When Zhao Yi said that hackers' things were 'too destructive', Professor Liu just smiled, and his eyes were a bit like watching a child play with his new toy.

That's the case with most of the 'little hackers'.

When you use any hacking software, or use tools to steal any passwords and accounts, you have a feeling of 'amazing', but it's not a big deal at all.

Now that the domestic network has just been built, the security is far from being very high, and it is a bit too much to describe it with a lot of vulnerabilities, but most users do not have network security knowledge, which is also an important reason for security problems.

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

Outsiders can steal a lot of things just by stepping over the fence.

It may sound incredible, but it's true, it's just that most users who are not security conscious don't have much value in the information on their computers.

A hacker, to put it bluntly, is a person with good computer skills.

Zhao Yi is a genius in computer programming and algorithms, he has found the loopholes in the fruit system and designed a very innovative 'screening method', but he is only an eighteen-year-old high school student, and he finds it very interesting to design some destructive code, and he begins to worry a little about destructiveness.

These are all normal.

Professor Liu didn't care too much about being well-informed, but he still looked at it carefully, while asking Zhao Yi to help explain the function.

Soon.

Professor Liu couldn't laugh anymore.

"The route listener I designed in this code can only be ...... if the route security is not high."

"This camouflage code is very interesting, and it can penetrate ...... through LAN games"

"Auto-destroy program, I use the underlying purge function of the control call target host to delete all the programs with the suffix......"

"And the invasion ......"

"The disguised code can be used to penetrate the port, and the access port opened by the general website can be disguised to infiltrate the ......"

"Actually, the main thing is to disguise ......"

Professor Liu was completely stunned.

Not only Professor Liu, who was sitting next to him, but also Xiao Zhicheng, a student he led, who was also a doctor of computer science, all stood behind the sofa and looked at the content of the code carefully, and couldn't help but ask, "Are you sure you can do it?"

"It should be fine. ”

Zhao Yi said, "I helped Zhengyang police do security infiltration, that is, to help test the security of their network, I successfully listened to their routes, and also tried a one-time camouflage Trojan program." ”

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

It was almost time to eat in the afternoon, seeing that Professor Liu had no intention of going out to eat, Zhao Yi simply walked with Xiao Zhicheng to the restaurant outside, ordered a few dishes and sent them to his home, he also asked Xiao Zhicheng about accommodation, and determined that Professor Liu could stay, so he went to buy a lot of toothbrushes, towels and the like.

When I went back with my things, it was getting a little dark, and a car caught up from behind, and the window was lowered and my head poked out, "Zhao Yi!"

It's Lin Xudong.

Zhao Yi turned his head and was startled when he saw Lin Xudong, he always felt that Lin Xudong's eyes were wrong, and he seemed to be very unfriendly to himself.

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

Zhao Yi turned his head to look at Xiao Zhicheng, felt a little more at ease in his heart, and asked with a smile on his face, "What's wrong, Uncle Lin?"

Lin Xudong also glanced at Xiao Zhicheng, pulled Zhao Yi to the side, and asked in a low voice, "Who is in your house?"

"Staring?"

"Protection, it's protection, it's a misnomer. ”

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

"Professor, or from the Academy of Sciences?" Lin Xudong suddenly opened his mouth and asked with some surprise, "What are the professors of the Academy of Sciences doing at your house?

Zhao Yi seemed to be serious, and said jokingly, "I went to the capital to give a lecture some time ago, professor, I've seen a lot." ”

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

He knew what Zhao Yi had researched, it seemed to sound very powerful, very powerful, and it was reported by various media, but it was difficult to associate the professor-level big man of the Academy of Sciences with this bastard boy who hooked up with his precious daughter, he simply followed Zhao Yi's tone and asked, "Then tell me, the big 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's be specific!" Lin Xudong seemed to want to expose Zhao Yi, and continued to ask.

Zhao Yi looked up at Lin Xudong, staring at his face with a scrutinizing gaze, and then sighed and said, "Okay." That's right, they are designing a smart product, named 'Smart Niu', the main function of this 'Smart Niu' is to understand the beginning of various music, and continue to sing!"

"So powerful?"

"Uncle Lin, I won't tell you, I have to go back!" Zhao Yi showed up the things in his hand and went back with Xiao Zhicheng.

