How to Create an Engaging Engineering CTF Competition

Building Capture The Flag competitions and generating questions

About CTF

Capture The Flag, abbreviated as CTF, is a sport that originated in the West and is commonly seen in paintball and first-person shooter games today. The original concept involves teams competing to protect their own flag from being stolen while also trying to capture the flags of other teams. In the computer field, this translates to “attack and defense” where teams first identify their vulnerabilities to protect against intrusions, while simultaneously launching zero-latency attacks to score points by capturing from other teams.

The above describes a standard, or even “advanced,” way of conducting a CTF competition. However, running a CTF competition within a company comes with additional practical considerations:

1. The purpose of holding a CTF competition is not only to enhance technical skills but also to promote communication among engineers.
2. Engineers have different strengths, including Front-End, Back-End, APP, and DevOps; to encourage participation from everyone, the questions should not be too focused on a specific area (e.g., networking, PHP).
3. Teams should be balanced in terms of strengths and expertise across different domains.
4. The event should ideally last no more than an afternoon.
5. Organizing a CTF competition is a side project outside of primary work responsibilities, so there are limited resources and time available.

Considering these factors, rather than calling it a CTF competition, it might be better described as:

An activity for team-based puzzle-solving to accumulate flag points & promote communication among engineers

This is a beginner-level CTF competition!

Activity Goals

1. Enhance engineering technical skills.
2. Promote communication among engineers.
3. Inspire enthusiasm and sharpness in exploring new things.
4. Make it fun; doing boring things can be quite painful.

Points 3 and 4 are my own additions. My expectations for this activity go beyond practical aspects; I hope to enhance everyone’s enthusiasm for exploration and learning new things in an enjoyable way, just like in daily work. We shouldn’t just be code monkeys; we should find ways to break through and keep moving forward!

Competition Rules

1. Engineers will be grouped based on their expertise and strengths.
2. Competition duration: 90 minutes.
3. A total of 12 questions will be provided, with 3 opportunities to purchase hints at a score cost.
4. Hint purchase costs will decrease over time (the earlier you buy, the more expensive it is).
5. Each question has a base score + time score (the earlier you solve it, the more points you earn).
6. Once a team selects a question to answer, they will be locked into answering that question or any other already unlocked questions until the question is passed or the time limit expires. (This rule is in place because the main goal of the activity is to encourage team members to communicate and brainstorm together, rather than dividing the work of solving questions.)
7. The score for each question, hint cost, and lock time will vary based on the difficulty of the question.
8. Victory condition: The team with the highest accumulated score wins; if scores are tied, the time taken to solve questions will be compared.
9. The winning team receives $$.

How to Create It?

Once the activity rules and goals are clarified, the next key point is how to set up a CTF competition.

This section will be divided into two chapters: First, creating a system capable of conducting a CTF competition, Second, generating competition questions.

1. Creating a System for CTF Competitions

This part requires both front-end and back-end technical skills to implement; if you’re not familiar, you may need to ask other colleagues for help.

Front-end: Semantic UI

Back-end: PHP + JSON files for data storage.

Due to time constraints, the competition system will be built to be simple, stable, and quick. The front-end interface will directly utilize the Semantic UI framework; the back-end will be written in PHP without using a framework, and data will be stored in JSON files without a database. Keeping it simple reduces potential issues (for example, preventing someone from attacking the competition system to directly obtain answers).

Entry Page:

Starting from a fun concept, the entry page uses a reference from the BBC series Sherlock:

Mobile unlock code S H E R

These four input boxes are for entering the identification codes obtained by each team (4 digits). For example: Team 1 enters “1432”, Team 2 enters “8421”, to identify which team is answering the questions.

As for the identification codes for each team, I embedded a little joke; the codes are presented as follows:

Can you see the four-digit identification code? If not, try stepping back from the screen a bit.

…….

……………

…………………

………………………

…………………………….

………………………………….

……………………………. .

……………………….

………………. .

…………

…….

. .

Answer: The identification code for Team 1 is 8291.

After entering, you will enter the main page of the competition system - question list:

Displayed at the top: Team 1, remaining hint vouchers.

Middle question area: Question name, description, points awarded for passing, lock time, hint purchase, hint display.

Hovering the mouse will show time score and hint price.

Displayed at the bottom: Total current score.

Back-end and other logic: The question list page will use Ajax to request the current answering status from the back-end every second, with the back-end reading and recording the answering status in each team’s JSON file. When unlocking a question, the time will be recorded, and until the time is up, no other questions can be unlocked. The completion time, time score, and hint price will increase or decrease based on the time spent.

This is the general outline of the competition system, but the focus is not on the competition system itself, but on the questions!

Whether they are interesting, whether everyone can participate, whether they have logic, and whether they are novel… these are really challenging to come up with.

Let’s get to the main point!

2. Generating Competition Questions

First, let me introduce the five questions I came up with.

1. The Door to the Magic Academy

Question Description: You will receive a string of keys and need to use this key to decipher a spell, entering it in the spell input box; there is also a verification code field that needs to be filled out before submitting the answer.

