CPEH-001 Exam Questions and Answers

QUESTION: 16

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?

Implement Biometrics based password authentication system. Record the customers face image to the authentication database
Configure your firewall to block logon attempts of more than three wrong tries
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
Implement RSA SecureID based authentication system

QUESTION: 17

More sophisticated IDSs look for common shellcode signatures. But even these systems can be bypassed, by using polymorphic shellcode. This is a technique common among virus writers ?it basically hides the true nature of the shellcode in different disguises. How does a polymorphic shellcode work?

They encrypt the shellcode by XORing values over the shellcode, using loader code to decrypt the shellcode, and then executing the decrypted shellcode
They convert the shellcode into Unicode, using loader to convert back to machine code then executing them
They reverse the working instructions into opposite order by masking the IDS signatures
They compress shellcode into normal instructions, uncompress the shellcode using loader code and then executing the shellcode

QUESTION: 20

The following script shows a simple SQL injection. The script builds an SQL query by concatenating hard-coded strings together with a string entered by the user:

The user is prompted to enter the name of a city on a Web form. If she enters Chicago, the query assembled by the script looks similar to the following:
SELECT * FROM OrdersTable WHERE ShipCity = 'Chicago'

How will you delete the OrdersTable from the database using SQL Injection?

Chicago'; drop table OrdersTable --
Delete table'blah'; OrdersTable --
EXEC; SELECT * OrdersTable > DROP --
cmdshell'; 'del c:\sql\mydb\OrdersTable' //
