Shi Lei and Yi Zuer jointly completed the analysis of the worm virus that was rampant in the power grid system in Shuangqing City. Shi Lei discovered the general characteristic code of the worm virus and wrote a special killing tool.
Yi Zuer used special killing tools to quickly detect worm viruses in the power grid system of Shuangqing City. In the power grid system of Shuangqing City, nearly 1.4 million worm virus variants were reduced rapidly while Yi Zuer used special killing tools to detect worm viruses.
Fourteen minutes and twenty seconds later, Yi Zuer reminded Shi Lei that he had completed the detection and killing of the worm virus in the Shuangqing City power grid system, and scanned the power grid system in a comprehensive and deep manner, and no remaining worm viruses were found.
Shi Lei was about to tell Ling Yuguo this good news, but the virtual transparent screen of the lip lens-type information processor showed Yi Zuer's red warning message.
At the same time, Yi Zuer also used cold and emotional, but a quick voice to remind Shi Lei, "Sir, I found an unexpected situation and a large number of unknown signature worm viruses appeared in the power grid system. The specialized killing tool failed and the worm virus could not be detected. The analysis tool lost its function and the worm virus signature could not be analyzed."
Shi Lei's face was ***Novel: A sudden stuttering, an incredible look appeared in his eyes. Yi Zuer had just reminded that no worm virus was found in the power grid system. All worm viruses have been cleaned up by special killing tools. Why did the worm virus kill directly?
The situation in the power grid system of Shuangqing City, the Western General Administration of Cybersecurity also detected it. Ling Yuguo asked nervously on the phone: "Shi Lei, what is this situation? A large number of worm viruses appeared in the power grid system. Have you noticed it?"
Shi Lei said helplessly: "Uncle Ling, I discovered it! The expert on my side, the special killing tool I just made, has completely investigated and killed the worm virus in the power grid system, but the worm virus suddenly appeared again. The expert suspected that the mother of the worm virus was not in the power grid system, but was stored in other places."
Ling Yuguo frowned and said, "Impossible!"
"Why is it impossible?" Shi Lei analyzed, "Uncle Ling, think about it, if the worm virus is preserved in the power grid system, it will definitely be killed by special killing tools. Our network security experts of Mirui Technology Group, should you believe in their strength? Apart from the possibility that the worm virus's parent is not in the power grid system, is there any other possibility?"
Ling Yuguo thought carefully. "Shi Lei, do your security experts know about the power grid system? The power grid system is very closed! If the power grid system is in normal operation, there are still nodes connecting to the Internet system. But now the power grid is closed, and the power grid system is only connected to our Western General Administration of Network Security and the Cyber Security Intelligence Department of Beijing 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 Cybersecurity Intelligence Department or our Cybersecurity West..." Ling Yuguo's voice suddenly interrupted and exclaimed: "The worm virus is really in our Cybersecurity West General Administration! When we just entered the power grid system to analyze the worm virus, we were counter-invaded by the worm virus and infected some computers."
Shi Lei had the urge to curse. He asked speechlessly: "Uncle Ling, did you not isolate this part of the computer?"
Ling Yuguo denied: "Of course we have isolated it. However, it is difficult to guarantee that there will be no problems! If the worm has a hidden function, it will temporarily hide it. When you have cleaned up the power grid system, it will invade the power grid system again from the General Administration of Network Security of the Western Region. This possibility is not non-existent."
Shi Lei sighed, "Uncle Ling, wait a moment, I will discuss countermeasures with our security experts." After that, Shi Lei hung up the phone.
"Yu Er, repeat the previous work!" Shi Lei re-invested the work of analyzing the worm virus signature code, trying to discover the general signature code again.
Yi Zuer did not disappoint Shi Lei's trust. When Shi Lei re-produced analytical tools, analyzed worm viruses in large quantities, and found a general feature code, it took less than five minutes.
Shi Lei was familiar with the special killing tools, and then called Ling Yuguo, "Uncle Ling, our expert, has made special killing tools again. I will transmit the special killing tools to you. You will be checking and killing in the bureau's network, and we will check and killing in the power grid system."
"Okay!" Ling Yuguo said a little embarrassedly. The Western General Administration of Cybersecurity did not have any way to deal with these super high-end viruses.
The Taoist is one foot taller and the devil is one foot taller and it does exist in the Internet world. However, since most hackers are gods in the Internet and are weak in reality, they dare not make trouble in the Internet. If they are caught, they will be a dead rhythm.
