Mr. Mu took out a slightly old USB drive from the drawer, which was obviously not as small and delicate as the USB drive that Su Yun took out before. However, Zhang Qiu found that this USB drive was actually worn with a red rope, and the length of the red rope was about the same as an ordinary pendant.

Zhang Qiu couldn't help but look at Mr. Mu's slender and white neck, tall and round chest, and the sexy collarbone exposed under the shirt, thinking that this USB drive couldn't have been taken down from that place, right?

Thinking about it like this, it seems that the entire USB drive has a body temperature, and there is a greasy smell from the tip of the nose, and Zhang Qiu's blood is a little hot.

At this time, Mr. Mu had already given up his seat to Zhang Qiu and motioned for him to sit in his place to repair the USB drive. Zhang Qiu came to his senses and knew what he should do, so he quickly plugged the USB drive into the computer. But I didn't sit in that seat, although the beauty had just stood up from above, and there was still a lingering fragrance, but the technician should have the appearance of a technician, and the first thing to do was to get straight to the point, not sit on a stool.

After inserting the USB drive, insert your own USB drive, drag the tools you need to the desktop, and start detecting them.

Thanks to the experience, it only took one step to determine whether it was the same problem as the previous USB drive, and the result was indeed the same as the previous USB drive. It's simple, it's tense, but it's much faster to get straight to the point.

After successfully isolating the virus, Zhang Qiu did not end it immediately, but started to do other things.

First, the system was tested to see if there were any viruses left and any backdoor vulnerabilities. The USB drive virus must have been infected from the computer, so it becomes necessary to check the computer.

After some inspection, Zhang Qiu found a virus residue. As long as this virus is present, any USB drive plugged into this computer will be infected. However, it is not certain whether the computer is the source of infection, and it may be infected to the computer by a toxic USB disk.

Zhang Qiu immediately isolated the virus and then continued to check. Soon he found a hidden super administrator account in the depths of the system. This account is usually invisible, but after being obtained by a hacker, it can have the highest privileges of the system. It's like the back door that Zhang Qiu left on Lin Lai's computer.

Immediately afterwards, Zhang Qiu also found a Trojan program hidden under this super administrator account, which is an IP-related Trojan. After analyzing it, it turned out to be similar to the Trojan horse he left on Lin Lai's computer, which was also a Trojan horse that was quietly controlled by the camera and then uploaded to a fixed address.

However, this Trojan horse is not much simpler than the Trojan horse written by Zhang Qiu, Zhang Qiu analyzed that the level of the Trojan author should be below himself, at most it is a national level. As far as the level of the Trojan itself is concerned, provincial technicians should be able to write it. However, relying on a piece of software, you can't really judge the true level of a technician, at most it can only be used as a measure.

Zhang Qiu quickly cracked the Trojan and conducted anti-tracking of the Trojan. I found that the end of the IP connection was not an external network, but an internal network address, and after entering which address, it was found that it was the web server of the official website of Fang Fei Yiren.

Even if a small company has an official website, it is a rented server, and there are generally a few who have their own independent server. However, the company is not large, but it is equipped with an enterprise-level server, which can be described as very luxurious.

The performance of this server reached 2.85Tflops, which is very powerful, and it is stronger than the web server of Susen University.

With such a high performance, on a small website with an average of only a few thousand visits per day and a peak of no more than 20,000, it is natural that more than 90% of the resources are idle most of the time. Although this server also manages the company's business system and office system server, these systems consume negligible resources.

Such an idle high-performance server is the favorite target of hackers, no wonder it attracts hackers, and even Zhang Qiu wants to be a broiler when he sees it.

Such a small company generally does not invite a special network security department, and even if it does, it will not be able to recruit any masters. Therefore, security and defense must be outsourced, which gives hackers a lot of opportunities.

After scanning, I found a hidden administrator account in the server system, but it was not a super administrator.

This hidden account manages a hidden partition, allocates a fixed 25% of the resources to this hidden partition to run, and also allocates 25%-80% of the dynamic performance to it. And this hidden partition,There are two encrypted text jiàn,One of the encryption is slightly weaker.,When you enter it, it's all video text jiàn.。

Zhang Qiu couldn't help but look at the camera clamped on the monitor, thinking that it was probably taken by this camera! Sure enough, beauties are always remembered!

Presumably for the sake of security, the hacker did not continue to leave the Trojan to point the text to a fixed IP. In fact, after having a background, there is really no need to specify IP transmission. That's just one move many times, exposing yourself.

Zhang Qiu didn't move it for the time being, but looked at another encrypted text. This article is much larger, and there are also active, and there are many external IPs accessed to it.

After a little investigation, I found that there were many mobile network types of IPs, and after analyzing the number of jù, most of them were game types. It seems that this is the hacker who used this part of the resources as a server for a mobile game, no wonder he has to allocate a fixed 25% of the resources.

Because there is only one hidden account, Zhang Qiu can be sure that the two encrypted texts are one person. I can't help but think that guy is a talent, borrowed someone else's server, and peeked at the beautiful boss of other people by the way.

