614 Chapter 613-Logic Bomb (2)? [seeking subscription]

"Could it be that they both did bad things?" Zhang Chaoyang's first reaction was that Xiao Lin and Sun Yang absconded in fear of crime.He stared at Captain Zhang, trying to tell him this speculation.

But Captain Zhang didn't have any expressions, and called all the employees to the large conference room for a meeting step by step, announcing the details of the appointment.

He looked at the employees under the rostrum with a serious expression and announced the order issued by the head of the headquarters:

"Comrades, the server of the Longteng series of websites has been hacked, and the logic bomb has locked the hard disk sector of the server. Our comrades here are all responsible for this accident. Next, our working group will talk to you one by one. To understand the history and root cause of the accident."

Upon hearing this, there was a buzzing sound of discussion in the conference room.

"What does the hacker's compromise of the server have to do with us?"

"Yes. I'm a salesman and I'm not proficient in computer technology. Why do you want to make an appointment with me?"

"All of us are employees of Yiming Group. Could it be that we will destroy our company's website server?"

The employees present all had angry expressions, believing that Captain Zhang's actions hurt their self-esteem.

Seeing this scene, an expert in charge of restoring data knocked on the table of the rostrum, "Comrades, the situation is special this time. We suspect that it was espionage. I hope you can cooperate in your work and don't mistake yourself."

He told the employees present that his group can recover hard disk data through special means.As long as there are traces of crime, they can recover and will not frame a good person.

I heard that this incident has risen to the level of national security, and the employees present here calm down.

Of course, some of them are already in cold sweats, their hearts are beating wildly, and their faces pale and bow their heads.All this was recorded by the surveillance camera in the conference room.

…………

the other side.

Xu Zhenming gave Sister Han and Zhou Jiawei the responsibility of receiving customers and distributing the Suzaku III150 CPU. He and Gui Changshu have returned to the headquarters of Yiming Group.

The two of them got out of the car in a hurry and walked towards the temporary computer room of the computer center of Yiming Group.

"Group leader Xu, do you think this matter has something to do with some American organizations?" Gui Changshu asked Xu Zhenming with an anxious expression on the way.

However, if the source code of Longteng operating system and Longteng EDA software were stolen by Americans through special means, the consequences would be unimaginable.

But Xu Zhenming shook his head, "The Americans should not have participated in this matter. They are not fools, they will make trouble at the cusp of such trouble."

Having said that, Xu Zhenming was playing drums in his heart.He also cannot ensure that the Americans will participate in this matter.If you participate in it, the consequences of the "logic bomb" will be somewhat serious.

The two of them walked into the small building of the computing center with dignified expressions and met Guo Liansheng who had hurried out.

Guo Liansheng is proficient in computer hardware technology and is the most proficient expert in hard disk data recovery in Yiming's laboratory.His expression was very serious at this time, and he was hurrying with his head down.

"Head Hu, how is the situation?" Seeing Guo Liansheng walking towards him, Xu Zhenming quickly stopped him to inquire about the situation.

Guo Liansheng raised his head and looked at Xu Zhenming when he heard the words, and sighed, "Chairman, the situation is not very good. There is a problem with the hard disk array of the large computer, and our team is recovering the system boot hard disk data."

Hearing this, Xu Zhenming's forehead was suddenly covered with dark clouds.

The large computer in the computing center is the central brain of Yiming Group, and all the technical achievements of Yiming Group are stored in the hard disk sequence cabinet.If there is a problem with these hard disk serial cabinets, Yiming Group will lose a lot, and specific data cannot be used to describe the economic loss.

At this point, Xu Zhenming waved to Guo Liansheng, "Leader Guo, we should rescue the technical data first, not start the mainframe computer in a hurry." In his opinion, the technical data of the Yiming Group Company is important.

Xu Zhenming knew Guo Liansheng's ideas and wanted to restore the mainframe computer and the internal network of the Yiming Group Company.In this way, the internal production of Yiming Group can be resumed as soon as possible.But at such a moment, technical information is the most important, and we should put aside the restoration of production first.

After listening to Xu Zhenming's words, Guo Liansheng felt a lot more relaxed.

"Chairman, we have checked the backup hard disk sequence cabinet. Everything is normal, and the data has not changed." He stopped and introduced the inspection situation of his team members.

At the end, Guo Liansheng and Xu Zhenming asked for instructions: "I will get the instrument back immediately, and I am going to immediately restore the sector data of the boot hard disk, how about it?"

"Go." After listening to Guo Liansheng's explanation, Xu Zhenming was also much more relaxed.

"In this way, the power of this'logic bomb' is not very powerful. It is only aimed at booting the hard drive." He muttered with cold eyes, vowing to find out the details of the enemy and send the enemy to prison for a free lunch. .

While talking to himself, Xu Zhenming and Gui Changshu hurriedly climbed the stairs.Not long after, they have come to the central computer room of the computing center.

In the computer room, Director Yang and Chaonan Wang of the Computing Center are busy, crackling on the keyboard of the laptop to input instructions.

