Chapter 94    The same day

As it turns out, Jiang Chuan’s concerns are not redundant.

At noon the next day, Liu Jianwei came as scheduled.

Jiangchuan was treating guests at a restaurant outside the east gate of Jiangbei University. He did not choose any high-end places, but just an ordinary small restaurant.

This store was recommended by Liu Ruyi. Although it is not big and the decoration is not luxurious, according to her, the dishes in this store taste very good.

"Xiao Ru!"

After Liu Jianwei came, he greeted him with a smile.

Jiang Chuan looked at him quickly. Liu Jianwei was about twenty years old. He looked very ordinary and medium-sized. He had no obvious characteristics and was not much different from other students.

After Liu Ruyi introduced her to both parties, Jiang Chuan stretched out his hand and smiled and said, "Please go there specially, thank you for your hard work."

Liu Jianwei seemed not expecting Jiang Chuan to be so formal, and he couldn't help but feel a little restrained, "It's okay, don't be polite, Xiao Rushi and I will definitely help if I can."

Jiang Chuan nodded and smiled, saying, "Since that's the case, I'm not polite, sit down and say."

After several people sat down, Liu Jianwei said, "Jiang Chuan, Xiaoru mentioned it to me yesterday and said that you want to inquire about hacking. What do you want to know specifically?"

Jiang Chuan smiled and said, "I'm not very proficient in computers. Some questions may be ridiculous. When you answer them, try to say more details."

"no problem!"

Liu Jianwei nodded cheerfully and said, "As long as I know, I will explain it clearly to you."

Jiang Chuan asked: "What I want to know is, if I want to invade the monitoring system of Jiangbei University and use this method to monitor someone, can I do it?"

Liu Jianwei was stunned: "Supervise others?"

Jiang Chuan smiled and said, "Don't get me wrong. I just want to know about it and don't plan to do this."

After hearing this, Liu Jianwei breathed a sigh of relief and said, "Our school's monitoring system is actually outsourced to an online technology company outside the school, and it is not specially customized, so you can completely hack it."

"Is it difficult?" Jiang Chuan asked.

"This also requires people to be divided."

Liu Jianwei said: "If it is just a matter of typing the keyboard for experts, it cannot be simpler. But if it is for beginners, it will be difficult. Maybe it will be discovered before you can get hacked."

Jiang Chuan smiled and said, "Your answer is too general."

Liu Jianwei said: "Then let me tell you this. As far as I can, if I want to hack the school's security monitoring system, it should be possible to do it within five minutes.

If you write the program in advance or find the backdoor, it may be shorter."

As soon as these words were spoken, Jiang Chuan couldn't help but laugh, "Then how should you judge your level? What level are you at in your major?"

He could already be sure that Liu Jianwei was completely the kind of person who was very dedicated to technology and was not very good at human nature.

But such people are often experts in their own field.

Sure enough!

Liu Jianwei thought about it seriously and said, "In our major, my level is probably a little higher than the middle, and it should not be the top one. Oh, I mean the hacker level.

Actually, how to say this? A powerful programmer may not be a good hacker.

But a great hacker must be a great programmer. Can you understand if I say that?"

Jiang Chuan nodded and smiled, "I probably understand."

"So, for a master, our school's security system is almost like it's not on guard."

Liu Jianwei said: "But if it is a server of the LAN on campus and a database, it will take some effort to hack it, because it was done by our school's masters themselves."

Jiang Chuan asked: "You just said that the security system of Jiangbei University was provided to an outside company?"

"right!"

Liu Jianwei said: "Actually, it's not too out of the way. The boss of the company is an associate professor in our school. He is a graduate supervisor. The company is run by him. In fact, the employees are all his graduate students.

A senior brother I know is in the associate professor's company. I heard from him that the associate professor is actually busy with big projects. Small projects like surveillance systems are all handed over to students like them, and there is only a little hard work.

Think about it, how could they work hard in this situation? I guess they just do it casually."

Jiang Chuan said thoughtfully: "That means that if a person's computer technology is still fair, it is easy to get into the surveillance system of Jiangbei University, right?"

