Villain’s Programming - Chapter 212

Episode 212: I think I made this, right?
Copycat accessed the 2CH security system following the passage created by Dojun.
Dojun was watching the scene in real time through the eyes of a copycat.
‘it’s okay!’
As Junyeop said, the open passage was becoming increasingly blocked. The light was gradually disappearing and the front was becoming blocked.
In some ways, it looked scary, but Dojun actually smiled.
‘No matter how hard you struggle, it’s only a bite away. Copycat! ‘CUT it out!’
The ability Copycat gained after reaching level 7 was ‘CUT’.
CUT is the ability to cut out part of a program. It was identical to the ‘Cut’ function that ordinary people often use to edit documents in Windows.
The copycat opened its mouth wide at Dojun’s command. The copycat’s mouth expanded ten times the size of its body and bit into the blocked light passage.
– Wajik!
Huge teeth marks were left in the world of the virtual program. The teeth marks completely destroyed the passage.
‘Isn’t it going to be difficult to recover at this level? Because part of the program was completely lost.’
A huge system was visible behind the broken passageway. It was a 2CH server.
‘Now all that’s left is to solidify this passage through hacking.’
Dojun returned to reality and contacted Dongjin.
[Dojun: Dongjin. How did you create the hacking tool?]
[Dongjin: Fortunately, I completed the first part. Junyeop, this guy’s skills are amazing, right? I was able to upgrade further thanks to this guy’s help.]
Dojun became more greedy for Junyeop.
[Dojun: Okay. Then try it right now. The passage has been cleared.]
It was Jun-yeop who answered Do-jun’s words.
[Junyeop: Really? I’ll try it right now.]
[Junyeop: Oh! Is it true? Crazy, crazy! How did you do this?]
[Dojun: You said it. It shows ability.]
[Junyeop: Oh my god, the defense system is strange? I completely enjoyed it. This is not the level of creating a passage!]
Junyeop made a fuss in the chat room and asked Dojun.
[Junyeop: I will call you uncle, no, sir, so please tell me how you did it.]
[Dojun: It’s late. There are already people calling me Sabu.]
[Junyeop: Who are you? does not matter. I can do better than that person!]
Dojun snorted and posted a picture of ‘Minmei’ in the chat room.
[Junyeop: Ugh. Who is this pretty sister again? It’s totally my style. I think she resembles the actress I saw in Sex World, right?]
[Dojun: Why do you look at the color system?]
[Junyeop: Ah, I don’t know! Man, that’s not the point. I think I’m in love. Where does this person live? Do you work at Black Cat?]
The more Dojun talked to Junyeop, the more he became distracted. It was a tense situation, but the tension was relieved.
‘This isn’t that bad.’
[Dojun: No, Minmei is Chinese.]
[Junyeop: China? are you okay. Where are the borders in love?]
Dojun laughed heartily.
‘A guy who just blushes and can’t say a word in front of women flies around in chat rooms.’
[Dongjun: CEO, I have just sent you the hacking file by email. And now, let’s hack it here too.]
[Dojun: I’ll wait. Please contact me immediately when the results come out.]
* * *
Hajime breathed a big sigh of relief.
‘thank god. I replaced it with the system file Wilson gave me, and the system is now stable again.’
Of course it would take time, but it didn’t matter.
The important thing was to prevent a large-scale attack tomorrow.
Hajime suddenly became curious about a person named ‘Wilson’.
‘Who on earth is Wilson? Is he the head of a large underground hacker organization? What country is he from? USA? russia?’
The more I thought about it, the more amazing his abilities became. Not only was it enough to create a hacking and defense program of this level, but it was also perfect for responding to emergency situations.
‘If it’s a place like this, shouldn’t we continue the relationship even if we have to pay money? ‘Why did my father tell me to break off the relationship?’
Of course, it cost a lot, but I thought it was cheap compared to the end result.
‘hmm. At this rate, restoration will be completed before midnight. ‘We will be able to completely prevent Korea’s attack tomorrow.’
Hajime clenched his fists.
‘And you can’t just block it. Next we’ll launch an all-out attack. You said you recruited 100,000 people in Korea, right? We’re going to attack with 200,000 or 300,000 people.’
Hajime thought that his great-grandfather’s blood flowed in him.
‘I can’t believe attacking Korea feels this good!’
Hajime waited for the day to attack as soon as possible.
It was like 9 o’clock. I received a call from Kentaro.
‘huh? What’s going on at this hour? I told you all about the start of recovery earlier.’
Hajime answered the phone.
– Hajime, you’re in big trouble. 2ch contacted me and said that the defense system was completely disabled.
