HK1461 The Stubborn Worm!
.
Shi Lei and Izuer jointly completed the analysis of the worm virus running rampant in the power grid system of Shuangqing City. Shi Lei discovered the common signature of the worm virus and wrote a special killing tool.
Izuer used a special killing tool to quickly detect and kill worms in the power grid system of Shuangqing City. In the power grid system of Shuangqing City, nearly 1,400,000 variants of worms are rapidly decreasing due to the killing by Yizuer's special killing tools.
Fourteen minutes and twenty seconds later, Izuer reminded Shi Lei that he had completed the worm detection and killing of the power grid system in Shuangqing City, and scanned the power grid system in a comprehensive and in-depth manner, and found no residual worm virus.
Shi Lei was about to tell Ling Yuguo the good news, but the virtual transparent screen of the LIP lens-type information processor displayed a red warning message from Yizuer.
At the same time, Izuer also used a cold and emotionless voice to remind Shi Lei, "Sir, we found an unexpected situation, and a large number of worms with unknown signatures appeared in the power grid system. The special killing tool failed and could not detect and kill the worm. Analysis tool Ineffective, unable to analyze the worm signature."
Shi Lei's face froze, and his eyes showed an incredible look. Just now, Izuru clearly 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 viruses directly kill them?
The situation in the power grid system of Shuangqing City was also detected by the Western General Administration of Cyber Security. Ling Yuguo asked nervously on the phone: "Shi Lei, what's the situation? There are a lot of worms in the power grid system. Have you found it? ?"
Shi Lei said helplessly: "Uncle Ling, I found it! The expert on my side, the special killing tool I just made, has completely killed the worm virus in the power grid system. But the worm virus suddenly appeared again. The expert suspects the worm virus. The parent body is not in the grid system, but kept 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 the special killing tool. Our network security expert of Mirui Technology Group, you should Believe in their strength? Apart from the possibility that the parent body of the worm 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 it is in normal operation, the power grid system still has connection nodes with the Internet system. But now the power grid is closed, The power grid system is only connected to the Western General Administration of Cyber Security and the Cyber Security Intelligence Department of Beijing City. If the parent of the worm is not in the power grid system, where is it stored?"
Shi Lei thought silently.
"Could it be that the worm is stored in the Cyber Security Intelligence Department. Or is it our Cyber Security West..." Ling Yuguo's voice suddenly stopped and he exclaimed, "The worm is really in our Cyber Security West Administration! We have just entered the power grid system to analyze worms. When the virus was detected, it was counter-invaded by a worm and infected some computers."
Shi Lei had the urge to curse. He asked speechlessly: "Uncle Ling, is this part of the computer. You didn't isolate it?"
Ling Yuguo denied: "Of course we have carried out isolation treatment. However, there is no guarantee that there will be no problems! If the worm has a hidden function, it will be temporarily hidden. When you have cleaned up the power grid system. Invading the power grid system again. This possibility is not impossible."
Shi Lei sighed, "Uncle Ling, wait a moment, I'll discuss countermeasures with our security experts." After speaking, Shi Lei hung up the phone.
"Izual, repeat the previous work!" Shi Lei re-invested in the work of analyzing the worm's signature, trying to find the common signature again.
Izuer did not live up to Shi Lei's trust. When Shi Lei made a new analysis tool, analyzed a lot of worms, and found a common signature, it took less than five minutes.
Shi Lei made the killing tool with ease, and then called Ling Yuguo, "Uncle Ling, our expert has made the killing tool again. I will send the killing tool to you. , we checked and killed in the power grid system."
"Okay!" Ling Yuguo said a little embarrassedly, for these ultra-high-end viruses, the Western Cyber Security Administration really has no way to deal with them.
The Tao is one foot high and the devil is ten feet high, and it does exist in the online world. However, since the vast majority of hackers are gods in the network and weak in reality, they also dare not make waves in the network. Lest you get caught, it will be a deadly rhythm.
The worm virus killing tool Shi Lei made for the second time has higher efficiency and faster killing speed. According to Yizuer's calculation, it only takes about two minutes and twenty seconds to remove the internal worms in the Shuangqing power grid system. The worms are all wiped out.
"Uncle Ling, is there any problem with your side?" Shi Lei asked Ling Yuguo while checking the progress of the worm virus killing tool.