Zhang Qiu did not deal with it for the time being, but simply wrote an implantable recording software. This software is very small, and can be implanted into the original text and become a piece of hidden code, which can automatically record the IP and other information connected to the text.

This kind of technology is the same technology as solving the USB disk virus just now, and it belongs to the unique secret given by the system's welfare, which is difficult for even world-class technicians to discover.

After doing this, Zhang Qiu knocked on the carriage, raised his head and said, "OK!" ”

After speaking, he picked up the mouse, opened the USB drive, and the text in it immediately appeared in the list.

"Mr. Mu, let's see if it's one of these texts." Zhang Qiu just opened the USB drive and didn't look at those texts.

Get out of the way a little, so that Mr. Mu can come over. And Mr. Mu probably saw Wen Jiàn restored, and he was a little anxious, so he immediately came over.

At this time, Zhang Qiu was moving his body, and he couldn't help but pretend to be with Mr. Mu, and just hit her side, and a unique woman's body fragrance mixed with the smell of perfume hit the end of his nose, almost making him bleed from his nose. And the elastic soft touch produced when the two collided made Xiao Zhang Qiu raise his head directly, making Zhang Qiu almost fall down with unsteady steps.

Mr. Mu naturally didn't react so much as Zhang Qiu, and said sorry casually, she had already sat down, picked up the mouse, and browsed the text.

"That's right! That's what these texts are! Thank you so much, Aki! Mr. Mu continued Su Yun's name and used a very affectionate title. But the first time I called like this, I was emotionally the same as calling a passerby, but this time I was a little excited and gentle, and I even had a little bit of the intimacy when Su Yun called Xiaoqiu.

It must be an illusion! This cold and glamorous boss actually called me Xiaoqiu so kindly. Zhang Qiu couldn't help touching his nose and said with a smile: "You're welcome, it should be!" At the same time, I said in my heart, I will collect the money at this time.

"By the way, Mr. Mu, I found the source virus in your computer, and the virus on your USB drive should be infected from this computer. After being infected with the virus, have you plugged the USB drive into another computer? If so, I'll help you kill the virus too. ”

"Yes! In order to determine whether there is a problem with the USB drive, I plugged in three computers, all of which are company computers. Su Yun said.

After speaking, she said again: "I want to ask, Xiaoqiu, how are you going to charge?" ”

"Restore fù number jù, 1 USB drive 10,000. There are two USB drives before and after, and my sister's one has already paid for it, so you can reimburse her. As for antivirus, it's better to give it away for free. Zhang Qiu said. Because when she was on the first floor before, Su Yun said "This is my brother", and unconsciously narrowed the relationship between the two, and now Zhang Qiu beat the snake with the stick and directly said "my sister".

In fact, every only child has more or less an illusion, and it would be nice to have an older sister (older brother) or younger sister (younger brother). And Zhang Qiu especially fantasized about how good it would be if he had a beautiful and gentle sister who loved him, or a sister who was cute and obedient and liked him.

And Su Yun inadvertently conforms to the image of his imaginary sister, although he still has some kind of intention for this sister to be inhumane.

"No problem." Mr. Mu said very simply, "Bring the check." ”

Just when she finished saying that there was no problem, a system prompt sounded in Zhang Qiu's head: "Su Yun's temporary task: to help others." Help Su Yun and solve the boss's troubles (completed). Reward: Fist and Foot Mastery (municipal). Extraction or not? ”

"Since it is already the eighth mission, now the system is at a critical point of upgrade. For the current task, the task can be manually submitted to the end. After the submission is completed, the second half of the tasks and rewards will be actively abandoned, and the system will be upgraded from level 0 to level 1, from the temporary system to the official system. Will I finish the task submission? ”

Zhang Qiu's mind was stunned. Can the system be upgraded? Unexpectedly, it is already the eighth mission, this is too fast and easy, right?

At this time, Su Yun took the check, and Mr. Mu directly wrote a check for 10,000 yuan and handed it to Zhang Qiu. Zhang Qiu didn't take it because he was still in a daze.

After seeing the check, he reacted, but still didn't take the check, but said, "Let's talk about it when the poison is done." ”

After saying that, he tacitly acquiesced to the end of the submission. Then a panel of upgrades will pop up, showing the tasks that have appeared, as well as the level of completion.

Of the eight tasks, two were not completed, and one was half completed, that is, five and a half were completed. 69% completion, 69 points, out of 100. Pass grades! (A score of 95 or more is excellent, a score of 80 or more is good, a score of 60 or more is a pass, and a score of 60 or less is a failure.) ）

Although I don't know what this passing grade is, as soon as I saw the results, Zhang Qiu had a bad premonition. With this passing grade, you are destined to lose something.

Thinking of this, he couldn't help but scold the system for cheating him, those two failed tasks were not because he didn't want to complete them, but because they disappeared before he started to do them; The other half of the task was abandoned under the inducement of the system.

But now there is no turning back from the bow, so I can only upgrade it head-on. After clicking Upgrade, the system will be suspended for 24 hours for upgrade activities. During the system outage, the acquired skills will still be valid, and all other functions will be suspended.

At this time, Mr. Mu had already pointed out to Zhang Qiu that it was those computers.