Answer:

This question tests information security and encoding issues; it utilizes a platform encryption and decryption vulnerability interface. If all encryption and decryption on the website are done using the same method and the same key, we can exploit this weakness to unlock the encrypted content and obtain the original data!

You can see that the verification code part is ./image.php?token=AD0HbwdgVDw= which provides a decryption interface, so we can try using the encryption key from above:

This gives us the decrypted string: LiveALifeYouWillRemember.

Enter this into the spell input box to pass!

2. Take Me Back to Shanghai in 1937!

Question Description: You need to input a year/month/day to send to the back-end, allowing it to determine that it is the year 1937; the input range for the year (1947-2099) does not allow direct input of 1937.

Answer:

The main point of this question is not how to bypass front-end validation, as the back-end processes it and cannot be circumvented; this question primarily tests the 32-bit computer 2038 problem. Due to the 32-bit timestamp limitation, it can only display up to January 19, 2038, at 03:14:07; beyond that, it will overflow back to January 1, 1901. Therefore, by calculating forward, entering 2073-02-06 to 2074-02-05 will fall within the year 1937, and submitting a date within this range will succeed!

3. Clash of the Titans

Question Description: You need to find a way to receive a password reset email from a third party (an email you cannot log into) and complete the password reset for someone else.

Answer:

This question requires more sharpness. First, use your own email to request a password reset; the email we receive is as follows:

Your password reset link: http://ctf.zhgchg.li/10/reset.php?requestid=OTk= If this is not related to you, please disregard this email, thank you!

We can see that the password reset request is identified by the requestid parameter, and the value we received is OTk=, which looks like base64? Let’s give it a try:

base64 decode and encode

We find that the parameter value is 99. By repeating the password reset request, we get 100, so we can infer that the password reset requests are sequential numbers. The next number would be 101. Now, we can return to the original email we wanted to bypass and request a password reset; we can forge a password reset link and secretly reset someone else’s password.

Encoding 101 in Base64 gives us MTAx, and we can forge the URL: http://ctf.zhgchg.li/10/reset.php?requestid=MTAx. Enter any password and click the reset button to pass!

4. Master of Disguises

Question Description: You need to create 10 Gmail accounts (Gmail hosted accounts) to receive the answer emails.

Answer:

Of course, this question could be brute-forced, but company emails cannot be registered arbitrarily; unless you find 10 people to help you receive emails, you cannot answer.

The key to this question is Gmail accounts/Gmail hosted accounts. Since company emails are Gmail hosted accounts, they also have the characteristics of Gmail accounts: you can use “.” and “+” to create infinite variations of the email address. The “.” can be placed anywhere in the username, and “+” can be placed at the end followed by any number.

For example, if the main email is zhgchgli@gmail.com, then z.hgchgli@gmail.com, zh.gchgli@gmail.com, zhgchgli+1@gmail.com, zhgchgli+25@gmail.com… will all be delivered to zhgchgli@gmail.com. One email can create multiple identities!

This question serves as a reminder to filter out these characters when registering accounts to prevent malicious users from creating numerous fake accounts.

After receiving 10 emails, you can combine them to find the answer URL, and entering that URL will allow you to pass!

5. Time Machine

Question Description: Similar to question 3, you need to find a way to receive a verification code (4 digits) via SMS from a third party (an SMS you cannot receive) to log into someone else’s account.

Answer:

This question is less common and more difficult, primarily simulating a side-channel timing attack. The system login verification includes a complex algorithm, and there will be timing discrepancies when processing verification information (for example, entering one correct digit takes longer to process, while entering all wrong digits returns immediately). By observing these timing discrepancies, we start from 0000 and try one digit at a time. When we try 2000, we notice it takes one second, indicating the first digit is 2. Continuing with 2100 also takes one second, but 2200 takes longer, indicating a two-second delay… By continuing to test the third and fourth digits, we eventually arrive at the answer: 2256.

This question simulates such an attack, with the back-end processing using sleep to mimic a complex algorithm. Generally, such attacks are less encountered in web and app environments; on one hand, the information processing is not complex enough to show significant timing discrepancies, and on the other hand, network factors can influence the results, making it difficult to judge.

For more details on side-channel attacks, you can refer to this article:

> _The above are five questions I came up with; below, I will continue to introduce the remaining seven questions provided by my colleagues._

**1\. Sadako Appears**

![Sadako image sourced from the internet](/assets/729d7b6817a4/1*I4jlrpa3w-HmqCtuTY11ig.png)

Sadako image sourced from the internet

**Question Description:** The task is to input what Sadako wants to say in the dialogue box above to pass the level.

**Answer:**

This question tests whether you understand the concept that images can contain other information. The key lies in the original image:

![Sadako image sourced from the internet](/assets/729d7b6817a4/1*zMmNz4PsgipRaxIPhUhYcQ.png)

Sadako image sourced from the internet

This image has secretly compressed a text file inside it (for the actual method, please refer to: [How To Hide A ZIP File Inside An Image On Mac \[Quicktip\]](https://www.hongkiat.com/blog/hide-zip-image-mac/){:target="_blank"}; note the differences between Win/Mac).

