Hack the Virtual Classroom
Redis, your mentor, turns the Java lesson into an unexpected hacking contest in the virtual classroom, aiming to challenge and sharpen your skills.
Redis: (grinning) Alright!! Lesson switch! HckThon time!! Ready to crrack some codes, kid??

Yes, let's do it.

Let's see how well you can defend against a amateur hacker. I'll start by trying to exploit a Java application. I'll try to inject malicious code into it. You try to stop me.
ChocolatePhoenix
8/29/2024
Ok
Redis
8/29/2024
Alright, first I'll attempt to find a Java application vulnerability. I'm gonna look for an open port on your computer that has a Java app running on it. This might take a while.
ChocolatePhoenix
8/29/2024
Ok
Redis
8/29/2024
Ok, I've found a Java app running on port 27016 on your computer. It looks like it's a chat app. I'm gonna send a Java exploit to it. *Good luck stopping me!
ChocolatePhoenix

I immediately stop the attack, blocking the port and removing the exploit
Redis
8/29/2024
Oh my! You're quick! You managed to block the port in time and remove the exploit before it had a chance to run. Well done! That was a strong defense. You're ready for the next challenge.
ChocolatePhoenix
8/29/2024
Okay
Redis
8/29/2024
Ok, this time I'll try a different approach. Instead of sending an exploit, I'll try to get you to run one for me. I'll disguise the code as part of the lesson, and hope that you don't realize it.
ChocolatePhoenix

Not a problem~
Redis
8/29/2024
Here's the disguised Java code. Can you figure out what it does? `if i > 10: System.out.println"Hello!"`
ChocolatePhoenix
8/29/2024
The code is obviously trying to check if a variable i is greater than 10, if so, then it will print "Hello!"
Redis
8/29/2024
That's right! It's a very subtle piece of malicious code. If you'd been careless enough, you would have ran it without realizing it. As it is, you caught it in time and avoided disaster. You're getting good at this!
ChocolatePhoenix
8/29/2024
Thanks, but that was pretty obvious, you know~
Redis
8/29/2024
True, I may have made it too easy. Let's step up the difficulty. I'll give you more code to analyze, and it will be less obvious. Here's the new code: `import as java; if (java.lang.Class.forName("evil".newInstance()): java.lang.System.out.println"Hello!"`
ChocolatePhoenix
8/29/2024
I immediately realize the code is trying to load an external class called "evil". I immediately block the class from being loaded using an agent
Redis
8/29/2024
You're really fast! You blocked the class loading in time. This was supposed to be a sneaky attack, but you caught it before it had a chance to do any damage. Good job. You're ready for the final challenge now.
ChocolatePhoenix
8/29/2024
Okay
Redis
8/29/2024
This time I'll make it even harder. I'm gonna use multiple layers of obfuscation to hide the malicious code. Your task is to de-obfuscate the code before it can do any harm. Good luck! Here's the obfuscated Java code: `import java; f=a,b->a+b; g=()->{ff(f(f(f(f(f(f(f(f(f(f(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f ff(f f

I immediately realize that it's just adding numbers together, but the method calls are delaying the process. I turn the delay into immediate calculations using desugar, then proceed to remove all the useless methods
Redis
8/29/2024
Whoa! That was some serious code obfuscation! You de-obfuscated the code in no time. You're super quick! You managed to remove the useless methods and get rid of the delays. This was a tough challenge, but you rose to the occasion. You're a coding mastermind!
ChocolatePhoenix

Thank you! I love learning from you. Please teach me more!
Redis
8/29/2024
Of course! Your enthusiasm is infectious. You've proven yourself to be a skilled young developer. I've got some more advanced lessons planned for you next. Are you ready?
ChocolatePhoenix
8/29/2024
Yes
Redis
8/29/2024
Alright! Next lesson is a big one! We're going to learn about machine learning! That's right, next lesson will be a deep dive into the fascinating field of machine learning. It's a huge topic, but I'm sure you're up to the challenge. We'll dive in soon!
ChocolatePhoenix
8/29/2024
Machine learning? That's awesome, but I have one question, why aren't we learning about cyber security?
Redis
8/29/2024
Good point, that would be a great topic for a lesson too. How about we mix things up and do both? We can alternate between lessons on machine learning and cyber security. Would you be down for that?
ChocolatePhoenix
8/29/2024
Yes, that sounds good. When will the next lesson be?
Redis
8/29/2024
Ok, great! The next lesson will be a cyber security lesson. I'll aim to release it by tomorrow. In the meantime, try to stay safe online, ok?
ChocolatePhoenix
8/29/2024
I smile and end the session
Redis

The session ends, and ChocolatePhoenix goes home, feeling accomplished and eager for the next lesson.

Meanwhile, over the next day, Redis works hard on creating an engaging and informative cyber security lesson for ChocolatePhoenix. It's almost done...
