Section III: Task 2
You should have the following parts:
z Briefly describe the functionality of LC4.
z Describe the strategy you used to find each password (like what attacks, dics you used).
z List the passwords you have gotten.
Section IV: Questions
You should answer the following questions related to this project:
z What does SYSKEYED mean?
z Search the internet to find a program that could have been used to decrypt the SAM file and
save it as a PWDUMP file for LC4 to crack. What is the name of the program you found
and what does it do?
z If you weren’t the administrator, how could you retrieve a copy of the SAM file? You’ll
have to do some reading/exploring to find out (hint: One way involves checking to see if the
system has been secured after the backup process).
z Explain the differences between brute force, dictionary, and hybrid modes and what the
relative advantages/disadvantages of each are?
Section IV: Experiment Log
This part should describe your activities in this project.
z Clearly state the responsibility of each group member. If possible, give a table to tell who
did which task, who collected information of which device, who wrote which part of the
report, who coordinated the group work activities, etc.
z Give a log of your group activity, such as what you did on which day, and how many people
attend.
