Chapter 1994

Seeing that He Junchao turned on the operation mode without showing any signs of expression, everyone's attention was drawn to him in an instant.

Lu Weiwei squinted her eyes, and couldn't help laughing and said, "The policemen are big cows? I said He Junchao, why are the names of this group so strange?"

"What do you know?" Seeing that Lu Weiwei looked like she had never seen the world, He Junchao also laughed and said:

"Many of them are experts from the National Computer Virus Emergency Response Center, and most of them are from the police force."

"Where there are hackers, there are hongkees, right? If there are hongkees, there are policemen, right? We are just such a group of people. Anyway, if you have a problem, you can find them."

"Then you hurry up, don't be verbose." Master Xi seemed a little impatient.

After all, things are still unclear, and everyone is not at ease.

He Junchao smiled, and immediately began to make a briefing file of the type of virus he found, and sent it to the group, and all members of Aite.

Then He Junchao left a message in the group, letting these big cows see the situation of computer viruses, and asked some related questions.

With a large herd of more than 300 people, several enthusiastic group friends began to reply soon.

Lu Weiwei and Master Xi were not too clear about some technical terms.

At this moment, Police Officer Wang and Yuan Shasha, who got the news, even brought Jiang Xiaomi to the Furong branch.

Together with Liu Jingru and Wu Jun, Jiang Xiaomi could only sit on one side and wait quietly.

Officer Wang and Yuan Shasha hurriedly surrounded them, waiting for the result of He Junchao's consultation.

Not long after, He Junchao asked a general idea, and couldn't help but happily replied thank you in the group.

"How is it?" Seeing that He Junchao looked confident, Gu Chen hurriedly asked him.

"It can be traced back to some sources." He Junchao said.

Lu Weiwei couldn't wait, and continued to ask: "Can you be more specific?"

"To be more specific, do you understand?" Knowing that Lu Weiwei was just worrying, He Junchao glanced at her, and said leisurely as if he was a bigwig in the circle:

"To put it simply, I asked these friends about the types of computer viruses. They often deal with computer viruses, so they are quite familiar with the types of computer viruses."

"To put it simply, the computer virus we encountered this time is also very cunning. Of course, the computer virus's attack on the monitoring system of a small warehouse logistics center is by no means as simple as a direct attack."

"Then how did you attack?" Gu Chen asked.

He Junchao raised his head to think, and said slowly: "To put it simply, this computer virus will first control some network devices."

"For example, network servers, Internet terminals, network switches, telephone switches, routers, firewalls, etc."

"The hacker operated with his network attack platform, controlled network equipment, etc."

"From a purely technical level, technical analysis and source tracing are required, and this hacker basically uses a relatively common method, that is, to carry out the attack through some cover."

"And this hacker used a dozen springboard machines and proxy servers..."

"Wait a minute." Yuan Shasha seemed to be in a daze, and humbly asked for advice: "What the hell is this springboard machine?"

"The function of the springboard machine is limited to command transfer, which is to forward the springboard command from the upper level to the target system, so as to cover up the real IP of the hacker's attack." Hearing Yuan Shasha's remarks, Gu Chen explained directly.

He Junchao nodded silently: "Gu Chen is right. In fact, the operation method is very sophisticated. Hackers can often use some anonymous protection services to anonymize relevant domain names, certificates, and registrants, and some traceable information."

"In this way, inquiries cannot be made through public channels."

"So this requires us to investigate the source of the problem one by one, but fortunately, this hacker's technology is average, and it is not difficult to trace the problem."

"Fortunately, there are traces of these computer viruses in the records of the National Computer Virus Emergency Response Center."

"so……"

"So now it can basically be locked, and the guy who conducts the hacker attack should be in Jiangnan City."

"This guy used some springboards as cover, made a big circle, and finally attacked the monitoring system of the storage center."

Before Master Xi could finish speaking, He Junchao spoke with confidence.