So, we just need to simply unzip this image using Commone to obtain the passphrase:

![](/assets/729d7b6817a4/1*e6j1AJPcv_qROUX4xUsJHA.png)

![](/assets/729d7b6817a4/1*YVOGsdi1hS2OO6ctHc6dFg.png)

Input "YOUHAVENOIDEA" in the dialogue box to pass the level!

**Supplement:**

Regarding the part about hiding information in images, there is another method using "[Image Steganography](https://blog.trendmicro.com.tw/?p=12510){:target="_blank"}"

![[Image Steganography and Malware: Principles and Methods](https://blog.trendmicro.com.tw/?p=12510){:target="_blank"}](/assets/729d7b6817a4/1*WfSUbQXSjTOg28ZWsihMHg.png)

[Image Steganography and Malware: Principles and Methods](https://blog.trendmicro.com.tw/?p=12510){:target="_blank"}

In simple terms, it involves manipulating the color values of pixel codes to hide information, where the actual image changes but is indistinguishable to the naked eye.

This question anticipates that some may go in this direction, so I also embedded a steganography hint in the image. Those who take this path can receive a clue:

![[Steganography Online](https://stylesuxx.github.io/steganography/){:target="_blank"}](/assets/729d7b6817a4/1*POIFkyOYl3RdBWUAofw3PQ.png)

[Steganography Online](https://stylesuxx.github.io/steganography/){:target="_blank"}

Upload the image to an online steganography decoding tool to obtain the hint.

**2\. Caesar's Morse Code**

![Material image sourced from the internet](/assets/729d7b6817a4/1*PZz3sUOhaUNKRmNS_jY1RA.png)

Material image sourced from the internet

**Question Description:** Try to decipher the meaning contained in the provided Morse code (a sentence in English).

**Answer:**

This question is quite straightforward. The first step is to decode the Morse code into English letters: "`VYYXI DN HT GDAZ`"

![[Morse Code Translator](https://mathsking.net/morse.htm){:target="_blank"}](/assets/729d7b6817a4/1*venMZ3lkF-hYarWe9bMd6A.png)

[Morse Code Translator](https://mathsking.net/morse.htm){:target="_blank"}

Then, we perform a Caesar cipher decryption. When we try an offset of 5, we get a meaningful English sentence: "[addcn](https://www.addcn.com/){:target="_blank"} is my life," which is the answer!

![[Caesar Cipher Decryption Tool](http://ctf.ssleye.com/caesar.html){:target="_blank"}](/assets/729d7b6817a4/1*kTiosisv3i7Ib9v25AYftg.png)

**3\. What Do You Think It Is?**

From the beginning, we can tell that this is a base64 compressed image. By pasting the above encoding directly into the browser's address bar, we can obtain the URL where the answer is located. Once we enter the URL, we can proceed!

**4\. Breaking Through the Blockade**

**Problem Description:** Upon opening this problem, it directly displays the PHP code for the question. We need to find a way to bypass the judgment using GET parameters to execute the `setPassedCookie();` method inside the else statement.

Solution: This problem involves a commonly used but little-known PHP vulnerability, which is detailed below:

![[Summary of Common PHP Vulnerabilities in CTF](https://xz.aliyun.com/t/3085){:target="_blank"}](/assets/729d7b6817a4/1*iITV3WJTJHez1xRpul6uTA.png)

[Summary of Common PHP Vulnerabilities in CTF](https://xz.aliyun.com/t/3085){:target="_blank"}

The problem has been slightly modified, and the answer to this question is: `?m.id[] = admin`

**5\. The Test of Penetration, 6\. The Test of Penetration 2**

These two questions are basic entry-level XSS problems, so I won't elaborate further.

For this question, since I placed the answer on the frontend, I used a JS website that provides irreversible encryption: [https://www\.sojson\.com/jsobfuscator\.html](https://www.sojson.com/jsobfuscator.html){:target="_blank"}

(Although I'm not sure if it's true? Anyway, if there's a way to crack it, let's consider it passed!)

**7\. Moonlight Treasure Box**

This question is pulled from a puzzle-solving app, and I won't showcase it here.

### Summary

The competition system took about a week to build, and the questions took about three months to gradually piece together (it requires inspiration); the competition has successfully concluded, and the feedback received has been quite positive—"fun and enjoyable"; this was also my original intention, hoping everyone explores and brainstorms from a fun perspective. Therefore, regardless of the question titles (which are all movie-related) or the direction of the questions, there won't be anything too deep in engineering or calculations, as that would be too dull and uninteresting!

Additionally, here is the question response rate, which serves as a reference for difficulty:

![](/assets/729d7b6817a4/1*-ViR_TfrzhANOFymo1eVoA.png)

When I was creating the questions, my biggest fear was that they would be too easy and everyone would solve them quickly, or too difficult and everyone would get stuck—both situations are quite awkward.

The actual results of the questions in the competition (competition time: 90 minutes) met our expectations, just right! Not too difficult or too easy; the first-place team solved 9 questions, and even the last-place team solved 7 questions; very close, but due to time scoring and purchased hints, the final ranking was still determined!

> Surprisingly, no one managed to solve the door to the magic academy… QQ

This concludes the summary of the engineering CTF competition.