“yes? Are you having trouble? “Has it been breached again?”
– no. It didn’t break through.
“Then?”
– It is said that the defense system program given by Hajime is not working. Of course, there are some parts that work, but many are said to be broken.
* * *
Dojun was very surprised when he heard the report on Dongjin’s status.
‘You’re really crazy! Even though it’s broken to this extent, it still works to some extent?’
I quickly realized why.
‘The capacity of the security system was 100MB. However, the only size the copycat could cut was 1MB.’
The size of the security system executable file that Dojun checked was 10M. However, when you run the executable file, it is loaded into memory and its capacity becomes 100MB.
‘I think it was actually great to be able to stop the operation with just 1MB.’
It was all thanks to Junyeop that we were able to do this. It was Jun-yeop who hit the weak spot.
‘But why hasn’t Dongjin contacted me like this?’
Do-jun asked Dong-jin to hack it and tell him the results. But even after 20 minutes, there was no news.
‘What’s going on? No, if something had happened, I would have contacted you right away.’
Dojun thought about just waiting, but then he suddenly remembered that Dongjin had sent him a hacking program by email.
Dojun immediately opened his mailbox and downloaded the ‘DT-04’ version.
Dojun grinned.
‘Why wait? I have a way to know whether DT-04 will be successful or not.’
Dojun called Copycat.
‘Copycat! ‘Try this!’
Although it is used more for hacking these days, the original ability of a copycat was to copy a program and check its success.
The copycat opened its mouth wide and swallowed ‘DT-04’.
Dojun sighed.
‘what? 50%? why?’
He had completely cleared the road. Of course, he had to succeed at hacking.
‘Isn’t there something wrong with the DDoS program because it was made in a hurry?’
It was then. A message was posted in the chat room.
[Junyeop: Mister. [There was a big problem.]
[Dojun: What?]
[Junyeop: The Japanese are rebooting the security system. Sequentially. I think we will soon reboot the system we breached.]
[Dojun: What?]
Dojun was surprised. And only then did Dojun realize why the success rate of the DDoS program was 50%.
‘If I reboot the system, everything I’ve done so far will be useless!’
The ‘passage’ opened by Jun-yeop and the program data that Do-jun ‘cut’ through copycat were all in ‘memory’.
However, when the system is rebooted, all memory is initialized and the security program is loaded into the memory again.
‘then… Everything I’ve done so far is useless!’
In fact, servers that are in service usually do not reboot. When absolutely necessary, it is announced in advance under the name of regular inspection, and there has never been a case where it was done so suddenly.
‘But now Korea and Japan are in a cyber war. You can do whatever you want. ‘How do I stop this?’
[Junyeop: Mister, can you enter the program again? Just like a little while ago.]
[Dojun: No. it’s hard.]
The size that Copycat could cut at one time was 1MB. But since it was already used, I had to wait a long time.
[Junyeop: Ah! It’s a big deal! If this happens, there is no way to break through again.]
Dojun grabbed his head.
‘Is there no way? doesn’t exist. Time has to pass. I wonder if the copycat levels up.’
For a moment, Dojun’s eyes sparkled.
‘Level up?’
Copycat had not been able to level up for a while.
‘I’ve been steadily accumulating experience. But I couldn’t level up. I almost gave up, but if you think about it the other way around, doesn’t that mean you’re close to leveling up?’
Dojun thought of a program that would greatly increase Copycat’s experience.
‘AMD Graphics Driver!’
Dojun went to the AMD site and downloaded the graphics driver that he had developed with an enhanced ‘mining’ function.
Dojun immediately had the copycat swallow the ‘AMD graphics driver’.
Dojun clenched his fists.
‘it’s okay!’
Now that all of Copycat’s functions have been reset, I can cut again right away.
That wasn’t all. The abilities of the existing copycat have been upgraded.
Dojun opened his mouth as he read the message that appeared.
‘How cool is this? So, from now on, you can hack the cell phone of someone 1km away, right? And the CUT capacity has increased to 10MB! ‘It’s increased 10 times!’
It seemed like this would be enough to completely neutralize the program.
‘But if I reboot the system again, I can’t stop it… … .’
It was time for Dojun to worry. Another level up message came to mind.
Dojun’s eyes widened.
‘what? Reverse engineering?’
Reverse engineering is the process of analyzing ‘data placed on memory’ in reverse and inferring the actual source.
‘It’s a very difficult field, but it’s an attractive field. ‘It’s the ultimate technique that steals other people’s techniques.’
Dojun looked at the ‘copycat’ yawning in front of him.
‘This guy has reached level 8 and has almost completed his final evolution. You have become a copycat in the truest sense of the word!’
