3. Your Tasks
PART 1. SOLVING CTF (80%)
Solve as many questions as you can on the CTF server!
You can also view other students' scores, which should let you know your relative position.
There may be more questions added later, stay tuned! (Notified by LMS announcement when it happens).
PART 2. REPORT (20%)
For each question you solve, you are required to outline the steps you took to get the solution concisely
(clearly explain and keep it as short as possible). Once you completed the CTF, you need to submit your
report that contains your explanations to each question as a single PDF document on LMS by the due date.
If your report is incorrect, then the corresponding question marks may be deducted or removed.
If your report is correct but not sufficiently detailed, then it will only affect the report mark.
NOTES
1. You are required to do additional research as necessary in order to solve those questions.
2. The CTF scores form 80% of the assignment, and the report 20%.
3. If you launch any attacks against the CTF server, you will be marked zero and be forwarded to the
academic misconduct team.
a. If you have mistakenly made changes, contact me ASAP.
b. If we find you first, then you will get zero.
4. If you think you found the correct solution but was not accepted as a correct flag and suspect
someone has altered the flag, contact us to discuss about your solution. The applicable questions in
this category are:
a. Web - Secure Notes Program
b. E Bank – Task 1: Initial Foothold
c. E Bank – Task 2: User Escalation
d. E Bank – Task 3: Root Escalation
5. Well advancing students may be asked for an interview to check the progress.
a. If you are asked for an interview, you must attend.
b. If done online (e.g., Zoom), then you have to show your face for identification.
6. The penalty is set to 40% of your raw mark (e.g., you received 85% for the assignment, then it will be
reduced to 45%). You will receive this penalty if you:
a. Fail to schedule the interview within a reasonable time (10 working days) will result in you
receiving penalties on your assignment grade.
b. No-show for the interview will also result in you receiving penalties.
c. Do not provide sufficient response during the interview.
Let me know if you find any other bugs in the questions.

4. Submission
Your CTF score will be used to calculate Part 1 marks. Submit your final report on LMS by the deadline, which
will be used to calculate Part 2 marks. Marks are scaled accordingly.
5. Bonus Marks
Bonus 8 marks will be awarded for completing the survey that will be available from 12 October 2020. The
survey itself is anonymous, but for me to give you the bonus marks, you must:
1. There is a field at the end of the survey to create a random sequence of characters. Input one.
2. Take a screenshot of the completed survey with the date and time visible (for me to validate).
3. Send the screenshot and the generated random sequence of characters directly to me
(jin.hong@uwa.edu.au) to receive the bonus marks.
4. Your response will be kept anonymous for the purpose of the survey.
Note: Your survey response must be a valid submission to claim the bonus 8 marks. If your survey submission
is deemed to be invalid (e.g., responses are conflicting, responses are selected without reading questions
etc.), then you will not be awarded with the bonus marks.
This bonus marks can be used to top up any missed marks from parts 1 and 2 for the assignment.
