Rule system

When Zhao Yi talked about the hacker's'too destructive power', Professor Liu just smiled, looking a bit like watching a child play with his new toy.

Most "little hackers" are like this.

When you use hacker software, or use tools to steal passwords and account numbers, you have a feeling of'very powerful', but in fact it is not a big deal at all.

Now that the domestic network has just been constructed, the security is far from high. It is a bit too much to describe the full range of vulnerabilities, but most users do not have network security knowledge, which is also an important cause of security problems.

For example, a family has just built a house and has no awareness of safety at all. Farm tools and chickens and ducks raised at home are simply placed outside the house at will. There is a small fence in the yard as a dividing line.

Outsiders can steal a lot of things as long as they cross the fence.

It sounds unbelievable, but this is the case, but for most users who are not security conscious, the information in the computer does not have any value.

Hackers, to put it bluntly, are people with good computer skills.

Zhao Yi is a genius of computer programming and algorithms. He has found loopholes in the fruit system and designed a very innovative "screening method", but he was only an 18-year-old high school student who discovered that he designed some destructive codes. I found it very interesting, and I started to worry about destructiveness.

These are all normal.

Professor Liu was knowledgeable and didn't care too much, but he looked at it carefully and asked Zhao Yi to help explain the function.

quickly.

Professor Liu couldn't laugh anymore.

"The routing monitor I designed for this piece of code can only be done if the routing security is not high..."

"This camouflage code is very interesting. It can penetrate through LAN games..."

"Automatically destroy the program. I use the control to call the bottom-level clear function of the target host to delete all programs with suffixes..."

"There is an invasion..."

"The disguised code can penetrate into the port, and the open access port of the general website can be disguised and penetrated..."

"Actually the most important thing is to pretend..."

Professor Liu was completely taken aback.

Not only was Professor Liu sitting next to him, but his student Xiao Zhicheng, who was also a PhD in computer science, stood behind the sofa and carefully looked at the content of the code. He couldn’t help but ask, “Are you sure you can Is it realized?"

"should be no problem."

Zhao Yi said, "I helped Zhengyang police perform security penetration, which is to help verify the security of their network. I successfully monitored their routing and tried a one-time camouflage Trojan horse program."

After reading a short piece of code, Professor Liu took a deep breath and said seriously, "I want to study it carefully."

It’s almost time for dinner in the afternoon. Seeing that Professor Liu didn’t mean to go out to eat, Zhao Yi and Xiao Zhicheng strolled to the restaurant outside and ordered a few dishes to be delivered to the house. He also asked Xiao Zhicheng about his accommodation and confirmed Liu. The professor might live there, so he bought a lot of toothbrushes and towels.

When I went back with my things, the sky became a little darker. A car came up from behind. The window was lowered and a head came out, "Zhao Yi!"

It is Lin Xudong.

Zhao Yi turned his head and saw Lin Xudong startled. He always felt that Lin Xudong's eyes were wrong, as if he was very unfriendly to him.

Lin Xudong stopped the car, opened the door and walked over.

Zhao Yi turned his head and looked at Xiao Zhicheng, feeling a little more settled, and asked with a smile on his face, "What's wrong, Uncle Lin?"

Lin Xudong also glanced at Xiao Zhicheng, took Zhao Yi and walked aside, and asked in a low voice, "Who is here in your house? Why do you let the police help you stare?"

"Staring?"

"Protection is protection. The wording is inappropriate."

Zhao Yidao, "Professor of the Academy of Sciences."

"Professor? It's from the Academy of Sciences?" Lin Xudong opened his mouth suddenly and asked with some surprise, "What are the professors of the Academy of Sciences doing at your house? Do you still know such a big man?"

Zhao Yi seemed to be serious and said jokingly, "I went to the capital to give a speech some time ago, Professor, I have seen a lot."

"I heard, you can! You can!" Lin Xudong said with a smile.

He knows what Zhao Yi has done. It seems to sound very powerful and powerful, and it has been reported in various media. However, it is difficult to connect a big figure at the professor level of the Academy of Sciences with this bastard who hooked up his precious girl. At the same time, he simply followed Zhao Yi's tone and asked, "Then tell me, the professor of the Academy of Sciences, what are you doing at your house?"

"Talk to me about scientific research."

"What kind of scientific research, let me be specific!" Lin Xudong seemed to want to expose Zhao Yi, and continued to ask.

Zhao Yi looked up at Lin Xudong and stared at his face with a scrutiny gaze. Then he sighed and said, "Okay. That's it. They are designing a smart product called'Smart Aniu', this'smart The main function of "Aniu" is to understand the beginning of all kinds of music and continue to sing along!"

"so smart?"

