NEW QUESTION # 108
The network administrator at Spears Technology, Inc has configured the default gateway Cisco router's access- list.
You successfully brute-force the SNMP community string using a SNMP crack tool.
The access-list prevents you from establishing a successful connection.
You want to retrieve the Cisco configuration from the router. How would you proceed?
- A. Use the Cisco's TFTP default password to connect and download the configuration file
- B. Run Generic Routing Encapsulation (GRE) tunneling protocol from your computer to the router masking your IP address
- C. Send a customized SNMP set request with a spoofed source IP address in the range -192.168.1.0
- D. Run a network sniffer and capture the returned traffic with the configuration file from the router
Answer: C
Explanation:
If SNMP access is restricted to specific IP addresses (e.g., 192.168.1.0/24), you can bypass access controls by:
* Spoofing the source IP to fall within that allowed range.
* Using a SNMP set request to instruct the device (e.g., to copy its configuration to a TFTP server).
This is a classic SNMP spoofing attack.

- C. Cavity virus
- D. Macro virus
Answer: A
NEW QUESTION # 110
When a normal TCP connection starts, a destination host receives a SYN (synchronize/start) packet from a source host and sends back a SYN/ACK (synchronize acknowledge). The destination host must then hear an ACK (acknowledge) of the SYN/ACK before the connection is established. This is referred to as the "TCP three-way handshake." While waiting for the ACK to the SYN ACK, a connection queue of finite size on the destination host keeps track of connections waiting to be completed. This queue typically empties quickly since the ACK is expected to arrive a few milliseconds after the SYN ACK.
How would an attacker exploit this design by launching TCP SYN attack?
- A. Attacker generates TCP RST packets with random source addresses towards a victim host
- B. Attacker generates TCP ACK packets with random source addresses towards a victim host
- C. Attacker generates TCP SYN packets with random destination addresses towards a victim host
- D. Attacker floods TCP SYN packets with random source addresses towards a victim host
Answer: D
NEW QUESTION # 111
Why is a penetration test considered to be more thorough than a vulnerability scan?
- A. The tools used by penetration testers tend to have much more comprehensive vulnerability databases.
- B. It is not - a penetration test is often performed by an automated tool, while a vulnerability scan requires active engagement.
- C. Vulnerability scans only do host discovery and port scanning by default.
- D. A penetration test actively exploits vulnerabilities in the targeted infrastructure, while a vulnerability scan does not typically involve active exploitation.
Answer: D
Explanation:
A vulnerability scan identifies known vulnerabilities by comparing system configurations and software versions against a database. It is mostly passive and does not confirm if vulnerabilities are exploitable.
Penetration testing, however, involves simulating real-world attacks. It attempts to actively exploit vulnerabilities, escalate privileges, and access sensitive data, offering a more realistic view of risk.
Reference - CEH v13 Official Study Guide:
Module 1: Introduction to Ethical Hacking
Quote:
"A penetration test goes beyond vulnerability identification by actively exploiting weaknesses to assess the actual risk and potential impact to the organization." Incorrect Options:
A). Scans do more than port scanning.
C). Penetration testing is often manual and detailed.
D). The difference is methodology, not just database size.
NEW QUESTION # 112
In this attack, a victim receives an e-mail claiming to be from PayPal stating that their account has been disabled and confirmation is required before activation. The attackers then scam to collect not one but two credit card numbers, ATM PIN, and other personal details. Ignorant users usually fall prey to this scam.
Which of the following statement is incorrect related to this attack?
- A. Do not reply to email messages or popup ads asking for personal or financial information
- B. Review credit card and bank account statements regularly
- C. Do not trust telephone numbers in e-mails or popup ads
- D. Antivirus, anti-spyware, and firewall software can very easily detect these types of attacks
- E. Do not send credit card numbers, and personal or financial information via e-mail
Answer: D
Explanation:
This is a classic phishing scam - a form of social engineering used to trick victims into giving up sensitive information.
Statement D is incorrect because:
* Antivirus, anti-spyware, and firewalls are primarily designed to stop malware and network intrusions.
