Q1. Web servers often contain directories that do not need to be indexed. You create a text file with search engine indexing restrictions and place it on the root directory of the Web Server.
User-agent: * Disallow: /images/ Disallow: /banners/ Disallow: /Forms/ Disallow: /Dictionary/ Disallow: /_borders/ Disallow: /_fpclass/ Disallow: /_overlay/ Disallow: /_private/ Disallow: /_themes/ What is the name of this file?
A. robots.txt
B. search.txt
C. blocklist.txt
D. spf.txt
Answer: A
Q2. Dave has been assigned to test the network security of Acme Corp. The test was announced to the employees. He created a webpage to discuss the progress of the tests with employees who were interested in following the test. Visitors were allowed to click on a sand clock to mark the progress of the test. Dave successfully embeds a keylogger. He also added some statistics on the webpage. The firewall protects the network well and allows strict Internet access. How was security compromised and how did the firewall respond?
A. The attack did not fall through as the firewall blocked the traffic
B. The attack was social engineering and the firewall did not detect it
C. The attack was deception and security was not directly compromised
D. Security was not compromised as the webpage was hosted internally
Answer: B
Explanation: This was just another way to trick the information out of the users without the need to hack into any systems. All traffic is outgoing and initiated by the user so the firewall will not react.
Q3. Null sessions are un-authenticated connections (not using a username or password.) to an NT or 2000 system. Which TCP and UDP ports must you filter to check null sessions on your network?
A. 137 and 139
B. 137 and 443
C. 139 and 443
D. 139 and 445
Answer: D
Explanation: NULL sessions take advantage of “features” in the SMB (Server Message Block) protocol that exist primarily for trust relationships. You can establish a NULL session with a Windows host by logging on with a NULL user name and password. Primarily the following ports are vulnerable if they are accessible: 139 TCP NETBIOS Session Service 139 UDP NETBIOS Session Service 445 TCP SMB/CIFS
Q4. What type of Trojan is this?
A. RAT Trojan
B. E-Mail Trojan
C. Defacement Trojan
D. Destructing Trojan
E. Denial of Service Trojan
Answer: C
Q5. Which of the following is an attack in which a secret value like a hash is captured and then reused at a later time to gain access to a system without ever decrypting or decoding the hash.
A. Replay Attacks
B. Brute Force Attacks
C. Cryptography Attacks
D. John the Ripper Attacks
Answer: A
Explanation: A replay attack is a form of network attack in which a valid data transmission is maliciously or fraudulently repeated or delayed. This is carried out either by the originator or by an adversary who intercepts the data and retransmits it.
Q6. You are having problems while retrieving results after performing port scanning during internal testing. You verify that there are no security devices between you and the target system. When both stealth and connect scanning do not work, you decide to perform a NULL scan with NMAP. The first few systems scanned shows all ports open.
Which one of the following statements is probably true?
A. The systems have all ports open.
B. The systems are running a host based IDS.
C. The systems are web servers.
D. The systems are running Windows.
Answer: D
Explanation: The null scan turns off all flags, creating a lack of TCP flags that should never occur in the real world. If the port is closed, a RST frame should be returned and a null scan to an open port results in no response. Unfortunately Microsoft (like usual) decided to completely ignore the standard and do things their own way. Thus this scan type will not work against systems running Windows as they choose not to response at all. This is a good way to distinguish that the system being scanned is running Microsoft Windows.
Q7. You find the following entries in your web log. Each shows attempted access to either root.exe or cmd.exe. What caused this?
GET /scripts/root.exe?/c+dir GET /MSADC/root.exe?/c+dir GET /c/winnt/system32/cmd.exe?/c+dir GET /d/winnt/system32/cmd.exe?/c+dir GET /scripts/..%5c../winnt/system32/cmd.exe?/c+dir GET /_vti_bin/..%5c../..%5c../..%5c../winnt/system32/cmd.exe?/c+dir GET /_mem_bin/..%5c../..%5c../..%5c../winnt/system32/cmd.exe?/c+dir GET /msadc/..%5c../..%5c../..%5c/..xc1x1c../..xc1x1c../..xc1x1c../winnt/system32/cmd.exe?/c+dir GET /scripts/..xc1x1c../winnt/system32/cmd.exe?/c+dir GET /scripts/..xc0/../winnt/system32/cmd.exe?/c+dir GET /scripts/..xc0xaf../winnt/system32/cmd.exe?/c+dir GET /scripts/..xc1x9c../winnt/system32/cmd.exe?/c+dir GET /scripts/..%35c../winnt/system32/cmd.exe?/c+dir GET /scripts/..%35c../winnt/system32/cmd.exe?/c+dir GET /scripts/..%5c../winnt/system32/cmd.exe?/c+dir GET /scripts/..%2f../winnt/system32/cmd.exe?/c+dir
A. The Morris worm
B. The PIF virus
C. Trinoo
D. Nimda
E. Code Red
F. Ping of Death
Answer: D
Explanation: The Nimda worm modifies all web content files it finds. As a result, any user browsing web content on the system, whether via the file system or via a web server, may download a copy of the worm. Some browsers may automatically execute the downloaded copy, thereby, infecting the browsing system. The high scanning rate of the Nimda worm may also cause bandwidth denial-of-service conditions on networks with infected machines and allow intruders the ability to execute arbitrary commands within the Local System security context on machines running the unpatched versions of IIS.
Q8. Bob is a Junior Administrator at ABC.com is searching the port number of POP3 in a file. The partial output of the file is look like:
In which file he is searching?
A. services
B. protocols
C. hosts
D. resolve.conf
Answer: A
Explanation: The port numbers on which certain standard services are offered are defined in the RFC 1700 Assigned Numbers. The /etc/services file enables server and client programs to convert service names to these numbers -ports. The list is kept on each host and it is stored in the file /etc/services.
Q9. Steven is the senior network administrator for Onkton Incorporated, an oil well drilling company in Oklahoma City. Steven and his team of IT technicians are in charge of keeping inventory for the entire company; including computers, software, and oil well equipment. To keep track of everything, Steven has decided to use RFID tags on their entire inventory so they can be scanned with either a wireless scanner or a handheld scanner. These RFID tags hold as much information as possible about the equipment they are attached to. When Steven purchased these tags, he made sure they were as state of the art as possible. One feature he really liked was the ability to disable RFID tags if necessary. This comes in very handy when the company actually sells oil drilling equipment to other companies. All Steven has to do is disable the RFID tag on the sold equipment and it cannot give up any information that was previously stored on it.
What technology allows Steven to disable the RFID tags once they are no longer needed?
A. Newer RFID tags can be disabled by using Terminator Switches built into the chips
B. RFID Kill Switches built into the chips enable Steven to disable them
C. The company's RFID tags can be disabled by Steven using Replaceable ROM technology
D. The technology used to disable an RFIP chip after it is no longer needed, or possibly stolen, is called RSA Blocking

