.
Shi Lei and Izur jointly completed the analysis of the worm virus rampant in Shuangqing City's power grid system. Shi Lei found the common characteristic code of the worm virus and wrote a special killing tool.
Izur used the special killing tool to quickly check and kill the worm virus in Shuangqing City's power grid system.
In Shuangqing City's power grid system, nearly 1.4 million worm virus variants were rapidly reduced by Izur's special killing tool.
14 minutes and 20 seconds later, Izur notified Shi Lei that he had completed the check and kill of the worm virus in Shuangqing City's power grid system. He also did a comprehensive in-depth scan of the power grid system and did not find any remaining worm virus.
Shi Lei was about to tell Lingyuguo the good news, but the virtual transparent screen of the LIP lens information processor showed Izur's red warning message.
At the same time, Izur also used a cold and emotionless but urgent voice to remind Shi Lei, "Sir, an unexpected situation has been found. A large number of worm viruses with unknown characteristic codes have appeared in the power grid system.
The special killing tool has failed to detect and kill the worm virus.
The analysis tool has failed to analyze the worm virus' characteristic codes. "
Shi Lei's face stiffened, and his eyes showed a look of disbelief. Izur had just reminded him that no worm virus was found in the power grid system, and all the worm viruses had been cleared by the special killing tool. Why did the worm virus come back?
The situation in Shuangqing City's power grid system was also detected by the Western General Administration of Network Security. Lingyuguo asked nervously on the phone, "Shi Lei, what's the situation?
A large number of worm viruses have appeared in the power grid system. Did you find it? "
Shi Lei said helplessly, "Uncle Ling, I found it!
The experts on my side have just finished the special killing tool, and the worm virus in the power grid system has been completely eliminated, but the worm virus suddenly appeared again.
The experts suspect that the worm virus is not in the power grid system, but stored in other places. "
Lingyuguo 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 eliminated by the special killing tool.
You should believe in the strength of the network security experts of Mirui Technology Group, right?
Besides the possibility that the worm virus's mother is not in the power grid system, is there any other possibility? "
Lingyuguo thought carefully, "Shi Lei, do your security experts know about the power grid system?
The power grid system is very closed!
Under normal operation, the power grid system has a connection with the Internet system.
But now that the power grid is shut down, the power grid system is only connected with the Western General Administration of Network Security and Beijing's Network Security Intelligence Department..
If the worm virus's mother is not in the power grid system system, where is it stored in the power grid system? "
Shi Lei pondered in silence.
..... the worm virus is really in the Western General Administration of the Western General Administration of Network.................. ".................
........... infected............. infected................. infected
........... s.....................................
. "Lingyuguo denied," of course we did that.
But it's hard to guarantee that there won't be any problems!
If the worm virus has a hidden function, it can hide temporarily. When you finish cleaning the power grid system, it can invade the power grid system again from the Western General Administration of Network Security.
This is a possibility, but it's not impossible. "
Shi Lei sighed, "Uncle Ling, please wait for a moment. I'll discuss with our security experts about the countermeasures." After that, Shi Lei hung up the phone.
"Izur, repeat the previous work!"
Shi Lei re-immersed himself in the work of analyzing the worm virus's characteristic code, trying to find the universal characteristic code again.
Izur didn't disappoint Shi Lei's trust. When Shi Lei made a new analysis tool, it took less than five minutes to analyze the worm virus and find the universal characteristic code.
Shi Lei made a killing tool with ease and then called Lingyuguo, "Uncle Ling, our experts have made a killing tool. I'll send it to you. You can kill it on the network in the bureau, and we'll kill it on the power grid system."
"Alright!"
Ling Yuguo was a little embarrassed. The Western Cybersecurity Headquarters had no way to deal with such high-end viruses.
As the saying goes, 'As the saying goes, as the saying goes,' As the saying goes, as the saying goes, 'As the saying goes, as the saying goes,' As the saying goes, as the saying goes, 'As the saying goes, as the saying goes,' As the saying goes, as the saying goes, 'As the saying goes, as the saying goes,' As the saying goes, as the saying goes, 'As the saying goes, as the saying goes, as the saying goes,' As the saying goes, as the saying goes, 'As the saying goes, as the saying goes,' As the saying goes, as the saying goes, 'As the saying goes, as the saying goes,' As the saying goes, as the saying goes, 'As the saying goes, as the saying goes,' As the saying goes, as the saying goes, 'As the saying goes, as the saying goes,' As the saying goes, as the saying goes, 'As the saying goes, as the saying goes,' As the saying goes, as the saying goes, 'As the saying goes, as the saying goes, the
However, since most hackers were gods on the Internet and weaklings in reality, they did not dare to stir up trouble on the Internet.