Level 8 was like this, and Do-jun was almost afraid of what abilities would appear when he reached level 9.
‘Wait, then what? Could this be used? What if a copycat reverse-engineers the data obtained through CUT?
Dojun’s eyes widened. This was because the ‘security system’ file source could be obtained at that moment.
‘It’s crazy. it’s crazy! As long as you get the source code, it doesn’t matter whether you reboot the system or not!’
Dojun stroked the copycat’s head once and then spoke.
‘Copycat, do you remember that road from earlier? This time, do not CUT, but COPY&PASTE.’
The purpose this time was not to destroy the security system. To obtain the source, I did COPY&PASTE.
[Meow!]
The copycat disappeared and appeared before Dojun’s eyes a moment later. The copycat’s stomach was bulging and protruding.
‘I swallowed 10M worth of data, so I’m like this!’
Dojun said, pointing to the visual studio on his laptop.
‘PASTE there. Reverse engineering at the same time!’
[Meow!]
The copycat opened its mouth. Then, countless 0s and 1s poured into the laptop.
The 0s and 1s entered into Visual Studio began to turn into alphabets. Dojun’s eyes widened as he saw that.
‘I can’t believe this is really happening!’
It was just like magic.
Dojun looked excited as he looked at the program source displayed on the monitor.
Although the 10M in memory was converted to source, it was sufficient to analyze the core logic.
‘If you analyze this, you can find loopholes!’
When programmers code, they code assuming limitations.
For example, in a game, the inventory limit is 100, or a user can only create 3 characters, etc., etc. These restrictions are basically enforced when coding.
‘And problems arise when those restrictions are exceeded.’
Of course, a good programmer codes so that no problems occur even if data exceeds the limit.
‘But as long as you’re human, you can’t do that everywhere. There are definitely some parts that aren’t like that.’
Dojun looked at the source code displayed in Visual Studio and looked at it again. But the more I looked, the more strange it felt.
‘what? Why is this code so familiar?’
Dojun tilted his head.
‘this… I think it’s similar to GUARD CAT’s scrubbing program. Of course, it seems to be much more complex and more advanced than that.’
Dojun, who thought it was strange, immediately contacted Annie from GUARD CAT.
“animated film.”
– Yes, boss.
“I’ll send you some sauce. “Check this out.”
– Boss, if it’s not urgent, can we do it later? I’m currently having a meeting with the staff to fix the GUARD CAT opening.
Normally, Dojun would have respected Annie’s words. But this was an emergency.
“animated film. By any chance, has the GUARD CAT source been leaked?”
Annie shouted in surprise.
– Our sauce? Absolutely not.
“Can you guarantee?”
– yes! I don’t know anything else. Source management is probably the best in the world.
These were the words of Annie, a genius hacker. All routes accessing the source were blocked.
Dojun, who knew that, would have believed it without a second thought.
– But boss, why all of a sudden?
“hmm. Annie, I will send you some sauce. Check this out. “It’s urgent, so please check right away.”
Dojun sent the sauce to Annie by email. It was less than 10 minutes later that I got a call from Annie again.
– Boss, what is this? Where on earth did this come from?
“Annie, calm down and speak slowly. “Is this GUARD CAT sauce?”
– That’s true… I don’t think so. Honestly, I don’t know what it is.
Dojun asked, tilting his head.
“What are you talking about? GUARD CAT The source may or may not be correct?”
– First of all, this sauce is exactly what I made. Because the signatures I leave behind in the sauce are all over the place.
“Really?”
– however… I’ve never made a sauce like this before. No, to be more precise, I can see what I made, but it looks like someone upgraded it. But the problem is… That someone seems to be me.
Dojun did not understand Annie’s words.
“So, to summarize… “You didn’t make it, but it looks like you made it?”
– yes. I know this sounds crazy, but I guess it is.
“ha!”
Dojun grabbed the back of his neck with his hand. He wondered if he could find a solution, but an unexpected problem arose.
– Boss, where did you get this sauce?
Dojun explained what had happened so far.
– So, this is the security system source used by 2CH?
“that’s right. Don’t ask me how I got the source. “It’s complicated to explain.”
– all right. Then I have something to tell the boss.
“no way? “You’re not saying you need to go to the hospital and get diagnosed, are you?”
Annie said with a smile on the phone.
– no. Two pieces of good news.
“Good news? say it.”
– First, within this source, there is logic to solve the problems of our GUARD CAT. If you apply this, you will have a perfect GUARD CAT security system by tomorrow.
Dojun clenched his fists. This was exactly the answer Dojun wanted.
“second is?”
– I think I know the weaknesses of the system you just sent me.
