Seeing He Junchao quietly turning on the operating mode, everyone's attention was instantly attracted to him.
Lu Weiwei squinted her eyes and couldn't help but said with a smile: "The big group of policemen? I mean He Junchao, why do these groups have such unusual names?"
"What do you know?" Seeing that Lu Weiwei looked like she had never seen the world, He Junchao also said with a smile:
"Many of them are experts at the National Computer Virus Emergency Response Center, and most of them are from the police force."
"There are hackers and there are Hongke, right? There are Hong Kong and there are police, right? We are just a group of people. Anyway, if you have any problems, you can go to them."
"Then hurry up and stop being nagging." Mr. Xi seemed to be impatient to wait.
After all, we still don’t have a clue about the matter, and everyone doesn’t feel at ease.
He Junchao chuckled and immediately began to compile the virus types he discovered into a briefing document and sent it to the group and all members of Aite.
He Junchao then left a message in the group to let these experts take a look at the situation of computer viruses and ask some related questions.
With a large group of more than 300 people, several enthusiastic members soon began to reply.
Lu Weiwei and Xi Ye were not too clear about some professional terms.
At this moment, after receiving the news, Officer Wang and Yuan Shasha, along with Jiang Xiaomi, came to Furong Branch.
Jiang Xiaomi, Liu Jingru and Wu Jun could only sit on one side and wait quietly.
Officer Wang and Yuan Shasha quickly gathered around and waited for the results of He Junchao's consultation.
It didn't take long for He Junchao to ask about it, and he couldn't help but happily replied in the group to thank him.
"How's it going?" Seeing He Junchao's confident look, Gu Chen quickly 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?"
"Do you know if you want to be more specific?" Knowing that Lu Weiwei was just worrying, He Junchao glanced at her and acted like a big shot in the industry, and said leisurely:
"To put it simply, I asked these friends about the types of computer viruses. They often deal with computer viruses, so they know the types of computer viruses quite well."
"To put it simply, the computer virus we encountered this time was also very cunning. Of course, a computer virus attacking the monitoring system of a small warehousing and logistics center is not as simple as a direct attack."
"What exactly was the attack?" Gu Chen asked.
He Junchao raised his head and thought, 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."
"This hacker used his network attack platform and controlled network equipment to operate."
"If we look at it purely from a technical perspective, it requires technical analysis and traceability, and this hacker basically used a relatively common method, which is to use some cover to carry out the attack."
"And this hacker used more than a dozen springboards and proxy servers..."
"Wait a minute." Yuan Shasha seemed to be confused by what she heard, 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, thereby concealing the real IP address of the hacker launching the attack." After hearing Yuan Shasha's words, Gu Chen explained directly.
He Junchao nodded silently: "Gu Chen is right. In fact, the operation methods are very sophisticated. Hackers can often use some anonymous protection services to anonymize some traceable information such as related domain names, certificates, and registrants."
"This way, inquiries cannot be made through public channels."
"So this requires us to investigate the traceability issues one by one, but fortunately, this hacker's technology is average, so the traceability problem is not difficult."
"Fortunately, these computer viruses are traceable in the records of the National Computer Virus Emergency Response Center."
"so……"
"So now we can basically target the guys who carry out hacker attacks. They should be in Jiangnan City."
"This guy took cover through some springboards, made a big circle, and finally attacked the monitoring system of the warehouse center."
Before Mr. Xi could finish what he said, He Junchao said it confidently.
Master Xi nodded silently and looked at Gu Chen.
Gu Chen analyzed it and said, "According to Senior Brother He, the hacker's operating IP should be near us."
"Well, it can basically be locked. Many experts in the group have also analyzed it for us, because they have mastered this hacker's attack method before."
"Because it is not a regular attack, we have not shut down the network for the time being, and this time it was involved in a murder case, so some big guys in the group directly provided me with the IP."
"where?"
After hearing what He Junchao said, everyone almost said the same thing.
After He Junchao clicked on the computer map, he found an alley, pointed to a store and said, "This is it."
"Fuyuan Store?" Lu Weiwei squinted her eyes and read directly.
"This is the Fuyuan store, and this is the source of the attack on the monitoring system of the warehousing center." He Junchao said.
"Is it reliable?" Looking at this small shop in the alley, Lu Weiwei couldn't help but become suspicious.
But He Junchao said angrily: "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 computers in the store to attack the monitoring system of the warehouse center?"
"It's possible." He Junchao said.
Mr. Xi said a little uneasily, "I'll take someone over to take a look."