Lin Xudong went home.

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

Zhao Hongjuan also poked her head out of the house, "Yes, I went out to buy vegetables just now, and I saw your two colleagues, standing downstairs." What kind of big shot is that?"

"A professor at the Academy of Sciences. ”

Lin Xudong felt that there was room to play, "Zhao Yi said that he came to discuss scientific research with him, and I asked him what he said about making a 'smart cow' and being able to understand all kinds of music, and I don't quite understand." ”

"Smart cow, listen to music?"

Lin Xiaoqing pondered carefully for a few moments, and immediately said a word in retrospect, "Play the piano to the cow?"

Lin Xudong was stunned.

Zhao Hongjuan couldn't help but laugh out loud.

The whole family pondered it.

Lin Xudong's face was flushed, and he turned around and was about to go to the door to put on his shoes, "This kid dares to scold me, I can't spare him!"

Zhao Hongjuan and Lin Xiaoqing laughed and went over to stop.

Zhao Hongjuan also said, "You said you, you didn't react at the time, and you were embarrassed to find someone, isn't that just playing the piano to the cow? Zhao Yi is such a smart child, talking about scientific research with the old professor, what do you always ask?"

"Playing the piano to the cow, this word is used well, it is very appropriate, you change your name when you come back, and you will be called Lin Xu Niu......"

Lin Xudong wanted to beat people when he heard it.

Lin Xiaoqing blinked, and suddenly felt a little worried about Zhao Yi, she picked up her mobile phone and sent a message, "My dad knows, you pay attention." ”

Soon the information came back.

"Lin Woman, you can protect me!"

Lin Xiaoqing looked at her phone and chuckled, pursed her lips and sent two words, "I hate it!"

......

Professor Liu has been working on 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, so Professor Liu simply divided the code into several 'functional modules' and marked them separately.

He looked closely at the functionality of the code, and the more he looked at it, the more interesting it became.

This camouflage and infiltration function is so powerful that it can be said to be able to break through most of the safety nets, and the existing security defense system is almost helpless against this kind of infiltration.

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

In addition to discussing the ports that can be penetrated by the code, the information that can be intercepted, etc., but also the divergent thinking is used to discuss what kind of functional programs can be hidden under the 'camouflaged' code, and how to directly invade the target server.

The discussion lasted an hour.

After eating something casually, Zhao Yi wrote a code program with special functions according to the things discussed.

Professor Liu was also watching from the sidelines.

Originally, Professor Liu was going to write while pointing out, but he found that he couldn't speak at all, and in the process of Zhao Yi's writing, his fingers almost didn't stop, and he saw that on the screen, lines of code were constantly increasing, and there was no pause at all.

Xiao Zhicheng came to take a look.

Xiao Zhicheng was a little unconvinced by Zhao Yi before, he was a doctoral student in computer science, and he felt that the level of a high school student must be limited, and it was a bit of luck to study a new algorithm, but he suddenly thought of a 'good idea'.

Now Xiao Zhicheng finds that he is wrong, not to mention any 'screening method' and 'hacking technology', in terms of the ability to write code, three or four of him together, it is estimated that he is not an opponent at all.

This speed?

Can't even compare to copying!

After Zhao Yi wrote the code, he ran and debugged, and 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, the subordinate website of our department, it doesn't matter, just say that I did it." ”

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

Zhao Yi entered separately.

After the program was officially running, he used another computer to find a proxy IP to open the target website.

Immediately a prompt popped up on the web page, "Please ask if the XXX program is loaded, from the website."

"Load!"

Suddenly a few blood-red words appeared on the computer screen: "Warning: Your computer has been infected with a virus!"

"It worked!"

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

Professor Liu was also very happy.

Xiao Zhicheng and his assistant stood on the side, looking stunned and feeling a little scary.

It's that simple?

They are also computer professionals, and they are also very familiar with computer technology, and they only know the open ports of the target website, and if they run a program on their own computers, users who visit the website will be infected with viruses?

Not a virus!

It's just a small animation program that calls the user's underlying function and executes it.

But it's scary to think about!

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

Zhao Yi looked at Professor Liu with an inquiring look.

Professor Liu went over and replied, "OK!"
