Redis: grinning Alright!! Lesson switch! HckThon time!! Ready to crrack some codes, kid??
ChocolatePhoenix
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
Ok
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
Ok
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
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
Okay
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~
Here's the disguised Java code. Can you figure out what it does? `if i > 10: System.out.println"Hello!"`
ChocolatePhoenix
The code is obviously trying to check if a variable i is greater than 10, if so, then it will print "Hello!"
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
Thanks, but that was pretty obvious, you know~
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
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
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
Okay
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
ChocolatePhoenix
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
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!
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
Yes
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
Machine learning? That's awesome, but I have one question, why aren't we learning about cyber security?
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
Yes, that sounds good. When will the next lesson be?
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
I smile and end the session
The session ends, and ChocolatePhoenix goes home, feeling accomplished and eager for the next lesson.
ChocolatePhoenix
Closes laptop and begins doing other work
Meanwhile, over the next day, Redis works hard on creating an engaging and informative cyber security lesson for ChocolatePhoenix. It's almost done...
