Shi Lei and Yi Zuer jointly completed the analysis of the worm virus that was rampant in Shuangqing City's power grid system. Shi Lei discovered the common signature code of the worm virus and wrote a special killing tool.
Yizuer uses specialized killing tools to quickly detect and kill worm viruses in the power grid system of Shuangqing City. There are nearly 1.4 million worm virus variants in Shuangqing City's power grid system. Yizuer uses specialized killing tools.
With the tools to kill them, the number is decreasing rapidly.
Fourteen minutes and twenty seconds later, Yizuer reminded Shi Lei that he had completed the worm virus scan on Shuangqing City's power grid system, and scanned the power grid system comprehensively and in depth, and no residual worm virus was found.
Shi Lei was about to tell Ling Yuguo the good news, but the virtual transparent screen of the lip lens information processor displayed a red warning message from Yizuer.
At the same time, Yi Zuer also reminded Shi Lei in a cold and emotionless but urgent voice, "Personally, I found an unexpected situation. A large number of unknown signature worms appeared in the power grid system. The special killing tool failed and could not kill the worms. Analysis
The tool is useless and cannot analyze worm virus signatures."
Shi Lei's face froze, and there was an incredible look in his eyes. Yizuer had just reminded him that no worms were found in the power grid system. All worms had been cleaned up by special killing tools. Why did the worms come back directly?
The situation in Shuangqing City's power grid system was also detected by the Western Network Security Bureau. Ling Yuguo asked nervously on the phone: "Shi Lei, what is this? A large number of worms have appeared in the power grid system. Have you found any?
?”
Shi Lei said helplessly: "Uncle Ling, I discovered it! The experts here have just made a special killing tool that has completely killed the worms in the power grid system. But the worms suddenly appeared again. The experts suspected that the worms
The parent body is not in the power grid system, but is stored elsewhere."
Ling Yuguo frowned and said, "Impossible!"
"Why is it impossible?" Shi Lei analyzed. "Uncle Ling, think about it. If the worm virus is stored in the power grid system, it will definitely be killed by a specialized killing tool. Our network security experts from Mirui Technology Group, you should
Do you believe in their strength? Apart from the possibility that the parent body of the worm virus is not in the power grid system, are there any other possibilities?"
Ling Yuguo thought carefully, "Shi Lei, do your security experts know about the power grid system? The power grid system is very closed! If it is operating normally, the power grid system still has connection nodes to the Internet system. But now the power grid is closed.
The power grid system is only connected to our Western Network Security Administration and the Cyber Security Intelligence Department of the capital city. If the parent body of the worm is not in the power grid system, where is it stored?"
Shi Lei thought silently.
"Is the worm virus stored in the Cyber Security Intelligence Department, or is it our Cyber Security West..." Ling Yuguo's voice suddenly broke off, and he exclaimed: "The worm virus is really in our Cyber Security West Bureau! We have just entered the power grid system to analyze the worm
When the virus was detected, it was counter-intruded by the worm virus and infected some computers."
Shi Lei had the urge to curse, and he asked speechlessly: "Uncle Ling, didn't you isolate this part of the computer?"
Ling Yuguo denied: "Of course we have carried out isolation processing. However, there is no guarantee that problems will not arise! If the worm has a hidden function, it is temporarily hidden. When you have cleaned up the power grid system, it will be released from the Western Network Security Administration,
Invading the power grid system again. This is a possibility, but it does not exist."
Shi Lei sighed, "Uncle Ling, please wait a moment, I will discuss countermeasures with our security experts." After saying that, Shi Lei hung up the phone.
"Yizur. Repeat the previous work!" Shi Lei reinvested in the work of analyzing worm virus signatures, trying to discover common signatures again.
Yizuer lived up to Shi Lei's trust. When Shi Lei re-created the analysis tool and analyzed a large number of worm viruses, it took less than five minutes to find the common signature code.
Shi Lei made the special killing tool with ease, and then dialed Ling Yuguo's number, "Uncle Ling, our expert has made the special killing tool again. I will send the special killing tool to you. You will check and kill the network in the bureau."
, we investigate and kill them in the power grid system.”
"Okay!" Ling Yuguo said a little embarrassedly. For these ultra-high-end viruses, the Western Network Security Administration really has no way to deal with them.
It is true that the devil is as good as the devil in the Internet world. However, since most hackers are gods on the Internet and weak chickens in reality, they do not dare to cause trouble on the Internet. Otherwise, if they are caught,
That is the rhythm of death.
Shi Lei's second worm virus killing tool has higher killing efficiency and faster killing speed. According to Yizuer's calculations, it only takes about two minutes and twenty seconds to kill the worms inside Shuangqing City's power grid system.