Master Xi nodded silently and looked at Gu Chen.

Gu Chen analyzed and said: "Then according to Senior Brother He, the hacker's operating IP should be near us."

"Well, basically it can be locked. Many experts in the group have also helped us analyze it, because they have mastered the hacker's attack methods before."

"Because it is not a regular attack, the network has not been closed for the time being, and this time it was involved in a murder case, so some big cows in the group directly provided me with an IP."

"where?"

Hearing what He Junchao said, almost everyone was in unison.

After He Junchao clicked on the computer map, he found a location in an alley, pointed to a shop and said, "This is it."

"Fuyuan store?" Lu Weiwei narrowed her eyes and read out directly.

"It is this Fuyuan store, which is the source of the attack on the monitoring system of the storage center." He Junchao said.

"Is it reliable?" Looking at the small shop in the alley, Lu Weiwei couldn't help being suspicious.

But He Junchao said unhappily: "Lu Weiwei, are you doubting my ability?"

"That's not true." Lu Weiwei quickly retracted her words and explained:

"But, is this hacker the owner of the store? Or did the hacker use the computer in the store to attack the monitoring system of the storage center?"

"It's all possible." He Junchao said.

Master Xi was a little uneasy and said, "I'll take someone over there to have a look."

"I'll go with you." Gu Chen said.

Lu Weiwei also hurriedly said, "And me."

"What about us?" Liu Jingru asked.

"You guys go back first," Master Xi said.

Officer Wang also smiled and said: "Yes, Liu Jingru, you go back with Teacher Wu first, thank you for your help in covering."

"It's just that now, the contest between us and this black hand behind the scenes seems to be becoming more and more obvious."

"At this time, it depends on who makes the mistake first. What's more, we still have those bank accounts as chips in our hands. In short, we must find the mastermind behind the perpetrator."

"That's fine." Seeing that the police had their own plans, Liu Jingru glanced at the photographer Wu Jun.

Wu Jun also smiled lightly and said, "Then Xiaomi, you have to go too."

"Oh." Jiang Xiaomi couldn't help but sighed, and said helplessly, "I wanted to have dinner with my cousin, but it seems that she is busy."

"Xiaomi." Hearing Jiang Xiaomi's words, Master Xi stepped forward and said, "Looking at the current situation, we need to think long-term."

"The work of catching the mastermind behind the scenes is imminent, so I can't accompany you for dinner these few days, you go back first, we will make an appointment when you are free."

"Alright." Feeling that he was affecting his cousin's handling of the case, Jiang Xiaomi nodded silently, and said proactively:

"Then I won't bother you. How about we get together when this case is over?"

"Yes, I can't ask for more." Before anyone else could speak, Lu Weiwei quickly agreed.

Afterwards, Jiang Xiaomi, Liu Jingru, and Wu Jun walked out of the office one after another and returned to their respective workplaces.

As for Gu Chen, Lu Weiwei, Master Xi, and He Junchao, they drove to the Fuyuan store without stopping.

...

...

Fuyuan store is located in an alley at an intersection in the old city. The store is located under an old residential building and mainly deals in non-staple food.

When Gu Chen and the others drove to the door of Fuyuan store, they realized that it was a mini store.

It is said that it is a storefront, but it is actually equivalent to the basement of a residential building.

But because it is at an intersection, the passenger flow is okay.

When everyone stopped to observe, several customers who bought cigarettes happened to come out of the small shop.

A fat middle-aged man was sitting on a rocking chair at the moment playing with his mobile phone.

"The person who attacked the monitoring system of the storage center must be him?" Lu Weiwei couldn't help asking as she rolled down the car window.

Master Xi hesitated for a moment: "But this guy doesn't look like a hacker at all."

"Master Xi." He Junchao reminded after hearing Master Xi's remarks, "Don't forget, hackers are always behind the scenes, and never write the word 'hacker' on their faces."

