In Miami, Florida, Sarah Thompson, a security analyst at Apex Cyber Defense, is tasked with monitoring the wireless infrastructure at Coastal Healthcare, a busy urban hospital. One morning, nurse Emily Carter reports that her tablet used for accessing patient records is unexpectedly connecting to an access point broadcasting a name and signal similar to the hospital's secure Wi- Fi. Upon investigation, Sarah's log analysis reveals an unauthorized device on the network capturing sensitive traffic from connected systems. Suspecting a breach, she identifies that the attacker has deployed an access point to mimic the hospital's legitimate network. Based on this behavior, which wireless threat is the attacker executing?

A) Rogue AP
B) Evil Twin AP
C) Honeypot AP
D) Misconfigured AP

2. During a security assessment of a metropolitan public transportation terminal, a penetration tester examines a network-connected IoT surveillance camera system that is used for 24/7 video monitoring of high-traffic areas. Upon analyzing the camera's network traffic, the tester observes that it uses an outdated encryption protocol (SSLv2) to transmit video data to the control center.
The tester uses a network packet sniffer to intercept this traffic and easily decrypts the stream, successfully reconstructing full video footage in real time without authentication.
Further analysis reveals that the camera does not enforce TLS or any modern encryption standard and lacks support for mutual authentication or secure key exchange. Additionally, no integrity checks are performed, leaving the data open to manipulation.
What IoT vulnerability is most likely being exploited in this scenario?

A) Replay attack on wireless signals
B) Insecure data transfer and storage
C) Jamming attack on RF communication
D) Credential theft via web application

3. A financial institution in Chicago deploys an internal HTTPS-based customer portal that uses response compression to optimize bandwidth. During an authorized security assessment, a tester gains a vantage point along the communication path between internal clients and the gateway device.
By repeatedly initiating controlled requests and analyzing subtle differences in encrypted response sizes, the tester correlates variations in compressed output with specific input patterns.
Over time, this analysis enables extraction of portions of a protected authentication value transmitted within the secure channel.
Which session hijacking technique best describes this activity?

A) Forbidden attack
B) Man-in-the-Browser (MITB) attack
C) CRIME attack
D) Man-in-the-Middle (MITM) attack

4. A cybersecurity team at a regional healthcare provider is conducting an internal red team exercise to assess their exposure to service enumeration attacks. Amanda, a senior penetration tester, is assigned to probe the internal network for services that may reveal usernames, group information, or system details without requiring prior authentication. She decides to target common services running on specific ports that are often misconfigured or loosely monitored.
During her reconnaissance, Amanda identifies several open ports across various hosts and must now prioritize which ones to probe first for maximum information gain related to enumeration.
Which of the following services should Amanda target as a priority to enumerate usernames and group information without authentication?

A) TCP 25 and UDP 138
B) TCP 21 and UDP 137
C) TCP 139 and UDP 137, 138
D) TCP 23 and UDP 137, 138

5. A penetration tester is tasked with compromising a company's wireless network, which uses WPA2-PSK encryption. The tester wants to capture the WPA2 handshake and crack the pre- shared key. What is the most appropriate approach to achieve this?

A) Use a de-authentication attack to force a client to reconnect, capturing the WPA2 handshake
B) Conduct a Man-in-the-Middle attack by spoofing the router's MAC address
C) Execute a Cross-Site Scripting (XSS) attack on the router's admin panel
D) Perform a brute-force attack directly on the WPA2 encryption