All worms are gone.
"Uncle Ling, are you okay with it?" Shi Lei asked Ling Yuguo while checking the progress of the worm virus killing tool.
Ling Yuguo smiled bitterly and said: "There is indeed a worm virus here!"
Shi Lei also showed a wry smile, but comforted him: "Uncle Ling, don't worry, the worm virus in the power grid system will be solved soon. This time, there should be no problem!"
"Yes! I will send a copy of the special killing tool to the Network Security Intelligence Department and ask them to deal with the relevant personnel of Shuangqing City's power grid system and also check and kill their computers." Ling Yuguo explained the situation, and then
He added, "Don't worry, this special killing tool was made by our Western General Administration."
Shi Lei breathed a sigh of relief, and then said with a smile: "Uncle Ling, there is only one minute left, the power grid system will complete the investigation."
"Yeah." Ling Yuguo felt relieved.
This minute was as long as an hour, and Shi Lei was always paying attention to the situation in the power grid system. When the worm virus killing tool was completed, Shi Lei was waiting for feedback from Yizuer.
"Pr, the worm virus in Shuangqing City's power grid system has been completely cleaned up by the system using a special killing tool. After a comprehensive and in-depth scan of the system, there is no worm virus left in the power grid system." Yizuer's report information is consistent with the previous report.
Exactly the same every time.
However, the result was different. This time, after Yizuer reported the situation, no worm virus immediately appeared in the power grid system.
"Deep scan again!" Shi Lei, who was worried, ordered Yizuer in a silent voice. Shi Lei and Ling Yuguo were talking on the phone, and Shi Lei's orders to Yizuer were all completed silently, otherwise he would betray others.
"Please wait a moment, the system is scanning Shuangqing City's power grid system." Yi Zuer responded to Shi Lei.
Shi Lei was not worried about the reappearance of the worm and asked Yizuer to scan it a second time just to prevent accidents. Shi Lei did not think that the worm could hide and then come out inexplicably.
As early as the beginning, Shi Lei checked the computer hardware of the power grid system and found that the worm virus was not resident in the hardware. Therefore, the worm virus in the power grid system was cleaned up, and the worm virus in the Western Network Security Administration was also cleaned up.
Viruses. And even the Network Security Intelligence Department used a worm virus killing tool written by Shi Lei to kill it.
This means that Shi Lei has cut off all the sources of the worm, so it is naturally impossible for the worm to break out again.
Just when Shi Lei was about to tell Ling Yuguo that the rescue operation of Shuangqing City's power grid system was successful, Yi Zuer suddenly sent out a reminder.
"Pr, the system scanned for worms in the power grid system. The worms are multiplying and mutating on their own, and there are currently more than 10,000 types. The second-generation killing tool has failed, and the second-generation signature analysis tool has failed." Yizuer reminded.
Following Shi Lei, the worm virus came back again.
Shi Lei had an incredible look in his eyes!
Shi Lei had obviously cut off all possible channels for the worm to invade, but the worm seemed to appear out of thin air and once again descended on Shuangqing City's power grid system.
"Damn it!" Shi Lei cursed angrily.
Ling Yuguo also said helplessly: "Shi Lei, could it be that a worm virus was written into the hard disk boot area of the power grid system?"
"No, we have checked the boot area a long time ago, and there is no worm virus. Moreover, even if there is a worm virus, the special killing tool has targeted the boot area." Shi Lei denied Ling Yuguo's speculation.
"What about the cache area?" Ling Yuguo raised his opinion again, "The power grid system is constantly powered all year round, and the cache area of the hard disk will not be cleared for a long time. Do you think there will be any problems in the cache area?"
Shi Lei still denied, "No, the cache area has also been checked. It is not a problem with the hard disk. It is not a problem with other hardware. There cannot be a problem with the hardware."
Shi Lei was very confident. Shi Lei had checked the computer equipment contained in Shuangqing City's power grid system several times. Shi Lei was sure that it was impossible for the computer hardware in the power grid system to be cracked by the worm virus and store the worm virus' mother body.
Although the hacker who created the worm was very likely to have the ability to break into the computer's hardware and store the worm in it, the hacker did not do so.
Hacking hardware through software is indeed a very high-end approach, but for experts of the same level, this approach is equivalent to showing weaknesses. As long as you pay attention to the problems of computer hardware, you want to crack the hardware storage worm virus
The method is not a problem at all for experts.
Ling Yuguo was a little crazy, "Then what could be the problem? It can't be a problem with the network cable, right?"
The speaker has no intention, the listener has intention!
Shi Lei's expression was slightly startled, and then he showed a look of relief...