Seeing Xu Zhenming and Gui Changshu coming together, Wang Chaonan stopped work with an awkward expression and stood at attention and saluted: "Report! Good for the two chiefs. I have now obtained a specimen of the'logic bomb' and I am tracking its source."

Wang Chaonan is the network security specialist of the Longbow Group's resident at the Yiming Group's computing center. He is very responsible for this kind of incident and may also be punished.As a result, he was more nervous and spoke a little unnaturally.

Seeing his uneasy expression, Xu Zhenming shook his hand, "Don't panic, first introduce the situation of the'logic bomb' virus."

"Yes!" Wang Chaonan took a deep breath to calm the tension in his heart.He told Xu Zhenming that this "logic bomb" virus was a variant of Trojan horse virus.

"The enemy is very cunning. They split the'logic bomb' virus into more than a dozen pieces of program codes and lurked into our server in batches. When all the code programs enter the server, the'logic bomb' virus program is automatically assembled and started. Detonate, destroy the hard disk boot sector, and lock the sector."

Wang Chaonan pointed to his laptop screen, a program and a program report.

Hearing what he said, Xu Zhenming was rather happy!

This "logic bomb" virus looks more powerful and powerful, and it can paralyze the peripheral servers of Yiming Group.However, this bomb did not blow up all the data on the server's hard disk. Isn't it a good thing?

For Yiming Group, the data stored in the server hard disk is the most important.Thinking of this, Xu Zhenming said with a relaxed expression: "Wang Chaonan, your job now is to immediately restore the hard disk data of the network firewall workstation."

"Now I want the data of the network firewall workstation? Why?" Wang Chaonan looked at Xu Zhenming in surprise.

He knew that the master control program of the firewall workstation of the Yiming Group's intranet was written by Xu Zhenming himself. Is there any secret in this?

In fact, there is indeed a hidden existence.

Xu Zhenming was worried that the data in the intranet server of Yiming Group would be stolen, so he made a parallel workstation.There is a network log file in this workstation, which can record all the information of accessing the IP of the intranet server.In other words, as long as you access the Yiming Group's intranet server, you will leave traces and have nowhere to escape.

This kind of thing is a bit cautious, which means Xu Zhenming doesn't believe all the employees of Yiming Group.Under normal circumstances, he is unwilling to reveal this secret.But now in this situation, Xu Zhenming has no choice but to expose the secret.

Seeing surprised eyes from Gui Changshu, Director Yang and Wang Chaonan, Xu Zhenming explained with a wry smile:

"The data stored in the intranet server of our group company is very important, such as the source code of the Longteng operating system, the source code of the Longteng EDA system, the source code of the CNC system of the five-axis CNC machine tool... etc. I have to be careful. "

"It should be done! We can't ensure that everyone will abide by the discipline." Gui Changshu is very supportive of Xu Zhenming's approach at this time.He believes that Xu Zhenming has done nothing wrong in order to protect the patented technology of Yiming Group.

But Wang Chaonan was a little embarrassed at this time."Xu Dong, let's put it this way, I went to the intranet server to play games privately, and you recorded it?" He blushed and asked Xu Zhenming.

"Of course, we will see the results in a while." Xu Zhenming nodded.

"Damn! It's smelly right now." Wang Chaonan scratched his head in embarrassment.

This action immediately betrayed his character as a child, and Gui Changshu and Director Yang couldn't help but laugh.

"Don't take this as an example, otherwise I will give you a serious punishment!" Director Yang ordered Wang Chaonan with a serious expression.

At this time, Gui Changshu was rejoicing in hardship, and he was still worried about the leak of the source code of the Longteng operating system.He waved to Wang Chaonan, "Hurry up and get ready, wait for the team leader Guo's team to recover the hard disk data, and immediately start checking the network log files."

"Yes!" Wang Chaonan saluted at once, and followed Guo Liansheng who had just walked into the computing center.

Guo Liansheng heard that the hard disk of the firewall working group was restored first, and immediately led the team members to get busy.

They disassembled the hard disk of the firewall workstation, inspected the hard disk in a vacuum and dust-free instrument, and read the number in a special way.This kind of technology is relatively advanced and is generally in the hands of hard disk R&D and manufacturing companies.

Two hours later, all data on the hard disk of the firewall workstation was read.Wang Chaonan ran a special program according to Xu Zhenming's instructions and began to check the content of the network log.

as predicted.

The enemy's attack on the Yiming Group's intranet service was revealed!

On March 21, 1996, from 3:10 to 3:12 pm, the user with ID number 202.192.01.035 accessed the intranet server, read the source code of the PP chat device, and stored a section of "network bomb" code.

On March 22, 1995, from 10:01 to 10:10 people, users with ID number 202.192.01.035 visited the intranet server, read the source code of the PP chat device, and stored a piece of "network bomb" code.

...

On April 29, 1995, from 16:51 to 16:59 pm, users with ID number 202.192.01.035 visited the intranet server, read the source code of the PP chatter, and stored a section of "network bomb" code.

After using this interview record, the enemy has actually been locked down and is an employee of the Yiming Group.