Q10. While reviewing the results of a scan run against a target network you come across the following:
What was used to obtain this output?
A. An SNMP Walk
B. Hping2 diagnosis
C. A Bo2K System query
D. Nmap protocol/port scan
Answer: A
Explanation: The snmpwalk command is designed to perform a sequence of chained GETNEXT requests automatically, rather than having to issue the necessary snmpgetnext requests by hand. The command takes a single OID, and will display a list of all the results which lie within the subtree rooted on this OID.
Q11. What is the correct order of steps in CEH System Hacking Cycle?

Q12. Harold just got home from working at Henderson LLC where he works as an IT technician. He was able to get off early because they were not too busy. When he walks into his home office, he notices his teenage daughter on the computer, apparently chatting with someone online. As soon as she hears Harold enter the room, she closes all her windows and tries to act like she was playing a game. When Harold asks her what she was doing, she acts very nervous and does not give him a straight answer. Harold is very concerned because he does not want his daughter to fall victim to online predators and the sort. Harold doesn't necessarily want to install any programs that will restrict the sites his daughter goes to, because he doesn't want to alert her to his trying to figure out what she is doing. Harold wants to use some kind of program that will track her activities online, and send Harold an email of her activity once a day so he can see what she has been up to. What kind of software could Harold use to accomplish this?
A. Install hardware Keylogger on her computer
B. Install screen capturing Spyware on her computer
C. Enable Remote Desktop on her computer
D. Install VNC on her computer
Answer: B
Q13. A rootkit is a collection of tools (programs) that enable administrator-level access to a computer. This program hides itself deep into an operating system for malicious activity and is extremely difficult to detect. The malicious software operates in a stealth fashion by hiding its files, processes and registry keys and may be used to create a hidden directory or folder designed to keep out of view from a user's operating system and security software.
What privilege level does a rootkit require to infect successfully on a Victim's machine?
A. User level privileges
B. Ring 3 Privileges
C. System level privileges
D. Kernel level privileges
Answer: D

Q15. What is the command used to create a binary log file using tcpdump?
A. tcpdump -r log
B. tcpdump -w ./log
C. tcpdump -vde -r log
D. tcpdump -l /var/log/
Answer: B
Explanation: tcpdump [ -adeflnNOpqStvx ] [ -c count ] [ -F file ] [ -i interface ] [ -r file ] [ -s snaplen ] [ -T type ] [ -w file ] [ expression ]
-w Write the raw packets to file rather than parsing and printing them out.
