The system is the king of the counterattack master

Honestly, he worked as a low-level employee in New World Company for five days. Han Xiaodong began to feel a little restless. The three-dimensional attack of the white pigeons on the Ark was in full swing. In five days, the four bases of the Ark were destroyed, and great achievements were made. Vulgar record.

But he has made no progress at all. After K's research, apart from network security, the company's defense against other forms of sniffing can be described as an iron bucket.

There are not only detectors, but also countermeasures. There is no way to conduct any form of detection, even traditional monitoring.

Now that there is nothing wrong with this company, Han Xiaodong would not believe it even if he was beaten to death. The problem is that he knows that this company has a deep trick, but he can't do anything about it, because the location of the server is where they There is no way to find it.

"This is not a way at all. This company has four floors, and my authority can only be used on two of them. I can't go up to the upper two floors. I can't really be a red card employee here, right? "Han Xiaodong sat at his desk, staring at the data on the computer, complaining non-stop in his heart.

"I analyzed the security system of this building, and I regret to tell you that even with a red card, you can only go up to the third floor, and you still have no permission on the top floor.

So, I suspect that the real data is stored somewhere on the fourth floor. I have no problem with you wanting to be promoted here, but I don't know if Dongmenshe can wait. "

K has obviously locked on the target, but judging from the current situation, this target cannot be achieved by normal means at all.

"It seems that we have to find a way." Han Xiaodong had a headache for a while, and he didn't want to cause this trouble for himself. After all, sneaking into this kind of work is very dangerous, and it is easy to startle the snake if you are not careful.

"Hey, Tony, help me." Han Xiaodong was thinking about what to do when someone called him suddenly. Tony was his alias. When he turned around, it was Jeff.

"Hey, Jeff, what's the matter?" Han Xiaodong stood up while answering. He was used to being called to do chores temporarily these days, so he was not surprised at all.

But this time Jeff didn't tell him what to do, but just waved his hand and told him to go to his office.

After entering the office and sitting down, Jeff handed a notebook in front of Han Xiaodong: "Our network service provider recently provided a new version of the firewall, saying that it can improve the company's security level. You know, the current attack methods are upgraded very quickly. Come on, we have to keep up too, how about you take a look at this version?"

Han Xiaodong turned the computer to his side, and found that it was actually the source code of a security program upgrade package. He quickly glanced at it, and couldn't help laughing secretly. This upgrade package seemed to improve the network security environment, but the real core The content is actually aimed at the security hole that K attacked two days ago.

With an idea in mind, Han Xiaodong was about to push the computer back to Jeff, but was stopped by K: "Wait, this is not the version provided by some network service provider."

Han Xiaodong's hands froze, and he straightened the notebook again, looked at the codes carefully, and asked puzzledly, "Is there any problem?"

"The few security patches here were written by the three old employees across from you, but what's interesting is that there is no connection between what they wrote before. Now they are packaged into one program, which is impossible Things, unless someone gave them a framework before and asked them to write things according to the template. Or someone unified their code with a fixed framework. If you use your technology, the second possible difficulty is nothing to do with rewriting difference, so I think the first possibility is a little higher.”

K's explanation sounds cloudy and cloudy. Although Han Xiaodong has studied the program, he still doesn't understand K's words, or he hasn't studied it so deeply.

"Can you make it clearer? I'm completely confused by you." Han Xiaodong stared at the computer screen, but the questions in his mind were still confused.

"To make an inconspicuous analogy, it's as if there are three people dividing paragraphs and copying different parts of the same text. In theory, even if they copy correctly, the handwriting will never be the same.

But the current situation is that the three of them copied different parts separately, and the copied results are seamless, not only the fonts are the same, but even the typos are the same.

This can only prove one problem—someone gave them a certain template in advance, so that they must write according to a fixed font template, or someone has a means to convert three different fonts into the same font for presentation . "

K tried to explain the situation with the simplest example, but Han Xiaodong still half understood.

"But what does this have to do with me? Maybe there is someone who can do this, or maybe they are a project team."

Han Xiaodong raised his own question. He didn't think it was worth noting. After all, he didn't come here to study program codes.

"The key is that this way of code integration is simply not something humans can do, and every programmer has his own habits.

Just like what I just said about copying texts, it is impossible for people to have the same fonts, unless those three people are masters of imitating other people's fonts.

Or someone can unify the fonts of the three of them through post-processing.This technology is not human technology. "

K's final conclusion finally made Han Xiaodong understand what he meant.

He slowly raised his head and looked at Jeff who was sitting in front of him. This version of the software was not provided by a security company, and the three programmers did not receive any special training. The only one who may have problems now is this Jeff. Supervisor.

"What? Is there any problem?" Seeing that Han Xiaodong looked at him in the wrong way, Jeff immediately stood up and wanted to come over to have a look.

"Ah, no, it's nothing." Han Xiaodong quickly pushed the notebook back: "It's very well done. The loophole I used a few days ago was patched so quickly. It's really amazing."

"Oh, that's not a compliment." Jeff said with some pride: "You have to know, our network security department is not a freelancer, this is already very slow.

In fact, we asked them to deal with that vulnerability that day, but the official patch is only released now. After all, we paid for it, so we can't let them idle. "

Jeff was obviously very satisfied with Han Xiaodong's performance, he closed the notebook, his eyes were full of complacency.

For his acting skills, Han Xiaodong is also convinced. This guy really has a way of pretending to be stupid. If K is not mistaken, then the security company Jeff is talking about is probably himself.

"That's right." Seeing that Han Xiaodong didn't react much, Jeff immediately handed over a piece of printing paper:

"I have a job I want to assign to you recently. It's a small program. This is a demand. You should be able to finish it in two days, right?"