Otherwise, once he was caught, he would be dead meat.
Shi Lei's second worm virus killing tool was more efficient and faster. According to Izur's calculation, it would only take about two minutes and twenty seconds to kill all the worms in Shuangqing City's power grid.
"Uncle Ling, is there any problem on your side?" Shi Lei asked Lingyuguo while checking the progress of the worm virus killing tool.
Lingyuguo smiled bitterly and said, "We really do have a worm virus here!"
Shi Lei also showed a bitter smile, but comforted him, "Uncle Ling, don't worry, the worm virus in the power system will be solved soon.
This time, there shouldn't be any problem! "
"Okay!
I've sent a copy of the killing tool to the Cybersecurity Intelligence Division and asked them to check the computers of the people in charge of Shuangqing City's power grid. "
Lingyuguo explained the situation and then added, "Don't worry, this killing tool was made by the Western Cybersecurity Headquarters."
Shi Lei was slightly relieved, then smiled and said, "Uncle Ling, there's still one minute before the power grid system is done."
"Okay." Lingyuguo felt relieved.
This one minute was as long as an hour. Shi Lei was paying attention to the power grid system's situation.
When the worm virus killing tool was done, Shi Lei waited for Izur's feedback.
"Sir, the worm virus in Shuangqing City's power grid system has been completely eliminated by the system using the killing tool.
After the system's comprehensive in-depth scan, there are no traces of the worm virus in the power grid system. "Izur's report was exactly the same as the last time.
However, the result was different. This time, after Izur reported the situation, the worm virus did not appear in the power grid system immediately.
"Do the in-depth scan again!" Shi Lei was still worried, so he ordered Izur with a silent voice.
Shi Lei and Lingyuguo were on the phone. Shi Lei's orders to Izur were all done silently. Otherwise, they would be exposed.
"Please wait, the system is scanning the power grid system in Shuangqing City." Izur replied Shi Lei.
Shi Lei was not worried about the worm virus appearing again. He asked Izur to do the second scan just in case.
Shi Lei did not think that the worm virus could hide and come out for no reason.
Early on, Shi Lei had checked the computer hardware of the power grid system. There were no traces of the worm virus in the hardware.
Therefore, the worm virus in the power grid system was eliminated, and the worm virus in the Western Cybersecurity Headquarters was also eliminated.
Even the Cybersecurity Intelligence Department used the worm virus killing tool that Shi Lei wrote to eliminate the worm virus once.
This meant that Shi Lei had cut off all the sources of the worm virus. Naturally, it was impossible for the worm virus to appear again.
Just as Shi Lei was about to tell Lingyuguo that the rescue operation of Shuangqing City's power grid system was successful, Izur suddenly sent a notification.
"Sir, the system has detected a worm virus in the power grid system. The worm virus is self-multiplying and mutating. Currently, there are more than ten thousand types.
The second generation of the killing tool has failed. The second generation of the analysis tool has failed. "Izur reminded Shi Lei. The worm virus was back again.
Shi Lei's eyes were filled with disbelief!
Shi Lei had clearly cut off all possible channels for the worm virus to invade, but the worm virus seemed to appear out of thin air and appeared again in Shuangqing City's power grid system.
"Damn it!" Shi Lei cursed.
Lingyuguo also said helplessly, "Shi Lei, could it be that the worm virus was written into the boot area of the power grid system's hard drive?"
"No, we have already checked the boot area. There is no worm virus.
Moreover, even if there is a worm virus, the killing tool only targeted the boot area. "Shi Lei denied Lingyuguo's guess.
"What about the cache area?"
Lingyuguo asked again, "The power grid system is not out all year round. The hard drive's cache area will not be emptied for a long time. Do you think there is a problem with the cache area?"
Shi Lei still denied, "No, the cache area has also been checked. It is not a problem with the hard drive.
It is also not a problem with other hardware. There is no problem with hardware. "
Shi Lei was very confident. Shi Lei had already checked the computer equipment in Shuangqing City's power grid system several times. Shi Lei was sure that it was impossible for the worm virus to crack the computer hardware in the power grid system to store the worm virus mother.
Although the hacker who created the worm virus was very likely to have the ability to crack the computer hardware and store the worm virus, this hacker did not do so.
Hacking the hardware through software was indeed a very high-end method. However, for an expert at the same level, this method was equivalent to showing the weakness.
As long as the problem with the computer hardware was noticed, it was not a problem for an expert to crack the method of storing the worm virus in the hardware.
Lingyuguo was a little crazy, "Then what could be the problem? It can't be the network cable, right?"
The speaker did not mean it, but the listener did!
Shi Lei was a little stunned, and then he showed a look of relief …