"I'll go with you." Gu Chen said.
Lu Weiwei also quickly 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 and cover."
This chapter is not over yet, please click on the next page to continue reading! "Only now, the battle between us and the mastermind behind the scenes seems to be becoming more and more obvious."
"At this time, it all depends on who makes the mistake first. What's more, we still have those bank accounts in our hands as bargaining chips. In short, we must find the mastermind behind the murder."
"Okay." Seeing that the police had their own plans, Liu Jingru glanced at photographer Wu Jun.
Wu Jun also smiled lightly and said: "Then Xiaomi, you have to go too."
"Alas." Jiang Xiaomi couldn't help but sigh, and said helplessly: "I originally wanted to have dinner with my cousin, but it seems that my cousin is very busy."
"Xiaomi." After hearing Jiang Xiaomi's words, Mr. Xi also stepped forward and said: "Judging from the current situation, we need to take a long-term approach."
"The job of arresting the mastermind behind the scenes is urgent, so I can't eat with you these days. You can go back by yourself. We can make an appointment when you have time."
"Okay." Feeling that he was affecting his cousin's handling of the case, Jiang Xiaomi nodded silently and said proactively:
"Then I won't disturb you. How about we all get together after this case is over?"
"Okay, that's what I want." Before anyone else could say anything, 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 work units.
Gu Chen, Lu Weiwei, Master Xi and He Junchao drove to 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 sells non-staple food.
When Gu Chen and others drove to the entrance of Fuyuan Store, they discovered that it was a mini store.
It is said to be a store, but it is actually equivalent to the basement of a residential building.
But since it is at an intersection, the passenger flow is not bad.
When everyone stopped to observe, several customers buying cigarettes happened to come out of the store.
A fat middle-aged man was sitting on a rocking chair playing with his mobile phone.
"Isn't he the one who attacked the monitoring system of the storage center?" Lu Weiwei lowered the car window and couldn't help but ask.
Mr. Xi hesitated for a moment: "But this guy doesn't look like a hacker."
"Master Xi." Hearing what Master Xi said, He Junchao reminded: "Don't forget, hackers are always behind the scenes, and they will never write the word 'hacker' on their faces."
"Just like a thief wandering the streets, it's impossible for someone to have the word 'thief' written on their face, right?"
"The more ordinary a person is, the easier it is to be ignored. How do you know that someone who runs a small shop cannot be a hacker? Don't take everything at face value."
"Okay, okay, that's all I'll say." Master Xi didn't expect that He Junchao was also a talkative, so he quickly interrupted.
Gu Chen said slowly: "Let's go over and have a look."
Everyone then got off the car one by one and came to the door of the store.
A middle-aged fat man who was sitting in a rocking chair with his legs crossed and playing with his mobile phone also heard someone walking into the store, but he didn't make a sound.
When buying goods here, everyone usually takes the goods and comes to the counter to pay, so there is no need to say hello.
If you are an acquaintance, you will be greeted a few times when you enter the door.
Obviously, it was a stranger who came in this time.
However, it didn't take long before the fat middle-aged man discovered that four men and women wearing masks were standing in front of him.
Two of them were wearing police uniforms and two were wearing civilian clothes.
The fat middle-aged man was stunned for a moment and asked out of curiosity: "Please... may I ask, 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 beat around the bush.
The middle-aged man nodded silently, quickly sat upright, and responded: "Yes, I am the boss."
"Are you the only one looking after the store here?" Lu Weiwei asked again.
The fat man hesitated a little, but still nodded silently and asked: "Comrade police, what's going on?"
"Do you usually go online?" He Junchao stepped forward and said.
"Go...online, everyone is online now, what's wrong?" Hearing what He Junchao said, the fat man had an ominous premonition.
But He Junchao didn't hesitate and asked directly: "Can you show me the computer you use to access the Internet?"
"Well……"
The fat man hesitated a little and seemed to be very resistant.
After Mr. Xi walked around the store, he turned back and pointed at a computer bag behind the fat man and said, "Is this your computer?"
"Yes...yes." After hearing Master Xi say this, the man suddenly became more nervous.
Mr. Xi walked directly 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. After a period of inner struggle, the man nodded in agreement: "Okay, here you go."
Taking the man's computer bag, Mr. Xi immediately opened it to check, then took out a high-end laptop and handed it to He Junchao who was standing aside.
He Junchao took the computer and checked it back and forth. 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, the middle-aged fat man also told the truth.
"Haha." He Junchao laughed dryly, put the laptop directly on the counter, 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.