* They cannot reliably detect social engineering attacks like phishing emails, especially if the email content appears legitimate.
* Detection of phishing is more reliant on user awareness and email filtering policies.
From CEH v13 Courseware:
* Module 7: Social Engineering
* Module 5: Email Security
CEH v13 Study Guide states:
"Phishing attacks are psychological rather than purely technical. Antivirus tools cannot detect or prevent all phishing attempts because these are based on user manipulation rather than system compromise."

NEW QUESTION # 113
What does a firewall check to prevent particular ports and applications from getting packets into an organization?
- A. Network layer headers and the session layer port numbers
- B. Transport layer port numbers and application layer headers
- C. Application layer port numbers and the transport layer headers
- D. Presentation layer headers and the session layer port numbers
Answer: B
Explanation:
Firewalls primarily operate at Layer 3 (Network) and Layer 4 (Transport) of the OSI model. They inspect:
IP headers (Layer 3)
TCP/UDP port numbers (Layer 4)
Application-specific data in Layer 7-aware firewalls (for application filtering) By examining transport layer port numbers and application layer headers, firewalls can block or allow traffic based on services like HTTP (port 80), FTP (port 21), and others.
Reference - CEH v13 Official Study Guide:
Module 13: Evading IDS, Firewalls, and Honeypots
Quote:
"Firewalls filter traffic based on IP addresses, transport-layer port numbers, and application protocol headers to control access to services and applications." Incorrect Options:
B & C. Presentation and session layers are not relevant to firewall rule inspection.
D). Application layer doesn't have port numbers; they are part of the transport layer.
NEW QUESTION # 114
The establishment of a TCP connection involves a negotiation called three-way handshake. What type of message does the client send to the server in order to begin this negotiation?
- A. ACK
- B. RST
- C. SYN-ACK
- D. SYN
Answer: D
NEW QUESTION # 115
Matthew, a black hat, has managed to open a meterpreter session to one of the kiosk machines in Evil Corp's lobby. He checks his current SID, which is:
S-1-5-21-1223352397-1872883824-861252104-501
What needs to happen before Matthew has full administrator access?
- A. He already has admin privileges, as shown by the "501" at the end of the SID.
- B. He needs to disable antivirus protection.
- C. He must perform privilege escalation.
- D. He needs to gain physical access.
Answer: C
Explanation:
Comprehensive and Detailed Explanation:
In Windows SID structure:
* RID 500 = Default Administrator
* RID 501 = Guest Account
Therefore, "-501" at the end indicates Matthew is operating as the Guest user, which has very limited privileges. To gain full administrative control, he must escalate his privileges.

Log monitoring tools performing behavioral analysis have alerted several suspicious logins on a Linux server occurring during non-business hours. After further examination of all login activities, it is noticed that none of the logins have occurred during typical work hours. A Linux administrator who is investigating this problem realizes the system time on the Linux server is wrong by more than twelve hours. What protocol used on Linux servers to synchronize the time has stopped working?
- A. Time Keeper
- B. OSPP
- C. PPP
- D. NTP
Answer: D
Explanation:
Comprehensive and Detailed Explanation From CEH v13 Guide:
The Network Time Protocol (NTP) is used by systems, including Linux servers, to synchronize their clocks with a time server. If NTP fails, time discrepancies may lead to inaccurate log records and affect security monitoring.
CEH v13 Reference:
Module 17: Evading IDS, Firewalls, and Honeypots - Log Tampering
"Accurate timekeeping is essential for proper logging and correlation. NTP ensures system time is synchronized across hosts."

NEW QUESTION # 122
Samuel a security administrator, is assessing the configuration of a web server. He noticed that the server permits SSlv2 connections, and the same private key certificate is used on a different server that allows SSLv2 connections. This vulnerability makes the web server vulnerable to attacks as the SSLv2 server can leak key information.
Which of the following attacks can be performed by exploiting the above vulnerability?
- A. Side-channel attack
- B. DROWN attack
- C. Padding oracle attack
- D. DUHK attack
Answer: B
Explanation:
DROWN is a serious vulnerability that affects HTTPS and other services that deem SSL and TLS, some of the essential cryptographic protocols for net security. These protocols allow everyone on the net to browse the net, use email, look on-line, and send instant messages while not third-parties being able to browse the communication.