"right."

Liu Jianwei nodded, he thought for a while and said, "I'll tell you a joke circulating in our hospital and you will understand it."

Some people say that the first thing that students in our college do after learning computers is to try to hack the various systems of our school.

According to incomplete statistics, most of the attacks on our school’s servers were done by our own students…”

Listening to Liu Jianwei talking about their academy with great enthusiasm, Liu Ruyi and Zhong Bei sat there with a smile. Although they were listening carefully, they obviously didn't understand.

Jiang Chuan was thinking.

"By the way, when you talk about the monitoring system, I suddenly remembered it."

When Liu Jianwei was about to be excited, he suddenly remembered something and said, "Just a while ago, our school's security system was invaded. The school is investigating it, and there is an announcement. You can see it at the forum of your school."

Hearing this, Jiang Chuan immediately asked, "Will you find out when the exact day it was hacked?"

Liu Jianwei said: "This does not need to be investigated. Our teacher just told this yesterday, and it was hacked last Wednesday."

Last Wednesday?

When Jiang Chuan heard this, his eyes narrowed.

Kidnapping is the date of birth, that day!

When Zhong Bei and Liu Ruyi heard this, their faces changed. They naturally remembered their own experiences very clearly.

"Then who do you think this matter will be done?" Jiang Chuan asked inadvertently.

Liu Jianwei blurted out: "Who else can do it? Boring people!"

Jiang Chuan immediately asked, "What does it mean?"

"Our school's security system is so delicious, there are loopholes everywhere, which is better than a sieve. There are people who are going to get rid of it. How boring do you think this person is!"

Liu Jianwei curled his lips disdainfully and said, "Of course, this guy may be a beginner. His hands are itchy. Just find a system to try it out."

This answer is not what Jiang Chuan wants to hear.

After pondering for a few seconds, Jiang Chuan asked, "You just said that the school is checking. In your opinion, can the school find it?"

"It must be impossible to find out!"

Liu Jianwei said: "It's been so long since I was born. The school announced it yesterday, which means that either they were too late or they didn't find anything. The announcement is to scare students."

Jiang Chuan smiled and said, "So sure?"

Liu Jianwei said: "If the school can find it, it will not be an announcement, but a punishment notice. In fact, the school's various systems have been hacked too many times, and the leaders are probably used to it, hehe..."

Jiang Chuan asked calmly: "If you ask me to check, can you find out who did it?"

"It's not easy for me to check it out."

Liu Jianwei shook his head and said, "The main reason is that time has passed too long. People must have erased the traces that should be erased. Now you can see the man's techniques and ideas. It is difficult to find the specific address."

Hearing this, Jiang Chuan couldn't help but frown and asked, "Then if I must continue to investigate, do you have a way?"

"There is a solution, but it's hard to say how effective it is." Liu Jianwei said.

"oh?"

Jiang Chuan immediately asked, "What's the solution?"

Liu Jianwei said: "This needs to pass the screening..."

Before he could finish his words, he suddenly reacted, looked at Jiang Chuan in surprise, and asked, "Jiang Chuan, why do you want to check this?"

Jiang Chuan smiled and said, "That's the matter..."

"I'm going to check it!"

Liu Ruyi suddenly spoke.

Jiang Chuan glanced at her, but the latter gave him a look of peace of mind.

"You want to check?"

Liu Jianwei asked in surprise: "Xiaoru, why are you looking up this?"

Liu Ruyi said without hesitation: "Half a month ago, the school student had a kidnapping case. You should have heard of it?"

Liu Jianwei said: "I heard someone mention that two girls were almost kidnapped, but what does this have to do with the hacking of surveillance monitors?"

As soon as these words came out, Jiang Chuan narrowed his eyes slightly.

Zhong Bei looked at him in surprise and then returned to normal again.

Only Liu Ruyi looked as usual and said, "The two people who were almost kidnapped will sit in front of you."

"You... are you two?!"

Liu Jianwei suddenly reacted and stood up suddenly, "Someone wants to kidnap you?!"