"Uncle Lin, I won't tell you anymore, I have to go back!" Zhao Yiliang showed what was in his hand and went back with Xiao Zhicheng.

Lin Xudong returned home.

Lin Xiaoqing walked out of the room and asked curiously, "Dad, do you know who is from Zhao Yi's house? I asked him and he said what professor it was."

Zhao Hongjuan also poked her head out of the room, "Yes, I just went shopping for groceries, and saw your two colleagues standing downstairs. What kind of person is that?"

"Professor of an Academy of Sciences."

Lin Xudong felt that he had room to play. "Zhao Yi said he was here to discuss scientific research. I asked him what he said to be a "smart cow" that can understand all kinds of music. I don't quite understand."

"Smart cow, listen to music?"

Lin Xiaoqing pondered over it a few times, and immediately recollected and said a word, "Play the piano to the cow?"

Lin Xudong was stunned.

Zhao Hongjuan couldn't help laughing'pouch'.

The whole family pondered over.

Lin Xudong flushed with anger, and turned around to put on shoes at the door, "This kid dares to scold me, I can't spare him!"

Zhao Hongjuan and Lin Xiaoqing laughed and grabbed them.

Zhao Hongjuan also said, "You said you didn't react at the time, so I was embarrassed to go to someone. Isn't that just playing the piano to the cow? Zhao Yi is a smart boy who talks about scientific research with the old professor. What do you always ask?"

"Playing the piano to Niu, this word is good and appropriate, come back and change your name, just call it Lin Xu Niu..."

Lin Xudong wanted to punch someone.

Lin Xiaoqing blinked, and suddenly she was a little worried about Zhao Yi. She picked up the phone and sent a message, "My dad sees it, please pay attention."

The information came back soon.

"Xia Lin, you can protect me!"

Lin Xiaoqing chuckled while looking at the phone, pursed her lips and said two words, "I hate it!"

...

Professor Liu has been studying the code.

The code designed by Zhao Yi is still a bit complicated, and it is not easy to understand it all in a short time. Professor Liu simply divided the code into several "functional modules" and marked them separately.

He looked at the code function carefully, the more he looked at it, the more interesting it became.

This camouflage and penetration function is really too powerful. It can be said that it can break through most of the safety nets. The existing security defense system is almost impossible to deal with this kind of penetration.

After Zhao Yi came back, Professor Liu discussed with him.

Not only discussing the ports through which the code can be penetrated, the information that can be intercepted, etc., but also divergent thinking, discussing what kind of functional programs can be hidden under the'disguised' code, and how to directly invade the target server attack.

This discussion is one hour.

After eating something at random, Zhao Yi wrote a code program with special functions according to what was discussed.

Professor Liu was also watching.

Originally, Professor Liu planned to write while pointing, but he found that he couldn't speak at all. During Zhao Yi's writing process, his fingers were almost non-stop, and he saw lines of code on the screen continue to increase without stopping at all. when.

Xiao Zhi came to see Chengdu.

Xiao Zhicheng was a bit unconvinced with Zhao Yi before. He was a PhD student in computer science. He felt that the level of a high school student must be limited. He had some luck when he came up with a new algorithm, but he suddenly thought of a'good idea'.

Now Xiao Zhicheng finds that he is wrong, not to mention the "screening method" or "hacking technique". As far as the ability to write code is concerned, three or four of them together are probably not opponents at all.

This speed?

Copying can't compare to it!

After Zhao Yi wrote the code, he started to run and debug it. He was going to use his own website. Professor Liu simply helped to make a website. "Use this website, an information network of the Academy of Sciences, and a subordinate website of our department. It doesn’t matter. Said I did it."

"No need to check, the open port is..."

Zhao Yi input separately.

After the program officially runs, he uses another computer to find a proxy IP to open the target website.

A prompt popped up on the webpage, "Is the XXX program loaded? From the website

"load!"

Several large blood-red characters appeared on the computer screen: "Warning: Your computer has a virus!"

"Success!"

Zhao Yi stood up happily and waved his hand very hard.

Professor Liu was also very happy.

Xiao Zhicheng and his assistant stood aside, staring blankly, feeling a bit scary.

So simple?

They are also computer professionals, and they are also very familiar with computer technology. They only know the open ports of the target website and run a program on their computer. Will users who visit the website get a virus?

Not a virus!

That is just a small animation program executed by calling the user's low-level functions.

But it's scary to think about it!

At this time, Zhao Yi's Penguin rang suddenly, and Zhou Ming sent a message, "Are you ready? It officially starts at nine o'clock!"

Zhao Yi looked at Professor Liu with questioning eyes.

Professor Liu replied in the past, "OK!"