DROWN allows attackers to break the encryption and read or steal sensitive communications, as well as passwords, credit card numbers, trade secrets, or financial data. At the time of public disclosure on March
2016, our measurements indicated thirty third of all HTTPS servers were vulnerable to the attack. fortuitously, the vulnerability is much less prevalent currently. As of 2019, SSL Labs estimates that one.2% of HTTPS servers are vulnerable.
What will the attackers gain?
Any communication between users and the server. This typically includes, however isn't limited to, usernames and passwords, credit card numbers, emails, instant messages, and sensitive documents. under some common scenarios, an attacker can also impersonate a secure web site and intercept or change the content the user sees.
Who is vulnerable?
Websites, mail servers, and other TLS-dependent services are in danger for the DROWN attack. At the time of public disclosure, many popular sites were affected. we used Internet-wide scanning to live how many sites are vulnerable:
Operators of vulnerable servers got to take action. there's nothing practical that browsers or end-users will do on their own to protect against this attack.
Is my site vulnerable?
Modern servers and shoppers use the TLS encryption protocol. However, because of misconfigurations, several servers also still support SSLv2, a 1990s-era precursor to TLS. This support did not matter in practice, since no up-to-date clients really use SSLv2. Therefore, despite the fact that SSLv2 is thought to be badly insecure, until now, simply supporting SSLv2 wasn't thought of a security problem, is a clients never used it.
DROWN shows that merely supporting SSLv2 may be a threat to fashionable servers and clients. It modern associate degree attacker to modern fashionable TLS connections between up-to-date clients and servers by sending probes to a server that supports SSLv2 and uses the same private key.
A server is vulnerable to DROWN if:
* It allows SSLv2 connections. This is surprisingly common, due to misconfiguration and inappropriate default settings.
* Its private key is used on any other serverthat allows SSLv2 connections, even for another protocol.
Many companies reuse the same certificate and key on their web and email servers, for instance. In this case, if the email server supports SSLv2 and the web server does not, an attacker can take advantage of the email server to break TLS connections to the web server.
How do I protect my server?
To protect against DROWN, server operators need to ensure that their private keys software used anyplace with server computer code that enables SSLv2 connections. This includes net servers, SMTP servers, IMAP and POP servers, and the other software that supports SSL/TLS.
Disabling SSLv2 is difficult and depends on the particular server software. we offer instructions here for many common products:
OpenSSL: OpenSSL may be a science library employed in several server merchandise. For users of OpenSSL, the simplest and recommended solution is to upgrade to a recent OpenSSL version. OpenSSL 1.0.2 users ought to upgrade to 1.0.2g. OpenSSL 1.0.1 users ought to upgrade to one.0.1s. Users of older OpenSSL versions ought to upgrade to either one in every of these versions. (Updated March thirteenth, 16:00 UTC) Microsoft IIS (Windows Server): Support for SSLv2 on the server aspect is enabled by default only on the OS versions that correspond to IIS 7.0 and IIS seven.5, particularly Windows scene, Windows Server 2008, Windows seven and Windows Server 2008R2. This support is disabled within the appropriate SSLv2 subkey for 'Server', as outlined in KB245030. albeit users haven't taken the steps to disable SSLv2, the export-grade and 56-bit ciphers that build DROWN possible don't seem to be supported by default.
Network Security Services (NSS): NSS may be a common science library designed into several server merchandise. NSS versions three.13 (released back in 2012) and higher than ought to have SSLv2 disabled by default. (A little variety of users might have enabled SSLv2 manually and can got to take steps to disable it.) Users of older versions ought to upgrade to a more moderen version. we tend to still advocate checking whether or not your non-public secret is exposed elsewhere Other affected software and in operation systems:
Instructions and data for: Apache, Postfix, Nginx, Debian, Red Hat
Browsers and other consumers: practical nothing practical that net browsers or different client computer code will do to stop DROWN. only server operators ar ready to take action to guard against the attack.
