B. You threaten to use the rubber hose on someone unless they reveal their password
C. You load a dictionary of words into your cracking program
D. You create hashes of a large number of words and compare it with the encrypted passwords
E. You wait until the password expires
Answer: A
Explanation: Brute force cracking is a time consuming process where you try every possible combination of letters, numbers, and characters until you discover a match.
Q2. Most cases of insider abuse can be traced to individuals who are introverted, incapable of dealing with stress or conflict, and frustrated with their job, office politics, and lack of respect or promotion. Disgruntled employees may pass company secrets and intellectual property to competitors for monitory benefits.
Here are some of the symptoms of a disgruntled employee:
a. Frequently leaves work early, arrive late or call in sick
b. Spends time surfing the Internet or on the phone
c. Responds in a confrontational, angry, or overly aggressive way to simple requests or comments
d. Always negative; finds fault with everything
These disgruntled employees are the biggest threat to enterprise security. How do you deal with these threats? (Select 2 answers)
A. Limit access to the applications they can run on their desktop computers and enforce strict work hour rules
B. By implementing Virtualization technology from the desktop to the data centre, organizations can isolate different environments with varying levels of access and security to various employees
C. Organizations must ensure that their corporate data is centrally managed and delivered to users just and when needed
D. Limit Internet access, e-mail communications, access to social networking sites and job hunting portals
Answer: BC
Q3. What type of port scan is shown below?
A. Idle Scan
B. Windows Scan
C. XMAS Scan
D. SYN Stealth Scan
Answer: C
Explanation: An Xmas port scan is variant of TCP port scan. This type of scan tries to obtain information about the state of a target port by sending a packet which has multiple TCP flags set to 1 - "lit as an Xmas tree". The flags set for Xmas scan are FIN, URG and PSH. The purpose is to confuse and bypass simple firewalls. Some stateless firewalls only check against security policy those packets which have the SYN flag set (that is, packets that initiate connection according to the standards). Since Xmas scan packets are different, they can pass through these simple systems and reach the target host.
Q4. Which type of attack is port scanning?
A. Web server attack
B. Information gathering
C. Unauthorized access
D. Denial of service attack
Answer: B
Q5. Joe Hacker is going wardriving. He is going to use PrismStumbler and wants it to go to a GPS mapping software application. What is the recommended and well-known GPS mapping package that would interface with PrismStumbler?
Select the best answer.
A. GPSDrive
B. GPSMap
C. WinPcap
D. Microsoft Mappoint
Answer: A
Explanations:
GPSDrive is a Linux GPS mapping package. It recommended to be used to send PrismStumbler data to so that it can be mapped. GPSMap is a generic term and not a real software package. WinPcap is a packet capture library for Windows. It is used to capture packets and deliver them to other programs for analysis. As it is for Windows, it isn't going to do what Joe Hacker is wanting to do. Microsoft Mappoint is a Windows application. PrismStumbler is a Linux application. Thus, these two are not going to work well together.
Q6. Dan is conducting a penetration testing and has found a vulnerability in a Web Application which gave him the sessionID token via a cross site scripting vulnerability. Dan wants to replay this token. However, the session ID manager (on the server) checks the originating IP address as well. Dan decides to spoof his IP address in order to replay the sessionID. Why do you think Dan might not be able to get an interactive session?
A. Dan cannot spoof his IP address over TCP network
B. The server will send replies back to the spoofed IP address
C. Dan can establish an interactive session only if he uses a NAT
D. The scenario is incorrect as Dan can spoof his IP and get responses
Answer: B
Explanation: Spoofing your IP address is only effective when there is no need to establish a two way connection as all traffic meant to go to the attacker will end up at the place of the spoofed address.
Q7. Which of the following tool would be considered as Signature Integrity Verifier (SIV)?
A. Nmap
B. SNORT
C. VirusSCAN
D. Tripwire
Answer: D
Q8. Which of the following is NOT part of CEH Scanning Methodology?
A. Check for Live systems
B. Check for Open Ports
C. Banner Grabbing
D. Prepare Proxies
E. Social Engineering attacks
F. Scan for Vulnerabilities
G. Draw Network Diagrams
Answer: E
Q9. You are scanning the target network for the first time. You are able to detect few convention open ports. While attempting to perform conventional service identification by connecting to the open ports, the scan yields either bad or no result. As you are unsure of the protocols in use, you want to discover as many different protocols as possible. Which of the following scan options can help you achieve this?
A. Nessus sacn with TCP based pings
B. Netcat scan with the switches
C. Nmap scan with the P (ping scan) switch
D. Nmap with the O (Raw IP Packets switch
Answer: D
Explanation: -sO IP protocol scans: This method is used to determine which IP protocols are supported on a host. The technique is to send raw IP packets without any further protocol header to each specified protocol on the target machine. If we receive an ICMP protocol unreachable message, then the protocol is not in use. Otherwise we assume it is open. Note that some hosts (AIX, HP-UX, Digital UNIX) and firewalls may not send protocol unreachable messages.
Q10. You suspect that your Windows machine has been compromised with a Trojan virus. When you run anti-virus software it does not pick of the Trojan. Next you run netstat command to look for open ports and you notice a strange port 6666 open.
What is the next step you would do?
A. Re-install the operating system.
B. Re-run anti-virus software.
C. Install and run Trojan removal software.
D. Run utility fport and look for the application executable that listens on port 6666.
Answer: D
Explanation: Fport reports all open TCP/IP and UDP ports and maps them to the owning application. This is the same information you would see using the 'netstat -an' command, but it also maps those ports to running processes with the PID, process name and path. Fport can be used to quickly identify unknown open ports and their associated applications.