Ling Yuguo smiled bitterly and said, "We really have worms here!"
Shi Lei also showed a wry smile, but comforted him: "Uncle Ling, don't worry, the worm virus in the power grid system can be solved immediately. This time, there should be no problems!"
"Yeah! I sent a copy of the killing tool to the Cyber Security Intelligence Department, and asked them to deal with the relevant personnel of the power grid system in Shuangqing City, and also check and kill their computers." Ling Yuguo explained the situation, and then He added, "Don't worry, this special killing tool, I said it was made by our Western General Administration."
Shi Lei breathed a sigh of relief, and then said with a smile, "Uncle Ling, in one minute, the investigation and killing of the power grid system will be completed."
"Yeah." Ling Yuguo relaxed in his heart.
This minute was as long as an hour, and Shi Lei kept an eye on the situation in the power grid system. When the killing progress of the worm virus killing tool was completed, Shi Lei waited for Izuer's feedback.
"Sir, the worm virus in the power grid system of Shuangqing City has been completely cleaned up by the system using the special killing tool. After a comprehensive and deep scan of the system, there is no worm virus left in the power grid system." Exactly the same.
However, the result was different. This time, after Izure reported the situation, the worm did not appear in the power grid system immediately.
"Deep scan again!" Shi Lei, who was worried, instructed Yizuer in a silent voice. Shi Lei and Ling Yuguo were on the phone, and Shi Lei's orders to Yizuer were all completed by silent recitation, otherwise they would be ganged up.
"Please wait, the system is scanning the power grid system of Shuangqing City." Yizuer responded to Shi Lei.
Shi Lei was not worried about the recurrence of worms, and asked Izuer to scan for the second time, just to prevent accidents. Shi Lei didn't think that the worm could be hidden, and then inexplicably came out.
As early as the beginning, Shi Lei checked the computer hardware of the power grid system, and found no worm resided in the hardware. Therefore, the worm virus in the power grid system was cleaned up, and the worm virus in the Western General Administration of Network Security was also cleaned up. And even the Cyber Security Intelligence Department used the worm killing tool written by Shi Lei to kill it once.
This means that Shi Lei has cut off all the roots of the worm, and naturally it is impossible for the worm to break out again.
Just when Shi Lei was about to tell Ling Yuguo that the rescue operation of the power grid system in Shuangqing City was successful, Yizuer suddenly gave a reminder.
"Sir, the system scans the power grid system to find worms. The worms are self-propagating and mutating. There are more than 10,000 types of worms. The second-generation special-killing tool is invalid, and the second-generation analysis signature tool is invalid." Izuer reminded Shi Lei, the worm is making a comeback again.
An incredible look appeared in Shi Lei's eyes!
Shi Lei has clearly cut off all possible channels for worms to invade, but the worms seem to appear out of thin air, and once again come to the power grid system of Shuangqing City.
"Damn!" Shi Lei scolded angrily.
Ling Yuguo also said helplessly: "Shi Lei, could it be a worm virus that was written into the hard disk boot area of the power grid system?"
"No, we have checked the guide area for a long time, and there is no worm. Moreover, even if there is a worm, the special killing tool will also target the guide area." Shi Lei denied Ling Yuguo's guess.
"Then what about the cache area?" Ling Yuguo raised his opinion again, "The power grid system is powered on all year round, and the cache area of the hard disk will not be emptied for a long time. Do you see if there will be any problems in the cache area?"
Shi Lei still denied, "No, the cache area has also been checked. It's not a problem with the hard disk. It's not a problem with other hardware. There is no possibility of a problem with the hardware."
Shi Lei is very confident. Shi Lei has checked the computer equipment included in the power grid system in Shuangqing City several times. Shi Lei has determined that it cannot be the hardware of the computer in the power grid system.
Although the hacker who created the worm probably had the ability to break into the computer's hardware and store the worm in it, the hacker did not.
Hacking the hardware through software is indeed a very high-end approach, but for experts of the same level, this approach is also equivalent to showing the weakness. As long as you pay attention to the problem of computer hardware, it is not a problem for experts to crack the method of hardware storage worm.
Ling Yuguo was a little mad, "Then what could be the problem? It can't be the problem of the network cable, right?"
He does not mean that!
Shi Lei's expression was taken aback for a moment, and then he showed a relieved look...
