Q11.

What is the initial task to be performed to locate the key-generation algorithm within the crackme?

Look for the code that reads the contents of the two edit boxes into which you're typing the username and serial number

Look for the dialog box creation APIs in the program's initialization code

Look for references to GetDlgItemTextA or GetDlgItemTextW

Open the Find References to Import window

Discuss

Answer: (a).Look for the code that reads the contents of the two edit boxes into which you're typing the username and serial number Explanation:The initial task to be performed to locate the key-generation algorithm within the crackme is to look for the code that reads the contents of the two edit boxes into which you're typing the username and serial number.

Q12.

What is the method used to create keygen programs?

Reverse engineering copy protection products

Purchasing keygen programs from developers

Developing keygen programs from scratch

None of the above

Discuss

Answer: (a).Reverse engineering copy protection products Explanation:The method used to create keygen programs is to reverse engineer copy protection products.

Q13.

What is the advantage of ripping key-generation algorithms from copy protection products?

It requires a deep understanding of the algorithm

It is a difficult and time-consuming process

It is an easy and effective method for creating keygen programs

It requires a large team of developers

Discuss

Answer: (c).It is an easy and effective method for creating keygen programs Explanation:The advantage of ripping key-generation algorithms from copy protection products is that it is an easy and effective method for creating keygen programs.

Q14.

What is the purpose of the Defender crackme?

To teach basic protection concepts

To demonstrate powerful protection techniques

To show how to create a keygen program

To introduce the concept of serial numbers

Discuss

Answer: (b).To demonstrate powerful protection techniques Explanation:Defender was specifically created to demonstrate powerful protection techniques that are similar to what you would find in real-world, commercial protection technologies.

Q15.

What operating systems can Defender run on?

Windows 98 and Windows Me

Windows XP, Windows Server 2003, Windows 2000, and Windows NT 4.0

Only NT-based Windows systems

All currently available Windows systems

Discuss

Answer: (b).Windows XP, Windows Server 2003, Windows 2000, and Windows NT 4.0 Explanation:Defender runs on all currently available NT-based systems, including Windows XP, Windows Server 2003, Windows 2000, and Windows NT 4.0, but it will not run on non-NT-based systems such as Windows 98 or Windows Me.

Q16.

Is it easy to crack Defender?

Yes

May be Yes or No

Can't say

Discuss

Answer: (b).No Explanation:If you’ve never confronted a serious protection technology before Defender, it might seem impossible to crack. It is not; all it takes is a lot of knowledge and a lot of patience.

Q17.

What is Defender?

A crackme

A protection technology

A console-mode application

A DOS program

Discuss

Answer: (c).A console-mode application Explanation:Defender is a console-mode application.

Q18.

What is the purpose of running Defender in a Command Prompt window?

It allows the program to communicate with the user using a simple text window.

It enables the program to run on non-NT-based systems.

It simplifies the program by avoiding the Windows GUI APIs.

It allows the user to enter bogus values.

Discuss

Answer: (a).It allows the program to communicate with the user using a simple text window. Explanation:Defender is a console-mode application that communicates with the user using a simple text window, and that it should generally be run from a Command Prompt window.

Q19.

What happens when you enter a bogus username and serial number into Defender?

Defender reports that you have a bad serial number.

Defender terminates with an error message.

Defender accepts the bogus values and allows you to continue.

Defender crashes.

Discuss

Answer: (a).Defender reports that you have a bad serial number. Explanation:When you enter bogus values into Defender, it reports that you have a bad serial number.

Q20.

Why is it important to know what the failure message looks like when cracking?

So that you can identify where in the executable the message is located.

So that you can better understand the protection technology being used.

So that you can create a keygen program that produces the correct failure message.

So that you can avoid triggering the protection mechanism by providing the correct input values.

Discuss

Answer: (a).So that you can identify where in the executable the message is located. Explanation:One good reason to always enter bogus values into the program when cracking is so that you at least know what the failure message looks like, and that you should be able to find this message somewhere in the executable.
