Q441. Shayla is an IT security consultant, specializing in social engineering and external penetration tests. Shayla has been hired on by Treks Avionics, a subcontractor for the Department of Defense. Shayla has been given authority to perform any and all tests necessary to audit the company's network security.
No employees for the company, other than the IT director, know about Shayla's work she will be doing. Shayla's first step is to obtain a list of employees through company website contact pages. Then she befriends a female employee of the company through an online chat website. After meeting with the female employee numerous times, Shayla is able to gain her trust and they become friends. One day, Shayla steals the employee's access badge and uses it to gain unauthorized access to the Treks Avionics offices.
What type of insider threat would Shayla be considered?
A. She would be considered an Insider Affiliate
B. Because she does not have any legal access herself, Shayla would be considered an Outside Affiliate
C. Shayla is an Insider Associate since she has befriended an actual employee
D. Since Shayla obtained access with a legitimate company badge; she would be considered a Pure Insider
Answer: A
Q442. You are scanning into the target network for the first time. You find very few conventional ports open. When you attempt to perform traditional service identification by connecting to the open ports, it yields either unreliable or no results. You are unsure of what protocols are being used. You need to discover as many different protocols as possible. Which kind of scan would you use to do this?
A. Nmap with the –sO (Raw IP packets) switch
B. Nessus scan with TCP based pings
C. Nmap scan with the –sP (Ping scan) switch
D. Netcat scan with the –u –e switches
Answer: A
Explanation: Running Nmap with the –sO switch will do a IP Protocol Scan. The IP protocol scan is a bit different than the other nmap scans. The IP protocol scan is searching for additional IP protocols in use by the remote station, such as ICMP, TCP, and UDP. If a router is scanned, additional IP protocols such as EGP or IGP may be identified.
Q443. In order to attack a wireless network, you put up an access point and override the signal of the real access point. As users send authentication data, you are able to capture it. What kind of attack is this?
A. WEP attack
B. Drive by hacking
C. Rogue access point attack
D. Unauthorized access point attack
Answer: C
Explanation: The definition of a Rogue access point is:1. A wireless access point (AP) installed by an employee without the consent of the IT department. Without the proper security configuration, users have exposed their company's network to the outside world.2. An access point (AP) set up by an attacker outside a facility with a wireless network. Also called an "evil twin," the rogue AP picks up beacons (signals that advertise its presence) from the company's legitimate AP and transmits identical beacons, which some client machines inside the building associate with.
Q444. What is SYSKEY # of bits used for encryption?
A. 40
B. 64
C. 128
D. 256
Answer: C
Explanation: System Key hotfix is an optional feature which allows stronger encryption of SAM. Strong encryption protects private account information by encrypting the password data using a 128-bit cryptographically random key, known as a password encryption key.
Q445. Nathalie would like to perform a reliable scan against a remote target. She is not concerned about being stealth at this point. Which of the following type of scans would be the most accurate and reliable?
A. A FIN Scan
B. A Half Scan
C. A UDP Scan
D. The TCP Connect Scan
Answer: D
Explanation: The connect() system call provided by your operating system is used to open a connection to every interesting port on the machine. If the port is listening, connect() will succeed, otherwise the port isn't reachable. One strong advantage to this technique is that you don't need any special privileges. This is the fastest scanning method supported by nmap, and is available with the -t (TCP) option. The big downside is that this sort of scan is easily detectable and filterable.
Q446. Bank of Timbuktu was a medium-sized, regional financial institution in Timbuktu. The bank has deployed a new Internet-accessible Web application recently, using which customers could access their account balances, transfer money between accounts, pay bills and conduct online financial business using a Web browser.
John Stevens was in charge of information security at Bank of Timbuktu. After one month in production, several customers complained about the Internet enabled banking application. Strangely, the account balances of many bank’s customers has been changed!
However, money hadn’t been removed from the bank. Instead, money was transferred between accounts. Given this attack profile, John Stevens reviewed the Web application’s logs and found the following entries:
Attempted login of unknown user: John Attempted login of unknown user: sysaR Attempted login of unknown user: sencat Attempted login of unknown user: pete ‘’; Attempted login of unknown user: ‘ or 1=1--Attempted login of unknown user: ‘; drop table logins--Login of user jason, sessionID= 0x75627578626F6F6B Login of user daniel, sessionID= 0x98627579539E13BE Login of user rebecca, sessionID= 0x90627579944CCB811 Login of user mike, sessionID= 0x9062757935FB5C64 Transfer Funds user jason Pay Bill user mike Logout of user mike
What kind of attack did the Hacker attempt to carry out at the bank? (Choose the best answer)
A. The Hacker attempted SQL Injection technique to gain access to a valid bank login ID.
B. The Hacker attempted Session hijacking, in which the Hacker opened an account with the bank, then logged in to receive a session ID, guessed the next ID and took over Jason’s session.
C. The Hacker attempted a brute force attack to guess login ID and password using password cracking tools.
D. The Hacker used a random generator module to pass results to the Web server and exploited Web application CGI vulnerability.
Answer: A
Explanation: The following part: Attempted login of unknown user: pete ‘’; Attempted login of unknown user: ‘ or 1=1--Attempted login of unknown user: ‘; drop table logins--Clearly shows a hacker trying to perform a SQL injection by bypassing the login with the statement 1=1 and then dumping the logins table.
Q447. After a client sends a connection request (SYN) packet to the server, the server will respond (SYN-ACK) with a sequence number of its choosing, which then must be acknowledge (ACK) by the client. This sequence number is predictable; the attack connects to a service first with its own IP address, records the sequence number chosen and then opens a second connection from a forget IP address. The attack doesn’t see the SYN-ACK (or any other packet) from the server, but can guess the correct responses. If the source IP Address is used for authentication, the attacker can use the one-side communication to break into the server.
What attacks can you successfully launch against a server using the above technique?
A. Session Hijacking attacks
B. Denial of Service attacks
C. Web Page defacement attacks
D. IP Spoofing Attacks
Answer: A
Explanation: The term Session Hijacking refers to the exploitation of a valid computer session -sometimes also called a session key - to gain unauthorised access to information or services in a computer system. In particular, it is used to refer to the theft of a magic cookie used to authenticate a user to a remote server. It has particular relevance to web developers, as the HTTP cookies used to maintain a session on many web sites can be easily stolen by an attacker using an intermediary computer or with access to the saved cookies on the victim's computer.

Q448. After an attacker has successfully compromised a remote computer, what would be one of the last steps that would be taken to ensure that the compromise is not traced back to the source of the problem?
A. Install pactehs
B. Setup a backdoor
C. Cover your tracks
D. Install a zombie for DDOS
Answer: C
Explanation: As a hacker you don’t want to leave any traces that could lead back to you.
Q449. 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.
