HK1461 Stubborn worm!
. Shi Lei and Yi Zuer jointly completed the analysis of the worms rampant in the power grid system of Shuangqing City, Shi Lei discovered the general signature code of the worm, and wrote a special killing tool.
Yishuer used special killing tools to quickly check and kill worms in the power grid system of Shuangqing City. In the power grid system of Shuangqing City, nearly 1.4 million worm virus mutants are rapidly decreasing under the use of special killing tools by Yishuer.
Fourteen minutes and twenty seconds later, Yi Shuer reminded Shi Lei to complete 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 no residual worms were 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 Yi Shuer.
At the same time, Yi Shuer also reminded Shi Lei in a cold and emotionless, but hurried voice, "Sir, I found an unexpected situation, a large number of unknown signature worms appeared in the power grid system. The killing tool is ineffective and cannot detect and kill worms. The analysis tool is no longer effective and cannot analyze the worm signature. ”
Shi Lei's face froze, with an incredible look in his eyes, just now the Yi Er had clearly reminded that no worms were found in the power grid system, and all the worms had been cleaned up by special killing tools, why did the worms kill them directly?
The situation in the power grid system of Shuangqing City, the General Administration of Network Security in the West also detected it, and Ling Yuguo asked nervously on the phone: "Shi Lei, what is the situation?" In the power grid system, a large number of worms have appeared. Did you find out? ”
Shi Lei said helplessly: "Uncle Ling, I found out!" The expert on my side has just made zuò's killing tool. The worms in the power grid system have been completely killed, but the worms have suddenly appeared again. Experts suspect that the parent worm is not in the power grid system, but is saved elsewhere. ”
Ling Yuguo frowned and said, "Impossible! ”
"Why can't it be?" Shi Lei analyzed, "Uncle Ling, think about it, if the worm is saved in the power grid system. That would definitely be killed by the Killer Tool. Our cyber security experts at Mirui Technology Group, you should trust their strength, right? Is there any other possibility, other than the possibility that the parent body of the worm is not in the grid system? ”
Ling Yuguo thought carefully. "Shi Lei, do your security experts know about the power grid system? The power grid system is very closed! In the case of normal operation, the grid system also has the connection nodes of the zài and the Internet system. But now the power grid is shut down, and the grid system is only with our Cyber Security West Directorate. There is also the Cyber Security Intelligence Department of Jingcheng City. A network connection was made. If the parent body 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 Division, or is it our Cyber Security West..."Ling Yuguo's voice suddenly interrupted, and he exclaimed: "The worm virus is really in our Cyber Security West Bureau!" When we first entered the power grid system to analyze worms, we were counter-invaded by worms and infected some computers. ”
Shi Lei had an urge to scold. He asked speechlessly, "Uncle Ling, could it be that this part of the computer." You didn't quarantine you? ”
Ling Yuguo denied: "Of course we have been quarantined. However, there is no guarantee that there will be no problems! If the worm has a hidden function, it is temporarily hidden, and when you have cleaned up the power grid system, it invades the power grid system again from the General Administration of Cyber Security. This one is possible, and it is not that there is no zài. ”
Shi Lei sighed, "Uncle Ling, you wait a minute, I'll discuss countermeasures with our security experts." After finishing speaking, Shi Lei hung up the phone.
"Repeat what you did before!" Shi Lei returned to the work of analyzing worm signatures, trying to rediscover common signatures.
Yishuer lived up to Shi Lei's trust, and when Shi Lei remade the analysis tool, analyzed a large number of worms, and found the general feature code, it took less than five minutes.
Shi Lei made a special killing tool with ease, and then dialed Ling Yuguo's phone, "Uncle Ling, our expert, have done a good job of killing tools, I will send you the killing tools, you are in the bureau of the network to kill, we are in the power grid system to kill." ”
"Okay!" Ling Yuguo was a little embarrassed and said, for these ultra-high-end viruses, the General Administration of Cyber Security in the West really has no way to deal with them.
The road is one foot high, and the magic is one foot high, and there is indeed a zài in the Internet world. However, since the vast majority of hackers are gods in the network and weak chickens in reality, they do not dare to make waves in the network. Lest once caught, it will be the rhythm of death.
Shi Lei's second worm killing tool is more efficient and faster, according to Yi Zuer's calculations, it only takes about two minutes and twenty seconds to kill all the worms inside the power grid system of Shuangqing City.