"It's like a thief wandering the streets. It's impossible for someone to write the word 'thief' on their face, right?"

"The more ordinary this person is, the easier it is to be ignored. How do you know that someone who runs a small shop cannot be a hacker? You can't look at the surface of everything."

"Okay, okay, that's all I'll say." Master Xi didn't expect that He Junchao was also a chatterbox, so he hurriedly interrupted.

Gu Chen said slowly: "Go, go and have a look."

Then everyone got out of the car one by one and came to the door of the store.

The fat middle-aged man who was sitting in the rocking chair with his legs crossed and playing with his mobile phone also heard someone walk into the store, but he didn't make a sound.

People who buy goods here usually come to the counter to check out after taking the goods, so there is no need to say hello.

If you are an acquaintance, you will yell a few times when you enter the door.

Obviously, it was a stranger who came in this time.

However, it didn't take long for the middle-aged fat man to discover that four men and women wearing masks were standing in front of him at the moment.

Two of them were in police uniform and two were in civilian clothes.

The middle-aged fat man froze for a moment, and asked curiously, "Please... Excuse me, what do you want to buy?"

"Are you the owner of this store?" Gu Chen got straight to the point, and didn't want to play around with him.

The middle-aged man nodded silently, quickly sat up straight, and responded, "Yes, I'm the boss."

"Are you looking after the shop alone?" Lu Weiwei asked again.

The fat man hesitated, but still nodded silently, and asked again: "Comrade policeman, what's going on?"

"Do you usually go online?" He Junchao stepped forward and said.

"Go...to the Internet, everyone is online now, what's wrong?" Hearing He Junchao's words, the fat man felt a little ominous.

But He Junchao didn't hesitate, and asked directly: "Can you show me the computer you use to access the Internet?"

"Uh……"

The fat man hesitated and seemed to be very resistant.

Master Xi walked around the store before turning back. He also pointed to a computer bag behind the fat man and asked, "Is this your computer?"

"Yes... yes." Hearing Master Xi's words, the man became even more nervous.

Master Xi walked around the counter, walked up to the man, stretched out his right hand and hooked his fingers: "Can you show me?"

The scene was suddenly quiet for a few seconds, and the man nodded in agreement after repeated inner struggles, "Okay, here."

After taking the man's computer bag, Master Xi immediately opened it to check, then took out a high-end laptop and handed it to He Junchao who was beside him.

He Junchao took the computer and checked it back and forth, and then he couldn't help but sigh: "You use such a high-end computer? Do you usually use it to play games?"

"Yes... yes, I usually like to use this computer to play games." Listening to He Junchao's explanation to himself, the middle-aged fat man also told the truth.

"Hehe." He Junchao laughed dryly, and put the laptop on the counter directly, and then turned on the computer.

However, there is a lock screen password on the computer, but this is not a problem for He Junchao at all.

He Junchao simply operated on the keyboard, and the computer password was immediately unlocked.

After seeing this operation, the middle-aged fat man frowned slightly.

And all of this was seen by Gu Chen.

After He Junchao turned on the computer, he immediately began to search the man's computer.

The middle-aged fat man was a little nervous, and asked him curiously, "Comrade police, are you so interested in my computer? What are you doing?"

"You'll know later." He Junchao didn't have much communication with the middle-aged fat man, and kept typing on the keyboard with his ten fingers.

And it's getting faster and faster.

However, the faster the rhythm of typing on the keyboard, the more nervous the middle-aged fat man's heart was.

Gu Chen stood aside, quietly watching the changes in the expressions of the two parties.

Seeing the smile on the corner of He Junchao's mouth, Gu Chen basically guessed that the matter was settled.

"How about Senior Brother He?" Gu Chen asked.

"It seems that we have found the right person." He Junchao finished the operation, looked up at the middle-aged fat man in front of him, and asked, "What do you usually do besides opening a store?"

"No...it's nothing, just play badminton." The man said.

