Rule department scholar

These are all normal.

Professor Liu didn't care too much about his knowledge, but he still looked at it carefully, and asked Zhao Yi to help explain the functions.

soon.

Professor Liu couldn't stop laughing.

"This piece of code I designed for routing monitoring, as long as the routing security is not high..."

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

"Automatically destroy the program, I use the control to call the underlying clearing function of the target host to delete all the programs with suffixes..."

"There is also an invasion..."

"The camouflaged code can realize the intrusion port, and the access port opened by the general website can be camouflaged and infiltrated..."

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

Professor Liu was completely stunned.

Not only Professor Liu who was sitting next to him, but also his student Xiao Zhicheng, who is also a Ph.D. in computer science, stood behind the sofa, carefully looked at the content of the code, and couldn't help asking, "Are you sure you can Did it happen?"

"should be no problem."

Zhao Yidao, "I did a security penetration for the Zhengyang police, just to help check the security of their network. I successfully monitored their routing, and also 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 was almost time for dinner in the afternoon. Seeing that Professor Liu didn't intend to go out to eat, Zhao Yi simply strolled to a restaurant outside with Xiao Zhicheng, ordered a few dishes and had them delivered to his home. He also asked Xiao Zhicheng about his accommodation and confirmed that Liu The professor might stay here, so he bought a lot of toothbrushes, towels and the like.

When I went back with my things, the sky became a bit dark, a car chased up from behind, the window was lowered and a head poked out, "Zhao Yi!"

It's 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 glanced at Xiao Zhicheng, feeling more at ease in his heart, and asked with a smile on his face, "What's the matter, Uncle Lin?"

Lin Xudong also glanced at Xiao Zhicheng, pulled Zhao Yi aside, and asked in a low voice, "Who is in your house? Why do you ask our police to help keep an eye on it?"

"Staring?"

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

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

"Professor? Or from the Academy of Sciences?" Lin Xudong opened his mouth wide and asked in surprise, "Why do professors from the Academy of Sciences come to 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 that you can! You really can!" Lin Xudong said with a smile.

He does know that Zhao Yi has some kind of research, it seems to sound very powerful, very powerful, and it has been reported by various media, but it is difficult to connect a big man at the professor level of the Academy of Sciences with this bastard who hooked up with his precious girl At the same time, he simply followed Zhao Yi's tone and asked, "Then tell me, what is the great professor from the Academy of Sciences doing at your house?"

"Talk to me about scientific research."

"Scientific research, be more specific!" Lin Xudong seemed to want to expose Zhao Yi, and continued to ask.

Zhao Yi looked up at Lin Xudong, stared at his face with scrutiny, then sighed and said, "Okay. That's it, they are designing a smart product called 'Smart Aniu', this 'smart aniu' The main function of Ah Niu is to understand the beginning of various music, and to continue to sing along!"

"so smart?"

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

Lin Xudong returned home.

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

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

"A professor of the Academy of Sciences."

Lin Xudong felt that there was room for development. "Zhao Yi said that he came to discuss scientific research with him. I asked him what he said about making a 'smart cow' that could understand all kinds of music. I didn't quite understand it."

"Smart cow, listen to music?"

Lin Xiaoqing thought about it carefully for a few times, and immediately recalled a word, "playing the piano to a cow?"

Lin Xudong was stunned.

Zhao Hongjuan couldn't help but burst into a 'puchi' laugh.

The whole family thought about it.

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

Zhao Hongjuan and Lin Xiaoqing went over to hold her while laughing.

Zhao Hongjuan also said at the same time, "You said you, but you didn't realize it at the time, and you still had the nerve to go to someone. Isn't that just playing the piano with a cow? Zhao Yi is such a smart kid, talking about scientific research with the old professor, what do you always ask?"

"Playing the piano to a cow is a good and appropriate word. When you come back, you can change your name to Lin Xuniu..."

Lin Xudong wanted to beat someone up.

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

Soon the information came back.

"Nvxia Lin, you can protect me!"

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

……

Professor Liu has been studying the code.

The code designed by Zhao Yi is still somewhat 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 function of the code carefully, and the more he looked at it, the more interesting he found it.

This camouflage and infiltration 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 helpless against this kind of infiltration.

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

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

This discussion is one hour.

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

Professor Liu was also watching.

Originally, Professor Liu planned to write while pointing, but he found that he could not speak at all. During the process of writing, Zhao Yi almost kept his fingers, and saw that the lines of code on the screen continued to increase without any pause at all. when.

Xiao Zhicheng came over to have a look.