The worm virus killing tool made by Shi Lei for the second time has higher detection efficiency and faster detection speed. According to Yi Zuer's calculation, it only takes about two minutes and twenty seconds to kill all the worm viruses inside the Shuangqing power grid system.
"Uncle Ling, you have no problem?" Shi Lei asked Ling Yuguo while checking the progress of the worm virus killing tool.
Ling Yuguo smiled bitterly and said, "We do have worm viruses here!"
Shi Lei also smiled bitterly, but comforted him: "Uncle Ling, don't worry, you can solve the worm virus in the power grid system immediately. This time, there should be no problem!"
"Well! I will send a special killing tool to the Cyber Security Intelligence Department, and ask them to be responsible for handling relevant personnel in the Shuangqing City power grid system, and also check and kill their computers." Ling Yuguo explained the situation and then added, "Don't worry, I said that this special killing tool was made by our Western General Administration."
Shi Lei breathed a little relieved, then smiled and said, "Uncle Ling, there is still one minute left to investigate and kill the power grid system."
"Yes." 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 investigation and killing progress of the worm virus specialized tool was completed, Shi Lei was waiting for Yi Zuer's feedback.
"Sir, the worm virus in the Shuangqing power grid system has been completely cleaned up by the system using special killing tools. After a comprehensive and in-depth scan of the system, there are no worm virus residues in the power grid system." Yi Zuer's report information is exactly the same as the last time.
However, the results were different. This time, after Yi Zuer reported the situation, no worm virus appeared immediately in the power grid system.
"Scan again in depth!" Shi Lei, who was worried, used a silent voice to instruct Yi Zuer. Shi Lei and Ling Yuguo were on the phone. Shi Lei's orders to Yi Zuer were all completed by silently reciting, otherwise they would be missed.
"Please wait, the system is scanning the Shuangqing City power grid system." Yi Zuer responded to Shi Lei.
Shi Lei was not worried about the worm virus reappearing, so he asked Yi Zuer to scan it for a second time just to prevent accidents. Shi Lei did not think that the worm virus could still be hidden, and then inexplicably drilled out.
As early as the beginning, Shi Lei checked the computer hardware of the power grid system, but did not find that the worm virus resided in the hardware. Therefore, he cleaned up the worm virus in the power grid system and cleaned up the worm virus of the Western General Administration of Cybersecurity. Even the Cybersecurity Intelligence Department used the worm virus special killing tool written by Shi Lei to check and kill it once.
This means that Shi Lei cut off all the root causes of the worm virus, and it is naturally impossible for the worm virus to break out again.
Just as Shi Lei was about to tell Ling Yuguo that the rescue operation of Shuangqing City's power grid system was successful, Yi Zuer suddenly issued a reminder.
"Sir, the system scans the power grid system and worm viruses appear. The worm virus is reproducing and mutating itself. There are currently more than 10,000 species. The second generation special killing tool has failed, and the second generation analysis feature code tool has failed." Yi Zuer reminded Shi Lei that the worm virus has made a comeback again.
Shi Lei's eyes showed an incredible look!
Shi Lei had clearly cut off all possible channels for worm viruses to invade, but the worm virus seemed to appear out of thin air and once again arrived at the power grid system of Shuangqing City.
"Damn it!" Shi Lei cursed angrily.
Ling Yuguo also said helplessly: "Shi Lei, is it a worm virus that was written into the hard disk boot area of the power grid system?"
"No, we have checked the guidance area a long time ago, and there is no worm virus. Moreover, even if there is a worm virus, the special killing tool targets the guidance area." Shi Lei denied Ling Yuguo's speculation.
"What about the cache area?" Ling Yuguo again put forward his opinion, "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 see if there will be problems in the cache area?"
Shi Lei also denied, "Not that, the cache area has also been checked, not a problem with the hard disk, nor is it a problem with other hardware, and there is no problem with the hardware."
Shi Lei is very confident that Shi Lei has checked the computer equipment included in the power grid system in Shuangqing City several times. Shi Lei is sure that it is impossible for the computer hardware in the power grid system to be cracked by the worm virus to store the worm mother body.
Although the hacker who made this worm virus is very likely to have such ability to break through the computer's hardware and store the worm virus in it, the hacker did not do so.
It is indeed a very high-end approach to hacking hardware through software, 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, it is not a problem for experts to crack the hardware storage worms.
Ling Yuguo was a little crazy, "Where could there be a problem in what place? It could not be a problem with the network cable?"
The speaker is unintentional, the listener is intentional!
Shi Lei's expression was a little stunned, and then he showed a look of relief...