"No, what I said was related to computers." He Junchao corrected him.

But after a few seconds of hesitation, the middle-aged fat man hurriedly said again: "That's playing games, I like online games."

"Are you a hacker?" He Junchao felt that there was no need to go around with the fat man, so he said:

"We were recently investigating a case where the surveillance system at a warehouse was hacked."

"Finally, after our police traced the source in many ways, we found that the source IP of the computer virus attack on the warehouse monitoring system was your computer."

The voice fell, and the scene suddenly became quiet.

Most afraid of the sudden stillness of the air, the middle-aged fat man froze for a few seconds, then suddenly burst out laughing and said: "Comrade policeman, I think you must have made a mistake. I am a small shop owner. You said I used A computer virus attacked the monitoring system of the storage center?"

"Hehe, what are you kidding? How do I know this?"

"What degree do you have?" Gu Chen asked the fat middle-aged man right after he finished speaking.

The middle-aged fat man's expression was startled, and he was a little embarrassed to speak for a moment.

When Lu Weiwei saw this, she also said angrily: "Ask you? What education do you have? What major? Don't think that if you don't tell us, we won't be able to investigate. Hurry up."

I also heard Lu Weiwei hammering the table. A passing customer originally wanted to enter the store to buy something.

But look at the policeman's posture, and then look at the fat boss who looks like a schoolboy who made a mistake.

The customer suddenly hesitated again, and finally turned around and left, as if he felt that he came at the wrong time.

The middle-aged fat man felt a little guilty after being questioned like this by the police, but he still took the initiative to confess:

"I... I am a computer undergraduate."

"It really is a computer major." He Junchao was relieved when he got the man's reply, and said with a smile:

"However, a technology like yours is indeed powerful, and it can be used as a hacker. Tell me, why did you attack the monitoring system of that storage center?"

"I……"

"Tell the truth." Seeing that the man still wanted to argue, Gu Chen hurriedly added a reminder.

Obviously, in the current situation, the middle-aged fat man is not stupid.

The reason why the police were able to find this place shows that the police have computer experts who have traced it back to their own store through computer viruses.

At this time, he was still pretending to be innocent with the police, which was obviously too ridiculous.

Lu Weiwei also said angrily: "I said, what are you waiting for? The reason why we were able to find your store is that we have enough evidence to arrest you."

"Tell me, why did you attack the monitoring system of that storage center? Did you want to do it yourself? Or was someone instructing you to do it?"

"I also want to earn some extra money." Hearing Lu Weiwei's constant questioning, the middle-aged fat man lowered his head and said hesitantly:

"Actually, part of my usual income is to run this small non-staple food store, and part of it is to help people deal with some technical problems."

"Be more specific." Master Xi adjusted the law enforcement recorder, and also took out the notebook to ask him.

The middle-aged fat man nodded silently, and said truthfully:

"In fact, it is to accept orders online and help people deal with some technical problems remotely."

"Including network virus attacks?" Gu Chen asked him.

The middle-aged fat man was a little embarrassed, but he still nodded and admitted: "Yes, this kind of business is also included, but this kind of list is relatively rare, and it is difficult to meet."

"I was also a week ago when suddenly someone found me online and asked me to help with a technical problem."

"I asked at the time, was it a computer failure or something? But the other party kept silent and asked me to meet offline."

"Wait a moment."

Almost at the same time, just as the middle-aged fat man finished speaking, Gu Chen, Lu Weiwei, Master Xi and He Junchao.

The four spoke almost in unison.

This clue is really important, which shows that the middle-aged fat man has actually seen the mastermind behind the scenes.

Originally, Gu Chen was also very surprised, why is the mastermind behind the scenes a master hacker?

This made Gu Chen feel very headache for a while.

But now it seems that the other party has met the middle-aged fat man offline. Does this mean that the middle-aged fat man can accurately tell the other party's characteristics?

...
