A. Lee is seeing activity indicative of a Smurf attack.
B. Most likely, the ICMP packets are being sent in this manner to attempt IP spoofing.
C. Lee is seeing a Ping of death attack.
D. This is not unusual traffic, ICMP packets can be of any size.

Q4. When writing shellcodes, you must avoid _________________ because these will end the string.
A. Null Bytes
B. Root Bytes
C. Char Bytes
D. Unicode Bytes
Answer: A
Explanation: The null character (also null terminator) is a character with the value zero, present in the ASCII and Unicode character sets, and available in nearly all mainstream programming languages. The original meaning of this character was like NOP — when sent to a printer or a terminal, it does nothing (some terminals, however, incorrectly display it as space). Strings ending in a null character are said to be null-terminated.
Q5. Steven the hacker realizes the network administrator of Acme Corporation is using syskey in Windows 2008 Server to protect his resources in the organization. Syskey independently encrypts the hashes so that physical access to the server, tapes, or ERDs is only first step to cracking the passwords. Steven must break through the encryption used by syskey before he can attempt to use brute force dictionary attacks on the hashes. Steven runs a program called "SysCracker" targeting the Windows 2008 Server machine in attempting to crack the hash used by Syskey. He needs to configure the encryption level before he can launch the attack. How many bits does Syskey use for encryption?
A. 40-bit encryption
B. 128-bit encryption
C. 256-bit encryption
D. 64-bit encryption
Answer: B
Q6. 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
Q7. Which of the following ICMP message types are used for destinations unreachables?
A. 0
B. 3
C. 11
D. 13
E. 17
Answer: B
Explanation: Type 3 messages are used for unreachable messages. 0 is Echo Reply, 8 is Echo request, 11 is time exceeded, 13 is timestamp and 17 is subnet mask request. Learning these would be advisable for the test.
Q8. Exhibit:
You are conducting pen-test against a company’s website using SQL Injection techniques. You enter “anuthing or 1=1-“ in the username filed of an authentication form. This is the output returned from the server.
What is the next step you should do?
A. Identify the user context of the web application by running_
http://www.example.com/order/include_rsa_asp?pressReleaseID=5
AND
USER_NAME() = ‘dbo’
B. Identify the database and table name by running:
http://www.example.com/order/include_rsa.asp?pressReleaseID=5 AND ascii(lower(substring((SELECT TOP 1 name FROM sysobjects WHERE xtype=’U’),1))) > 109
C. Format the C: drive and delete the database by running: http://www.example.com/order/include_rsa.asp?pressReleaseID=5 AND xp_cmdshell ‘format c: /q /yes ‘; drop database myDB; --
D. Reboot the web server by running: http://www.example.com/order/include_rsa.asp?pressReleaseID=5 AND xp_cmdshell ‘iisreset –reboot’; --
Answer: A
Q9. You are the security administrator of Jaco Banking Systems located in Boston. You are setting up e-banking website (http://www.ejacobank.com) authentication system. Instead of issuing banking customer with a single password, you give them a printed list of 100 unique passwords. Each time the customer needs to log into the e-banking system website, the customer enters the next password on the list. If someone sees them type the password using shoulder surfing, MiTM or keyloggers, then no damage is done because the password will not be accepted a second time. Once the list of 100 passwords is almost finished, the system automatically sends out a new password list by encrypted e-mail to the customer.
You are confident that this security implementation will protect the customer from password abuse.
Two months later, a group of hackers called "HackJihad" found a way to access the one-time password list issued to customers of Jaco Banking Systems. The hackers set up a fake website (http://www.e-jacobank.com) and used phishing attacks to direct ignorant customers to it. The fake website asked users for their e-banking username and password, and the next unused entry from their one-time password sheet. The hackers collected 200 customer's username/passwords this way. They transferred money from the customer's bank account to various offshore accounts.
Your decision of password policy implementation has cost the bank with USD 925,000 to hackers. You immediately shut down the e-banking website while figuring out the next best security solution
What effective security solution will you recommend in this case?
A. Implement Biometrics based password authentication system. Record the customers face image to the authentication database
B. Configure your firewall to block logon attempts of more than three wrong tries
C. Enable a complex password policy of 20 characters and ask the user to change the password immediately after they logon and do not store password histories
D. Implement RSA SecureID based authentication system
Answer: D
Q10. Annie has just succeeded in stealing a secure cookie via a XSS attack. She is able to replay the cookie even while the session is valid on the server. Why do you think this is possible?
A. Any cookie can be replayed irrespective of the session status
B. The scenario is invalid as a secure cookie cannot be replayed
C. It works because encryption is performed at the network layer (layer 1 encryption)
D. It works because encryption is performed at the application layer (single encryption key)
Answer: D