I saw He Junchao simply operate on the keyboard, and the computer password was immediately unlocked.
After seeing this operation, the middle-aged fat man frowned slightly.
And all this was seen by Gu Chen.
After He Junchao turned on the computer, he immediately began to search the man's computer.
The fat middle-aged man was a little nervous and asked him out of curiosity: "Comrade police, are you so interested in my computer? What are you doing?"
"You'll know later." He Junchao didn't communicate much with the middle-aged fat man, and kept tapping the keyboard with his fingers.
And the speed is getting faster and faster.
However, the faster the rhythm of typing on the keyboard, the more nervous the middle-aged fat man became.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Gu Chen stood aside, quietly watching the changes in the expressions of the two parties.
When he saw the smile on He Junchao's lips, Gu Chen basically guessed that the matter was settled.
"How is Senior Brother He?" Gu Chen asked.
"It seems 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: "Besides opening a store, what else do you do?"
"No...nothing, just playing badminton or something." The man said.
"No, what I'm talking about is related to computers." He Junchao corrected him.
But the middle-aged fat man hesitated for a few seconds and then quickly said: "That's playing games. I like online games."
"Are you a hacker?" Feeling that there was no need to beat around the bush with the fat man, He Junchao put it bluntly:
"We are currently investigating a case in which the surveillance system of a warehouse was hacked."
"Finally, after our police traced the source through various means, we found that the source IP of the computer virus attack on the warehouse monitoring system was your computer."
After the words fell, the scene suddenly became quiet.
What he was most afraid of was that the air suddenly stopped. After being stunned for a few seconds, the middle-aged fat man suddenly burst into laughter and said: "Comrade police, I think you must be mistaken. I just open a small shop. You said I use
A computer virus attacks the monitoring system of the warehouse center?”
"Haha, are you kidding me? How do I understand this?"
"What is your education level?" As soon as the fat middle-aged man finished speaking, Gu Chen asked him quickly.
The fat middle-aged man looked stunned and felt a little embarrassed to speak.
Seeing this, Lu Weiwei also said angrily: "What are you asking for? What is your education level? What is your major? Don't think that we can't investigate if you don't tell us. 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 posture of the policeman, and then look at the fat boss opposite who looks like a pupil who made a mistake.
The customer immediately hesitated again, and finally turned around and left, as if he felt that he had arrived at the wrong time.
Being questioned by the police in this way, the middle-aged fat man felt a little guilty, but he still took the initiative to confess:
"I...I am a computer science major."
"Sure enough, I majored in computer science." When the man replied, He Junchao was relieved and said with a smile:
"However, a technology like yours is indeed powerful and can be used as a hacker. Tell me, why did you attack the monitoring system of that warehouse center?"
"I……"
"Tell the truth." Seeing that the man still wanted to argue, Gu Chen quickly added a reminder.
Obviously, given the current situation, the middle-aged fat man is not stupid.
The reason why the police were able to find this place shows that they have computer experts and have traced the computer virus back to their own store.
At this time, he was still pretending to be innocent to the police, which was obviously a bit ridiculous.
Lu Weiwei also said angrily: "I said, what are you waiting for? The reason why we found your store is that we have full evidence to arrest you."
"Tell me, why did you attack the monitoring system of that warehouse center? Did you want to do it yourself? Or was someone instructing you to do it?"
"I also want to make some extra money." Listening to Lu Weiwei's constant questioning, the middle-aged fat man lowered his head and said hesitantly:
"Actually, part of my usual income comes from running this small non-staple food store, and part of it comes from helping people deal with some technical problems."
"Be more specific." Mr. Xi adjusted the law enforcement recorder and took out the transcript to ask him.
The middle-aged fat man nodded silently and said truthfully:
"Actually, I just take orders online and help people deal with some technical problems remotely."
The middle-aged fat man was a little embarrassed, but he still took the initiative to nod and admitted: "Yes, this kind of business is also included, but this kind of orders are relatively rare and difficult to come across."
"It was also a week ago that someone suddenly found me online and asked me to help solve a technical problem."
"I asked at that time if it was a computer failure or something? But the other party never said anything and directly 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 of them said almost in unison.
This clue is really important, it shows that the middle-aged fat man has actually seen the mastermind behind the scenes.
Originally, Gu Chen was also wondering why the man behind the scenes was so thoughtful and a master hacker?
This gave Gu Chen a very headache for a while.
But now it seems that the other party actually met the middle-aged fat man offline. Does this mean that the middle-aged fat man can accurately describe the characteristics of the other party?