Before, Xiao Zhicheng was a little unconvinced towards Zhao Yi. He is a doctoral student in computer science, and he felt that a high school student must have a limited level, and it was a bit of luck to develop a new algorithm, but he suddenly thought of a 'good idea'.

Now Xiao Zhicheng found out that he was wrong. Not to mention the "screening method" and "hacking technology", as far as the ability to write codes, three or four of them together may not be opponents at all.

this speed?

I can't even copy it!

After Zhao Yi wrote the code, he ran and debugged it. He was going to use his own website. Professor Liu simply helped to make a URL, "Use this website, an information network of the Academy of Sciences, and a subordinate website of our department. It doesn't matter, just Say I did it."

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

Zhao Yi made input respectively.

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

Immediately a prompt popped up on the web page, "Would you like to load the XXX program from the website

"load!"

Suddenly, several large bloody characters appeared on the computer screen: "Warning: Your computer has a virus!"

"Success!"

Zhao Yi stood up happily, and waved his hands very vigorously.

Professor Liu is also very happy.

Xiao Zhicheng and his assistant stood aside, looking at it in a daze, feeling a little scary.

So simple?

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

Not a virus!

It is just a small animation program executed by calling the user's underlying function.

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? The official start at nine o'clock!"

Zhao Yi looked at Professor Liu with a questioning look.

Professor Liu replied in the past, "OK!"

Chapter 134 The whole network hangs eagles!Shock overseas!

"The main purpose of the confrontation between domestic and overseas cyber means is not to cause sabotage, but a kind of cyber technology deterrence, which is to clearly tell the other party that we have the ability to cause trouble for you."

"So everyone, don't make trouble for each other. If you make trouble for me, I will make trouble for you."

"We don't need to wreak havoc, no matter how much we do, we won't be able to enter the intranets of their important organizations. Similarly, they won't be able to enter our intranets either."

Professor Liu explained to Zhao Yi that the root of the cyber intrusion war at home and abroad is to tell him what kind of approach is the most suitable.

Zhao Yi understood.

Deterrence!

Let the other party know that they have the ability to cause damage. Isn't the newly designed intrusion program suitable?

The intrusion program completed by Zhao Yi and Professor Liu can be described as a kind of "automatically replicating network worm". The network worm can hang on the specific open port of the target website.

The requirements for "specific ports" are not high. Most of the websites that can be logged in are generally open, and there are many "environments" suitable for Internet armyworms.

The reason why network armyworms are called armyworms is because they do not need to invade the website, but stick to open ports. As long as the website transmits data to users, the armyworm will copy it once and stick behind the data. Follow the data packet into the user's computer.

Sticky worms can be blocked by firewalls and anti-virus software, but because the website data enters, the firewall and anti-virus software will act on the browser and will remind the user whether to run the program loaded by the target website. As long as the user chooses to load and run, sticky The worm can enter and run.

Of course.

If the firewall and anti-virus software do not protect the browser, the program can be loaded freely, and the armyworm can run directly when the user visits the website.

The ability of armyworms to attach to the server of the target website must be restricted. Most of its codes are used for camouflage, and only a small part of the codes are effective. It is difficult to achieve the effect of ordinary Trojan horses.

Zhao Yi's choice is to call the underlying functions of the operating system and use the most primitive code to load text on the screen.

There is still some time.

Professor Liu decided to join the intrusion as well. He carefully studied and perfected the intrusion code.

Zhao Yi simply used the original code to design the loaded picture. He used a large number of numbers to form an eagle shape. For reasons of aesthetics and drawing level, he compared the simple pictures on the Internet and constantly made corrections to make the eagle It looks more majestic.

This process is harder than designing code!

After eight o'clock, Zhao Yi opened MSN and had a pre-battle exchange with the members of the [-]th squad.

The players can't wait.

The group was full of messages from the team members, and they complained about how unreliable the captain was, and it was fine that he rarely went online at ordinary times, and it was almost time to attack, so he didn't go online earlier.

Zhao Yi made an embarrassing expression, and the group suddenly became quiet.

He continued to send a message and said, "Are you all ready? You can start now. The proxy has been opened. I will send you the URLs separately. You use software to detect open ports. Remember, you don't need to detect vulnerabilities, and you don't need to find other For information, I only need the IP of the website server and the open port number, and there must be a one-to-one correspondence."

Although Zhou Ming set the time at nine o'clock, the invasion was not about launching missiles, and he didn't say whether to switch on or off at a certain time.

As long as the proxy IP is open, it can be done freely.

The team still has a lot of questions --

"Captain, do you really don't want other information? Just IP and port number?"

"I used another IP before, and I have already collected part of the information, should I send it to you directly?"

"I found a website management portal, but I still haven't cracked the password! The cracker is not easy to use."