"Uncle Ling, is there a problem over there?" Shi Lei asked Ling Yuguo while checking the progress of the worm killing tool.
Ling Yuguo smiled bitterly and said, "We really have worms here!" ”
Shi Lei also showed a wry smile, but comforted in his mouth: "Uncle Ling, don't worry, you can solve the worms in the power grid system immediately." This time, there should be no problem! ”
"Hmmm! 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 Shuangqing City Power Grid System, and also check and kill their computers. Ling Yuguo explained the situation, and then added, "Don't worry, this killing tool, I said that it was made by our Western General Bureau." ”
Shi Lei breathed a sigh of relief, and then said with a smile: "Uncle Ling, there is still one minute left, and the power grid system will complete the investigation." ”
"Hmm." Ling Yuguo's heart relaxed.
This minute is as long as an hour, and Shi Lei pays attention to the situation in the power grid system at any time. When the progress of the worm killing tool was completed, Shi Lei waited for the feedback from Yi Zuer.
"Sir, the worm of the Shuangqing City 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 are no worms left in the power grid system. "The information from the report is exactly the same as the last time.
However, the results were not the same, and this time, after Yishuer reported the situation, there were no worms in the power grid system immediately.
"Deep Scan Again!" Shi Lei, who was not at ease, used a silent voice to instruct Yi Zuer. Shi Lei and Ling Yuguo were on the phone, and Shi Lei's orders to Yi Shuer were all completed silently, otherwise they would be goofs.
"Please later, the system is scanning the Shuangqing City Power Grid System." Yi Shuer responded to Shi Lei.
Shi Lei was not worried about the recurrence of worms, so he let Yishuer scan it a second time, just in case of accidents. Shi Lei didn't think that the worm could still hide, and then inexplicably drill out.
As early as the beginning, Shi Lei checked the computer hardware of the power grid system, and found that the worm was not in the hardware. Therefore, the worms of the power grid system have been cleaned up, and the worms of the Western General Administration of Cyber Security have also been 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 root causes of worms, and it is naturally impossible for worms to break out again.
Just as Shi Lei was about to sue Ling Yuguo that the rescue operation of the power grid system in Shuangqing City was successful, Yi Shuer suddenly issued a prompt.
"Sir, the system scanned the power grid system to have worms, worms are multiplying and mutating on their own, and there are currently more than 10,000 species. The second-generation killing tool fails, and the second-generation analysis feature code tool fails. Yi Zuer reminded Shi Lei that the worm virus had made a comeback again.
Shi Lei had an incredible look in his eyes!
Shi Lei had obviously cut off all the channels for the possible invasion of worms, but the worms seemed to appear out of thin air and once again descended on the power grid system of Shuangqing City.
"Damn it!" Shi Lei scolded angrily.
Ling Yuguo also said helplessly: "Shi Lei, could it be a worm that has been written into the hard disk boot area of the power grid system?" ”
"No, we've checked the bootstrap area a long time ago, and there's no worm in it. Moreover, even in the presence of worms, the killing tool is targeted at the boot area. Shi Lei denied Ling Yuguo's speculation.
"What about the cache area?" Ling Yuguo once again put forward his opinion, "The power grid system is uninterrupted 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 problems in the cache area?" ”
Shi Lei still denied, "No, the cache area has also been checked, not the hard disk problem." It's not a problem with other hardware, and it's impossible to have a problem with the hardware. ”
Shi Lei is very confident that the computer equipment contained in the power grid system of Shuangqing City, Shi Lei has already checked several times, and Shi Lei determined that it is impossible to be the hardware of the computer in the power grid system, which was cracked by the worm, so as to store the worm matrix.
Although it is very likely that the hacker who created the worm had the ability to break into the computer's hardware and store the worm in it, the hacker did not do so.
It is indeed a very high-end practice to hack the hardware through the software, but for masters of the same level, such an approach is also equivalent to showing the weaknesses. As long as you notice the problem with the computer hardware, it is not a problem for the master to find a way to crack the hardware storage worm.
Ling Yuguo was a little crazy, "Then what is the problem that could be there, it can't be a problem with the network cable, right?" ”
The speaker has no intention, but the listener has the intention!
Shi Lei's expression was slightly stunned, and then he showed a relieved look....
(To be continued......)
PS: Guess where is the parent of the worm?
